IBM TotalStorage DS4300 Fibre Channel Storage Subsystem: Installation, User's, and Maintenance Guide
1. Connect the storage expansion enclosures to drive loop A as follows:
a. Starting with the first storage expansion enclosure, connect a fiber-optic
cable from the In port on the left ESM to the Out port on the left ESM in the
second enclosure.
Leave the Out port on the left ESM in the first enclosure unoccupied.
b. Connect the In port on the left ESM in the second enclosure to the Out port
on the left ESM in the third enclosure.
c. Connect the In port on the left ESM in the third enclosure to port 1A on the
ESM A in the fourth enclosure.
d. Connect port 1B on the ESM A in the fourth enclosure to port 1A on the
ESM A in the fifth enclosure.
e. Connect port 1B on the ESM A in the fifth enclosure to the Out port on the
left ESM in the sixth enclosure.
f. Connect the In port on the left ESM in the sixth enclosure to the Out port on
the left ESM in the seventh enclosure.
2. Connect the storage expansion enclosures to drive loop B as follows:
a. Starting with the first storage expansion enclosure, connect a fiber-optic
cable from the In port on the right ESM to the Out port on the right ESM in
the second enclosure.
b. Connect the In port on the right ESM in the second enclosure to the Out
port on the right ESM in the third enclosure.
c. Connect the In port on the right ESM in the third enclosure to port 1B on the
ESM B in the fourth enclosure.
d. Connect port 1A on the ESM B in the fourth enclosure to port 1B on the
ESM B in the fifth enclosure.
e. Connect port 1A on the ESM B in the fifth enclosure to the Out port on the
right ESM in the sixth enclosure.
f. Connect the In port on the right ESM in the sixth enclosure to the Out port
on the right ESM in the seventh enclosure.
Leave the In port on the right ESM in the last enclosure unoccupied.
3. Connect drive loop A to the DS4300 Storage Subsystem as follows:
v Connect the In port on the left ESM in the seventh enclosure to the Out
(upper) port on drive mini hub 4 on the DS4300.
Leave the In (lower) port on drive mini hub 4 unoccupied.
4. Connect drive loop B to the DS4300 Storage Subsystem as follows:
v Connect the Out port on the right ESM in the first enclosure to the In (lower)
port on drive mini hub 2 on the DS4300.
Leave the Out (upper) port on drive mini hub 2 unoccupied.
You must determine how the host systems will connect to the storage subsystem.
You can connect up to two host systems directly to the storage subsystem, or you
can connect more than two hosts to the fibre channel storage subsystem through
switches. The illustrations in the following sections show common host system
configurations.
Note: The default is one partition. Four-partition and eight-partition configurations
are provided as option upgrades, as is the option of additional attachments
to DS4000 EXP storage expansion enclosures. Contact your IBM resellers or
marketing representatives for more information.
