Dave Graham's Blog With the advent of Cloud Computing and the general resurgence of computing grids, data storage has been taken for granted. However, as cloud computing’s storage and access demands continue to grow, the need for an optimized storage layer and hardware accompaniment become even more critical. The general focus has been on computational power, integration points via software (API access, for example), and code portability.  Storage, on the other hand, was considered a commodity to be taken advantage of; a simple pool of storage for whatever data needed some level of retention and access.  However, as cloud computing’s storage and access demands continue to grow, the need for an optimized storage layer and hardware accompaniment become even more critical. In this series of articles (which represent a paper I am writing), I will attempt to examine key a... (more)

Cloud Optimized Storage Solutions: Tiering & Expectations

Dave Graham's Blog In Part One of this Cloud Optimized Storage Solutions (COSS) series, we took a look at the content being stored on COSS and in Part Two at how it is stored. Storage within the cloud is meaningless without a measurable level of performance that it can be compared against. Since there are no established benchmarks that determine performance of storage within a cloud infrastructure, it is reasonable to apply tiering metrics to storage based on content valuation and service level agreements (SLAs) and utilize this as an overarching methodology to judge COSS storage...

Where Community Begins

Nothing tends to solidify a community more than a cause that hits each of us at our base element: our physical being.  In this case, we’ve seen a massive explosion of support within the storage community with folks from NetApp, HDS, HP, IBM, and EMC (amongst many) coming to the aid of Nick Glasgow who is currently undergoing chemotherapy for leukemia.  I’ll let Mark Fredrickson tell the story on his blog, but on a personal note, this strikes very close to home. When I was in college, my brother had a friend who struggled with (and ultimately succumbed to) leukemia.  The devasta... (more)

Why FCoE Is a Good Thing…

This is a tongue in cheek video that I took in one of my labs showing why, for no other reason but fabric reduction, that CEE/DCE/FCoE is a valuable thing for ANY IT infrastructure. A couple of things you’ll notice here are: a.) it’s loud. Sorry about that…this lab is in a thermal chamber and it gets crazy loud. b.) I’m running Qlogic 2562 HBAs (fibre channel) and Qlogic 5802V switching (more switches are coming) c.) My GigE switches are, in a word, terrible (with the distinct difference being the Foundry/Brocade switching which is good). d.) I copt a TERRIBLE NorthEastern accent…I... (more)

Something "Cloudy" This Way Comes!

Storage Sessions at Cloud Expo I love receiving suprise packages.  Way back in January, I got a briefing on a VERY cool server offering from Dell that was going to be part of their DCS (Dell Cloud Services) offering. I, of course, requested one understanding it to be an almost perfect density compute node for my EMC Atmos Virtual Edition testing and design work. Well, what do you think decided to show up on my doorstep today? Say hello to the Dell C6100.  It’s a dual power supply, 4 compute node, 24 x 2.5″ SAS drive, 2U MONSTER of a platform. Yes, Supermicro and Tyan have done thi... (more)
