any significant electrical event. Be sure to add surge arrestors to copper network and telco cabling as well as wall power. These can be conduits for an electrical surge. Were you involved in any "black-out" situations during hurricanes? If so, what were the first steps you took to restore your systems? What types of precautionary steps did you have in place? Power outages always accompany weather events. We have gotten used to them here in Florida. Fact is though that a hurricane is a phased disaster scenario. That is to say, there is a lot of advance warning that the storm may come your way. So, you can take some proactive measures and power everything down in plenty of time to comply with an evacuation order.
A few years ago, we did have problems during an
abnormally cold winter. Power was traded from our
generating facilities to northern grids that needed it
for heating. The result was rolling outages during
Christmas Day. But, companies had gone to some effort
as part of hurricane planning to work with their
utility service providers and ensure that redundant
switching equipment was used to supply them. When one
set of gear was taken out of service as part of the
rolling outage, they were still up and running on a
different set of gear. It just takes preplanning. After events like the rolling blackouts in California, do you think most of the companies in the affected regions were prepared for this?
Nope. Like anything else, people tend to put the past
behind them. Protection costs money and CFOs these
days often have a hard time justifying expenditures
for capabilities that, in the best of circumstances,
would never need to be used. Moreover, distributed
computing has increased the number of vulnerable
assets to power problems: Things aren't collected
inside the glass house of the data center anymore. So, most companies are a target-rich environment for
power-related events. Protecting a lot of distributed
things is more expensive than protecting a lot of
centralized things. Money is in short supply in
most companies today. What should admins do as a post-mortem to this event?
Look hard at this event from the standpoint of
distances between your primary and backup facility or
hot site. The Fed wimped out on specifying a minimum acceptable distance between facilities after 9/11, but that doesn't mean that companies can't take the initiative themselves. Your backup site should not be served by the same power supplier or delivery infrastructure as your primary. It's as simple as that.
Secondly, look seriously at your internal power generation and power protection capabilities. Spending a few bucks now can keep equipment in service longer and possibly cut down on transient-related software and hardware errors.
