Note: I’ve added a couple of corrections below thanks to Stuart Miniman at Wikibon (http://wikibon.org/wiki/v/FCoE_Standards) See the comments for more. I’ve been digging a little more into the HP FlexFabric announcements in order to wrap my head around the benefits and positioning. I’m a big endorser of a single network…

FCoE multi-hop; Do you Care?
There is a lot of discussion in the industry around FCoE’s current capabilities, and specifically around the ability to perform multi-hop transmission of FCoE frames and the standards required to do so. A recent discussion between Brad Hedlund at Cisco and Ken Henault at HP (http://bit.ly/9Kj7zP) prompted me to write…
FCoE initialization Protocol (FIP) Deep Dive
In an attempt to clarify my future posts I will begin categorizing a bit. The following post will be part of a Technical Deep Dive series. Fibre Channel over Ethernet (FCoE) is a protocol designed to move native Fibre Channel over 10 Gigabit Ethernet and above links, I’ve described the…
Fibre Channel over Ethernet
Fibre Channel over Ethernet (FCoE) is a protocol standard ratified in June of 2009. FCoE provides the tools for encapsulation of Fibre Channel (FC) in 10 Gigabit Ethernet frames. The purpose of FCoE is to allow consolidation of low-latency, high performance FC networks onto 10GE infrastructures. This allows for a…
Data Center Bridging Exchange
Data Center Bridging Exchange (DCBX) is one of the components of the DCB standards. These standards offer enhancements to standard ethernet which are backwards compatible with traditional Ethernet and provide support for I/O Consolidation (http://www.definethecloud.net/?p=18.) The three purposes of DCBX are: Discovery of DCB capability: The ability for DCB capable…
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…
