The IBM® SAN Volume Controller (SVC) software-defined storage is based on the IBM
System x3550 M3 hardware platform. The original SVC design provides high performance
and scalability with a single host bus adapter with four-port 8 Gbps Fibre Channel I/O.
Now, you can add a four-port 8 Gbps Fibre Channel host bus adapter (HBA) to the controller
(feature code AHA7). It is commonly referred to as the second HBA.
This feature is supported on machine type 2145, Model CG8, and it is mutually exclusive of
other supported features, such as internal solid-state drives (feature code 4500) and 10 Gbps
iSCSI-FCoE (feature code 4700). The second HBA option was introduced with the Fibre
Channel port masking capability in SVC Version 188.8.131.52.
In this IBM Redpaper™ publication, we describe how the second HBA is configured on the 2145-CG8 and how to
use Fibre Channel port masking.
