Lefthand P4000 and SRA

Equallogic, disappointing yet still awesome

Comment to Dell:

Get your act together! This array is not cheap by any means. I expect that proper testing and documentation is done for all supported solutions! I don't blame the support personnels in this case. They had as much information as I did so how can they help me properly?

HP P4000 SAN Solutions - Issue While an Upgrade Is Interrupted

Something to look out for with the P4000

Sometimes when an upgrade is interrupted or a node is restarted during the upgrade, the upgrade process may still run. When trying to run the upgrade again, the following message may appear:
Use the backend to check the process running on that node. Rebooting the node is not a solution. Some process can start running again after the restart. Kill any upgrade process found using the command kill .

This guy loves his P4500 and p4300 Lefthand SAN

Horrible iSCSI performance with Lefthand

He thinks this is probably just a misconfiguration....

I'm only testing with 1 nic as it also should be able to give 900mbit performance on the vmware enviroment.

Though I tried making 2 vmkernel NICs with different IP's on the same vswitch and bound them to iSCSI... then enabled Round-robin.

Has made no difference.

I don't think that the issue is related to load balancing tasks, but rather a communication issue between the vmware and the lefthand. The storage works perfectly when testet on a Windows 2008 server using MS iSCSI Initiator.

So it should be software related like a driver problem, misconfiguration or missing iSCSI tweaks. I just don't have a clue where the problem is.
