Hi Chuck,

Completely agree. And I highly appreciate the focus on the basics of enterprise storage - the stuff that made EMC enterprise storage market leader in the nineties. Sometimes these days, we take certain principles for granted and start talking to our customers about all the great innovations we made in recent years. But I believe that pointing out the subtle fundamental differences between storage architectures is the starting point.

I talk to database engineers and architects a lot, and for them there is often no difference between storage boxes from various vendors - even JBOD will do as long as they think they have enough spindles - sometimes with an overkill of DRAM or FLASH cache modules in front of them.

Until pointed out that enterprise storage protects you very well against availability issues and silent data corruptions (leading to database block corruption). And forget for a moment the marketing "million iops" numbers achieved in ideal lab circumstances with well-balanced, non-skewed IO workloads: Enterprise Storage guarantees *predictable* performance service levels - even in harsh conditions (caused by a mix of lousy apps - or as you called them, crapplications :), rogue ad-hoc queries, concurrent backups running, broken cables or failing disks, and with active snapshots and synchronous remote replication enabled).

Only after people understand that, it's worth discussing innovations such as automated tiering, storage federation, flash etc.

Best regards from Holland,

(Disclosure: I work for EMC)
