Where is the problem?? Problem is the storage. All storage resides on the HP ML150 server. For that reason I need to install a server as a virtual storage to run most of the virtual machines running on the server HP ML115 with the exception of firewalls and the DMZ server that resides on the HP ML115's local disk.
For backups I have an external usb disk with 1TB.
You can probably make that work if you don't care much about performance, but it would be much better to toss at least one more drive in the the ML115 - and maybe more RAM in both. Even better if you can add several drives and keep each VM that is active (the firewalls/DNS server, etc. shouldn't be busy but the squid will unless you disable the disk cache) on its own drive. And more RAM would help too.
I would probably take the memory from the 115 and put it in the 150 and have 1 highly usable system instead of a .75 and .50 usable system.
That's if I couldn't buy more memory. I would say 8GB is a min, 16GB preferred, 32GB is great
At this moment I can't buy more RAM.
. Are these single socket or dual socket?
HP ML150 is dual socket, but ML115 not.
Can the smart array be shared between two hosts?
No.
Then I suggest loading all the RAM from the 115 into the 150 (if it's the same type) and have a really good ESXi box and the 115 around as a spare in case the 150 fails.
When monies come available you could buy a second CPU or more RAM depending on what resource is needed most.
