Great questions. I work on the NetApp Realize tool which helps customers estimate how much money they would save by increasing storage efficiency through more efficient hardware and by using technologies like dedupe, thin provisioning, RAID-DP, FlexClone, etc. Here's how you can measure these efficiencies.
- Power, cooling: You can get a good estimate of power consumption if you know what kinds of disk drives you have, the PUE (power usage efficiency) of your datacenter, and how many raw TB of disk you've got. This is how NetApp Realize estimates it. If you switch to more efficient hardware (bigger disks, denser shelves), you use less power/TB. If you need fewer TB because you used dedupe or FlexClone, you use less power.
- Admin costs: If you know you need fewer FTEs and you know what it costs to employee a FTE for a year, you can easily estimate the savings. BUT, you are right that most companies who achieve storage management efficiency gains are not planning to make the extra employees redundant. (And if they are, they're not going to tell the admins in advance.) The NetApp Realize tool is good at estimating how much labor the customer can save, but some customers don't want to include that savings, telling us, "No matter how efficient your storage is, we're not going to fire an admin." I have not seen anyone convert their IT workers' happiness into a money savings. But you can measure TB/FTE and employee turnover rate and convert both of those into cost savings for the CIO/CFO.
- Time to Market: We do have some customers measuring how Efficient IT improves time-to-market. Check our Suncorp Built-on-NetApp story. I think most of our customers are happy to just measure IT efficiency in terms of how quickly they can deploy new storage, new servers (virtualized or physical), and new applications. But the benefits of Efficient IT on the rest of the business can be very real, and we would love to see more customers measure it.
Other thoughts on measuring efficiency....
- See the NetApp Efficient IT site here: http://www.netapp.com/us/company/leadership/efficient-it/
- For a quick and easy estimate of Storage Efficiency savings, try the Efficient IT Calculator.
- To find out how many NetApp TB your customers have deployed, you can use MyAutoSupport (login required). Your customers can use it too.
- To discover both NetApp and non-NetApp storage kit, use management tools like NetApp SANscreen or Akorri BalancePoint.
- If you want a more accurate power consumption management without advanced UPSes, you could use a cabinet with a metering PDU. Or get a clamp-on ammeter.
- We've seen a lot of customers enjoy (or impose) labor efficiency savings by keeping the number of storage FTEs flat while adding more storage. If they can grow capacity 30% annually for 3 years without adding headcount, then either the storage is getting easier to manage or the employees are getting better at managing it (or the admins were previously spending too much time playing Angry Birds).
- Other customers report that after switching to NetApp, they have the same number of storage admins, but the admins spend far less time provisioning storage and far more time planning for application growth and virtualization.
- If you want to use NetApp Realize to help your customers estimate storage efficiency savings, the tool is available to all authorized (authorised in the UK) NetApp partners.
