Server Features Disk Controller The ProLiant DL760 G2 server provides an embedded dual-channel Smart Array 5i Controller. One channel is dedicated to the internal drive bays, and the other channel is connected to the external VHDCI SCSI connector. Refer to Chapter 8 for descriptions of the features and array setup procedures for the controller. The disk controller has 32 MB of read data cache. The Smart Array 5i Controller supports Ultra3 or Ultra320 SCSI hard drives. Ultra3 is a high-performance SCSI technology that offers data transfer speeds of up to 160 MB/sec. It is a term that is synonymous with Ultra160 SCSI and describes any device that combines Ultra2 SCSI with Cyclic Redundancy Check (CRC), domain validation, and double transition clocking. HP Ultra3 universal hot-pluggable hard drives provide this level of performance in addition to compatibility with ProLiant servers, AlphaServers, and StorageWorks Enclosure 4200 solutions. Ultra320 hard drives will run at Ultra3 speeds unless you install an optional Ultra320 Array Controller and the Twisted Pair Cable Array Bypass kit included with the system. NOTE: ProLiant DL760 servers that have been upgraded to ProLiant DL760 Generation 2 servers will run internal hard drives up to Ultra3 speeds regardless of the capability of the drive. Internal Hot-Plug Drive Bays The internal hot-plug drive bays support four 1-inch Ultra3 SCSI hard drives. Drives may be of any storage capacity but must be mounted on HP universal drive carriers (hot-plug drive trays). The internal drive bays also support the StorageWorks Hot-Plug Tape Drive, which takes up two hot-plug drive bays in the media module. Fixed Internal Media Drive Bays The fixed internal media drive bays support two non-hot-plug media drives: • 1.44-MB diskette drive • IDE CD-ROM drive HP ProLiant DL760 Generation 2 Server User Guide 1-13
