Optimize TPV/FTV Capacity
Overview
This function optimizes capacity for a TPV or an FTV.
Volume Requirements for Optimizing Capacity:
Volumes without the "Readying" state, the "Not Ready" state, or the "Broken" state
Volumes that are not undergoing the capacity optimization or volumes that are not reserved for optimization
Volumes that are not ODX Buffer volumes
Volumes that are not undergoing RAID migration
Volumes that are not undergoing TPV balancing
FTVs that are not undergoing FTRP balancing
Allocation method is not "Thick"
Do not execute capacity optimization for NAS user volumes, NAS backup volumes, and NAS system volumes.
- The Thin Provisioning function and the Flexible Tier (Automated Storage Tiering) function can be effectively used by using the [Optimize TPV/FTV Capacity] function when system configurations or system environment modifications are performed. Examples of when to use the [Optimize TPV/FTV Capacity] function are as follows:
After the initialization of the OS or the file system (such as writing 0 data to all the volumes) is complete
After RAID migration from "Standard" to "TPV" is complete
After RAID migration from "Standard" to "FTV" is complete
The progress of the optimizing can be checked with "Optimizing Capacity Progress" on the [Volume Detail] screen (Basic). Refer to the [Volume (Basic Information)] function for details.
The optimizing capacity can be reserved for the source volume of the RAID migration. Refer to the [Start RAID Migration] function for details.
