For information on the type 2076 expansion enclosure see the IBM Storwize
V7000 Expansion Enclosure Installation Guide, Machine type 2076 that is shipped
with the enclosure.
v
All type 4939 SAS ports are located at the front of the enclosures. The control
enclosure canisters have one SAS port each and the expansion enclosure
canisters have two ports each (1 and 2). There are no SAS cable connections
required at the rear of the 4939 enclosures.
v There are three different types of SAS cables that might be required to connect
your enclosures.
– To connect a 4939 control enclosure to a 4939 expansion enclosure use the .328
meter HD SAS - HD SAS cable. See Figure 7 on page 16.
– To connect a 4939 control enclosure to a 2076 expansion enclosure use the 6
meter HD SAS - Mini SAS cable. See Figure 8 on page 16.
– To connect a 4939 expansion enclosure to an additional 4939 expansion
enclosure use the .328 meter HD SAS - HD SAS cable. See Figure 7 on page
16.
– To connect a 4939 expansion enclosure to a 2076 expansion enclosure use the
6 meter HD SAS - Mini SAS cable. See Figure 8 on page 16.
– To connect a 2076 expansion enclosure to an additional 2076 expansion
enclosure use the standard mini SAS - Mini SAS that is used normally for
2076 expansion enclosures. See Figure 9 on page 16.
v
On a 4939 expansion enclosure, no cable should be connected between a port on
canister 1 (left) and a port on canister 2 (right) of the same enclosure.
v
On a 2076 expansion enclosure, no cable should be connected between a port on
canister 1 (upper) and a port on canister 2 (lower) of the same enclosure.
v
Connect cables serially between enclosures; do not skip an enclosure.
v
Ensure that cables are installed in a tidy manner to reduce the risk of cable
damage when Flex System V7000 Storage Node replaceable units are removed or
inserted.
Note: You can route the SAS cables alongside the bays in the chassis if needed.
v Arrange your cables to provide access to:
– The USB ports on the node canisters.
– The enclosures themselves. Access is required to the hardware for servicing
and for safely removing and replacing components using two or more people.
v
Review the SAS cable illustrations to help determine the correct cable or cables
for your system.
– Figure 7 on page 16 shows a .328 meter HD SAS - HD SAS cable
– Figure 8 on page 16 shows a 6 meter HD SAS - Mini SAS cable
– Figure 9 on page 16 shows a standard Mini SAS - Mini SAS cable
