HA SMB Performance Chart

In this article

    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).

    Description

    Usage

    Disk/CSV: Read

    KB/s

    Rate at which data was read from a volume in the Direct Access or Redirected Access mode.

    Disk/CSV: Write

    KB/s

    Rate at which data was written to a volume in the Direct Access or Redirected Access mode.

    Disk/CSV: Total

    KB/s

    Rate at which data was read from and written to a volume in the Direct Access or Redirected Access mode.

    IOPS

    Disk/CSV: Read/sec

    Number

    Rate at which read operations were performed directly on a volume.

    Disk/CSV: Writes/sec

    Number

    Rate at which write operations were performed directly on a volume.

    Disk/CSV: IOPS

    Number

    Rate at which read and write operations were performed directly on a volume.

    Latency

    Disk/CSV: Read Latency

    Millisecond

    Average latency between the time a read request arrived to a file system and the time when it was completed.

    Disk/CSV: Write Latency

    Millisecond

    Average latency between the time a write request arrived to the file system and the time when it was completed.

    Disk/CSV: Latency

    Millisecond

    Average latency required to complete read and write operations on a volume.

    Datastore Queue Length

    Disk/CSV: Read Queue Length

    Number

    Number of read operations queued for a volume.

    Disk/CSV: Write Queue Length

    Number

    Number of write operations queued for a volume.

    Disk/CSV: Queue Length

    Number

    Total number of read and write operations queued for a volume during the sample interval.

    Direct/Redirected Usage

    Disk/CSV: Redirected Bytes/sec

    KB/s

    Average amount of data transferred to or from the disk during write or read operations over the network stack.

    Disk/CSV: Direct Bytes/sec

    KB/s

    Average amount of data transferred to or from the disk during write or read operations.

    Direct/Redirected Latency

    Disk/CSV: Direct Latency

    Millisecond

    Average latency required to complete read and write operations on a volume in the Direct Access mode.

    Disk/CSV: Redirected Latency

    Millisecond

    Average latency required to complete read and write operations on a volume in the Redirected Access mode.

    Direct/Redirected IOPS

    Disk/CSV: Direct IOPS

    Number

    Rate at which read and write operations were performed directly on a disk.

    Disk/CSV: Redirected IOPS

    Number

    Rate at which read and write operations were redirected to a volume through the network.
