How I Learned to Stop Worrying and Love Storage Automation

This is how we used to avoid hotspots in 1998: Carefully planning every detail of the storage layout.

The first storage performance horseman is spindles: If you don’t have enough disk units, performance will suffer. I have been laying out storage on enterprise arrays since the dark ages, and one of the first lessons I learned was allocating data to avoid hotspots. I remember spending hours back in the 1990′s hunched over custom Excel spreadsheets [...]

The Difference Between “Integration” and “Frankenstein”

Frankenweenie saves young Victor in Tim Burton's macabre short film

When is a solution integrated and when is it a Frankenstein-like mashup of tangled tech? Apparently, that line is crossed when it’s your competitor’s offering… In my time in the storage industry, I’ve seen enough franken-storage come and go to make me skeptical whenever a new “integrated” solution is announced. But a lot of this [...]

Flash Forward or Flash Back?

This is part of an ongoing series of longer articles I am posting every Sunday. The tech industry has been buzzing about solid state drives (SSDs) again lately, but many questions remain. Even after many major vendors (Apple, EMC, and Dell to name a few) have introduced NAND flash-based disk into their core products, it is [...]

Is Flash A Disk Or A Cache?

Flash, Cash, Disk

There is a battle shaping up in the enterprise storage industry. On one side are those who see flash storage as an upgrade for the disk drive, and on the other are those who see it as a cache between the CPU and the drive. It’s a fundamental difference of opinion – flash chips can [...]

SSD: So Close and Yet So Far

Solid state (NAND flash) storage is all the rage right now, but there are many lingering questions regarding its true performance, reliability, and cost. But no question is more important in determining its ultimate usefulness than that of location: Where should flash storage be placed to maximize return on investment? Storage companies have argued that [...]

Compellent Does Enterprise SSD Right

Yes! Compellent has just announced at Storage Networking World that they’ll be adding enterprise solid state drives (SSDs) to their excellent fully-virtualized storage arrays. Why is this worth shouting about? Simply because their automated block-based tiered storage architecture ought to be able to really take full advantage of the performance offered by SSDs. If you’ll [...]

Flash! EMC’s DMX is the New New Thing Again

Who’d have thought that EMC’s storage teenager, the Symmetrix/DMX, still had the ability to surprise us with something new? Well, as reported just about everywhere, EMC today introduced two major new features in the DMX. But don’t get fooled – this is still traditional high-end EMC stuff, and you had better be sitting down when [...]
