FAST VP

 

Fully Automated Storage Tiering for Virtual Pools (FAST VP) enables the system to retain the most frequently accessed or important data on fast, high-performance disks and move the less frequently accessed and less important data to lower-performance, cost-effective disks. FAST VP does the following for pools:

Monitors the usage of the data in a tiered pool. Tiered pools are heterogeneous pools that are configured with multiple classes of disks (SAS Flash 2 plus SAS and/or NL-SAS).

Depending on the tiering policy, uses the monitoring statistics to automatically relocate data chunks, at 256 MB granularity, to other tiers within the pool. For example, the Start High then Auto-Tier policy relocates data to the storage tier that is best suited for that data, based on relative activity.

Performs load balancing across the disks in tiered and non-tiered pools.

FAST VP is an automated feature that optimizes disk utilization. It requires very little manual intervention.

 

 

FAST CACHE

FAST VP

Allows Flash drives to be used to extend the existing caching capacity of the whole storage system

Allows a single LUN to leverage the advantages of multiple drive types through the use of storage pools.

Granularity is 64 KB

Granularity is 1 GB

Data that is accessed frequently is copied from HDDs to Flash drives

Data is moved between different storage tiers based on statistics collected over a period of time

Use when workload changes are unpredictable and very dynamic, and require a quick response time

Use when workload pattern changes are predictable and relatively low.

Constantly promotes frequently accessed HDD data to FAST Cache. There are no relocation cycles.

Data movement occurs in scheduled or manually invoked relocation windows

Calculation to decide which data needs to be promoted to FAST Cache is performed continuously.

Calculation to decide which portion of data need to be moved is performed once every hour.

To configure and use the FAST VP feature, the FAST VP license must be installed on the system. FAST VP can use all supported disk types except for SAS Flash 3 disks. Not all models support FAST VP.
The data relocation performed by FAST VP can help you achieve the following benefits:
 
Increased performance
In some cases, you can double performance throughput by adding less than 10 percent of a pool's total capacity in SAS Flash 2 disks.
 
Reduced Total Cost of Ownership (TCO)
Using a combination of NL-SAS, SAS, and SAS Flash 2 disks instead of all SAS disks enables you to address performance requirements and still reduce the disk count. In some cases, you can achieve up to a two-thirds reduction in disk count by using FAST VP.
