The ServeRAID-BR10i controller PCI Express interface is compliant with the PCI Express Specification, revision 1.0a. The controller uses either a standard PCI or low-profile PCI bracket type. The controller SAS interface is compatible with the ANSI Serial Attached SCSI 1.0 specification and the Serial ATA 1.0a specification. The functionality of the ServeRAID-BR10i controller comes from the LSI1068E controller chip. The LSI1068E chip integrates eight high-performance SAS/SATA PHYs. The design of the controller makes it easy to add SAS interfaces to any computer, workstation, or server with a PCI Express bus. The controller provides a 2 Mb x 8-bit flash ROM for storing the BIOS and firmware. The controller provides up to 32 Kb x 8-bit NVSRAM for storing the nonvolatile RAID information when a system failure occurs. The controller provides a 128 Kb x 36-bit pipelined burst static random access memory (PBSRAM) device for storing SAS address port information, which enables connection to more than 128 devices.
