ESXi/NFS performance optimization

Hi community,

I have a VCL2.2 setup within a blade center, one blade (with more storage) 
is dedicated as NFS server and the rest 13 will be ESXi hosts. The blades 
are connected by BC's internal 1 Gbps ethernet.

I already start to feel the performance pinch when only about five/six VM 
running. I think the NFS server is the bottleneck.

Here is my question: Is there a way to make the VM save the swap and delta 
(.REDO) file on the ESXi's local datastore, so that the NFS server is only 
accessed for reading the captured image? 
Thanks,

Hi,

I find that vmhost profile 'VMware ESX - local & network storage' is the 
solution I am looking.

After set to that profile, .vmx (.vswp and .REDO as well) is created on 
the local store, and referencing the image (.vmdk) located on 
nfs-datastore.

Thanks,

I am using ESXi 4.1, the free version.

Which of the VMware/ESXi provisioning modules are you using?
