VCE Vblock™ Systems Series 700 Architecture Overview
Scaling up storage resources
To scale up storage resources, you can add RAID packs, engines, cache, and DAE packs. Optionally,
expansion cabinets can be added with additional resources.
RAID packs
Storage capacity can be 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 upon the RAID level that it supports.
The number and types of RAID packs to include in a Vblock system is based upon 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.
