I'd like to buy this guy: DL 380 G7, http://www.pcconnection.com/IPA/Shop/Product/Detail.htm?sku=11578414&cac=Result
it's coming with 24 GB
q1) what should be the best way to upgrade the memory to utilize the best performance? Right now it has 6 slots occupied with 4 GB modules. Is it possible to add a new 8GB module to this config or should it be always in pairs of the same type (again from best practice point of view)?
q2) I want to establish vmware esxi on it and put the following VMs on it
- development VM (PHP/MySQL) development - 2 GB
- VM production hosting of PHP 5.0 sites - 6GB
- VM production hosting of PHP 5.3 sites - 6GB
- VM production hosting of ASP.NET sites (couple, low traffic) - 6 GB
- mercurial repositories (source control) - 2 GB
I don't have two much load from production VMs, approximate traffic per month on all these 3 VMs is planned at around 200-300GB with 20-30k of visitors across all sites deployed in these VMs
anything you will suggest to make system more robust - from configuration point of view, memory, cpu?
Later on, I'd like to shift to VMWARE Essential Kit plus with HAvailability, but right now I do have only 10-14K Budget and can't get 3 servers within this price + VMWARE license (3900)
I thought more about potential alternative and here is what I found: http://www.pcconnection.com/IPA/Shop/Product/Detail.htm?sku=11534294&cac=Result
If I buy 2 servers with HDDs I still be within the budget. But this gives me ability to distribute the VMs accross 2 different physical servers (still not managed through vCenter and no HA), but my thinking is that later on when I need a 3rd machine - I'll buy a Essential Kit Plus, that has HA and basic vCenter license.
What do you think about this option/idea?
