IBM SYSTEM STORAGE EXP3000 - INTEROPERABILITY MATRIX 10-19-2010, Руководство пользователя, Страница: 25 / 64

Dual-ESM configuration
The EXP3000 comes with one ESM. If your RAID controller supports redundant
drive paths (see the documentation that comes with your RAID controller or the
device that contains the RAID controller), you can install a second ESM. See
“Installing an additional ESM” on page 11.

To connect RAID controllers A and B to one EXP3000 that has two ESMs, complete
the following steps:
1. Connect the EXP3000 to RAID controller A:
a. Connect one end of a SAS cable to RAID controller A.
b. Connect the other end of the SAS cable to the In ( ↑ ) SAS connector on the
left ESM in the EXP3000.
2. Connect the EXP3000 to RAID controller B:
a. Connect one end of a SAS cable to RAID controller B.
b. Connect the other end of the SAS cable to the In (

) SAS connector on the
right ESM in the EXP3000.
Dual-ESM configuration with two or more EXP3000s
An ESM in the EXP3000 has two 26-pin mini-SAS connectors. The SAS connectors
are labeled In (
↑
) and Out (
↓
). If your RAID controller supports more than one
EXP3000 per physical port, you can connect two or more EXP3000s by chaining
them together. See the documentation that comes with your RAID controller or the
device that contains the RAID controller for more information.
