Just over a year ago, superstorm Sandy slammed into the New York metro area, destroying thousands of homes and wreaking havoc with the IT infrastructure in southern Manhattan and low-lying areas of New York and New Jersey. It was the costliest and most destructive storm of the 2012 hurricane season and by some accounts the second or third most expensive in U.S. history.
So what have we learned when it comes to safeguarding IT infrastructure?
Quite a bit: at least according to data center pros who weathered the storm and have some ideas for mitigating damage from similar events in the future, which given what we know about rising water levels, are bound to happen again.
1: Focus on the people, stupid
Big data-center providers have contingency plans to cover acts of nature or man, including provisioning food, water, and cots for on-site personnel. But until Sandy, most of these were designed for a few days of staffing. That changed with Sandy, said Raouf Abdel, regional operating chief for the Americas for Equinix.
“We will prepare for longer intervals. Before we’d stock up for a day or two maybe three, but Sandy showed use we need to go longer,” he said. “We found we needed better sleeping quarters, more water, more food, more coffee.”
Before Sandy, nobody seemed to imagine that highways, tunnels and subways could be out for days on end. Now there have to be plans in place for how personnel can get to the affected area, and for how other personnel can work remotely as effectively as possible.
2: Assess the state of facilities — whether or not you own them
Most data center providers know they need to build new facilities on high ground — Equinix sites in Secaucus and North Bergen, N.J. are above the 100-year flood plain, for example. But when it comes to weather-proofing, more is more.
Providers using third-party facilities need to keep a sharper eye on the physical security and stability of those sites. Ensuring that there are berms or other physical barriers to low-lying doors is a no brainer. Equinix has added waterproof steel doors to prepare for “several more feet of water,” Abdel said.
It’s natural to focus on basements when you think of flooding, but a flat roof can be almost as big an issue. Installation of rooftop gear and piping often leaves perforations that can lead to problems in high wind and rain. So, when you assess your physical plant, look up as well as down, said Mark Thiele, executive vice president of data centers for Switch, the Las Vegas-based SuperNAP.
Make sure there are updated blueprints and other building documentation on site and available to emergency personnel. In an emergency, they will need them.
3: Carefully assess the backup power situation
Even if you have plenty of fuel for backup generators, it won’t help if the generators themselves or the pumps to supply them get flooded in a basement. If this gear must stay on lower floors, make sure it’s fully encapsulated and waterproofed, said Michael Levy, analyst at 451 Research.
Post Sandy, service providers should also make sure they have roll-up generators as well as fuel hoses onsite and easily accessible, said Ryan Murphey VP of operations for PEER 1 Hosting. Oh, and make sure those hoses fit both the generators and the fuel trucks.
And, not to belabor the obvious, make sure there are lots of batteries, flashlights and headlamps stocked, operable and accessible.
4: Bone up on DIY weather prediction
While most data center pros keep an eye on big storms, Sungard Availability Services is making crowdsourced weather watching a part of its standard operating procedure.
As Sandy developed, Sungard staff watched various weather sites and found the amount and quality of information available to be invaluable. For example, the National Oceanographic and Atmospheric Agency sites that simulate storm conditions are “unbelievable,” said Nick Magliato, Sungard AS Chief Operations Officer. “If you map NOAA data to tide charts, you can see how a storm surge might manifest say down the Hackensack River,” he said.
A combo of NOAA, Google Earth and government topological maps, can show a lot about what a storm surge from a 100-year storm will look like in advance, he said. Instead of managing the generic risk posed by a hurricane hitting the Eastern Seaboard, you can simulate what a four-foot tidal surge would mean to southern Manhattan and low-lying New Jersey. ”And we don’t have to hire an environmental engineering firm to do it,” Magliato said.
5: Choose new locations wisely
Obviously in looking for new facilities, it behooves you to make sure they’re on high ground, away from the coastal areas impacted by Sandy and before that Hurricane Irene in August 2011. Two “100-year storms” in two years prompted lots of conversations around the wisdom of keeping data center facilities in surge-prone areas.
Omaha, Nebraska-based Scott Data Center has fielded lots of inquiries from New York metro companies in the past few years, said company president Kenneth Moreano. Major League Baseball, for example, has put its second “hub” at Scott Data Center. MLB’s primary hub — which serves much of its streaming media — remains in New York, but MLB is replicating that capability in Omaha. “Originally Omaha was going to be their disaster recovery or backup location but now we will be their first hub outside of New York City,” Moreano said.
At least “one data point” in most of these discussions with New York area companies is talk of storm-related outages, those infamous “bucket brigades of fuel,” he said. While financial services firms that need extremely low-latency connections to trading floors will keep assets close to Manhattan, there’s no compelling reason for the bulk of data center infrastructure to be in the immediate area given the risks — and given New York’s extremely high real estate prices.
Just some things to think about for next time. Gulp.
