Does anyone here have an informed opinion (probably through practical experience) regarding the iSCSI vs. FCoE speed debate going on? Which method of I/O consolidation and fabric unification is "better"? Of course each technology has its advantages and disadvantages...
I know that Cisco has invested a lot in FCoE and they have gotten large technology partners, like EMC, to join their caravan.
Please dont give me an explanation of each technology and a link to some resource. I know what each technology does and how it works. I am looking for informed opinion regarding performance.
I think that in theory, provided there is no contention, there will be little if any real world performance difference between the two. - If in both cases the hosts have enough CPU/buffers/10 gig connectivity, there's no congestion in the network etc., the SAN has similarly no resource issues processing whichever protocol.
However, I think that in practice, FCoE is the better engineered protocol, just because the perfect world of the above is unlikely, and when congestion/contention occurs, FCoE will handle it gracefully.
I'm resisting linking you to lots of white papers on the relevant standards
I was sort of leaning in the direction of FCoE, too, until I did some more reading. With iSCSI, the packet size can be up to 9K Jumbo frames, whereas FCoE is only about 2.5K. Moreover, FCoE adds more header overhead with 3 layers of encapsulation. Lastly, with 3 of the 4 CEE standards ratified, it's iSCSI that will benfit the most from it, whereas FCoE cant live without it.
