Model Abstract 3590-A50
(For IBM US, No Longer Available as of September 29, 2000)
The IBM TotalStorage Enterprise Tape Controller 3590 Model A50 is a
controller designed for attaching the IBM TotalStorage Enterprise Tape
Drive 3590 Models B11 and B1A to ESCON channels on ES/3090, ES/9000, or
S/390 systems. It can be installed in an IBM TotalStorage Enterprise
Automated Tape Library 3494, an IBM TotalStorage Enterprise Tape Drive
Frame 3590 Model A14, an IBM TotalStorage Silo Compatible Tape Drive
Frame 3590 Model C14, or standard 19" rack (such as the IBM 9309 Rack
Enclosure Model 002). It can also be attached as a free-standing unit to
an IBM TotalStorage Silo Compatible Tape Drive Frame 3590 Model C12. Its
performance is roughly double what was achieved in the predecessor IBM
TotalStorage Enterprise Tape Controller 3590 Model A00.
The Enterprise Tape Controller 3590 Model A50 improves 3590 tape
subsystem performance by incorporating IBM Seascape architecture. This
architecture combines powerful, proven, building blocks such as RS/6000,
AIX, and PCI bus architecture in a single control unit. Seascape's
building block approach enables the quick development cycles required to
respond to the marketplace in an agile way. The Model A50 exemplifies
this in how quickly it has been brought to market with performance
characteristics which remove bottlenecks typically found in tape
subsystems.
Utilizing the IBM Seascape building block approach further, the Model
A50 can be flexibly configured with one or two ESCON paths via adapter
cards. There is room for growth, too. Expansion card slots position the
customer to scale up or down to address ever changing business
requirements with a customer focused 3590 storage solution.
Finally, the Model A50 can coexist with its predecessor Model A00
Controller. This provides investment protection for Model A00 investors,
and enables an easy migration path to upgrade to the performance levels
provided by Model A50. The Enterprise Tape System 3590 demonstrates
IBM's continued commitment to providing advanced tape solutions to meet
the growing demands of the enterprise.
Model A50 Controller
The 3590 Model A50 Controller provides a high-performance ESCON
attachment of the 3590 Tape Drive to ES/3090, ES/9000, and S/390 systems
enabling:
Improved system throughput
Increased capacity
Investment protection
Reduced overall cost of storage
Increased maximum channel distance
Improved data integrity
Scalability for future growth
Enterprise Tape Library 3494 ESCON attachment

(ACS)
The Enterprise Tape System 3590 provides a tape drive data rate of up
to 14 MB/second, a capacity of 10 GB or 20GB (uncompressed) per
cartridge, and higher data integrity than 3480 products. The Model A50
provides a single data transfer path with one or two ESCON channel
adapters each with up to 64 logical channels and has a maximum channel
distance of 43 Km. It supports multiple logical paths per MVS image.
Feature #3311, a required feature, provides the first ESCON channel
adapter and feature #3312, an optional feature, provides the second ESCON
channel adapter for increased configurability. The ESCON adapter has an
instantaneous data rate of 17 MB/sec. The Model A50 is capable of
achieving unconstrained data transfer through the ESCON channel.
Performance varies with application and configuration used, but in
general, performance should roughly double what was achieved in the
predecessor Model A00 Controller.
The 3590 Model A50 provides configuration flexibility to tailor a 3590
solution to specific customer requirements. One or two ESCON adapters
can be installed and up to two separate controllers can be placed in some
3590 subsystem solutions. The Model A50 can be featured to present
attached 3590 tape drives as either native 3590 or emulated 3490E
devices.
The Model A50 Controller has remote support capabilities. Features
2710 - 2712 enable quick diagnostics, problem determination and
verification, and a means to upgrade 3590 microcode from remote sites via
modem. IBM supplies the modem to enable remote support.
The "Call Home" function automatically opens a service alert when a
problem occurs with the 3590 Model A60 or A50 Controller. A service
representative can be sent to the installation and status information can
be transmitted to the Support Center for problem evaluation. In
addition, "Call Home" allows these alerts to be sent to a pager service
so that multiple people, including the customer, can be notified. This
function is implemented with no new hardware, utilizing the Remote
Support Features #2710, #2711, or #2712 already installed. The service
representative can activate this function at the installation of the 3590
Model A60 or A50, and service menus can be used to activate or deactivate
this function.
"Call Home" is supported on the 3590 Model A60 and A50 in stand-alone,
Silo, and 3494 solutions. As an added benefit, in the 3494 environment,
you can initiate the "Call Home" process via the 3494 library manager
operator panel.
The 3590 Model A50 is a re-usable storage asset which can be placed in
multiple 3590 storage solutions. The 3590 A14 Frame with an integrated
3590 Model A50 provides a frame attachment of up to four 3590 Model B11
or E11 Tape Drives, with their 10-cartridge Automatic Cartridge Facility
for operator usage. The 3590 A50 can also be integrated in a 3494 Model
L14 or D14 to automate up to four 3590 Model B1A or E1A Tape Drives. A
3494 can be configured with up to sixteen 3590 Model A50 Controllers and
62 3590 Model B1A or E1A Tape Drives.

3590
The Enterprise Tape Drive 3590 attached to the 3590 Model A50
Controller provides attachment of IBM's highest performance, large
capacity tape subsystem, to ESCON channels. It should be the tape drive
of choice in any ESCON environment on ES/3090, ES/9000, or S/390 systems
where a reliable, affordable fast tape data rate or high capacity is
needed. The 3590 offers significant enhancements in performance,
capacity, data integrity, reliability, and availability over IBM 3480,
3490, or 3490E tape drives. The 3590 may also relieve backup time and
space constraints and provide the increased capacity needed to support
today's growing disk backup requirements.
Although the 3590 provides the capability of very high tape
performance, other components of the system may limit the actual
performance achieved.
3590 in a 3494
The 3590 offers the greatest performance and capacity for use in the
IBM 3494. One to four 3590 Model B1A or E1A Tape drives can be installed
in each 3494 Model D14 with a 3590 Model A50 Controller and one or two
Model B1A or E1A Tape Drives can be installed in a 3494 Model L14 with a
3590 A50 Controller. IBM TotalStorage Virtual Tape Server managed 3590s,
3590 Tape Drives, 3590 Model A00, 3590 Model A50, and 3490E drives can
all be intermixed within an Enterprise Tape Library 3494.
Silo Compatible Tape Drive Frame (3590 Model C12 and C14)
The 3590 can be used with StorageTek 4410 and 9310 using 3590 B1A or
E1A Tape Drives, a 3590 C12/C14 Frame, and 3590 A50 Controllers. The
3590 Model C14 Silo Compatible Frame utilizes the "3490E" emulation
provided by the 3590 Model A50 and enables attachment of the 3590 Tape
Drives in a StorageTek automated library to ES/3090, ES/9000, or S/390
systems. This provides the 3590 benefits of increased capacity,
reliability, and performance over 18/36-track technology in an affordable
offering to StorageTek tape library users. The Silo Compatible Frame
Tape Drive Frame 3590 Model C12 or C14 also offers a migration path to an
IBM automation solution consisting of IBM automation, 3590 and 3490 drive
technology, IBM DFSMS(TM), and where appropriate a Virtual Tape Server.
Integration of 3590 Tape Drive technology in StorageTek libraries allows
customers to immediately benefit from 3590 technology, while planning a
migration (at their own pace) to a total IBM solution.

Controller.
The 3590 Model A50 also provides 3490E emulation features that enable
attached 3590 Tape Drives to appear to the host system as "3490E" tape
drives. The 3490E emulation features can be used with 3590 Tape Drives
attached to an A50 controller installed in a 3590 Model A14 stand-alone
solution, both the Model C12 and C14 Silo compatible solutions, or in
rack-mounted subsystem solutions. This feature is not available when the
3590 Model A50 is installed in an Enterprise Tape Library 3494. Either
3590 native mode or 3490E emulation mode should be specified on the Model
A50. Any Model A50 without one of these codes will be assumed to be in
3590 native mode. An MES requesting a different feature will be required
to change the operation mode.
The 3590 Model A50 attaches via ESCON cables to ESCON channels of
ES/3090 and ES/9000 processors or S/390 Servers. One 30.5 meter (100

emulation mode, features #9300 or #4300 must be specified. The 3590 Tape
Drives are added to the host system's I/O configuration as if they were
device type 3590 or 3490E. The 3590 Tape Drives are supported through
the 3590 Model A50 Controller on the following minimum operating systems
levels.
OS/390 (MVS/ESA):
3590 B Model Tape Drive Support
Support for 3590 B Model Tape Drives is provided for the following
software levels. With 3490E emulation, PTFs may be required by some
applications to exploit the full media capacity. The D/T 3590 PSP bucket
should be checked for details on required or recommended maintenance.
MVS/ESA SP Version 5.1, or 5.2 (With JES3: JES3 Version 5.1.1, or
5.1.2 is required) plus SPEs or OS/390 Release 1
DFSMS/MVS Version 1.2.0 or 1.3.0 plus SPEs
EREP Version 3.5 plus PTFs
ADSM/MVS Release 2.1 plus PTFs

DITTO/ESA Release 2
3590 E Model Tape Drive Support
Support for 3590 E Model Tape Drives is provided in PTFs for the
following software levels (earlier levels are not supported, and later
releases will include support). These minimum software levels are
required to support the 3590 E Model Tape Drives in either 3590 native
mode or 3490E emulation mode.
OS/390 Release 1 Version 3, and Release 2 Versions 4, 5, 6, and 7
(OS/390 includes support for JES3) plus SPEs
DFSMS/MVS 1.3.0, 1.4.0, and 1.5.0 plus SPEs (E Model PTFs for DFSMS
are planned to be available on July 23, 1999, for Release 1.4.0; in
August 1999, for Release 1.3.0; in September 1999, for Release 1.5.0.
Check the PSP bucket for availability.)
EREP Version 3.5
ADSM/MVS Release 2.1 plus PTFs
DFSORT R13 and R14 plus PTFs
DITTO/ESA Release 2
Support for the 3590 E Model Tape Drives provides controls to allow
intermixing 3590 E Model and B Model subsystems in an SMS-managed 3494
Tape Library. Allocations provide a desired drive type that is managed
through a data class attribute for the 256-track recording format.
Downward read compatibility of 128-track-recorded tapes on 256-track 3590
E Model Tape Drives is exploited in libraries with both 128-track and
256-track subsystems. Shared common media pools are used for both 3590 B
and E Models. In a 3494 library, the 3590 E Model drives are set up as
type 3590 (not type 3490E). The 3590 E Model software enhancements are
required even if you are not intermixing B Model and E Model subsystems
in the 3494 library.
For 3590 E Model or B Model Tape Drives not inside 3494 libraries
(non-library drives or drives located in silo-compatible frames), the
software support cannot manage allocation among multiple drive models
that use the same emulation type (for example, 3590 E Model and B Model
Tape Drives that are both defined in the I/O configuration as device type
3590). Allocation for different drive models having the same device type
must be managed through local procedures or software products, such as
Basic Tape Library Support (BTLS) or StorageTek's Host Software Component
(HSC). Although the 3590 E Model device support PTFs do not manage
allocation issues for mixed B and E Models outside libraries, this
maintenance should be applied to realize capacity exploitation benefits
with applications such as HSM, OAM Object support, and DFSORT and to
enable EREP reporting by true device type or model.
VM/ESA and VSE/ESA
When attached in 3490E emulation mode, the appropriate release levels
of operating systems and application programs with 3490E device support
are required. No new or enhanced software is required to support the
3590 E Model Tape Drives above and beyond the software required for the
3590 B Models.
The following minimum software levels are required to support 3590 B
Model or E Model Tape Drives in 3590 native mode:
VM/ESA:
VM/ESA Version 2.2
EREP Version 3.5 plus PTFs
ADSM/VM Release 2.1 plus PTFs
DITTO/ESA Release 2
VSE/ESA:
VSE/ESA Version 2.2
EREP Version 3.5 plus PTFs
DITTO/ESA Release 2
Transaction Processing Facility (TPF)
Support for 3590 B Model Tape Drives is provided in the following
minimum software level:
TPF Version 4.1 plus PTFs
Note: OS/390, VM, and VSE system software and service updates are
distributed on 3480/3490 format tape cartridges. In situations where
3590 Tape Drives are sold into new accounts, it will be necessary to
ensure the installation has at least one system-attached 3490 tape drive
to read the system installation tapes.
The following specify code indicates the attached system types. It is
used to determine how microcode updates will be distributed and may be
changed at any time.
#9000 Attached to ES/3090, ES/9000 or S/390 systems
