DATA CENTER

In Plain Terms

Tier III Data Center and Tier IV infrastructure: Multiple active power and cooling distribution paths, redundant components and fault tolerance.

Unlike a Tier III data center, both distribution paths are active in Tier IV data centers. Because of this fault tolerant functionality, a Tier IV data center provides the capacity to conduct any planned activity without disruption.

One unplanned failure can be sustained with no impact as well. Active distribution paths are in place to support this protection in a System+System configuration (S+S).

For businesses with IT requirements for reliability, availability and serviceability, Tier4 site infrastructures are ideal. Such IT concepts typically entail CPU clustering, RAID DASD and redundant communications.
