Instruction Manual

Drive Array Status
• Reads/Sec—The number of reads from each drive in the drive array each second
• Writes/Sec—The number of writes to each drive in the drive array each second
• Read MBytes/Sec—The average number of megabytes read from each drive in the drive array each
second
• Write MBytes/Sec—The average number of megabytes written to each drive in the drive 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 each drive in the
drive array, including transfers currently being serviced and transfers waiting for service, regardless of
where the request is waiting (drive or controller)
Drive Array Inventory
• Array Configuration—Displays on which Smart controller the drive array is defined and the number of
array logical drives implemented on the array
• Hard Drives—Lists the SCSI drives constituting the disk array
• Spare Drives—Lists the SCSI drives designated as spares
Logical drive
The following information is provided for a logical drive.
Logical Drive Status
• Reads/Sec—The number of reads from this logical drive each second
• Writes/Sec—The number of writes to this logical drive each second
• Read MBytes/Sec—The number of megabytes read from the logical drive each second
• Write MBytes/Sec—The number of megabytes written to the logical drive 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 logical drive,
including transfers currently being serviced and transfers waiting for service, regardless of where the
request is waiting (disk or controller)
Logical Drive Inventory
Logical Drive Configuration
• The controller on which the logical drive is defined
• The array label (such as A, B, or C) as shown by the Array Configuration Utility (ACU)
• The logical drive number as assigned by the ACU and the physical disk mapping
• Logical drive size in megabytes
• The RAID level for this logical drive
• The logical drive striping factor
• Whether caching is enabled for this logical drive
