Storage Profile

Select the Storage Profile you would like this volume to use.

Standard Profiles

Recommended (All Tiers)

The Recommended Storage Profile is available only when Data Progression is licensed. Cost and performance are optimized when all volumes use the Recommended Storage Profile. The Recommended profile allows automatic data progression between and across all storage tiers based on data type and usage.

Because SSDs are automatically assigned to Storage Tier 1, profiles that include Storage Tier 1 allow volumes to use SSD storage. If you have volumes that contain data that is not accessed frequently, and do not require the performance of Tier 1 SSDs, use a Medium or Low Priority Profile or create and apply a new profile that does not include Storage Tier 1.

High Priority (Tier 1)

The High Priority Storage Profile provides the highest performance by storing data on Tier 1. It is efficient in terms of using RAID 5 or 6, but it uses more expensive media to store the data. A volume created using the High Priority profile stores written data on Tier 1, RAID 10 (mirrored drives). Replay data is stored on Tier 1, RAID 5/RAID 6. Storage Center does not migrate data to lower storage tiers unless Tier 1 storage becomes full.

Medium Priority (Tier 2)

The Medium Priority Storage Profile provides a balance between performance and cost efficiency. A volume created using the Medium Priority profile stores written data on RAID 10, Tier 2. Replay data is stored on RAID 5/RAID 6, Tier 2. Storage Center does not migrate data to other storage tiers unless Tier 2 storage becomes full.

Low Priority (Tier 3)

The Low Priority profile provides the most-cost efficient storage. Creating a volume using the Low Priority profile stores written data on RAID 10, Tier 3. Replay data is stored on RAID 5/6, Tier 3. Storage Center does not migrate data to higher tiers of storage unless Tier 3 storage becomes full.

Flash Only Profiles

Low Priority (Tier 3)

The Low Priority profile provides the most-cost efficient storage. Creating a volume using the Low Priority profile stores written data on RAID 10, Tier 3. Replay data is stored on RAID 5/6, Tier 3. Storage Center does not migrate data to higher tiers of storage unless Tier 3 storage becomes full.

Flash Optimized with Progression (Tier 1 to All Tiers)

The Flash Optimized with Progression Storage Profile provides the most efficient storage for an enclosure containing both read-intensive and write-intensive SSDs. The Flash Optimized with Progression profile ensures that all write operations are carried out on write-intensive Tier 1 drives, and read operations are directed to read-intensive Tier 2 drives. If Tier 1 fills to within 95% of capacity, System Manager creates a space management Replay and moves it immediately to Tier 2 to free up space on Tier 1.

Write Intensive (Tier 1)

The Write Intensive Storage Profile directs all initial writes to write-intensive SSDs on Tier 1 (RAID 10). This data does not progress to any other Tier, but remains on Tier 1. This profile is useful for storing T-Logs and temporary database files.

Flash Only with Progression (Tier 1 to Tier 2)

The Flash Only with Progression Storage Profile performs initial writes on high-performance Tier 1 drives. Less active data progresses to Tier 2, but remains on SSDs. This profile is useful for storing volumes with data that requires optimal read performance, such as golden images, linked clones, and some databases.

Low Priority with Progression (Tier 3 to Tier 2)

The Low Priority with Progression Storage Profile directs initial writes to less expensive Tier 3 (RAID 10) drives, and then allows frequently accessed data to progress to Tier 2. This profile is useful for migrating large amounts of data to Storage Center without overloading Tier 1 SSDs.
