Re: MSCS and LOAD BALLANCING on the MSA1000
"So the best that you can do is static load balancing with SecurePath in a cluster. Use something like Perfmon to get an idea of what your disk access/load is like, and then set preferred paths in SecurePath, and split them up that way. It may take a couple of tries to get it well balanced."

Re: MSCS and LOAD BALLANCING on the MSA1000
You simply cannot load balance logical disks on an Active/Standby controller combination. Once you try to move one logical disk over to the Standby controller, it becomes the Active one and *ALL* logical disks come online here.

Re: MSCS and LOAD BALLANCING on the MSA1000
But please be aware that even with these controllers, dynamic load balancing is not supported in all cluster environments.

Re: MSCS and LOAD BALLANCING on the MSA1000
you need to read the whole sentence. I don't see a simple statement that says this is true.
Let's take the first sentence, for example:
""Dynamic Load Balancing is supported with Secure Path V4.0C for Windows and Windows Workgroup Edition **with certain storage systems** in a Microsoft Windows Cluster Server (MSCS) environment, as detailed below."
You see, it says "with certain storage systems".
Go to the table and you see that no listed operating system does support Dynamic Load Balancing on the MSA1000. It is not possible for the reasons I have written above (single controller port, active/standby controller).
