Thanks for your advice.

I suggest that you need a minimum of 16GB/node (2GB/core) and possibly
> 32GB/node (4GB/node).

8 Gb/node is enough for types of applications we are going to run on this
cluster. Additional memory stickscan be added later if necessary.

Why is IPMI so important? Because this is small cluster, we can physically
inspect the faulty modes, not a big deal.

I check the pricing, IPMI is extra $100/node or $4000/40 nodes=2 extra
compute nodes. We are on tight budget, and every penny matters. That is why
I sent this email to get advice concerning pricing.
