To access pool details, click Storage Systems. Then click a storage system to view all resources. Click Pools and then click a pool tile.
Note: An external pool cannot be edited or deleted.
Note: Some values cannot be displayed in an environment without an SVP. In that case, a hyphen displays.
In the pool details window, you can:
- View the attributes of the pool.
- View a graph of utilization and thresholds.
- If the pool is based on a parity group using accelerated compression ("FMD DC2 Compression"), you can also view compression details, including expansion ratio and compression ratio.
- For a tiered pool, view the following tier information:
Pool tier usage for the pools supported on the storage system. Ops Center Administrator supports Bronze, Silver, Gold, and Platinum or Diamond tiers. For each tier, you can view statistics for buffer space, tier relocation and performance utilization. Click the pencil icon to update the storage from tier that has been allocated to the pool.
- View volumes carved from the pool and perform procedures on them. Available procedures include deletion, updating, attaching and detaching to and from servers, protecting, unprotecting, and restoring. Click a volume to open the detail window for the volume.
The Provisioning Status can be any of the following:
- Attached: the volume is attached to a server.
- Unattached: the volume is not attached to a server.
- Unmanaged: the volume has only a LUN path associated. For example, a volume might be attached to a server that is not known to Ops Center Administrator.
The Data Protection can be any of the following:
- Protected: the volume is protected.
- Unprotected: the volume is not protected.
- Secondary: the volume is a snapshot or clone of another volume.
- If the volume uses compression or deduplication and compression, you can view the compression ratio and deduplication ratio.
- Delete the pool.
- Edit the pool configuration by clicking the pencil icon to open the Update Storage Pool window.
- Edit a tiered pool configuration by clicking Update Tiering Settings to open the Update Tiering Settings window.
- After a pool is created, you can edit the pool label or expand the pool. Basic and advanced options, like those for pool creation, are available for pool expansion. The basic option includes choices for a new/expanded pool size based on the current set of parity groups in the pool. You can choose to expand an existing tier in the pool or add a new tier to the pool. If you add a tier to a thin pool, it will be expanded and converted into a tiered pool. Using the advanced option enables you to add more parity groups to the pool and increase capacity. Note: To expand an HDP pool, you must add a parity group of the same RAID layout, the same disk type, the same RAID level, and the same disk speed.
Click Submit to update the window and start a job that will update the pool.
If the pool contains capacity that has had compression technology applied, you can view the following:
- Total Efficiency:
- The ratio of the total saving effect achieved by accelerated compression, capacity saving (compression and deduplication), snapshot, and Hitachi Dynamic Provisioning. Shows for the following storage systems:
- VSP E series
- VSP G/F350, G/F370, G/F700, G/F900 with firmware version 88-03-0x or later
- Compression and Deduplication metrics:
- Software Saving: The capacity reduction ratio before and after capacity saving.
- Software Compression: The capacity compression ratio before and after capacity saving.
- Software Deduplication: The capacity deduplication ratio before and after capacity saving.
- Software Pattern Matching: The capacity reduction ratio before and after capacity saving pattern matching.
- FMD Compression:
- FMD Saving: The capacity reduction ratio before and after capacity saving.
- FMD Compression: The capacity compression ratio before and after accelerated compression.
- FMD Pattern Matching: The capacity reduction ratio before and after accelerated compression pattern matching.
- Calculation End Time: The end date and time for the calculation. The date and time are displayed in UTC.
- Calculation Start Time: The start date and time for the calculation. The date and time are displayed in UTC.
- Provisioning Efficiency: The efficiency ratio achieved by Dynamic Provisioning.
- Capacity Efficiency:
- Capacity efficiency is the ratio of Thin Free plus Thin Used to the physical used capacity. Capacity efficiency is only calculated for volumes on Thin, Tiered, and Snap pools. Shows for the following storage systems:
- VSP E series
- VSP G/F350, G/F370, G/F700, G/F900 with firmware version 88-03-0x or later
- Compression and Deduplication metrics:
- Software Saving: The capacity reduction ratio before and after capacity saving.
- Software Compression: The capacity compression ratio before and after capacity saving.
- Software Deduplication: The capacity deduplication ratio before and after capacity saving.
- Software Pattern Matching: The capacity reduction ratio before and after capacity saving pattern matching.
- FMD Compression:
- FMD Saving: The capacity reduction ratio before and after capacity saving.
- FMD Compression: The capacity compression ratio before and after accelerated compression.
- FMD Pattern Matching: The capacity reduction ratio before and after accelerated compression pattern matching.
- Calculation End Time: The end date and time for the calculation. The date and time are displayed in UTC.
- Calculation Start Time: The start date and time for the calculation. The date and time are displayed in UTC.
- Provisioning Efficiency: The efficiency ratio achieved by Dynamic Provisioning.
- Data Reduction:
- The ratio of logical used capacity to the physical used capacity, for all compression and deduplication technologies. Note: The value displayed as the capacity of data after reduction includes the size of meta-data and garbage data generated by the storage system in addition to user data. For this reason, the value might be greater temporarily than the capacity of data before reduction.
The following actions on volumes are available on this window:
- Click the plus sign (+) to add volumes on the Create Volumes window.
- Click a volume to view details and attach, update or delete the volume.
- Select a volume, then click Edit to update the volume by editing the name or updating the Capacity Saving setting and command device settings. You can also expand the capacity.
