The IBM 2105 is the IBM TotalStorage Enterprise Storage Server (ESS).
Model Abstract 2105-750
The ESS Model 750 is a new model in the family of Enterprise Storage
Servers. It provides an entry point into the ESS product family
comprised of the ESS Model 750 and the ESS Model 800. The ESS Model 750
offers many of the features of the ESS Model 800, but is based on dual
two-way processors with up to 16 GB cache and 2 GB of NVS in contrast to
the dual four or six-way processors available with the ESS Model 800.
With support for up to 4.6 TB of physical capacity and eight 2Gb Fibre
Channel/FICON or ESCON host adapters, the ESS Model 750 is designed to
provide an attractive price/performance balance for clients requiring
smaller configurations. The ESS Model 750 is well-suited for
environments where the workload access densities average two operations
per second per gigabyte.
The ESS Model 750 supports FlashCopy and FlashCopy Version 2, as well
as PPRC and PPRC Version 2, for point-in-time copy options and advanced
metropolitan or long-distance business continuance solutions. The ESS
Model 750 also includes support for zSeries performance enhancers; PAV,
priority I/O queuing, and multiple allegiance. Additionally, the ESS
Model 750 is upgradable to the ESS Model 800, offering clients'
investment protection and full ESS scalability.
The ESS is IBM's premier storage solution for use in Storage Area
Networks (SANs). It provides:
Support for the intermix of FICON (F10, F20), ESCON, Fibre Channel
and SCSI attachments, making the ESS a natural fit for storage and server
consolidation requirements.
Concurrent support for all your major server platforms, including
OS/390, OS/400, Windows NT, Windows 2000, NetWare, and many varieties of
UNIX.
Disk drive capacity intermix support providing extensive flexibility
with a vast number of configuration options so price, performance, and
capacity can be optimized to meet specific server and applications
requirements -- all within a single ESS.
Excellent scalability from 420 GB to over 1.6 TB (E10), 11.2 TB
(E20), 3.3 TB (F10), 22.4 TB (F20) of RAID-5 effective capacity.
Advanced Remote Copy Services for your synchronous and asynchronous
backup and disaster recovery needs
Extensive StorWatch** management capability through the Web
ESS API to easily manage multiple storage devices (on select models)
Superior performance with options and innovations to meet your
changing requirements
High availability to support your e-business and other
mission-critical applications
Model Highlights 2105-750
The ESS Model 750 is based on the same architecture as the ESS Model
800 to support functionality, stability, and reliability. The ESS Model
750 includes:
Support for up to 64 disk drives and up to 4.6 terabytes (TB) of
physical capacity
Dual two-way processors with up to 16 GB of cache, 2 GB of Non
Volatile Storage (NVS), and support for up to eight Fibre Channel/FICON
or ESCON host adapters
Support for 72.8 GB and 145.6 GB 10,000 rpm drives which can be
intermixed and configured as RAID 5, RAID 10, or a combination of both
FlashCopy and Peer-to-Peer Remote Copy (PPRC) options to help meet
business continuance requirements
Parallel Access Volumes (PAV), priority I/O queuing, and multiple
allegiance for enhanced IBM eServer zSeries performance
The ability to upgrade to the ESS Model 800, providing investment
protection
Today's global, e-business environment is increasing the demand for
fast and reliable access to data 24 hours a day, 7 days a week. However,
economic conditions mandate expenses to be kept low in order to maintain
a competitive bottom-line. The IBM TotalStorage Enterprise Storage
Server (ESS) Model 750 sets yet another milestone in ESS functionality,
flexibility, and overall value. It is designed to help meet the needs of
clients who don't require the full range of capacity and performance
scalability offered by the ESS Model 800, but do need enterprise level
functionality intended to support reliable, continuous access to data at
an affordable price.
Attractive price/performance for the small enterprise
The ESS Model 750 is designed to extend the functionality, stability,
reliability, and proven track record of the ESS product family to an
entry-level configuration.
The ESS Model 750 integrates dual two-way processors with 8 GB
cache and 2 GB of NVS. With support for up to 4.6 TB of physical
capacity and eight 2Gb Fibre Channel/FICON or ESCON host adapters,
the ESS Model 750 is designed to provide an attractive
price/performance for enterprises requiring smaller configurations.
The ESS Model 750 is well-suited for environments where the workload
access densities average two operations per second per gigabyte.
The ESS Model 750 can be configured as RAID 5, RAID 10, or a
combination of both. As a price/performance leader, RAID 5 offers
excellent performance for many customer applications, while RAID 10 can
offer better performance for selected applications. Price, performance,
and capacity can further be optimized to help meet specific application
and business requirements through the intermix of 72.8 GB or 145.6 GB
drives operating at 10,000 rpm.
The ESS Model 750 can help support 24 x 7 operations with a design
that seeks to reduce single points of failure through component
redundancy. The ESS Model 750 also supports advanced functions that can
help deliver business continuance solutions (FlashCopy and PPRC), as well
as FICON, PAV, multiple allegiance, and I/O priority queuing to offer
great performance in the zSeries and S/390 environments.
The ESS Model 750 is field upgradable, via a non-disruptive model
conversion, to the ESS Model 800. This can help extend the value of the
ESS Model 750 and opens a path to the full scalability and performance of
the ESS Model 800.
A variety of configuration options
Physical capacity for the ESS Model 750 is purchased via pairs of disk
eight-packs. A disk eight-pack contains eight disk drives, all which are
of the same capacity (either 72.8 or 145.6 GB) and rpm (10,000).
The ESS Model 750 supports the intermix of 72.8 GB and 145.6 GB
drives. With intermix support, a variety of configuration options are
available so that price, performance, and capacity can be better
optimized to meet specific application or business requirements.
For additional flexibility, feature conversions are available to
exchange existing disk eight-packs when purchasing new disk eight-packs
with higher capacity disk drives.
IBM Standby Capacity on Demand for ESS offering delivers storage
on demand
The IBM Standby Capacity On Demand for ESS offering (Standby CoD)
provides "standby" storage for the ESS and allows you to access the extra
storage capacity whenever the need arises. With Standby CoD, IBM will
install two Standby CoD disk eight-packs in your ESS for a nominal
charge. At any time, you can logically configure your Standby CoD
capacity for use -- a nondisruptive activity that does not require
intervention from IBM. Upon logical configuration, you will be charged
for the capacity.
IBM offers capacity on demand solutions that are designed to meet the
changing storage needs of rapidly growing e-businesses. Standby CoD is
designed to provide you with the ability to tap into additional ESS
storage and is particularly attractive if you have rapid or unpredictable
growth, or if you simply want the knowledge that the storage will be
there when you need it.
Contact your IBM representative or Business Partner to obtain
additional information regarding Standby CoD terms and conditions.
Flexibility with support for RAID 5 and RAID 10
With the ESS Model 750, physical capacity can be configured as RAID 5,
RAID 10, or a combination of both. RAID 5 can offer excellent
performance for most customer applications, while RAID 10 can offer
better performance for selected applications, in particular, high random
write content applications in the open systems environment. RAID 10
combines RAID 1 (mirroring) with RAID 0 (striping). Each drive within a
RAID 10 array is mirrored to a second drive within the array, and to
optimize performance, data is striped across the drives within the array.
The decision to configure capacity as RAID 5 or RAID 10, as well as
the amount of capacity to configure for each type, can be made at any
time. RAID 5 and RAID 10 arrays can be intermixed with an ESS (including
within an SSA loop) and the physical capacity can be logically
reconfigured at a later date (for example, RAID 5 arrays can be
reconfigured into RAID 10 arrays). To further support this flexibility,
advanced function licenses (for example, PAV, PPRC, and FlashCopy) are
purchased for the ESS Model 750 based upon the physical capacity of the
ESS, thereby, reducing the amount of pre-purchase planning and decisions,
and reducing the need to upgrade as capacity is logically reconfigured.
Extensive connectivity with 2Gb Fibre Channel/FICON support for
high performance SANs
The ESS Model 750 offers extensive connectivity support -- including
Fibre Channel, FICON, ESCON, iSCSI, and NAS -- across a broad range of
server environments -- including zSeries and S/390, IBM eServer pSeries
and RS/6000, IBM eServer iSeries and AS/400, IBM eServer xSeries and
other Intel-based servers, Sun and Hewlett-Packard. This rich support of
heterogeneous environments and attachments, along with the flexibility to
easily partition the ESS storage capacity among the attached environments
using the IBM TotalStorage Enterprise Storage Server Specialist (ESS
Specialist), helps support storage consolidation requirements and
dynamic, changing environments.
The ESS Model 750 further enhances this broad set of connectivity
options with support for 2Gb Fibre Channel and FICON. The 2Gb Fibre
Channel/FICON Host Adapters, which are offered in long-wave and
short-wave, auto-negotiate to either 2Gb or 1Gb link speeds. This
flexibility enables immediate exploitation of the benefits offered by
higher performance, 2Gb SAN-based solutions, while also maintaining
compatibility with existing 1Gb infrastructures. As 2Gb capability on
servers and fabric components is introduced into existing SANs, your
investment in ESS fibre adapters is protected and migration is
simplified.
IBM TotalStorage Resiliency Family
The IBM Total Storage Resiliency Family is comprised of IBM
TotalStorage Resiliency Core Technology, an extensive set of hardware and
software features and products, and IBM TotalStorage Resiliency
Automation, integrated software and services packages. The IBM
TotalStorage Resiliency Family is designed to help you implement storage
infrastructures to help keep your business running 24 hours a day, 7 days
a week.
The following ESS Model 750 functions are key components of the IBM
TotalStorage Resiliency Core Technology:
FlashCopy is designed to provide a point-in-time copy
capability for logical volumes. FlashCopy creates a physical
point-in-time copy of the data, with minimal interruption to
applications, and makes it possible to access both the source and target
copies immediately. FlashCopy is an optional feature for the ESS
(feature numbers 83xx).
FlashCopy Version 2 further supports business continuance solutions
with the following additional functions:
Data Set FlashCopy
Multiple Relationship FlashCopy
Incremental FlashCopy
FlashCopy to a PPRC primary
Additional enhancements:
Elimination of the Logical Subsystem (LSS) constraint
Establish time improvement
Consistency group commands
Inband commands over PPRC link
Data Set FlashCopy allows you to perform a FlashCopy of a data set in
zSeries and S/390 environments. This level of granularity allows for
more efficient use of your ESS capacity and can also help reduce the
background copy completion time since a FlashCopy no longer needs to be
performed at a volume level when a copy of selected data sets within a
volume is required. As with FlashCopy at the volume level, Data Set
FlashCopy is fully supported by z/OS Data Facility Storage Management
Subsystem (DFSMS).
With Multiple Relationship FlashCopy, a source can have FlashCopy
relationships with multiple targets simultaneously. This flexibility
allows you to initiate up to 12 FlashCopy establishes on a given logical
unit number (LUN), volume, or data set, without needing to first wait for
or cause previous relationships to end.
Incremental FlashCopy provides the capability to "refresh" a LUN or
volume involved in a FlashCopy relationship. When a subsequent FlashCopy
establish is initiated, only the data required to bring the target
current to the source's newly established point-in-time is copied. The
direction of the "refresh" can also be reversed, in which case the LUN or
volume previously defined as the target becomes the source for the LUN or
volume previously defined as the source (and is now the target).
Incremental FlashCopy can help reduce the background copy completion time
when only a subset of data on either the source or target has changed,
giving you the option to perform a FlashCopy on a more frequent basis.
Additionally, if no updates were made to the target since the last
"refresh", the direction change could be used to "restore" the source
back to the previous point-in-time state.
FlashCopy to a PPRC primary lets you establish a FlashCopy
relationship where the FlashCopy target is also a PPRC primary volume.
This enables you to create full or incremental point-in-time copies at a
local site and then use PPRC to copy the data to the remote site.
Additional enhancements:
Elimination of the LSS constraint: A FlashCopy source and target
relationship can span logical subsystems within an ESS. This flexibility
can help simplify administration and capacity planning for FlashCopy.
Establish time improvement: Performance improvements in FlashCopy
Version 2 are designed to provide up to a 10 times reduction in the time
required to complete a FlashCopy establish command (as compared to
FlashCopy). With this significant reduction in establish time,
operational interruption can be further minimized and the benefits of
FlashCopy can be extended into new application environments.
Consistency group commands: Commands are available to facilitate the
creation of FlashCopy consistency groups. With the FlashCopy Consistency
Group command, the ESS will hold off I/O activity to a LUN or volume
until the Flash Copy Consistency Group Created command is issued.
Consistency groups can be used to help create a consistent point-in-time
copy across multiple LUNs or volumes, and even across multiple ESSs.
Inband commands over PPRC link: In a PPRC environment, commands to
manage FlashCopy at the remote site can be issued from the local or
intermediate site and transmitted over the PPRC links. This eliminates
the need for a network connection to the remote site solely for the
management of FlashCopy.
FlashCopy Version 2 is an optional feature to the ESS (feature numbers
86xx). In addition to supporting the functions listed above, FlashCopy
Version 2 includes support for all functions offered with FlashCopy
(feature numbers 83xx).
Peer to Peer Remote Copy (PPRC) is designed to offer
hardware-based remote copy solutions. Synchronous PPRC (PPRC Metro
Mirro) is designed to provide real-time mirroring of logical volumes
between two ESSs that can be located up to 103 km from each other when
using ESCON communication links and up to 300 km when using Fibre Channel
communication links. It is a synchronous copy solution where write
operations are completed on both copies (local and remote site) before
they are considered to be done. PPRC also includes PPRC Extended
Distance (PPRC Global Copy), a non-synchronous long-distance copy option
for data migration and backup. PPRC is an optional feature to the ESS
(feature numbers 82xx).
PPRC Version 2 further supports business continuance solutions with
following additional functions:
PPRC over Fibre Channel links enables the use of Fibre Channel as the
communications link between the PPRC primary and PPRC secondary machines.
Compared to PPRC over ESCON links, PPRC over Fibre Channel allows a
reduction in PPRC link infrastructure, while delivering equivalent or
better performance. PPRC communication to the secondary control unit,
via Fibre Channel, provides for a much faster interface compared to
ESCON, particularly at long distances. Within a single machine, you can
run PPRC over both Fibre Channel and ESCON links, although the link type
cannot be mixed within the same LSS. The Fibre Channel ports used for
PPRC can be configured as either a dedicated PPRC link or as a shared
port between PPRC and Fibre Channel Protocol (FCP) data traffic.
PPRC Global Mirror is designed to provides a long-distance remote copy
solution across two sites using asynchronous technology. It operates
over high-speed, Fibre Channel communication links and is designed to
provide the following:
Support for virtually unlimited distance between the local and remote
sites, with the distance typically limited only by the capabilities of
the network and channel extension technologies. This can better enable
you to choose your remote site location based on business needs and
enables site separation to add protection from localized disasters.
A consistent and restartable copy of the data at the remote site,
created with minimal impact to applications at the local site. Compared
to Asynchronous Cascading PPRC (PPRC Metro/Global Copy), PPRC Global
Mirror eliminates the requirement to do a manual and periodic suspend at
the local site order to create a consistent and restartable copy at the
remote site.
Data currency where, for many environments, the remote site lags
behind the local site an average of 3 to 5 seconds, minimizing the amount
of data exposure in the event of an unplanned outage. Data currency is
also known as the recovery point objective (RPO). The actual lag in data
currency experienced will depend upon a number of factors, including
specific workload characteristics and bandwidth between the local and
remote sites.
Dynamic selection of the desired RPO based upon business requirements
and optimization of available bandwidth.
Session support whereby data consistency at the remote site is
internally managed across up to eight ESS machines located among the
local and remote sites.
Efficient synchronization of the local and remote sites with support
for PPRC failover and failback modes, helping to reduce the time required
to switch back to the local
PPRC Metro/Global Copy is designed to provide a long-distance remote
copy solution across three sites using a combination of PPRC Metro Mirror
and PPRC Global Copy. In a three-site configuration, the PPRC Metro
Mirro is maintained between an ESS at the local site and an ESS at an
intermediate site, while a PPRC Global Copy relationship is
simultaneously maintained between the ESS at the intermediate site and an
ESS at the remote site. When used with specific operational procedures,
this can be designed to provide a data protection solution in the event
of an unplanned outage at any one of the three sites. Alternatively,
operational procedures, including the creation of a "safety copy" at the
remote site using FlashCopy, can be used to design a solution that
provides a consistent copy of the data at the remote site in the event of
a regional outage affecting both the local and intermediate site.
PPRC Version 2 is an optional feature to the ESS (feature numbers
85xx). In addition to supporting the functions listed above, PPRC
Version 2 also includes support for all functions offered with PPRC
(feature numbers 82xx).
IBM performance innovations for the zSeries and S/390
environments
The ESS Model 750 supports the following previously introduced IBM
performance innovations for the zSeries and S/390 environments.
FICON extends the ESS's ability to deliver high bandwidth potential to
the logical volumes needing it, when they need it. Older technologies
are limited by the bandwidth of a single disk drive or a single ESCON
channel, but FICON, working together with other ESS functions, provides a
high-speed pipe with multiplexed operation.
Compared to ESCON, FICON offers increased per channel bandwidth that
supports significant improvements in single stream sequential throughput.
As a result, elapsed time for batch, data mining, or dump operations can
be substantially improved, providing potential relief for customers whose
batch or file maintenance windows are constrained.
The data rate offered by FICON during the data transfer portion of
response time is up to five times faster than ESCON, which can help
improve response time and reduce connect time. The larger the transfer,
the greater the typical reduction as a percentage of the total I/O
response time. FICON can also help reduce or eliminate the pend time
caused by busy director ports. For customers whose ESCON directors are
experiencing as much as 45-50% busy conditions, this can support
significant response time reduction.
Whereas ESCON channels can process only one operation at a time, FICON
channels can process multiple concurrent data transfers. When used with
PAV, FICON allows multiple data transfers to the same volume at the same
time over the same channel, providing greater parallelism and bandwidth
that can better exploit the maximum bandwidth of the ESS arrays better
than ESCON. Another performance advantage offered by FICON over ESCON is
that the ESS accepts multiple channel command words (CCWs) concurrently
without waiting for completion of the previous CCW.
Finally, significant performance advantages can be realized by those
customers who access their disk systems remotely. FICON can help reduce
or eliminate data rate "droop" for distances up to 100 km for both read
and write operations by using enhanced data buffering and pacing schemes.
PAV enables a single zSeries or S/390 server to
simultaneously process multiple I/O operations to the same logical
volume, which can help to significantly reduce device queue delays. This
is achieved by defining multiple addresses per volume. With Dynamic PAV,
the assignment of addresses to volumes can be automatically managed to
help the workload meet its performance objectives and minimize overall
queuing. PAV is an optional feature on the ESS.
Multiple allegiance expands the simultaneous logical volume
access capability across multiple zSeries or S/390 servers. This
function, along with PAV, enables the ESS to process more I/Os in
parallel, helping to improve performance and enabling greater use of
large volumes.
I/O priority queuing allows the ESS to use I/O priority
information provided by the z/OS or OS/390 Workload Manager to manage the
processing sequence of I/O operations.
Management tools and utilities improve administrator
productivity
The ESS Model 750 supports the following management tools and
utilities.
IBM TotalStorage Enterprise Storage Server Master Console (ESS
Master Console) provides single point of control
The ESS Model 750 utilizes the Enterprise Storage Server Network
(ESSNet), a dedicated LAN, to support configuration, copy services
communications between machines, call home, and remote support
capabilities. At the center of the ESSNet is the ESS Master Console,
which serves as a single point of control for up to seven ESSs. Multiple
ESSNets can also be interconnected and even connected into an enterprise
WAN to enable control of the ESSs from a central location, regardless of
where the machines may be located.
IBM TotalStorage Enterprise Storage Server Specialist (ESS
Specialist)
The ESS Specialist is a Web-based tool for performing logical
configuration and copy services (PPRC and FlashCopy) management
functions. The ESS Specialist is accessed via Web browser installed on
the ESS Master Console and can be accessed from other locations
throughout the enterprise if the ESSNet is connected into the enterprise
network. The ESS Specialist is provided with the ESS, at no additional
charge.
IBM TotalStorage Multiple Device Manager (MDM)
MDM provides centralized volume management, performance management,
and replication management for the ESS. MDM is an optional software
product.
IBM TotalStorage Enterprise Storage Server Expert (ESS
Expert)
The ESS Expert provides comprehensive asset, capacity, and performance
management information for the ESS. The ESS Expert is an optional
software product.
Command Line Interface (CLI) for PPRC and FlashCopy
The CLI enables open systems hosts to invoke and manage FlashCopy and
PPRC functions through batch processes and scripts. It provides commands
to query the status of ESS volumes and to execute copy services tasks
that were previously created using the ESS Specialist. The CLI is
provided with the ESS, at no additional charge. The CLI client is
available for the AIX, Dynix/ptx, HP-UX, NetWare, Solaris, Tru64 UNIX,
Windows NT, and Windows 2000 environments.
ESS Command Line Interface (ESS CLI)
The ESS CLI provides an alternate method to perform ESS logical
configuration and storage management functions. With the ESS CLI,
routine configuration and management tasks can be automated through their
incorporation into scripts and applications,helping to simplify ESS
administration and thereby reducing the total cost of ownership. The ESS
CLI is provided with the ESS at no additional charge. The ESS CLI client
is available for the AIX, HP-UX, Linux, Solaris, and Windows 2000
operating system environments.
ESS API
The ESS API supports routine LUN management activities, such as LUN
creation, mapping, masking, and the management of FlashCopy and PPRC. It
supports these activities through the use of a standard interface as
defined by the Storage Networking Industry Association (SNIA) Storage
Management Initiative Specification (SMI-S). The ESS API is implemented
through the IBM TotalStorage Common Information Model Agent (CIM Agent)
for the ESS, a middleware application designed to provide a CIM-compliant
interface. The interface allows Tivoli and third-party software
management tools to discover, monitor, and control the ESS. The ESS API
and CIM Agent are provided with the ESS at no additional charge. The CIM
Agent is available for the AIX, Linux, and Windows 2000 operating system
environments.
Subsystem Device Driver (SDD)
SDD provides load balancing and enhanced data availability capability
in configurations with more than one I/O path between the host server and
the ESS. Load balancing can help reduce or eliminate I/O bottlenecks
that occur when many I/O operations are directed to common devices via
the same I/O path. SDD also helps eliminate a potential single point of
failure by automatically rerouting I/O operations when a path failure
occurs, thereby supporting enhanced data availability capability. SDD is
provided with the ESS, at no additional charge. Fibre Channel (SCSI-FCP)
attachment configurations are supported in the AIX, HP-UX, Windows NT,
Windows 2000, and Solaris environments.
The ESS Model 750 and ESS Model 800 are designed to provide
performance, scalability, and flexibility to support 24 x 7 operations.
It is also designed to help provide the access and protection demanded by
today's business environment and to deliver the flexibility and
centralized management needed to lower long-term costs.
The ESS Model 750 can help provide clients, requiring entry-level disk
storage configurations, with an alternative to the high-performance,
highly scalable, but also higher priced ESS Model 800. The ESS Model 750
supports many of the same features and functions available on the ESS
Model 800, including point-in-time copy capability (FlashCopy),
comprehensive remote copy and disaster recovery capability (PPRC), and
zSeries performance enhancers (FICON, PAV, multiple allegiance, and I/O
priority queuing).
The ESS Model 750 is designed to provide entry-level capacity at an
attractive price and is specifically targeted to address the requirements
of the zSeries and open systems clients who have entry-level capacity and
performance requirements but want enterprise-level availability and
function. If you plan to replace previous-generation S/390 servers with
a new, small zSeries server, you will be interested in this product. If
you anticipate storage capacity requirements more than 4 TB over the next
three years, or have the need for higher performance, you should instead
consider the ESS Model 800.
As compared to the ESS Model 750, the ESS Model 800 offers increased
performance and scalability with up to 55.9 TB of physical capacity. The
ESS Model 800 is also capable of delivering higher performance and
throughput than the ESS Model 750 since it supports additional
processors, can be configured with more cache, and supports 15,000 rpm
disk drives. For that reason, you should consider the ESS Model 800 for
your performance scalability requirements (instead of the ESS Model 750).

Note: (1) Parts removed or replaced become the property of IBM and must
be returned.
Note: (2) When ordering the model conversion, the Standard Processor
feature (#3604) must be selected. Additionally, if the ESS Model 750 has
only two disk eight-pack features (#212x), a minimum of two additional
disk eight-pack features must be ordered.
The ESS is an intelligent disk system designed to provide
high-performance, high-availability, and high-capacity disk storage.
Physical view
The physical configuration of the ESS Model 750 consists of the
following components:
Base Enclosure: The base enclosure provides the rack and packaging
that contain host adapters, the cluster complexes, device adapters, and
power supplies, as well as, space for up to eight disk eight-packs.
Host adapters: Host adapters provide the I/O connections between
the ESS and server/fabric components. Up to eight ESCON or Fibre
Channel (SCSI-FCP and FICON) host adapters can be installed in an
ESS in any combination. The ESCON adapter has two ports; the Fibre
Channel adapter has one port. They are installed within four host
adapter bays (each cluster contains two bays) and can communicate with
either cluster (cache and NVS).
Cluster complex: The cluster complex (or just "cluster") provides
the management functions, including I/O processing, caching, data
transfer, and advanced functions, for the ESS. The ESS has two clusters
that are designed to operate independently to help optimize performance,
but also to provide redundancy to support high availability. In the
event of a cluster failure, the other cluster has the capability to take
over the function of the failed cluster.
A cluster is composed of the following components:
Cluster processor: The cluster processor executes Licensed Internal
Code (LIC) to manage and control the operations and advanced functions of
the ESS. Both clusters have a symmetrical multiprocessor (SMP).
Cache: Cache is designed to help improve performance by storing
frequently-accessed data so that it is available without disk access.
The ESS supports up to 16 GB of cache and it is equally divided between
each cluster. To help protect against loss of data on a write operation,
the ESS stores two copies of written data, one in cache and the other in
NVS.
Nonvolatile Storage (NVS): NVS is used to store a second copy of
write data to help protect against loss of data in the event of a cluster
or power failure. The ESS has a 2 GB NVS, which is split between the two
clusters. Data written to the cache in one cluster is written to the NVS
in the other cluster. A battery helps protect the data within the NVS in
the event of a total power outage.
External interfaces: Each cluster contains external interfaces,
including a CD-ROM, Ethernet connection, and IBM Customer Engineer (CE)
port, that are used to install and update LIC, perform configuration
management functions, and perform service operations.
Device adapters: Device adapters provide the connection between the
clusters and the disk drives. Each ESS has eight device adapters that
are configured in pairs (one in each cluster), with each pair supporting
two independent Serial Storage Architecture (SSA) loops with attached
disk drives. A loop consists of two physical links, one in each
direction, that each allow two read operations and two write operations
to be performed simultaneously by each adapter. Each device adapter
within a pair routinely manages access to half of the disk drives on a
loop. However, in the event of a device adapter or cluster failure, the
drives can be accessible by the other device adapter (and cluster).
Disk drives: The disk drives provide storage capacity for the ESS.
Disk drives are installed in disk eight-packs, a physical package of
eight disk drives of the same type (capacity and rpm). The ESS Model 750
supports up to eight disk eight-packs and up to 4.659 TB of physical
capacity. Disk eight-packs are available with 72.8 GB and 145.6 GB
drives (10,000 rpm).
Power supplies: The ESS has two AC/DC power supplies. External
power (three-phase) is provided to each AC/DC power supply through a
separate line cord and either power supply can support power requirements
for the entire ESS. The ESS also has a battery intended to provide
sufficient capacity to provide power for a fully configured ESS for a
minimum of 5 minutes if power from both line cords is lost.
Logical view
To supported servers, the ESS appears to be a set of disk volumes that
can be configured to emulate disk device types that are compatible with
the attaching servers.
The storage capacity of the ESS is logically divided into groups of
eight physical disk drives that are each configured as either a RAID 5 or
RAID 10 array. The array is logically formatted to support either:
Count-key-data (3380 or 3390 track format)
Fixed-block data (either 512 or 520 byte logical blocks)
Once formatted, the array is then subdivided into individual volumes
or LUNs that can be assigned to the various attached servers.
The ESS logical configuration is created and managed using the ESS
Specialist, ESS CLI, or ESS API.

and Planning Guide (GC26-7444) for capacity calculation guidelines.
ESS Advanced functions
Advanced functions are enabled and authorized based upon the physical
capacity of the ESS:
FlashCopy and FlashCopy Version 2
Enablement and authorization must be equal to or greater than the
total physical capacity of the ESS.
PPRC and PPRC Version 2
Enablement and authorization must be equal to or greater than the
total physical capacity of the ESS.
PAV:
Enablement and authorization must be equal to or greater than the
physical capacity within the ESS that will be logically configured as
Count Key Data (CKD) volumes for use with zSeries and S/390 servers.
Refer to the IBM TotalStorage Enterprise Storage Server Introduction
and Planning Guide (GC26-7444) for physical capacity calculation
guidelines. Refer to the IBM TotalStorage Enterprise Storage Server
Introduction and Planning Guide (GC26-7444) for physical capacity
calculation guidelines.
Standby CoD Disk Eight-Packs can be excluded from the physical
capacity calculation when the Standby CoD Indicator (feature number 9510)
is present on the machine.
Refer to "Ordering ESS Advanced Functions" at the end of the Special
Features section for ordering instructions.
The ESS Model 750 supports up to eight disk eight-packs (including
Standby CoD) and up to 4.659 TB of physical capacity. The valid
configuration options are shown below.
The ESS ships with IBM Licensed Internal Code (LIC) that is licensed
for use by a customer on a specific machine, designated by serial number,
under the terms and conditions of the IBM Customer Agreement or the IBM
Agreement for Licensed Internal Code.
The ESS Model 750 requires ESS LIC level 2.3.1, or later.
Not all ESS features and functions are available or supported in every
environment; current information on supported environments and minimum
operating systems levels is available at:
PPRC must be purchased for both the primary and secondary ESS. In
three-machine Asynchronous Cascading PPRC (PPRC Metro/Global Copy)
configurations, PPRC must also be purchased for the intermediate ESS.
PPRC requires the installation of at least one Fibre Channel/FICON or
ESCON host adapter on each ESS in the PPRC configuration to serve as the
PPRC communications link. For higher availability, IBM recommends that
more than one host adapter per ESS be used for the PPRC connectivity.
PPRC is supported with the use of SAN fabric products, ESCON
directors, Dense Wavelength Division Multiplexing (DWDM) products, and
channel extenders. A current list of supported environments,
configurations, networks, and products is available at:
Vendors should be consulted regarding hardware and software
prerequisites when using their products in an ESS PPRC configuration.
IBM is not responsible for third-party products.
When using channel extender products with PPRC, the channel extender
vendor will determine the maximum distance supported between the primary
and secondary ESS. The vendors should be contacted for their distance
capability, line quality requirements, and WAN attachment capabilities.
PPRC over Fibre Channel
PPRC over Fibre Channel communication links has the following
additional prerequisites:
PPRC Version 2
Fibre Channel/FICON Host Adapter (feature #3024 or #3025)
Asynchronous PPRC (PPRC Global Mirror)
PPRC Global Mirror has the following additional prerequisites:
ESS LIC level 2.4.0, or later
PPRC Version 2
Fibre Channel communications link
FlashCopy Version 2 on the secondary ESS. If PPRC Global
Mirror will be used during failback from the secondary ESS machine(s),
FlashCopy Version 2 must also be enabled on the primary machine(s).
In the event of a planned or unplanned outage, recovery procedures are
required to achieve a consistent and restartable copy of the data at the
remote site. Scripts and software can be used to help automate these
procedures.
PPRC Global Mirror is not supported in Asynchronous Cascading PPRC
(PPRC Metro/Global Copy) configurations as an alternative to the PPRC-XD
(PPRC Global Copy) relationship to the remote site.
PPRC Metro/Global Copy has the following additional prerequisites:
PPRC Version 2
PPRC Global Mirror is not supported in Asynchronous Cascading PPRC
(PPRC Metro/Global Copy) configurations as an alternative to the PPRC-XD
(PPRC Global Copy) relationship to the remote site.
DFSMS support for the FlashCopy Version 2 and PPRC Version 2
enhancements will vary depending upon the enhancement. z/OS and OS/390
PTFs are required to provide DFSMS support for Data Set FlashCopy,
Multiple Relationship FlashCopy, and elimination of the LSS constraint.
The IBM Support Center should be contacted for the current PTF
information.

License Upgrades
Upgrades to higher enablement and authorization levels should be
processed using the "Feature Exchange" option of the MSORDER transaction.
The upgrade will be priced as the delta between the current purchase
price of the ESS Function Authorization feature numbers added and
removed. The feature exchange must be processed against both the ESS
Model 750 8xxx feature number(s) and ESS Function Authorization 8xxx
feature number(s).
A feature exchange to a lower capacity level (a numerically lower
feature number) is not supported, with the following exception:
Within a given advanced function type, the #8x99 (0 TB (disable))
feature can be exchanged for any #8xxx feature. The feature exchange
must be processed against both the ESS Model 750 8xxx feature number and
ESS Function Authorization 8xxx feature number.
Upgrades from PPRC and FlashCopy (features #82xx and #83xx,
respectively) to PPRC Version 2 and FlashCopy Version 2 (features #85xx
and #86xx, respectively) should be processed using the "Feature Exchange"
option of the MSORDER transaction. The feature exchange can be made to
either the same or a higher capacity level. The upgrade will be priced
as the delta between the current purchase price of the features removed
and added. The feature exchange must be processed against both the ESS
Model 750 8xxx feature number and ESS Function Authorization 8xxx feature
number.
Downgrades from PPRC Version 2 and FlashCopy Version 2 (features #85xx
and #86xx, respectively) to PPRC and FlashCopy (features #82xx and #83xx,
respectively) is not supported.
Removal/Deactivation
The removal (deactivation) of an advanced function is processed using
a Feature Exchange to feature #8x99. The feature exchange must be
processed against both the ESS Model 750 8xxx feature number and ESS
Function Authorization 8xxx feature number.
No refund or credit is provided to the customer. Removal of an
advanced function is a disruptive activity and requires a machine IML.
