v An optional ServeRAID-MR10i controller provides RAID level 5 support to the
2.5-inch hot-swap drives, and supports an external storage enclosure. A

v An optional IBM SAS HBA Controller adapter enables you to connect external

Ethernet controllers 1 and 2; then, the drives that are connected to the
SAS/SATA controller; then, PCI Express slots 1 and 2.
