When considering infrastructure changes such as cloud or on premise servers, one aspect that’s often overlooked is the cost of possible downtime caused by hardware failure – most common is RAID failure.
If you use a highly transactional database (a CRM or stock management system for example) and your physical server has a failure, then that downtime will cost the business whilst you wait for your replacement part or installation.
Single disk failure could put your entire RAID array in danger. If your server is relatively new, and you chose to take a suitable warranty or support agreement from the manufacturer, providing you have no further hardware failures, you’ll probably be okay to carry on working whilst your disk is being rebuilt.
However, there are more issues if you have older tin or tin that’s out of warranty. If a disk fails, you will have to swap it for an identical disk. Finding an identical disk and replacing your old one could take time putting extra load on the other disks. This often causes a domino effect putting your entire RAID in danger of failing. Companies sometimes spend weeks trying to rebuild their RAID array.
Downtime can be crippling
Being out of action for weeks can be financially crippling for a business. Disk failure and subsequent RAID failure can happen at any time and is a risk to your business continuity.
We’ve known companies come to us after being told that replacement parts could take weeks to arrive. Fortunately, we’re able to migrate servers into the Cloud and get organisations back up and running within a few hours.
We appreciate that hindsight is a wonderful thing, but the Cloud has no single point of failure. This means that if a company’s infrastructure was already in the Cloud, and the datacentre suffered hardware failure, their VMs would have seamlessly migrated to a different physical server in the datacentre whilst the hardware was repaired or replaced.
It’s not just RAID array failure that can be a problem. Mother board failures and RAM issues can take days to resolve too. Replacing your entire server could take a week or more to sort as well.
Could your business cope?
There are solutions to the above issues – don’t panic!
A lot of companies have failover kit that they use in situations like the above. The downside to this is that it’s expensive because your upfront costs are doubled (you’ll be buying two servers). It’s inefficient as well because you’ll have idle servers.
You could have your failover kit in the Cloud. This would involve paying a small monthly reservation fee ready for when disaster strikes. You could replicate onsite tin into a datacentre so that if there’s an on-premise failure, the Cloud would take over and your company could carry on working.
