• Expansion mode (two zones)
In expansion mode with two zones configuration, the storage sled SAS
expander board supports 12 x 3.5 SAS/SATA hard-drives from a single-
cable connection. The SAS connections are grouped into two zones
(A1/Zone 0 and A2/Zone 1) and each zone allows the host/compute sled to
access a group of hard-drives in the storage sled.
The figure below shows two single-RAID compute sleds connected to the
storage sled’s external mini-SAS A1 and A2 connectors. Each compute sled
can only access the hard-drives in the assigned zone.
