C8R09A is the HPE MSA 2040 SAN Controller. It has four host ports and works with 8Gb FC, 16Gb FC, 1GbE iSCSI or 10GbE iSCSI SFPs, so one array can be built for Fibre Channel, iSCSI or a mix of both. The SFP in host port 1 must match host port 2, and the SFP in host port 3 must match host port 4. In a dual controller array, controller B matches controller A. SAN controllers do not ship with SFPs, and each controller takes 2 or 4 of them.
The matching MSA SFP 4-packs are C8R23B (8Gb short wave FC), C8R24B (16Gb short wave FC), C8R25B (10Gb short range iSCSI) and C8S75B (1Gb RJ-45 iSCSI). MSA SFPs are for use only with MSA 2040 SAN controllers, and a 10Gb iSCSI setup can use direct attach cables instead of SFPs. Each controller carries 6 GB of cache, 4 GB of it read/write data cache, with battery-free backup to compact flash. A SAN controller weighs 4.8 lbs.
The LFF and SFF chassis and the two DC-powered chassis take one or two C8R09A controllers. The carrier-grade chassis C8R11A has 24 small form factor bays and two DC power supplies. The Energy Star SAN dual controller arrays, such as the LFF array K2R79A and the SFF array K2R80A, include two of these controllers, with no drives or SFPs. iSCSI needs controller firmware GL101 or later.
The spare numbers are 717870-001 for the MSA 2040 SAN controller, 768079-001 for the compact flash card and 787653-001 for a 2TB MSA dual-port SAS drive with a 12 Gb/s interface, 7,200 RPM, 2.5-inch form factor and 512e format.
