Data center redundancy – What you need to know
What sort of data center redundancy do you have? This question is really two questions:
Do you protect your critical data in multiple data center facilities?
Do the data centers you use deliver a "two of everything" approach to HVAC and power?
You probably only care about data center redundancy if you need high reliability in your key computer systems. High reliability is important if data center downtime is costly to your company. Avoiding data center downtime is usually the driver for data center redundancy. Typical requirements are at least 99.995% uptime, which is 28 minutes of downtime per year or less.
Do you protect your critical data in multiple data center facilities? Companies use multiple data center facilities to prevent downtime associated with the loss of a single data center. This used to mean a primary site that did all the work and a secondary site that could take over if the primary site failed. But newer technologies like virtualization, load balancing and storage replication are allowing clients to instead spread the computing power across multiple sites. This approach can deliver more value from a second (often outsourced) data center.
Do the data centers you use deliver a "two of everything" approach to HVAC and power? Most of the data center ratings systems are concerned with:
Data center power redundancy - two or more utility feeds, generators, UPS systems and outlets to each rack.
Cooling redundancy - multiple air conditioning systems
Multiple telecom entrances
And even multiple entrances to the property.
This "two of everything" approach minimizes downtime associated with both failure and the need for maintenance.
Redundancies are required for the Rated-4 data center rating, and the TIA-942 compliant data center rating.
Data center redundancy is critical if you require high uptime for your systems. Looking for a highly redundant outsource data center solution? Call Lifeline Data Centers at 317.423.2591
