HA SMB Performance Chart

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).

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

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.

I want to report a typo

There is a misspelling right here:

 

I want to let the Veeam Documentation Team know about that.
