NetApp VSC Performance

This is related to the 4.2.2 version.  Essentially, the JVM that is installed for the NetApp VSC, defaults to the following:

Initial Heap Size : 64MBMax Heap Size: 1024MB What does this mean?  It means that if you deploy a VM w/ 8GB of RAM to install VSC on, it will only EVER use 1GB of RAM.  The VSC (4.2.2) also tends to have performance issues when dealing w/ larger environments.  There is an article somewhere, but I can't find it for the life of me right now.  Anyway to fix this issue, you need to modify the wrapper.conf file.
This is typically in the installation directory of C:\Program Files\NetApp\Virtual Storage Console\wrapper\wrapper.conf
The lines you need to modify are:
# Initial Java Heap Size (in MB) wrapper.java.initmemory=1024
# Maximum Java Heap Size (in MB) wrapper.java.maxmemory=4096
Now you 'can' up the heap to 4GB max if you think it needs it, but I'd recommend looking @ "Active Memory" stats of the VM this VSC runs on to make sure it 'actu…

I was lucky enough to play w/ some early builds that Steve put together and now it's finally a 1.0 product.  I highly recommend downloading and playing with it in the very least.  It is a free download.

The one bug that I remember reporting, that doesn't appear to have been fixed yet though is that the client doesn't understand folders in the hosts & clusters view.  So if you have clusters/hosts in folders, it will not enumerate those in the client.  So it's rather useless to me currently, but should work fine for most people.
