Help! Brocades and McData
Hey guys/gals,
I know very little about SANs but have been asked to find information on the web about which is the better overall switch: The Brocade Silkworm 3900 or the McData 3232? All I can find are marketing blurbs and very little about the technical merits of each device. Which do you guys prefer and why? Any feedback is greatly appreciated. Also, any URLs you may have regarding specifics about performance testing, etc. on these devices are appreciated. -TIA Jeff |

Personally I prefer Cisco, but that's a different story....
Out of those 2 the answer, as always, is it depends. McData is fantastic at passing packets, doing it quickly, and doing it consistantly. That's it, move data fast and reliably. Brocade has a good record as well but not as good as McData. But one thing they have McData does not is a roadmap that actually sees things get to reality. They are progressing when it comes to new technology like fabric based services among others. McData's roadmap today looks frighteningly similar to the one of 3 years ago. Not much has changed. But then again, they were good at packet passing back then too. Hope this helps. ~F On 15 Oct 2003 07:58:09 -0700, (Jeff Specoli) wrote: Hey guys/gals, I know very little about SANs but have been asked to find information on the web about which is the better overall switch: The Brocade Silkworm 3900 or the McData 3232?

Personally, Brocade is better from a secure fabric standpoint.

Hi, Boll,
Could you elabrate a bit more about why Brocade should be avoided due to its RSCNs? Thanks -Yi "Boll Weevil" wrote in message news On 15 Oct 2003 07:58:09 -0700, (Jeff Specoli) wrote: Hey guys/gals, I know very little about SANs but have been asked to find information on the web about which is the better overall switch: The Brocade Silkworm 3900 or the McData 3232?

Price aside, given a choice between a Brocade-3900 and a McData Sperion(ES)-3232, which would you go with and why. To help you answer, know that two of these will straddle the ends of a 91km DWDM connection, so Buffer Credits are an important consideration. I have calculated the required amount to be about 62 at 2Gbps and a payload of 2Kbytes. Are there any other preferences that you like or dislike as well? The question is which HBA are you going to use. If you are thinking qlogic, then do not use the Brocade switch due to RSCNs. Otherwise, the products are comparable. If you will be growing into a larger SAN later, then I'd stick with the Mcdata, again. The Mcdata core switch is better. If you use Mcdata core, obviously it's better to have Mcdata edge switches.

Thanks -Yi In the past post a person named Rene posted nice a RSCN description: Hi, Registered State Change Notifications (RSCNs) can theoretically interrupt fc traffic of members of the same zone. RSCNs can be sent if one HBA connects to the internal switch name server - in fact there are HBA drivers outsite that allows to disable that feature. Anyway, the most easy way to stop RSCNs impact on other host is to follow one golden rule: Never ever build zones with more than one HBA inside. |

Come on, most of the guys here even know that Cisco
build san switches. I'd appreciate if you do other things with your advertising budget.
