As someone that implements Brocades SANs on a semi-regular basis, I thought I’d stop by their stand and see if they had anything interesting on show and it turns out they did.

The project I am currently working on has a number of Brocade fabrics (4) after adding 3 new ones and managing them would have been a pain if not for Data Center Fabric Manger.  However, there is one massive limitation with DCFM and that’s the free version only manages a single fabric.  ‘What do you expect for free?’ I hear you cry, well I expect the jump up from the free version to be a bit more incremental than it currently is.  If you want to upgrade you can, to the Enterprise, which will cost you a substantial £30k list.  Now this is not bad if you push Enterprise to its limits (1000 ports in a single fabric), but what if you only have 200 ports?  well Brocade have obviously noticed this discrepency and are releasing a middle level version and are hoping to release in the next few months.

Something else of interest was the vCenter plugin that connects directly with Data Centere Fabric Manager and can trigger actions within vCenter based on policies set at the fabric level.  If an HBA’s bandwidth becomes saturated, a policy can send an alert to vCenter to move it to a host with greater HBA bandwidth availability.

All very neat stuff and the demo worked, so check it out if you deal with Brocade kit.

I recently came across a problem whereby a Rescan SAN was taking an absolute age, like 15 minutes from the VI Client. Now I love the VI Client, but sometimes it just doesn’t give you enough information when it is doing things. To be fair most of the time the verbose information is simply not needed, but when things go wrong it is a god send.

In comes the Service Console command line, more specifically the esxcfg-rescan and esxcfg-mpath commands.

I don’t know if you are like me and feel initially a little bit nervous about messages that contain phrases like “there may be some interruption to I/O”.

Anybody using Brocade Fibre Switches on a regular basis will notice that sometimes the web interface can sometimes be, shall we say funky!

It sometimes show defragmented fabric in the web browser, but there is no reason for it etc.

Here’s an overview of some useful commands that you can execute from the Telnet command line:
