Tier Four

Tier four data centers

Tier three data centers do not include cooling water supplies. They do, however, include all other features of tier four data centers.

  • Physical Security:24x7x365 onsite monitoring and physical security, including biometric identification mechanisms
  • Power: two or more power supplies from different power providers
  • Onsite generators and reserve fuel supplies
  • Bandwidth: Redundant 1 Gpbs (minimum) connections to the public internet supplied by tier 1 bandwidth vendors
  • Cooling: Redundant cooling (air conditioning) systems
  • Fire Suppression: Redundant automated fire suppression systems
  • Data Replication: SOS stores data redundantly within the center, and/or offsite depending on deployment

How tier four data centers work

Tier 4 data center considered as most robust and less prone to failures. Tier 4 is designed to host mission critical servers and computer systems, with fully redundant subsystems (cooling, power, network links, storage etc) and compartmentalized security zones controlled by biometric access controls methods.
 
Naturally, the simplest is a Tier 1 data center used by small business or shops. Tier 4 composed of multiple active power and cooling distribution paths, has redundant components, and is fault tolerant, providing 99.995% availability.
