Re: [Wg-test-framework] Proposed hardware shopping list

As I said, here are some questions on this.

1) Does it make sense to add a:

SanDisk X210 SD6SB2M-256G-1022i 2.5" 256GB SATA 6Gb/s MLC Internal Solid State 
Drive (SSD)

as a fast root disk to each mid-range server.  Currently about $190 each, for a 
total of $380.

2) How big should the logging disk(s) be?
    3TB disks look to be about $120 each (PH3300U-1I72, 3 Year Limited 
Warranty) or
        $200 each (WD3003FZEX, Limited Warranty period (parts): 5 years).

3) How do we handle backups? More disks, usb external disks, or something else?

(As discussed, I think.)

Initial hardware requirements

  Operational servers

   * Two identical mid-range servers with (say) 32G of RAM
     Two machines provided in case one dies for some reason.
     (Recovery strategy is to have backup of each VM on each
      server, and to manually bring up the backup VMs.)
     Full on-site warranty.

     To be used as:

       - firewall / NAT gateway  (dom0)
         so each has a global internet connection

       - VM host for infrastructure VM(s)
         osstest probably wants about three infrastructure VMs
           one for pxe/dhcp/etc.
           one for the database
           one for osstest itself etc.

     To be running Debian wheezy with Xen, toolstack xl.

  Test boxes

   * 24 low to mid end test servers, in pairs or quads
     from a variety of manufacturers
     and a mix of CPU vendors
       eg   6x Dell (2x R210, 2x R310, 2x something a bit bigger?)
            6x HP equivalent
            6x equivalent from another big name vendor
            6x no-name servers from supplier(s) local to our colo,

     Minimal warranty


   * One server to be a serial port concentrator running sympathy
     (for osstest) and/or xen use machinery (for xenrt)
        - with a 32-port serial PCI card (eg Rocketport)
        - ideally two PCI slots
        - can be very low-end
        - full warranty
     If this fail catastrophically we replace it with something
     similar from a local supplier and restore from backups.
     Separate from operational server VM hosts to avoid complicating
     VM hosts with hardware support (eg, to avoid PCI passthrough
     of serial port concentrators etc.)

   * One gbit switch for internal network
