Internal Costs Per Gigabyte — What Do You Pay? 420

CodePwned writes "I recently took over a position at a rather large company where I discovered my group was paying $30 per gigabyte per month! That's $360 per year per gigabyte to our own IT department. While I understand costs are different depending on the scale, redundancy, backup and support methods, there doesn't seem to be any good papers on what range you should expect your costs to be. So far, my research shows an average of $1 per gigabyte or less for internally hosted space. What do you pay?"

    High performance and reliable storage tends to be expensive.
    High performance and cheap tends to require a lot of maintenance.
    Reliable and cheap tends to be really really slow.

    So if they are on a SAN with that one gig spread across 50 drives, there are some applications that need that speed.

      At those costs, one terabyte of data stored for three years would cost roughly $1.1 million. I find it hard to believe that you could legitimately build a SAN that stored 1 TB for that amount of money and not have hit some sort of performance wall that made the expense superfluous. I mean, at some point, you're maxing out multiple 10GigE fibre channels from your SAN and thinking "How can I spend the rest of this money?"

      As I understand, this stems from the idea of outsourcing IT. IT outsourcing companies love this, because they can easily compare apples to apples. "Your internal IT dept. charges $30/GB to host and support your files, but we can do all that for $25/GB!" However, many IT needs don't fit into that model very well. Which model you use really depends on your needs, the size of your company, and the department structure.

    What you may be seeing, especially if you are working for a very large company, could just be a cost allocation scheme, not a real money cost as you are thinking of it. If your department brings in revenue, the organization needs to match expenses to it for purposes of Management Accounting.

    For instance, imagine you know it costs $X to run one of your cost centers. That dollar amount includes everything from the manpower, the equipment, the facility...everything. Now, they need to assign these costs to the departments that actually make money in a way that makes sense. They could do this by carefully costing out each service they provide and assigning an overhead rate, blah blah. That tends to be a pain. You do it if you have to...but you try not to have to. Another, easier, way of doing it is determining a usage metric (CPU hours, GB of storage, number of tickets) and using that to determine each profit center's percentage allocation of the overall cost.

    So, the $60 per GB may not even be close to a market rate for storage. However, if all the departments used twice as much storage next year, the per GB cost might fall to $31 per GB (slightly more than half to account for the fact that there would obviously be more real costs). Conversely, if you convinced your management to contract externally for storage, everyone else might find their per GB cost rise, since the fixed costs would be static.

      Your description sounds about right. But, by using storage as your proxy for all IT cost you are putting perverse incentives for people to use less storage than is right for their business need (or to avoid using central storage, where it can be managed and backed up, and put their stuff on their own external HDDs).

      I think a per person overhead charge, plus a storage charged at closer to cost is likely to work out better.

      Conversely, if you convinced your management to contract externally for storage, everyone else might find their per GB cost rise, since the fixed costs would be static.
