IBM TotalStorage DS4300 Turbo, Installation, User'S, And Maintenance Manual

Page: 33 / 220

Note: For the EXP100 only, if there are not any drives inserted in the DS4300
chassis, up to eight EXP100 enclosures can be attached to the DS4300
controller. This is the only case where eight EXP100 drive expansion
enclosures can be attached to the DS4300.
Similarly, up to seven EXP810s with SATA enhanced disk drive modules
(E-DDMs) only can be attached to the DS4300 with no drives inserted in the
DS4300 drive slots. This is the only case where seven EXP810 drive
expansion enclosures can be attached to the DS4300.
Attention: The DS4300/EXP700/EXP710, EXP100 and EXP810 use different
non-interchangeable drive options and CRUs. Please order the correct
options/CRUs for the enclosures in your configuration. Force-fiting insertion of the
incorrect disk drive modules may cause damage to the drive CRUs or the enclosure
chassis slots /backplane.
Notes:
1. The DS4300 single-controller storage subsystem (Model 6LU/6LX) does not
support DS4000 EXP storage expansion enclosures.
2. You do not need to purchase optional DS4000 storage expansion enclosure
entitlements to attach DS4000 EXP drive storage expansion enclosures to
DS4300 Turbo storage subsystems.
3. You can now intermix fibre channel drives (the DS4300 Turbo storage
subsystem, the EXP700 and/or the EXP710 storage expansion enclosures,
and/or the EXP810 with FC enhanced disk drive modules (E-DDMs) storage
expansion enclosures) and SATA drives (the EXP100 storage expansion
enclosures and/or the EXP810 with SATA enhanced disk drive modules
(E-DDMs) storage expansion enclosures) if the following conditions are met:
v You have purchased and installed the FC/SATA Enclosure Intermix premium
feature.
v
You are installing the appropriate version of the controller firmware version
6.19.xx.xx or later on your DS4300 storage subsystems with the appropriate
DS4000 Storage Manager host software version 9.1x installed in the
host/management servers.
v EXP700 enclosures must be upgraded to EXP710 with the DS4000 EXP700
Models 1RU/1RX Switched-ESM Option Upgrade Kit for them to be
intermixed with the EXP810 enclosures. EXP700s can only be intermixed
with EXP100s and EXP710s.
v EXP810 enclosures can be intermixed with EXP710 and EXP100 enclosures
only.
For more information on the cabling firmware requirements and best practices
for intermixing EXP100s, EXP710s, EXP700s and EXP810s in the same
DS4000 storage subsystem configuration, see the IBM TotalStorage DS4000
Fibre Channel and Serial ATA Intermix Premium Feature Installation Overview
that ships with the FC/SATA Enclosure Intermix premium feature. You can also
refer to the IBM TotalStorage DS4000 Hard Drive and Storage Expansion
Enclosure Installation and Migration Guide .
4. Not all combinations of supported drive expansion enclosures are allowed in a
given DS4300 drive loop. Table 9 on page 47 shows the supported drive
expansion enclosure intermix.
