So at the day job we’re looking at implementing a SAN along with moving server to something virtual (VMware, Virtual Iron or Xensource) . We like the offerings from LeftHand Networks for the SAN. It’s a software based SAN approach will allow us to grow as we need. We’ve got the quotes from them, but the execs are still leary about spending that much money. It’s a typical battle that everyone in IT fights, but we’re finally making progress.
Last weekend LeftHand released their SAN/iQ as a VMware appliance. This is very very awesome. This allows us to test the functionality of it on our network without getting the vendor in here with a SAN on loan that we end up buying because we’ve already started using it on our production network.
We’ve got an AIX server setup with our production data and have it connected via iSCSI to the appliances setup in a two node cluster. Testing so far has been really good over a 100mbit network. Speeds are similar to the SSA drives our production AIX server has. Will definitely update when we have tested it more.

LeftHand should be posting an ODM (or instructions) to create an ODM so that AIX does not restrict queue depth to 1 soon. Unfortunately at this time, even if you specify in SMIT a command queue depth greater than 1, AIX currently only sends commands 1 at a time to generic disk targets. (Unless the target returns that it supports NACA=1 on the device inquiry.)
I would be interested in any assistance/additional information the AIX community has on ODM creation.
I look forward to seeing your results and I am interested in understanding how you are testing.
Sincerely,
