Are “enterprise” drives worth the extra cost in a RAID enclosure? The reason I ask is I’ve had 2 of 4 Seagate ‘consumer’ (7200.12) drives fail in my (Other World Qx2) enclosure. The two drives that failed were maybe a year old, well short of any ‘MBTF’ expectation. Enterprise drives cost nearly twice that of consumer drives.

Single-parity RAID is under attack. Caching is the hottest trend in storage. The end of the high-performance disk drive is imminent. What happened? Increasing areal bit density has caused disk capacity to grow much faster than disk performance. A presentation at Storage Networking World by Ronald Bianchini of Avere exposed the mathematics of this phenomenon.
We Hold These (Storage) Truths…

I usually welcome discussion (and even argument) about the things I know best: There is always more to learn, and the best insights come through engaging those who disagree with us. But some ideas have been argued so well for so long that they deserve enshrinement. For example, although non-scientists like to argue about evolution [...]
Iomega Grows Up and Moves Out of the House
April 16, 2009 By 12 Comments
Iomega has been a staple of the desktop computing environment for decades, but the company’s products have never been quite at home in even small corporate data centers. That changes today with the introduction of the iSCSI StorCenter Pro ix4-200r. As of now, EMC’s SOHO storage subsidiary is a serious challenger in the small business [...]
Drobo For Pros But Not Me

DroboPro is here, and it’s quite a compelling offering. It’s generating buzz (DroboPro was the number one trend on Twitter for a while on Tuesday) but is it deserving? In a word, yes. But I’m still not going to buy one! The Drobo for Pros Just as in Apple’s Mac and MacBook lineup, the “Pro” [...]

Like clockwork, VMware has cranked out another update to their flagship enterprise product, ESX 3.5. The last update came out in early November, 2008, and included some major new functionality. What’s in store this time to intrigue storage folks? Not much. For more information on earlier updates, see my articles: Storage Fixes in VMware ESX [...]
The New Mac Mini is Finally Here!
March 3, 2009 By 8 Comments
I’ve been waiting on a Mac Mini to replace my sluggish and crash-prone Firefly/NSLU2 home music and file server, and Apple finally delivered the goods today, after leaving us in the lurch at Macworld 2009! I’ve placed my order for a base-model Mac Mini, and look forward to using Apple’s iPhone Remote with the Airport [...]
How I Learned to Stop Worrying and Love Storage Automation
February 9, 2009 By 10 Comments
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 [...]
Of Emulated Fibre Channel, Virtualization, And The Right Tool For The Job
December 12, 2008 By 21 Comments
EMC’s Chuck Hollis is one smart guy, and a very verbose blogger. As usual, he sparked a bit of a storm recently when comparing unified storage on EMC’s Celerra NX4 to NetApp’s multiprotocol FAS2020 filer. But it was one phrase in particular that got the attention of Alex McDonald and Kostadis Russos of NetApp, Martin/Storagebod, and Tony [...]
Top Ten Innovative Enterprise Storage Hardware Products
November 15, 2008 By 13 Comments
Looking around at the enterprise storage landscape, it is plain that certain archetypes rule: Monolithic enterprise arrays, dual-controller modular arrays, standard-sized hard disk units, NAS servers, tape libraries. Are these really the optimal designs for storage in our modern open systems world? On the contrary, I suggest that the enterprise storage world we know was [...]
