Data center
standards
SatDc follow international standards for all Data Center
that we construct.
Uptime institute recommendations and ANSI/TIA-942 guild lines are the widely used standards across the globe.
The are four categories when it comes to the Tier rated classification. All these ratings has been arrived to understand what level of redundancy is maintained in the Data Centre when you measure the guaranteed uptime.
A Tier1 data center is built with very minimal components without any redundancy. It will have only one cooling machine and one single source UPS power. We don’t recommend our clients to go for a Tier 1 Data Center since it has no guarantee when it comes to availability.
This Data Center will be having N+1 Redundancy on Cooling and UPS power, But these devices will be connected to single utility power and not concurrently maintainable. If one system fails, the redundant system will take care of the needs, but if the panel fails or the cable cuts then the DC goes down.
This is an improved design with concurrently maintainable infrastructure. This data centre will have power and cooling redundancy, a dedicated cable path for each component, independent incoming and outgoing panel etc. This is concurrently maintainable. Each component can be repaired, upgraded, or removed without disrupting the running IT equipment.
This is designed with a very high availability model. This Data Center will be connected to two different power service providers. The entire system will be on N+N redundancy; The construction cost will be high since it requires separate dedicated rooms for all redundant components. Two electrical rooms, Two UPS rooms, Two battery rooms etc. This data centre is considered “fault-tolerant”. Any unplanned maintenance, unexpected fire instance, any power outages will not affect the data center day to day operation.
Tier 4 design gives 99.995% Guaranteed availability.
