Video: Dell R610 Overview in Lab

by dave on January 14, 2010


I figured I’d start the year off right and give all of you a bit of an overview on the Dell R610 hardware that I use in my test and development work.  Got 6 of these guys in the other day so, I shot a quick video overview of the hardware and specs for you to take a look at.

I don’t mention the HBAs or CNAs that I use (Brocade, Emulex, and Qlogic) because it does vary a bit depending on the loadout that I’m working with.  Common denominator to everything, though, is VMware ESX4i.

If there’s anything else you want me to provide an overview on, please let me know!

cheers,

Dave

Moving from Block to Cloud: Emulex E3S

by dave on June 18, 2009


It’s not often that I get excited about technology within the storage space. There are notables, of course, mostly that take my love for high bandwidth interconnects (e.g. Infiniband, Rapid I/O) and mash them up with high-speed storage (EFDs, Fusion-IO). That being said, when it comes to the cloud, I’m absolutely estatic when off-the-shelf components can be utilized to get your data from the realm of block-based storage into the cloud-esque realm of object-based storage. Today, we’ll do a quick high level overview of one such technology gives you the freedom of moving from block to cloud (and back).

Is FCoE a viable option for SMB/Commercial?

by dave on October 14, 2008


Host Bus Adapter (Fibre Channel)

Since I work in the SMB/Commercial space as a TC, I routintely am exposed to mixed fabric environments.  With the advent of iSCSI, we’ve seen a proportional shift towards iSCSI as a reduced-cost block storage fabric.  Legacy (2Gb/s) fibre still has presence in specific markets but the uptake of 4Gb/s fibre has been slowing down.  With FCoE being announced as the next logical evolution of converged fabrics and 8Gb/s FC and 10G iSCSI working their way to availability, does FCoE make sense for SMB/Commercial markets?

Future Storage Systems: Part 3b – I/O Expansion Node

October 10, 2008

In Part 3a, we discussed the possibility of a purpose-driven Compute Node based on the Torrenza initiative for the Future Storage system.  This expansion node made use of Hypertransport as a “glue” between the base storage compute node and the expansion node (of computation or I/O flavours) that could be added.  The advantages of that […]

Why wouldn’t the following work? (Future Storage System: Part 1)

October 7, 2008

So, I’ve been toying around with this in my mind for some time.  Essentially, I’ve tried to understand the basic “Storage Processor” limitation of current storage systems and propose an admittedly simplistic design to get around some of the difficulties.  The biggest hurdle, in my mind, is to have cache coherency, low latency memory access […]
