View active volume details

On the Volumes > Active Volumes page for a selected cluster, you can view the following information in the list of active volumes.

Heading Description

ID

ID given when the volume was created.

Account ID

ID of the account assigned to the volume.

Volume Size

Size of the volume from which the snapshot was created.

Used Capacity

Current used capacity of the volume:

  • Green = up to 80%

  • Yellow = above 80%

  • Red = above 95%

Primary Node ID

Primary node for this volume.

Secondary Node ID

List of secondary nodes for this volume. Can be multiple values during transitory states, like change of secondary nodes, but will usually have a single value.

QoS Throttle

Represents the current throttling for the volume.

  • Green = up to 20%

  • Yellow = above 20%

  • Red = above 80%

The value does not include historical throttling on the volume.

Min IOPS

The minimum number of IOPS guaranteed for the volume.

Max IOPS

The maximum number of IOPS allowed for the volume.

Burst IOPS

The maximum number of IOPS allowed over a short period of time.

Average IOPS Last 30 mins

The average number of IOPS executed for all volumes that have this node as their primary.

IOPS are collected over 500 millisecond intervals on the cluster side. SolidFire Active IQ collects these values at 60 second intervals. For each volume, the average IOPS is calculated from the SolidFire Active IQ values collected in the last 30 minutes.

Average Throughput Last 30 mins

The average throughput executed for all volumes that have this node as their primary.

Throughput is collected over 500 millisecond intervals on the cluster side. SolidFire Active IQ collects these values at 60 second intervals. For each volume, the average throughput is calculated from the SolidFire Active IQ values collected in the last 30 minutes.

Average Latency (µs) Last 30 min

The average time in microseconds to complete read and write operations to all volumes that have this node as their primary.

Latency is measured over 500 millisecond intervals on the cluster side. SolidFire Active IQ collects these values at 60 second intervals. For each volume, the average latency is calculated from the SolidFire Active IQ values collected in the last 30 minutes. For more information, see this KB article.

Snapshots

The number of snapshots created for the volume.

Actions

Select the vertical drop-down menu for more details on an individual volume.

View individual volume details

From the Volumes page, you can view more information for an individual volume.

Steps

  1. Select Volumes > Active Volumes.

  2. In the Actions column, select the More information icon for the volume you want and select View Details.

After the page opens for the active volume, you can view recent volume data from the information bar.

Heading Description

Account ID

System-generated ID for the volume.

Volume Size

Total size of the volume.

Used Capacity

Shows how full the volume is.

Average IOPS

Average number of IOPS executed against the volume in the last 30 minutes.

Average Throughput

Average throughput executed against the volume in the last 30 minutes.

Average Latency

The average time, in microseconds, to complete read and write operations to the volume in the last 30 minutes. For more information, see this KB article.

You can view additional details from the Show Volume Details drop-down menu.

Access

The read/write permissions assigned to the volume.

Access Groups

Associated volume access groups.

Non-Zero Blocks

Total number of 4KiB blocks with data after the last round of garbage collection operation has completed.

Zero Blocks

Total number of 4KiB blocks without data after the last round of garbage collection operation has completed.

Snapshot Count

The number of associated snapshots.

Min IOPS

The minimum number of IOPS guaranteed for the volume.

Max IOPS

The maximum number of IOPS allowed for the volume.

Burst IOPS

The maximum number of IOPS allowed over a short period of time.

512e Enabled

Identifies if 512e is enabled on a volume.

QoS Throttle

Represents the current throttling for the volume. The value does not include historical throttling on the volume.

Primary Node ID

Primary node for this volume.

Secondary Node ID

List of secondary nodes for this volume. Can be multiple values during transitory states, like change of secondary nodes, but will usually have a single value.

Volumes Paired

Indicates if a volume has been paired or not.

Create Time

The time the volume creation task was completed.

Block Size

Size of the blocks on the volume.

IQN

The iSCSI Qualified Name (IQN) of the volume.

scsiEUIDeviceID

Globally unique SCSI device identifier for the volume in EUI-64 based 16-byte format.

scsiNAADeviceID

Globally unique SCSI device identifier for the volume in NAA IEEE Registered Extended format.

Attributes

List of Name/Value pairs in JSON object format.

View individual volume performance graphs

From the Volumes page, you can view performance activity for each volume in a graphical format. This information provides real-time statistics for throughput, IOPS, latency, queue depth, average IO size, and capacity for each volume.

Steps

  1. Select Volumes > Active Volumes.

  2. In the Actions column, select the More information icon for the volume you want and select View Details.

    A separate page opens to display an adjustable timeline, which is synced with the performance graphs.

  3. On the left, select a thumbnail graph to view performance graphs in detail. You can view the following graphs:

    • Throughput

    • IOPS

    • Latency

    • Queue Depth

    • Average IO Size

    • Capacity

  4. (Optional) You can export each graph as a CSV file by selecting the export button icon.
