dual redundant RAID controllers and power supplies, and supports storage
capacity expansion using external DS4000 EXP storage expansion
enclosures.
Note: This upgrade does not come with any entitlements to attach DS4000
EXP storage expansion enclosures. Once the DS4300 storage
subsystem is upgraded, you can purchase up to three DS4000 EXP
storage expansion enclosure attachment entitlements to provide
additional storage capacity beyond the DS4300 internal drive lots.
IBM DS4300 Model 6LU/6LX Turbo Upgrade (IBM P/N 24P8964)
Use this product to upgrade to the DS4300 Turbo option, which provides
dual redundant RAID controllers and power supplies in addition to the
following features:
v RAID controllers with 1 GB of memory, instead of the standard 256-MB
memory
v Support for IBM DS4000 Storage Manager and DS4300 controller
firmware version 6.12.xx.xx and higher.
v Ability to connect up to seven 14-drive DS4000 EXP storage expansion
enclosures
Note: If there are any DS4000 EXP 16-drive storage expansion
enclosures (such as the EXP810) in the DS4300 drive loop, the
maximum number of storage expansion enclosures that can be
attached to the DS4300 storage subsystem is reduced to 6
instead of 7. See "Connecting storage expansion enclosures to
the DS4300" on page 45 for more information.
v Entitlement for eight partitions using the Storage Partitioning premium
feature
The DS4300 dual-controller storage subsystem (Model 60U/60X) includes two RAID
controllers, two power supplies, and two cooling units and provides dual, redundant
controllers, redundant cooling, redundant power, and battery backup of the RAID
controller cache.
This DS4300 storage subsystem is designed to provide maximum host- and drive-
side redundancy. Each RAID controller supports direct attachment of up to two
hosts containing two fibre channel host adapters.
Note: You must make Fibre Channel connections to both DS4300 controllers to
ensure full host-side redundancy.
The latest versions of the IBM DS4000 host software and the DS4000 controller
firmware on the DS4000 System Storage Support Web site that support the
DS4300 dual-controller Model 60U/60X storage subsystem are version 9 and
6.19.xx.xx, respectively.
Utilizing these features with the 14 internal disk drive expansion enclosures
(EXP700/EXP710/EXP100), up to 112 disk drives can be attached to the DS4300
with individual fibre channel disk drive module (DDM) capacities ranging from 36.4
to 300 GB or individual SATA disk drive module (DDM) capacities ranging from 250
GB to 400 GB. In addition, the DS4300 can be attached to six 16 internal disk drive
expansion enclosures (EXP810), allowing a max of 110 disk drives can be attached
