SATA Drive Status
• Disk Read/Sec—The average number of reads from the selected SATA drive each second
• Disk Write/Sec—The average number of writes to the selected SATA drive each second
• Disk Read Mbytes/Sec—The average number of Megabytes of data read from the selected
SATA drive each second
• Disk Write Mbytes/Sec—The average number of Megabytes of data written to the selected
SATA drive each second
• Disk Millisec/Read—The average time required to complete a read operation
• Disk Millisec/Write—The average time required to complete a write operation
• Disk Queue Length—The average number of transfer requests (reads and writes) waiting to
be serviced by the SATA drive, including transfers currently being serviced and transfers
waiting for service, regardless of where the request is waiting (drive or controller)
Insight Control performance management uses a set of algorithms to determine the SATA drive
status. The Disk Queue Length is a primary parameter. However, when the value of the Disk Queue
Length exceeds the acceptable value, the Disk Reads/Sec and Writes/Sec are examined to
determine whether read or write operations require most of the drive throughput. When combined
with Disk Millisec/Read or Write, Performance Management can determine if the number of
requests for the drive will exceed the capabilities of the drive.
SATA Drive Inventory
• Drive Information
Displays description of the drive, including size◦
◦ Displays the hard drive model number
◦ Displays the exact size of the drive as seen by the operating system
• Configuration Information
Provides a summary of the drive configuration◦
◦ Displays the name of the Smart Array controller to which it is attached
◦ Displays the location of the hard drive in its enclosure
◦ Displays the array in which the drive is configured
◦ Provides the SATA protocol negotiated for transfers between this drive and the disk
controller
SAS Drives
The following information is provided for a SAS Drive.
SAS Drive Status
• Disk Read/Sec—The average number of reads from the selected SAS drive each second
• Disk Write/Sec—The average number of writes to the selected SAS drive each second
• Disk Read Mbytes/Sec—The average number of Megabytes of data read from the selected
SAS drive each second
• Disk Write Mbytes/Sec—The average number of Megabytes of data written to the selected
SAS drive each second
• Disk Millisecond/Read—The average time required to complete a read operation
