2. If more I/O groups are configured, repeat the cabling procedure for the other
I/O groups. Each system can have a maximum of four I/O groups, with two
chains of expansion enclosures attached to each I/O group. Two chains of
expansion enclosures can be attached to each I/O group. On each SAS chain,
the systems can support up to a SAS chain weight of 10.
Combining 2U and 5U expansion enclosures
About this task
As Figure 115 shows, you can combine 2145-24F, 2145-12F, and 2076-92F enclosures
in a SAS chain. The limiting factor is the combined chain weight of the various
components. The maximum SAS chain weight that can be attached to a node SAS
port is 10:
v 2076-92F enclosures have a chain weight of 2.5
v 2145-24F and 2145-12F enclosures have a chain weight of 1.
