The following was just a short note I wrote in an internal discussion about FCoE vs. iSCSI vs. NFS – and spurred by Tony Bourke’s discussion about methods for implementing FCoE. This wasn’t intended to be a detailed analysis, just a couple of random musings. Comments as always are welcome. —– While NFS and iSCSI [...]

Update on the 8Gb FC vs. 10Gb FCoE Discussion
By far, the most popular post on this blog has been my discussion on the various protocol efficiencies between native 8 Gb/s Fibre Channel and 10 Gb/s Ethernet using Fibre Channel over Ethernet encapsulation. I wrote the original post as much as an exercise in the logic as it was an attempt to educate. I [...]

One of the most often requested features in the early days of UCS was the ability to directly attach 10GE storage devices (both Ethernet and FCoE based) to the UCS Fabric Interconnects. Up until UCSM 1.4, only two types of Ethernet port configurations existed in UCS – Server Ports (those connected to IO Modules in [...]

READ MORE »8Gb Fibre Channel or 10Gb Ethernet w/ FCoE?
Update 2011/01/31 – I’ve added new thoughts and comments on the subject here: http://www.unifiedcomputingblog.com/?p=234 Which is better? Which is faster? I’ve been stuck on this one for a while. I’m traditionally a pure fibre channel kind of guy, so I’ve been pretty convinced that traditional FC was here to stay for a while, and that [...]
READ MORE »UCS Books
I often get asked by students if there are any other resources (beyond those I’m linking to) to get more information on UCS. Silvano Gai, along with Tommi Salli and Roger Andersson, published a book back in March of 2009 that includes a great history of the drivers and goals behind the design of UCS. [...]
