How Do You Evaluate a Data Center?
mpapet writes to ask about the ins and outs of datacenter evaluation. Beyond the simpler questions of physical access control, connectivity, and power redundancy/capacity and SLA review, what other questions are important to ask when evaluating a data center? What data centers have people been happy with? What horror stories have people lived through with those that didn't make the cut?
Beyond the simpler questions of physical access control, connectivity, and power redundancy/capacity and SLA review
Well first of all, I don't know that I'd write any of those things off as "simple". But some other points worth looking into would be:
Cable Management (over or under floor)
Cooling Capacity and Redundancy
Power Quality (not just redundancy)
Age and Condition of Electrical Hardware (ATSs, STSs, UPSs, Generators)
Outage/Uptime History
Fire Suppression System and Smoke Detection System
Maintenance records
Maintenance records
Maintenance records
I'd also ask:
Number of years in business.
Involvement of the owner in the current business.
Number of years the current owner has been in this business.
Also do a check with the Better Business Bureau to see what, if any, complaints had been filed.
And, as always, Google is your friend -- definitely do a search for the business you are considering along with the word(s) problem, issue, complaint, praise, etc!
Find someone you trust who's already a customer. Word of mouth beats any number of white papers or studies or guarantees.
There are basically 3 perspectives from which to evaluate the Datacenter. They're pretty well universal to any IT eval. People, Process and Technology. The datacenter facility itself is only one piece of the puzzle (Facility = Technology, which only accounts for a fraction of the total cost of operating a Datacenter). There are also the people running the datacenter and how they are organized and interact with the technology, one another, and their customers (internal and external). From a people/process standpoint, if you want to give a general "score" to them, you can assess them against the SLM maturity scale. (Read about the Gartner Maturity Model for Infrastructure and Operations) Evaluating a datacenter is going to be a balance between the cost of operating the datacenter and the level of service you require from said datacenter. There really isn't enough information in the question to give you a good answer. Are you looking at evaluating the acquisition of a datacenter to grow into, are you looking for a managed services DC to host your gear with operational support? Are you looking for rack space with pipe and power? If you give more details to your inquiry, I'm sure the community can provide you with some great answers.
You forgot a few:
- Enough qualified *on site* staff 24x7 to deal with all clients including yourself
- 24x7 phone support, with people who understand English and have immediate access to the techies
- Company financial records and history (You don't want someone almost broke or a new startup with no backing)
- These days availability of virtualisation solution and supporting hardware (depending on your application, if virtualisation is an option)
Oh and your emphasis on maintenance records may be a little misplaced. They can be faked. They also may not be available due to security concerns (of their other clients). *IF* you can get hold of them they should be complete. Hardware service level should be part of the agreement and service schedule should be part of that.
