The Disk chart displays historical statistics on disk usage for the selected Cluster Shared Volume on Windows Server 2008.
The following table provides information on predefined views and counters.
Chart View | Counter | Measurement Unit | Description |
Datastore Usage | Disk/CSV2008: IO Read Bytes/sec | Bps | Rate at which bytes are transferred from the disk during read operations. |
Disk/CSV2008: IO Write Bytes/sec | Bps | Rate at which bytes are transferred to the disk during write operations. | |
Disk/CSV2008: IO Bytes/sec | Bps | Sum of read and write rates to the datastore. | |
Disk/CSV2008: IO Redirected Read Bytes/sec | Bps | Rate at which bytes are transferred from the disk during read operations in the "redirected access" mode. | |
Disk/CSV2008: IO Redirected Write Bytes/sec | Bps | Rate at which bytes are transferred to the disk during write operations in the "redirected access" mode. | |
Disk/CSV2008: IO Redirected Bytes/sec | Bps | Rate at which bytes are transferred in the "redirected access" mode. | |
Datastore IOPS | Disk/CSV2008: Redirected Read IOPS | Number | Number of new reads that were redirected to the volume through the network since the last time of data collection. |
Disk/CSV2008: Redirected Write IOPS | Number | Number of new writes that were redirected to the volume through the network since the last time of data collection. | |
Disk/CSV2008: Redirected IOPS | Number | Number of new reads and writes that were redirected to the volume through the network since the last time of data collection. | |
Disk/CSV2008: CSV Read IOPS | Number | Number of new reads that were performed directly from the volume since the last time of data collection. | |
Disk/CSV2008: CSV Write IOPS | Number | Number of new writes that were performed directly to the volume since the last time of data collection. | |
Disk/CSV2008: CSV IOPS | Number | Average number of reads and writes per second during the collection interval. |
