EMC VNX FAST VP Definition
FAST VP stands for Fully Automated Storage Tiering for Virtual Pools. It’s a very smart solution for dynamically matching storage requirements with changes in the frequency of data access. FAST VP segregates disk drives into three categories (already explained in EMC VNX – RAID groups vs Storage Pools) called tiers:
Extreme Performance Tier – Flash drives
Performance Tier – 15k and 10k SAS drives
Capacity Tier – Near-line SAS drives (that can be up to 4TB i...

Storage Provisioning
Storage Provisioning
Storage provisioning is the process of assigning storage, usually in the form of server disk drive space, in order to optimize the performance of a storage area network (SAN). Traditionally, this has been done by the SAN administrator, and it can be a tedious process.Storage provisioning is done in steps, which must be followed in a specific order. The storage must be configured for optimum SAN performance. Logical unit numbers (LUNs) must be assigned within the net...

Automated Storage Tiering (AST)
Automated Storage Tiering (AST)
Automated storage tiering (AST) is a storage software management feature that dynamically moves information between different disk types and RAID levels to meet space, performance and cost requirements.
Automated storage tiering features use policies that are set up by storage administrators. For example, a data storage administrator can assign infrequently used data to slower, less-expensive SATA storage but allow it to be automatically moved to h...

Logical Unit Number (LUN)
Logical Unit Number (LUN)
A logical unit number (LUN) is a unique identifier for designating an individual or collection of physical or virtual storage devices that execute input/output (I/O) commands with a host computer, as defined by the Small System Computer Interface (SCSI) standard.
SCSI is a widely implemented I/O interconnect that commonly facilitates data exchange between servers and storage devices through transport protocols such as Internet SCSI (iSCSI) and Fibre Channel (FC)...
