Interoperability of Nexus 5020

Rdfcoe — Fri, 14 Aug 2009 09:44:07 +0000

I am testing different architectures with a Nexus 5020 which has a module of FC ports. Anyone could tell me if the Nexus 5020 has interoperability with the FC Brocade switches as the DS 5000B or the 7500?

Windows Logical Disk Manager

I am running a DS4200 IBM SAN box with dual controllers connected to 2 brocade switches . One of the servers has 2 single port Qlogic HBA’s connected to each switch. LUN #3 and #4 have been setup on the Storage array and connected to the server. The server picks up each LUN twice. The SAN works fine and windows only allows connection to 1 instance of each of the LUNS. Multipath is being used by the IBM storage manager. What could be the reason why 2 LUNS are shown under windows 2003 server logical disk manager

I have an HP eva5000 SAN with 2 contollers and 2 x 16 ports brocade switches – I have purchased two addtional 16 port brocade san switches – how do I go about adding them to the fabric? Core Edge design maybe?

Setting up an extended fabric over DWDM

A SearchStorage.com reader recently asked:

I am attempting to set up an extended fabric over DWDM. I have two 32-port Brocade 3900 switches on either end, both running version 4.1.2 Fabric OS. We have two Nortel OPTera Metro 5200 (DWDM) cards on either end. Unfortunately, I have found out that these cards do not provide local buffering, therefore, I must set up an extended fabric via the switches.

I have turned on long distance mode on all switches in the fabric. I have made sure that each port connected to our DWDM cards, is the only port used on the ASIC (since buffers are shared across the ASIC). I have attempted to set the connected ports to the L2 long-distance level (command used: portcfglongdistance port# L2 1). With all the settings in place, I am still receiving CRC errors when running various spinfab/port tests.

I believe that my problem may be that I am not currently using Extended Long Wave (ELW) SFP modules (I am currently just using 2 GB SFP LC modules).

Before I purchase a few of these modules (and the appropriate 9 micron single-mode fiber optic cables), I thought I’d confirm if others agree with my assessment of the situation. If not, what else might I be missing?
