7 QUESTIONS TO ASSESS YOUR UPS’S ABILTY TO HANDLE A POWER CUT
Is your UPS man enough for the job? Can it provide enough energy to down your servers in a managed fashion? It may have been suitable when your system was designed but have you added equipment that would increase the load and, therefore, reduce the time the UPS could run for in a power cut.
Are your batteries more than 3 years old? A battery’s ability to store a charge falls over time. Manufacturers typically state that 3 years is the expected life of a UPS battery. Batteries can be replaced, and Lynx can help with that.
Will your system be brought down in the correct manner / a secure and safe manner? If your systems are to return to normal following an outage, they must be bought down in a managed process. This has to be correctly pre-programmed into the system.
How is an outage communicated to your users? If users can’t see your network because of a power cut at HQ, they may not know the cause. How will they know if the problem is at their end, the server or somewhere in between? You should have a procedure in place to get the message out. This could be via text messages but needs to be initiated and pre-planned.
Will your system automatically restart when the power comes back on? If no one’s around, or available, to restart your system, it could be down for long time. So, ideally, it will be programmed to restart all systems and give users full functionality without human intervention.
If you turned the power off to your servers right now, what would happen? You should carry out a test by switching off the power, ideally during a quiet period to minimise disruption, and seeing what happens. Obviously, you need to warm your users first.
Are you being too optimistic? When designing your UPS system and policy/strategy, you should be a pessimist. If you’re an optimist and think the worst won’t happen and everything will be fine, you could be in for a shock.
How long have your servers and network hardware been continuously running? If equipment is switched off and on for the first time in a long while, it’s quite common to experience failures. You might consider trying this when a failure could be mitigated, rather than it being a bad surprise.
Lynx Networks can help you with all of the above, and we’d love to hear from you.
