SCSI Storage Enclosure Status
• Transfers/Sec—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—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 %—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
◦ Type or model of the storage enclosure
◦ SCSI protocol is supported by the storage enclosure
◦ Number of drive bays provided by the storage enclosure
◦ Number of SCSI drives installed in the storage enclosure
◦ SCSI adapter attached to the storage enclosure and the port on the adapter
IDE channel
The following information is provided for an IDE channel.
IDE Channel Status
• MBytes/Sec—Average number of megabytes transferred on this IDE channel each second
(the sum of the MBytes/Sec for all ATA disks on this channel)
• Transfers/Sec—Average number of transfers on this IDE channel each second (the sum of the
Transfers/Sec for all ATA disks on this channel)
• Channel Queue—Average number of transfer requests (reads and writes) waiting to be serviced
by ATA disks on the IDE channel
IDE Channel Inventory
Channel Configuration
• IDE controller to which this IDE channel is connected
• Number of ATA disks attached to the channel
