Develop a strategy, set your requirements, narrow your targets and make a selection. Those are the steps Evaluator Group partner and SearchStorage.com expert Randy Kerns recommends when it comes time to submit a request for proposal (RFP) to a storage array vendor.
Kerns conducted a workshop on the legwork required to develop RFPs for storage arrays at the Storage Decisions 2003 conference in Chicago.
When developing a strategy, Kerns said you have to take a step back and figure out exactly what is needed for your specific infrastructure. Do you need a storage area network (SAN)? Do you need network-attached storage (NAS)?
In either case, Randy recommended you build out a matrix that pulls all of the specs in one place -- then play a little round robin. Instead of looking at all of the potential arrays at once, try to narrow it down to product A vs. product B, then product A vs. product C, product B vs. C, and so on. This way, you don't miss out on an equal, side-by-side comparison of the products.
Once you narrow down the products internally -- then Randy said the hard part begins.
"Politics trump any technical situation," said Kerns. "You have to understand the business environment and the legal ramifications."
Kerns noted that even after you go through all of the work to narrow down your technology choice, it may not be as simple as just rubber-stamping a purchase. Legalities -- especially in the government sector -- pose increased roadblocks to a final purchase that will satisfy your requirements. Internal politics also play a factor.
