Disks are originally configured when a system is set up. In most systems, all disks form one
pool of storage in a managed disk folder. By default, the managed disk folder is named
Assigned. Disks of different classifications, such as 15K, 10K, or FATA are all part of the
managed disk folder.
Storage Center assigns disks of different classifications to one of three tiers. Tier 1 is the
highest performance tier; Tier 3 is the most cost efficient tier.
