How To Reduce Recovery Data Center Costs
Posted on Tuesday, June 25, 2019
The hybrid cloud operating environment will be with us for some time until regulators and compliance auditors can be convinced that hosted security provisions are at least as safe as on-site provisions. Until then, many organizations will be forced to operate recovery data centers that offer automated failover in the event of a localized outage or disaster taking their primary operations offline.
The biggest problem with these redundant data centers is cost. Instead of equipping one data center, you must now fill two. And if following the OEM’s suggestions, both will be populated with identical hardware, at significant additional cost.
Costs continue to escalate as disk arrays and servers are declared end of service life (EoSL). Instead of having to carry out one hardware refresh, you must now perform two. Then there is the issue of support and maintenance agreements, and the extended, costly implementation period as you attempt to upgrade two data centers in quick succession.
Escaping the identical data center trap
Creating an exact mirror image of your primary data center seems to make sense. In the event of an issue, operations fail over automatically with almost no disruption.
But there’s no reason that the hardware in your recovery data center has to be identical. In fact, because you will only be using the backup for a matter of days, the underlying infrastructure doesn’t have to be cutting edge– you just need your applications and data to be available.
With this in mind, there is no reason to replace your recovery data center every time the primary site is upgraded. As long as you have access to post-warranty support and a reliable supply of spare parts, you can extend the hardware refresh cycle by a further three to five years if required.
Obviously, there may be a slight drop in performance in the event of a failure – but this is to be expected in most cases anyway. And the savings realized by maintaining existing hardware for longer will go a long way to towards mitigating those concerns.

Machine Learning and regulatory compliance are conspiring to make the job of managing storage even harder.
If It Moves, It Will Break
Wear and tear is a very real threat to data center operations– and your uptime.
