Brocade 3900 versus McData Sperion (ES) 3232...
Hi:
This is not strictly a Sun/Solaris question, but many talented people tuned in have good information to share, so I included the group. 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. What is the exact problem with qlogic and brocade ? Thanks ! Greg G |

What is the exact problem with qlogic and brocade ? Thanks ! Greg G Hi, Registered State Change Notifications (RSCNs) can theoretically interrupt fc traffic of members of the same zone. RSCNs can be send 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. I personally have build up approx. 30 SANs over the last 3 years (Brocade, McData, Inrange) - ever following that rule, and have never seen RSCN problems. Rene |

I'm a fan of the McData's just because I find them easier to work with. I
like the nice simple GUI you get with the McDatas and that if you do have to do something via CLI it's still fairly intuitive. Mark "NYCeyes" wrote in message om...
