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 capabilities based on application set. Within the concept of Information Lifecycle Management (ILM), there exists the idea that storage can be “tiered” based on criticality of need, application storage performance, or other derived metrics that couple relative responsiveness and bandwidth...

Cloud Optimized Storage Solutions (COSS) Explored

Dave Graham's Blog In part one of this series, we discussed the nature of content within the cloud. After determining the nature of the content being stored, it is important to understand how this unstructured and structured content will be stored. The mechanism for storage has significant impact on a provider’s Service Level Agreement (SLA) to the end user and can also promote the concept of tiered storage within the cloud as well. To evaluate this storage mechanism, you need to pull apart the storage path to determine what influences it has on the content being stored.  Techn... (more)

Welcome to the next generation: Symmetrix V-Max is here…

So, it’s 1201am and…well, now you know what we’re talking about, hinting about, laughing about, and honestly…what we’ve been waiting for.  The Symmetrix V-Max is here and it’s ready to drop the hammer on what you know about storage. What’s in the box? Simply put, the Symmetrix V-Max ™ is designed from the ground up for scalable growth in virtualized datacenters.  While that sounds more marketing than, well, reality, it isn’t.  When you look at the way the V-Max was designed, you’ll understand and appreciate what the engineering staff had to go through in order to make this hap...

Why Policy is the Future of Storage

As many of you may know, I work for EMC’s Cloud Infrastructure Group as part of the Atmos solution team. In this role, I’ve been blessed with getting a closer look at where the future of cloud storage is going as well as some of the drivers that will get it there. In this post, I’d like to talk a bit about policy and how this will shape the future of storage. I’m going to keep this as abstracted from product as possible, but where appropriate, I’ll try to show you how products are implementing this technology TODAY. What is Policy? By definition, policy is “[an] action or proce... (more)

Life with Qlogic’s 5802V

If you follow me on Twitter at all, you’ll know that I’m a big fan of Qlogic.  I appreciate the functional simplicity of what Qlogic designs encompass as well as the “get business done” attitude that they bring to their switches, HBAs, NICs, and CNAs.  Imagine my happiness, then, when I got ahold of one of their latest “edge” fibre channel switches, the SANbox 5802V.  The SANbox 5802V follows the typical edge-switch formula: 20 SFP ports for either 4Gb/s SFPs or 8Gb/s SFP+, 4 stacking ports that default at 10Gb/s Fibre Channel connection and can be upgraded to 20Gb/s FC when ad...
