EMC Unity – FAST VP

EMC Unity Fully Automated Storage Tiering for Virtual Pools (FAST VP) monitors the data access patterns within Pools on the system, and dynamically matches the performance requirements of the data with drives that provide that level of performance. FAST VP has three categories, called tiers, which it segregates drive drives into. These tiers are:

  • Extreme Performance Tier – Comprised of Flash drives
  • Performance Tier – Comprised of Serial Attached SCSI (SAS) drives
  • Capacity Tier – Comprised of Near-Line SAS (NL-SAS) drives

FAST VP helps to reduce the Total Cost of Ownership (TCO) by maintaining performance while efficiently utilizing the configuration of a Pool. Instead of creating a Pool with one type of drive, mixing Flash, SAS, and NL-SAS drives can help reduce the cost of a configuration by reducing drive counts and leveraging larger capacity drives. Data requiring the highest level of performance is tiered to Flash, while data with less activity resides on SAS or NL-SAS drives.

The FAST VP configuration and setting as below. By default FAST VP is activated if the license is enabled on Unity, you can modify the relocation rate and relocation schedule on Storage Configuriaon Settings.
