  • Archive post: Homebrew ESXi + Openfiler iSCSI

    0

     

    finally got our home (office) brewed storage (openfiler iscsi) into the datacentre, to maximise the dell r805 server.
    Decent specs: HP DL380G3
    • 2 x 3.2ghz xeon
    • 12 gb ram (yes, i know, overkill)
    • 6 x scsi 73gb (1 x ESXi installation, 5 x raid 5)
    Dell R805 server, nice specs for ESXi server, but the local storage is limited.
    • 2 x sas (put them in raid 1, and it’s 136gb max)
    with openfiler hooked into it ( 2 x cat6 cross cable), the additional 256gb makes it much more flexible. (8 cpu cores, 8gb ram (upgradable to 32gb))

    observations:

    we had a guest win2k3 std server (running mssql 2k), it was reporting high cpu usage, periodically.
    once the shared storage went in, the cpu % has been more normal.
    it is likely due to low harddisk (for esxi swap) and overall memory used. (more memory needed = more swaps = more cpu usage)

    was reading the article:  “Cheap and quiet solution for a home-based ESX Server” [url]

    gonna give my props to HP workstation xw4000; we have gotten 3 units.

    • 4GB ram
    • intel core 2 duo (6300 @ 1.8ghz)
    • 4 x sata drives
    • 1 x Broadcom NetXtreme BCM5755 Gigabit (onboard)
    • dual head nvidia quadro
    • Win XP Pro

    ESXi 3.5 U2/ Openfiler v2.3 installs out of the box.  for a low cheap price of < S$600.

    and it runs so quiet….

    We have ESXi running on one of the machines, another one is running XP Pro (with VM Workstation, running a virtualised copy of Domain controller (win2k server). 3rd machine is a standby machine for a client’s project (part of support/ maintenance)

    and coming soon, an external esxi + openfiler machine, to look up to the ESXi server as shared storage.
