IBM Enterprise Storage Server 2105 E10, Introduction And Planning Manual

v
You must fill out custom configuration work sheets, using a modified version of a
Define Disk Groups work sheet that closely matches the storage capacity being
installed with the Model 100 expansion enclosures and 7133 drawers. The 7133
drawer will be configured as 2 disk groups. The disk groups can be either RAID
5 arrays or non RAID disks. Logical configuration of the 7133 drawers is only
supported via ESS Specialist. See the
IBM Enterprise Storage Server
Configuration Planner .
v
You cannot attach the Model 100 to an ESS model that already has an ESS
expansion enclosure (FC 2100).
v
You reserved the necessary device loops in the ESS with FC 9904
With two FC 9904 (four reserve loops), you can attach up to a maximum of
twelve 7133 Model 020 or Model D40 drawers. With one FC 9904 (two reserve
loops), you can attach up to the maximum of six 7133 Model 020 or Model D40
drawers.
v
The 7133 drawers can only be installed in a new Model 100 (FC 1121 and FC
1122). The drawers must meet the following requirements:
– When attached to an ESS, up to six 7133 drawers can be installed in a Model
100 rack. A maximum of two Model 100s can be attached to an ESS.
– Only 7133 Model 020 and 7133 Model D40 drawers can be attached to the
ESS.
– You cannot attach drawers that have less than 16 DDMs to the ESS. All the
DDMs must be the same capacity. The ESS cannot support mixed DDMs on
the same loop.
– Any 7133 drawers you install must meet the 7133 drawer compatibility
requirements above.
– You need to migrate or remove all data on 7133 drawers and disband the
ranks/arrays before installing the 7133 drawers in the model 100.
See “Appendix C. Adding and Removing Drawers and Racks” on page 91 for more
information on attaching 7133 drawers and racks to the ESS.
Connection hardware
This section includes the feature codes for:
v
SCSI host cables
v
Fibre-channel cables
v
ESCON host cables
v
Remote power-control attachment cables
SCSI host cables
You need to order cables for each host adapter. Each host adapter provides two
host connections (ports). Each host connection has a terminator; the connection to
the ESS must be at the end of the SCSI bus.
For each SCSI host adapter (FC 3002), order two SCSI host cables:
9701 Ultra-SCSI cable (10 m for UNIX and Windows NT)
9702 Ultra-SCSI cable (20 m for UNIX and Windows NT)
9703 SCSI-2 fast and wide cable (10 m for IBM RS/6000 MCA adapter)
9704 SCSI-2 fast and wide cable (20 m for IBM RS/6000 MCA adapter)
9705 SCSI-2 fast and wide cable (10 m for IBM AS/400)
