10 things to look for in a data center

Going to the cloud might make a lot of sense for your organization -- but only if you choose a secure, reliable data center that can handle your needs. Erik Eckel runs through 10 essential criteria for data center evaluation.

Everyone's going to the cloud. The cloud's all the rage. Almost no IT discussion is complete without mentioning "the cloud." But when it comes down to it, the cloud is nothing more than systems hosting information in a data center somewhere "out there."

Organizations have discovered the benefits of offloading infrastructure development, automatic failover engineering, and multiple coordinated power feeds, not to mention backups, OS maintenance, and physical security, to third-party data centers. That's why "going to the cloud" ultimately makes sense.

Unfortunately, not every data center is ready for prime time. Some have sprung up as part of a cloud-based land grab. Review these 10 factors to ensure that your organization's data center is up to the task.

1: Data capacity

Data centers are typically engineered to support mind-boggling data transmission capacities. Some feature multiple OCx and SONET connections that can manage Web site demands. Other less sophisticated entities might try getting by using redundant T-3s. Don't find out the hard way that your data center provider failed to adequately forecast capacity and can't quickly scale.

2: Redundant power

Many data centers have online electrical backups. UPSes, in other words. If your organization maintains business-critical systems that simply can't go down, be sure that the data center has a second electrical backbone connection. Only N+1 power grid connectivity, to a secondary electrical source, can help protect against catastrophe.

3: Backup Internet

Just as any quality data center will maintain redundant power sources, so too must it maintain secondary and tertiary Internet connectivity. Buried cables get cut. Overhead cables fall when trucks strike poles. Vendors experience network-wide outages. Only by making sure that multiple tier-1 Internet provider circuits feed a facility via fully meshed backbones can IT managers rest assured they've done what they can to eliminate potential downtime.

4: Automatic hardware failover

Redundant power, Internet, and even heating and cooling systems are great, but if they're not configured as hot online spares, downtime can still occur. It's critical that data centers employ redundant online switches, routers, UPSes, and HVAC equipment that automatically fail over when trouble arises.

5: Access control

The importance of physical security can't be understated. Commerce could be significantly affected if just one unstable individual were able to drive a large vehicle into a busy and sensitive data center. That's why it's important that a data center's physical perimeter be properly protected. In addition to physical access controls (keys, scanner cards, biometric devices, etc.), care must be taken to ensure that, should someone gain access to a data center, individually leased sections remain secure (thanks to additional physical access controls, locks, cages, rooms, etc.).

6: 24x7x365 support

Data centers must be staffed and monitored by properly trained technicians and engineers at all times. It's an unfortunate byproduct of today's pressurized business environment but a fact nevertheless. Systems can't fail. Constant monitoring and maintenance is a must. Certainly, many data centers will run leaner shifts during off hours, but telephone support and onsite assistance must be always available. Further, data center services must include customer reporting tools that assist clients in understanding a center's network status.

7: Independent power

Data centers must have redundant electrical grid connections. That's a given. And facilities must also maintain their own independent power supply. Most turn to onsite diesel generators, which need to be periodically tested to ensure that they can fulfill a data center's electrical requirements in case of a natural disaster or episode that disrupts the site's other electrical sources.

8: In-house break/fix service

One of the benefits of delegating services to the cloud is eliminating the need to maintain physical and virtualized servers. OS maintenance, security patching, and hardware support all become the responsibility of the data center. Even if an organization chooses to co-locate its own servers within a data center, the data center should provide in-house staff capable of maintaining software and responding to hardware crises.

9: Written SLAs

Any data center contract should come complete with a specifically worded service level agreement (SLA). The SLA should guarantee specific uptime, service response, bandwidth, and physical access protections, among other elements. Ensure, too, that the SLA or terms of service state what happens if a data center fails to provide uptime as stated, maintenance or service as scheduled, or crisis response within stated timeframes.

10: Financial stability

All the promises in the world, and even an incredibly compelling price, mean nothing if the data center fails. Before moving large amounts of data and equipment into a facility, do some homework on the company that owns the site. Confirm that it's free and clear of lawsuits, has adequate operating capital, and isn't in financial straits. The last thing you want to do is have to repeat the process because a center fails financially or must cut costs (and subsequently service and capacity) to stay afloat.

Having a great DCIM solution in place is key, in my opinion. I work at and we deal with data centers that upgrade to effective DCIM that protects assets and reduces cost. I wouldn't consider a data center without SOME kind of DCIM in place. Would you?


Many thanks for the information.

Could you please let us know what the estimated costs are for a Web Hosting Data Center? What are the hardware and software requirements please?


Eric thanks for sharing a very good checklist for choosing a data center. One thing we have learned from client stories is that it is best to invest time initially to set up or outsource to 2 data centers that are in geographical separate locations. We had some clients who lost multiple data centers for few days due to hurricane Sandy because the data centers were very close to each other(or backup alternative provided by vendor was in close proximity). And this can be done by not spending too much money by adding minimal services to the second location, like: a.) run only most critical services in hot standby and 2) send your backups to 2nd location and have a plan in place to bring other services up from backup. And data center management software like device42(, also help to keep tab on what you have currently that would be migrated and what would be running remotely.


I agree with Michael's points. It pays to do some due diligence before moving equipment into a new DC. The assumption is always that they will do a better and cheaper job than you can internally. There are plenty of commercial DCs where this isn't the case. I'd want to know they aren't running the facility on Excel spreadsheets. Joel Macfarlane, Director at Centeros


When migrating to the cloud, there are a lot of items to consider outside the parameters set forth by SAS70. SAS70 is now the minimum standard for deciding upon a cloud service provider. Experience in cloud migration and management is equally important. SAS70 certified colocation providers do not necessarily have a good handle on cloud management and cloud solutions. Choose providers wisely. Understand what makes each provider different/better. Ask questions about uptime and Disaster Recovery. There's a big difference in 99.95% uptime and 99.999% uptime. Know what that can mean to your business. I also agree with Michael. There has to be a catalyst (better, cheaper, etc.) and a way to test what your business is hoping to accomplish by migrating to the cloud.


Before moving your IT operations into the cloud, there are several steps that need to be followed. For starters, you should first verify that your cloud provider can test your infrastructure in the cloud and test your applications to determine if service requirements are met. In addition, you should also ensure that your provider can effectively manage the infrastructure in order to guarantee there is no downtime for your applications. It is also critical to gain insight into your equipment before making a move to the cloud more specifically, how its being utilized, what capacity is available, where its residing, how much power its using and to have the ability to test scenarios prior to change. Keep in mind that when you move something to the cloud, you are acknowledging that another company can manage your IT requirements better and cheaper than you can. In order to come to this decision, it is crucial that you first complete the steps outlined above. Armed with this insight, data center managers will know whether their existing infrastructure is up for the challenge and the resulting benefits that result from the cloud transition. - Michael Helms, director of product management, Avocent division of Emerson Network Power.


That would be ideal to simply ask for a SAS 70 report. However, it has been my experience that SAS 70s only provides you assurance that some control measures are in place (not necessarily followed with best practise or reported accurately) and that the company that pays for a SAS 70 must have some financial means to pay for it. Ask as many questions about the SAS 70 provider as you would about the data center.


The industry I work for actually requires us to be able to provide the SAS70 reports for each vendor that we outsource to. The SAS70 basically covers all of this and then some.
