#95 – Quantifying Storage Vendor Guarantees with Chris Mellor and Eran Brown

Chris EvansGuest Speakers

This week, Chris E is joined by Chris Mellor and returning guest Eran Brown.  The team discuss the usefulness of storage vendor guarantees like de-dupe ratios and uptime.  Do vendors use these metrics as a marketing tactic to attract new customers or is there any value in them?

The idea of a sales/marketing guarantee sounds appealing.  Storage vendors have been using them for years to entice customers and offer some sort of incentive to buy.  Most recently we’ve seen de-dupe and compression ratios being a battleground for optimising the cost of all-flash arrays.  Digging down, what’s actually on offer?  How do vendors quantify what these offerings mean?  What’s the penalty if the vendor doesn’t meet the agreement?  Should you get these guarantees written into contracts?
