3584 High Availability Frame Model HA1

The 3584 High Availability Frame Model HA1 is designed to improve the
performance and availability of the 3584 Tape Library. The Model HA1, in
conjunction with service bay features on the 3584 Models D22 and D52,
provide for the installation of a second library accessor that is
designed to operate simultaneously with the first accessor and service
mount requests in the 3584 Tape Library at the same time. It is designed
to non-disruptively failover to a redundant accessor when any component
of either accessor fails, which helps maintain availability and
relibility. Additionally, this design includes the ability to add one or
more Model D52 or D22 Frames to a 3584 Tape Library that has an attached
Model HA1 with minimal disruption.

Dual active accessor support is provided in a mixed media library.
This includes any combination of 3592 and LTO Ultrium media types.
Advanced Library Management Systems (ALMS) will be required for support
of dual accessors and two or more 3584 frames are required in a high
availability configuration.

A dual accessor library will have two garage areas called service
bays. Service Bay A (the 3584 High Availability Frame Model HA1) is to
left of and adjacent to the L-frame, when facing the front door. Service
Bay B (a modified 3584 Model D22 or D52) is to the right of the last
active frame in the library. The service bays will be regular library
frames but they will not have any drives, power supplies, or node cards.
Storage slots within the service bays will only be used to test service
actions.

The actual performance of the 3584 Tape Library is determined by a
number of factors, such as: accessor capacity, number of library frames,
number of tape drives, location of tape drives and tape cartridges, and
tape cartridge residency.

The Multi-Path Architecture of the UltraScalable Tape Library 3584
provides the capability for sharing of the library robotics. This is
accomplished by partitioning the library into up to 192 multiple logical
libraries (up to the number of drives installed), and providing each
logical library its own separate and distinct drive(s), storage slots,
and control path(s). I/O slots are shared on a first-come-first-served
basis. This type of partitioning allows heterogeneous applications to
share the library robotics independent of each other. Cartridges under
library control are not shared between logical libraries, nor allowed to
be moved between logical libraries. An example of heterogeneous sharing
is a Microsoft Windows 2000 application using the drive and storage slots
of one logical library, while a UNIX application uses the drive and slots
of another logical library.

Logical libraries can also be used for separating Ultrium 1 Tape
Drives and cartridges from Ultrium 2 Tape Drives and cartridges, or 3592
Tape Drives and cartridges, for applications which do not support mixing
the drives in the same logical library.

For enhanced availability you may use Control Path Failover. This
optional feature is designed to provide automatic control path failover
to a preconfigured redundant control path in the event of a loss of a
host adapter or control path drive, without aborting the current job in
progress. Support is provided under AIX and Linux when the IBM device
driver is used.

Two types of path failover capabilities exist: Control Path Failover
(CPF) and Data Path Failover (DPF). Control refers to the command set
that controls the library (the SCSI Medium Changer command set on LUN 1
of the tape drives). Data refers to the command set that carries the
customer data to and from the tape drives (the SCSI-3 Stream Commands
(SSC) device on LUN 0 of the tape drives). Path failover means the same
thing in both: that is, where there is redundancy in the path from the
application to the intended target (the library accessor or the drive
mechanism), the device driver transparently fails over to another path in
response to a break in the active path.

Both types of failover include host-side failover when configured with
multiple host bust adapter (HBA) ports into a switch, but CPF includes
target-side failover through the control paths that are enabled on more
than one tape drive. DPF includes target-side failover for 3592 Tape
Drives only by using the dual-ported interface of the drive.

For enhanced availability you may use CPF. This optional feature is
designed to provide automatic control path failover to a preconfigured
redundant control path in the event of a loss of a host adapter or
control path drive, without aborting the current job in progress. Today
support is provided under AIX, Solaris, and Linux when the IBM device
driver is used. Additional operating systems support will be provided in
the future for installed CPF users.

Data Path Failover and Load Balancing exclusively supports native
Fibre Channel Ultrium 2 Tape Drives and 3592 Tape Drives in the
UltraScalable Tape Library 3584 using the IBM device driver for AIX and
Linux. Data path failover is designed to provide a failover mechanism in
the IBM device driver, which enables you to configure multiple redundant
paths in a SAN environment. In the event of a path or component failure,
the failover mechanism is designed to automatically provide error
recovery to retry the current operation using an alternate, preconfigured
path without aborting the current job in progress. This allows you
flexibility in SAN configuration, availability, and management.

automatically selects a path through the host bus adapter (HBA) that has
the fewest open tape devices, and assigns that path to the application.
This autonomic self-optimizing capability is called Load Balancing. The
dynamic load balancing support is designed to optimize resources for
devices that have physical connections to multiple HBAs in the same
machine. The device driver is designed to dynamically track the usage on
each HBA as applications open and close devices, and balance the number
of applications using each HBA in the machine. This may help optimize
HBA resources and improve overall performance. Further, Data Path
Failover provides autonomic self-healing capabilities similar to Control
Path Failover, with transparent failover to an alternate data path in the
event of a failure in the primary host-side path. Data Path Failover and
Load Balancing for Ultrium 2 Tape Drives attached to Linux or other
operating systems requires an optional feature.

When a 3584 Model HA1 is installed in a 3584 Tape Library, the
following feature numbers must be added to the 3584 Model L22, L32, or
L52 in that library:

1690 - Advanced Library Management System (if not already present)

9003 - Additional Expansion Frame Attachment (at least one additional
frame to serve as Service Bay B)

9040 - High Availability Library

A 3584 Model D22 or D52 must be ordered with the Model HA1 to provide
the second accessor and serve as the Service Bay B for that accessor. It
must be ordered with the following feature:

1440 - Service Bay B Configuration and Second Accessor

When a 3584 Model HA1 is installed in a 3584 Tape Library, the
following feature numbers must be present on one 3584 Model Dxx in that
library (other that the one used as a Service Bay B):

1453 - Frame Control Assembly (or feature number 1452 if the frame is
a Model D32)

1902 - Additional Power Supply (one is required, but it is
recommended that two of these be present for redundancy)

It is also recommended that the Dual AC Power feature (#1901) be
installed on the Model Lxx and Dxx Frames in a 3584 Tape Library
containing a Model HA1.

Each 3584 Tape Library configuration containing a Model HA1 requires a
different set of X-Track cables for the dual accessors in the library,
depending on the total number of frames in that 3584 Tape Library. The
following feature number must be ordered every time the number of
attached frames is changed (either added or removed) in a 3584 Tape
Library that has a Model HA1:

1840 - Change HA X-Track Cable

This feature number will enable the proper X-Track cables to be
shipped based on the presence of feature number 9040 and the quantity of
feature number 9003 on the Model Lxx Frame.

Note: Feature number 1840 is not required with the first installation of
a Model HA1. It is only required when the number of attached frames is
changed after the installation of the Model HA1.

In a 3584 Tape Library without an attached Model HA1 and the total
number of frames in the 3584 library coming from the plant is going to
number 8 to 14 frames (7 to 13 Expansion Frames), the 7-14 Frame X-Track
Cable will be shipped with the library unless the 8-16 Frame X-Track
Cable feature (#9316) is specified on the Model L22 or L52. The 8-16
Frame X-Track Cable feature (#9316) must be specified on the Model L22 or
L52 if there will be a total of 15 or 16 frames (14 or 15 Expansion
Frames) in the 3584 library without a Model HA1.
