Good deal/low price ESXI server

[N3RO]

Dual L5320 (8C/8T) @ 1.86 GHz (Core 2 platform) would be slower than a single FX-8320 (8C/8T) @ 4 GHz in everything...
Dual L5520 (8C/16T) @ 2.26 GHz (Nehalem) would be better in some scenarios, some not. If you'll have 16 machines powered on at all times then okay, but CPU usage still will not be maxed out for most workloads. This platform is rather expensive as well.

If you need to run 16 VMs on the hypervisor with an 8C/8T CPU, then use vSphere to load balance 16 machines without much issue.

The main thing is RAM, you'll want to allocate as much RAM as possible to each machine depending on the OS, 16GB is a minimum for best performance.

What exactly are your goals?

I'll start with 1 L5520 and upgrade later to a second one.

It's possible to run regular DDR3 sticks or only ECC?

Introducing to vSphere, testing multiple Windows Server within different scenarios, fail-over options, etc. and other OSes, and run 2 DaaS. Nothing heavy-loaded. Things I just cant' do on my laptop.

Thank you

I personally run a home brew ESXi box and I will give you some observations.
Purchased this box about 2 years ago now.
- Keep in mind licensing, free ESXi License only supports 4 cores if I remember correctly.
- 8 GB RAM is LOW. I personally run 32GB because it is the max my mobo supports and 16GB was to little for my needs. Upgraded from 16 to 32 about 9 months ago. DDR3 8GB sticks are about the same price per GB as 4GB sticks today
- I use non ECC RAM because my mobo + cpu dont support it and I didnt want to spend the extra money to get it. For a play / testing rig usually not needed to get ECC
- After RAM, Disk IOPS is probably your biggest limitation. Rebooting several VM's can be a pain, or a coffee break :P depending on your view.
- Latest ESXi release installs a GPT partition by default. Not all bios support boot from GPT. Google knows how to install with MBR, I forgot :P
- I rarely max out my CPU, usually my Disks wont be able to keep up.

I purchased my box with the goal of expanding my general knowledge of Windows Server and to have an environment to play around with.
Besides that it also functions as my NAS box with Hardware passthrough of the raid controller to a VM.

Permanent VM's:
- Openindiana + ZFS (this is the NAS box with the RAID Controller assigned to it) - 8GB RAM assigned
- OpenVPN Appliance (VPN Server for remote access) - 512MB RAM assigned
- Windows Server 2008R2 (Download box and remote workstation, my laptop sucks and my desktop needs to crunch when I am not @home :P) - 4GB RAM Assigned
Including overhead this results in about 13-13,5GB RAM used. These VM's are always on unless I need the RAM :P

Hardware:
- i5 2400 (4 core, no HT, 2nd generation i5)
- 32GB RAM
- Intel Q67 chipset mobo (DQ67OWB3)
- Datastores 1x 128GB SSD Crucial C300 (boot), 2 separate 10k WD Velociraptors (came from my gaming rig when I replace them with SSD's, slower than new 7.2k drives I think)
- SASUC8I Inter Raid controller (Flashed with LSI IT firmware to function as HBA), with 6x 2TB Samsung F4 - passed through directly to NAS VM
- 600W Coolermaster Gold PSU
- Fractal Design Define R3 case

Your Mobo and CPU need to support hardware passthrough of PCI devices.

Thank you for your words.

About licensing, is not licensed per physical server with a maximum of 6 cores per CPU? Excluding HT.
