There is no better way to bring home this book s mission statement that achieving true high availability requires more than just installing failover management software than to discuss electricity and electrical dependencies. A system that is functioning perfectly will, of course, stop instantly when its electrical supply is cut off. If two systems are connected together in a highavailability pair, and their electricity is cut off, they will both stop working. By providing electricity through separate paths, their power source, and therefore the systems, becomes more reliable. The farther upstream the power source paths can be separated, the more reliable the power supply gets. Plugging both systems in an HA pair into the same power strip is obviously silly, especially if the power strip has a single on/off switch on it. Running both systems through the same circuit breaker is almost as silly, but much

more common, probably because it s a little harder to see which power outlets are on the same circuit. The extreme at the other end is to obtain power from two different power grids or power companies. While this will provide system protection against some major outages, it can be prohibitively expensive and may introduce problems with grounding or other electrical issues.

One customer I had was very concerned about power outages. He went to the extreme measure of running power to the building from two separate power companies. The problem was that they chose to run both lines into the building through the same power pole in the parking lot in front of the building. When a car knocked down that pole, power from both companies was interrupted until the pole could be re-erected and the lines rerun. Evan

Another way to defend your operations against power interruptions is through the use of a so-called uninterruptible power supply (UPS). The uninterruptible part is pure marketing. UPSs are nothing more than battery backups that will continue to provide power for a limited amount of time after electricity fails. But, like any other battery, they will cease to function after their power has been drained. The duration of the power protection is determined by the capacity of the battery unit and the amount of power being drawn. More capacity and less power drawn means longer life. More size also means more money; UPSs can be very expensive. When you increase the draw on the UPS by plugging new equipment into it, be sure that you get more and stronger UPSs; otherwise, your UPS won t last as long as you believe it will. A few years ago, one of the American tire companies released a tire that they advertised as being able to be driven for 50 miles after it has gone flat. The marketing says that this will enable you to get to your destination or to a repair shop without stranding you in the middle of nowhere. Sounds great, right It might get you to your destination, but the only way the extra 50 miles can get you to a repair shop is if you know that the 50-mile countdown has begun. If you don t know, then you are just stranded 50 miles farther down the road. (To be fair, the fine print on the commercial made reference to a required monitoring device.)

The same rule applies to UPSs. A UPS may get you to your destination (the restoration of regular power), but if it doesn t, then when the battery runs out your systems will go down just as hard as they would have before the UPS kicked in. Make sure that your UPS is smart enough to tell your systems or your administrators (preferably your systems) when it is running out of juice so that they can be brought down in an orderly fashion. Be sure you leave enough time and juice for the graceful shutdown of your databases, filesystems, and network services to complete. UPSs can be used for minimal protection against downtime in two ways: Very brief power interruptions. In many parts of the world, especially during hot summers, it is not unusual for a one- or two-second power interruption to wreak havoc on unprotected systems. A fully-charged UPS will, in almost all cases, bridge the gap and keep your systems running through such a brief outage. An orderly shutdown of the system. When the power goes out suddenly, and systems are shut down violently, filesystem damage can result. At the very least, a UPS should be used to give the systems time to shut themselves properly. If the UPSs have more power, they can, of course, keep systems running longer. More power and more time from UPSs can cost a lot of money, and the value that they return must be carefully balanced against the cost. An often overlooked fact about UPSs is that the more equipment you plug into them, the less time they will be able to keep that equipment running. More equipment will cause the UPS s power to drain that much faster. Test your UPSs from time to time and make sure that they still have the capacity you think they do.
