Packs and disk array enclosures are added when Vblock Systems are built and after they are deployed.

RAID packs

Storage capacity is increased by adding RAID packs. Each pack contains a number of drives of a given

type, speed, and capacity. The number of drives in a pack depends on the RAID level that it supports.

The number and types of RAID packs included in a Vblock System is based on the following:

•

The number of storage pools that are needed.

•

The storage tiers that each pool contains, and the speed and capacity of the drives in each tier.

The following table lists tiers, supported drive types, and supported speeds and capacities.

Note: The speed and capacity of all drives within a given tier in a given pool must be the same.

Tier Drive type Supported speeds and capacities

1 Solid-state Enterprise Flash drives (EFD) (extreme performance) 100 GB 2.5"

200 GB 2.5"

400 GB 2.5"

2 Serial attached SCSI (SAS) (performance) 600 GB 10K RPM 2.5"

900 GB 10K RPM 2.5"

3 Nearline SAS (capacity) 2 TB 7.2K RPM 3.5"

3 TB 7.2K RPM 3.5"

4 TB 7.2K RPM 3.5"

•

The RAID protection level for the tiers in each pool. The following table describes each supported

RAID protection level. The RAID protection level for the different pools vary.

Description

RAID 1/0

•

A set of mirrored drives.

•

Offers the best overall performance of the three supported RAID protection levels.

•

Offers robust protection. Can sustain double-drive failures that are not in the same mirror set.

•

Lowest economy of the three supported RAID levels since usable capacity is only 50% of raw

capacity.
