One of, if not the, most popular of my blog posts to date has been ‘Why Cisco UCS is my ‘A-Game’ Server Architecture (http://www.definethecloud.net/why-cisco-ucs-is-my-a-game-server-architecture.) In that post I describe why I lead with Cisco UCS for most consultative engagements. This follow up for storage has been a long time coming,…

Intel’s Betting the Storage I/O Farm on the CPU
I had the privilege of attending Tech Field Day 4 in San Jose this week as a delegate thanks to Stephen Foskett and Gestalt IT. It was a great event and a lot of information was covered in two days of presentations. I’ll be discussing the products and vendors…
How Emulex Broke Out of the ‘Card Pusher’ Box
A few years back when my primary responsibility was architecting server, blade, SAN, and virtualization solutions for customers I selected the appropriate HBA based on the following rule: Whichever (Qlogic or Emulex) is less expensive today through the server OEM I’m using. I had no technical or personal preference for…
The Cloud Storage Argument
The argument over the right type of storage for data center applications is an ongoing battle. This argument gets amplified when discussing cloud architectures both private and public. Part of the reason for this disparity in thinking is that there is no ‘one size fits all solution.’ The other part…
Storage Protocols
Storage is a major consideration for cloud initiatives; what type of disk, which vendor, and as importantly which protocol? Experts will tout one over the other based on cost, performance, throughput, etc. Let’s take a look at the major storage protocols at play in the data center: Small Computer System…
Data Center Bridging
Data Center Bridging (DCB) is a group of IEEE standard protocols designed to support I/O consolidation. DCB enables multiple protocols with very different requirements to run over the same Layer 2 10 Gigabit Ethernet infrastructure. Because DCB is currently discussed along with Fibre Channel over Ethernet (FCoE) it’s not uncommon…
Consolidated I/O
Consolidated I/O (input/output) is a hot topic and has been for the last two years, but it’s not a new concept. We’ve already consolidated I/O once in the data center and forgotten about it, remember those phone PBXs before we replaced them with IP Telephony? The next step in consolidating…
