I/O adapter features
You must select the I/O adapter features that you want for your storage system.
The I/O adapter features are separated into the following categories:
v 2U I/O enclosure
v Flash RAID adapter pair
v Host adapters
v Host adapters Fibre Channel cables
I/O enclosure
The I/O enclosure holds the I/O adapters and provides connectivity between the
I/O adapters and the storage processors.
The I/O adapters in the I/O enclosures can be either Flash RAID adapters or host
adapters. Each I/O enclosure can support up to two Flash RAID adapters (one
pair), which are imbedded into the PCIe adapter, and two or four host adapters
installed in pairs (not to exceed 16 host adapter ports).
Feature code for 2U I/O enclosure
Use this feature code to identify the 2U I/O enclosure for your storage system.
This I/O enclosure feature includes one 2U I/O enclosure. This feature supports
two or four 16 Gbps 4-port host adapters (installed in pairs).
