The ratio of storage admins to data pool size?
As an industry rule, how many storage administrators should be on staff per terabyte of data? We currently have 20 terabytes of data on all platforms of storage and there are only two administrators for this amount of data.
There have been several reports from analysts that go into the requirements for storage administrators
based on a specific vendor's storage products but, I haven't seen nor heard of any specific ratios that have been established of storage administrators to overall storage pool.
This may be a very hard number to quantify as I have seen a large disparity in the number of storage administrators to the total storage pool size, everywhere from a couple in a 50 terabyte
environment to five in a
20TB environment but this was based on the storage devices being used and the SLA
s in place more than the size of the storage pool.
Also, when you look at the storage administrator numbers, are you including the number of vendor personnel involved in the management of the environment or is this just a number of actual company employees that manage storage? Tape backup
included? As you can see from my comments, this is a bit harder than just looking at the storage pool but actual looking at the roles that each admin has and the goals of the organization.
Let me know if you have any questions or concerns.
