So I’m watching the news the other night and this ad for some new cop show comes on (it was CSI: Abercrombie and Fitch, I think). It looked pretty formula – attractive, fashion conscious 22 year old forensic pathologist meets dead guy, becomes fascinated with dead guy’s life, and solves the mystery of his untimely demise, all in an hour. Formulas can be convenient, since they tend to be based on past, proven experiences, and Hollywood is a perhaps annoying example of that. I tend to day (or night) dream about storage a lot when I’m winding down at the end of the day, and got to thinking about how formulas apply in an area I’ve been spending a lot of time on lately: virtual desktops.
If you’re about to embark on a virtual desktop infrastructure (VDI) project, what formula are you using to determine the storage configuration you need on the back end to meet your performance requirements? Do you have a variable in there that accounts for the storage performance degradation you’re going to experience when you use a standard, SAN array as the storage back end for a VDI configuration? Does that variable assume that you’re going to get at least 30% fewer IOPS out of your storage configuration than you have been getting with that same array when it’s attached to physical servers? Have you budgeted for the additional storage hardware (spindles, solid state disk (SSD), etc.) that you’ll need to bring that performance back up to where you need it to be?
If not, you might want to consider the following:
