Choose a Colocation Provider with Redundancy and Resiliency in Mind

Your Peace of Mind is Our Priority

Human error, security threats, hardware failures, software issues, third-party problems, power outages, the list of potential causes of downtime in a data centre facility are almost endless.

That’s why any potential colocation provider partner should be able to demonstrate the steps they’ve taken to ensure their facility has sufficient resiliency and redundancy.

In an ideal world, a colocation provider’s architecture design should allow you to benefit from n+1 redundancy. This ensures that all critical infrastructure can be concurrently maintained, and that no single points of failure exist within the environment.

Anything less than that and your own business continuity and disaster recovery plans will need to be rethinked.

However, not all data centres are created equally, and so you should look to partner with a provider that has built the kind of facility that you would build.

Here are a few points to consider when analyzing potential facilities:

• Even the most basic data centres provide a fundamental level of redundancy in the form of uninterruptible power supplies (UPS); dedicated cooling equipment; and a backup generator to keep IT functions online during extended power outages.
• Some build upon this by offering additional redundancies for critical power and cooling components, but still maintain a single path for cooling and power distribution.
• Others go one step further again by offering concurrently maintainable infrastructure by way of a redundant delivery path for power and cooling.
• The very best offer the highest level of redundancy possible: a staggering 99.995% of availability. It does this by introducing the concept of Fault Tolerance to the site’s infrastructure topology.

The classification of your potential colocation partner will inevitably be something you look at. With n+1 redundancies in place and concurrently maintainable critical infrastructure, your IT workloads will be available as and when your business demands.

Your IT services and business operations can be safeguarded even further if the colocation provider also maintains redundant backups of all critical infrastructure. Should a specific component fail, applications and workloads can be restored and your business users will experience little to no service disruption.

Achieving such resiliency and redundancy in-house is virtually impossible for most businesses, and for those organizations who do manage to achieve it, the associated financial investment is extremely high.
