offers many of the features of the ESS Model 800, but is based on a
two-way processor with 8 GB cache and 2 GB of NVS in contrast to the four
or six-way processors available with the ESS Model 800. With support for
up to 4.6 TB of physical capacity and six 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

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.

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:

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.

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
