The HA Disk chart displays historical statistics on disk usage for the selected Highly Available SMB share (HA SMB shares can only be created on Cluster Shared Volumes).
The following table provides information on predefined views and counters.
Chart View | Counter | Measurement Unit | Description |
Usage | Disk/CSV2012: Read Bytes/sec | Bps | The rate at which bytes were read from the volume in the direct and redirected access modes. |
Disk/CSV2012: Write Bytes/sec | Bps | The rate at which bytes were written to the volume in the direct and redirected access modes. | |
Disk/CSV2012: Total Bytes/sec | Bps | The rate at which bytes were read from and written to the volume in the direct and redirected access modes. | |
IOPS | Disk/CSV2012: Read/sec | Number | The rate at which reads were performed directly on the volume. |
Disk/CSV2012: Writes/sec | Number | The rate at which writes were performed directly on the volume. | |
Disk/CSV2012: IOPS | Number | The rate at which reads and writes were performed directly on the volume. | |
Latency | Disk/CSV2012: Read Latency | Millisecond | The average latency between the time a read request arrived to the file system and the time when it was completed. |
Disk/CSV2012: Write Latency | Millisecond | The average latency between the time a write request arrived to the file system and the time when it was completed. | |
Disk/CSV2012: Latency | Millisecond | The average latency for completing read and write requests on the volume. | |
Datastore Queue Length | Disk/CSV2012: Read Queue Length | Number | The number of reads outstanding on this volume. |
Disk/CSV2012: Write Queue Length | Number | The number of writes outstanding on this volume. | |
Disk/CSV2012: Queue Length | Number | The total number of read and write requests that were queued for the selected volume during the sample interval. | |
Direct/Redirected Usage | Disk/CSV2012: Redirected Bytes/sec | KBps | The average number of bytes that were transferred to or from the disk during write or read operations via network stack. |
Disk/CSV2012: Direct Bytes/sec | MBps | The average number of bytes transferred to or from the disk during write or read operations. | |
Direct/Redirected Latency | Disk/CSV2012: Direct Latency | Millisecond | The average latency for completing read and write requests on the volume in the direct access mode. |
Disk/CSV2012: Redirected Latency | Millisecond | The average latency for completing read and write requests on the volume in the redirected access mode. | |
Direct/Redirected IOPS | Disk/CSV2012: Direct IOPS | Number | The rate at which reads and writes were performed directly on the disk. |
Disk/CSV2012: Redirected IOPS | Number | The rate at which reads and writes were redirected to the volume through the network. |
