I have this new 1U server with me which I plan to install OpenERP 7 open source.
2 x Intel Xeon 6C Processor Model E5-2620 95W 2.0GHz/1333MHz/15MB W/Fan
4 x 8GB (1x8GB, 2Rx4, 1.35V) PC3L-10600 CL9 ECC DDR3 1333MHz LP RDIMM
4 x IBM 1TB 7.2K 6Gbps NL SAS 3.5in G2HS HDD
It will cater multi companies (around 1 group and 10 subsidiaries). Total users around 80. But not all will use at the same time. Probably concurrent users around 30 - 40 at 1 time.
I have 2 options to install:- a. Install Ubuntu 12.04 and OpenERP 7 directly into this server. Thus can gain full power for this. or b. Install Proxmox or VMWare. Then create a few VMs with sufficient power.
VM1 = OpenERP Server, Web, Addons (1TB, 15GB virtual memory, 16 cores vprocessors)
VM2 = PostgreSQL Database (separate from VM1)
Which one will be a better approach?
I read in the old forum, i think people going against the idea of virtual machines. But how about with my specs?
If I can use virtual machine, I do prefer. I can always upgrade my memory to 120GB or add 4 x processors. At least it is cheaper to buy additional boxes.
Any help? Thanks.
