Expander Configuration Mode
The C8000XD sled is equipped with a SAS expander to operate the hard-
drives in single port, dual port, or expansion mode. Use mini-SAS x4 cable(s)
to connect a compute sled to your C8000XD sled.
The sled supports the following configuration modes.
• Single port mode
In single port mode, the storage sled supports 12 x 2.5 or 3.5-inch
SAS/SATA/SSD hard-drives from a single cable connection.
The figure below shows a single path connection from a single-HBA/RAID
compute sled to the storage sled’s external mini-SAS A1 and A2
connectors. In this mode, the hard-drives in the storage sled are cascaded
for extended storage capacity.
