ATA disk array 6
ATA disk array
The following information is provided for an ATA disk array.
ATA Disk Array Status
• Reads/Sec—The number of reads from this ATA disk array each second
• Writes/Sec—The number of writes to this ATA disk array each second
• Read MBytes/Sec—The average number of megabytes read from the ATA disk array each second
• Write MBytes/Sec—The average number of megabytes written to the ATA disk array each second
• Millisec/Read—The average time for each read to complete
• Millisec/Write—The average time for each write to complete
• Queue Length—The average number of concurrent requests between the server and this ATA disk array,
including transfers currently being serviced and transfers waiting for service, regardless of where the
request is waiting (disk or IDE controller)
ATA disk array performance is not evaluated because the performance of an array is determined by the
performance of the disks in the array.

• Array Configuration
• Displays the total capacity of the disk array
• Displays where the disk array is defined (which IDE controller)
• Displays the RAID level and striping factor (if applicable) for the array
