Disk Management for Datastor
About disk management
You can use disk management to allocate dedicated disk space for the datastor service, which increases the data storage that BIG-IP® Application Acceleration Manager™ (AAM™) uses for deduplication. Additional disk space is available in the following deployments.
- If you are installing BIG-IP AAM Virtual Edition, you can select an extra disk deployment configuration.
- Selected higher-end BIG-IP AAM platforms support the use of solid-state drives (SSDs) that come in a dual-disk drive sled and are installed along with hard disk drives.
Task summary
Perform these tasks to configure disk management for Application Acceleration Manager™ (AAM™).
Task list
Provisioning extra VE disk for datastor
Before beginning this procedure, you must have licensed and configured BIG-IP®
Application Acceleration Manager™ (AAM™) Virtual
Edition (VE).
If you selected one of the extra disk options when you configured BIG-IP AAM VE,
you must manually allocate the disk space to the datastor service, after you delete the
datastor application volume from the primary disk. Datastor cannot span the primary disk
and the extra disk.
The datastor is now allocated to the extra disk. You can verify the result by
checking the Disk Management screen.
Provisioning solid-state drives for datastor
Before beginning this procedure, you must have licensed Application
Acceleration Manager™ (AAM™).
By default, datastor, which is the data storage used for optimization,
is provisioned on the primary hard disk drive (HDD). To use solid-state drives (SSDs) on
BIG-IP® AAM, you must manually allocate the disk space on each
SSD to the datastor service. If you install SSDs after you have provisioned AAM, you
must first de-provision AAM, and then delete the datastor application volume from the
primary disk, before you assign the datastor service to the SSD volume.
The datastor service is now allocated to the SSDs. The datastor volume spans the
installed SSDs. You can verify the result by checking the Disk Management screen. The
logical view displays the datastor allocation for each disk.
Monitoring SSD usage
If you are using solid-state drives (SSDs) for datastor, you can view the SSD allocation
and monitor the SSD lifespan.
- On the Main tab under System, click Disk Management.
-
Use the Disk Management screen to view details about the SSDs, including the following.
- To view the general properties of a disk, in the Logical View area, click the disk label.
- In the Physical View area, note which bays contain the SSDs.
- In the Data Disks area, view the Media Wearout Indicator to monitor disk usage.
