Fully Automated Storage Tiering
EMC Fully Automated Storage Tiering (FAST) provides automated management of
VMAX3 array disk resources on behalf of thin devices. FAST automatically creates
data pools according to each individual disk technology, capacity and RAID type.
FAST moves the most active parts of your workloads (hot data) to high-performance
flash drives and the least-frequently accessed storage (cold data) to lower-cost
drives. FAST:
l
Leverages the best performance and cost characteristics of each different drive
type
l
Reduces acquisition, power, cooling, and footprint costs by delivering higher
performance using fewer drives
l
Factors in RAID protections to ensure write heavy workloads go to RAID 1 and read
heavy workloads go to RAID 6
l
Delivers variable performance levels using Service Levels.
The Service Level is set on the storage group to configure the
performance expectations for the thin devices on the group. FAST
monitors the storage group's performance relative to the Service Level and
automatically provisions the appropriate disk resources to maintain a
consistent performance level.
FAST is entirely automated and requires no user intervention.
The following image shows how FAST moves hot data to high-performance drives, and
cold data to lower-cost drives
