SCSI storage enclosure
The following information is provided for a SCSI storage enclosure.
SCSI Storage Enclosure Status
•Transfers/Sec—The average number of transfers on this SCSI bus each second (the sum of the Disk Transfers/Sec for all hard drives on this bus).
•MBytes/Sec—The average number of megabytes transferred on this SCSI bus each second (the sum of the Disk MBytes/Sec for all SCSI drives on this bus).
•SCSI Utilization %—The average SCSI utilization for this SCSI bus, which is primarily dependent on the MBytes/Sec, and the SCSI protocol negotiated between the controller and each drive on the bus. The negotiated SCSI protocol is reported in the hard drive inventory. The valid SCSI protocols include:
•SCSI-1—5 MB/s with 8-bit transfers at 5 MHz (5,000,000 bytes/s)
•Fast SCSI-2—10 MB/s with 8-bit transfers at 10 MHz (10,000,000 bytes/s)
•Fast-Wide SCSI-2—20 MB/s with 16-bit transfers at 10 MHz
•Ultra SCSI-3—20 MB/s with 8-bit transfers at 20 MHz
•Wide-Ultra SCSI-3—40 MB/s with 16-bit transfers at 20 MHz
•Wide Ultra2 SCSI—80 MB/s with 16-bit transfers at 40 MHz
•Wide Ultra3 SCSI—160 MB/s with 16-bit transfers at 80 MHz
•Ultra320 SCSI—320 MB/s with 16-bit transfers at 160 MHz
SCSI storage enclosure performance is determined by the SCSI Utilization %.
SCSI Storage Enclosure Inventory
•Enclosure Configuration
•The type or model of the storage enclosure
•Which SCSI protocol is supported by the storage enclosure
•The number of drive bays provided by the storage enclosure
•The number of SCSI drives installed in the storage enclosure
•The SCSI adapter attached to the storage enclosure and the port on the adapter
