P4500 Write cache disabled in BIOS

P4500 Write cache disabled in BIOS

Hi guys,
I was setting up a couple of P4500 storage nodes and noticed that write cache in the BIOS was disabled. Shouldnt this be on to help performance?
Any thought would be great.
Thanks
Dougie

Re: P4500 Write cache disabled in BIOS

Check in the hardware information log in the CMC to see if everything is correct. We had a few DL320s machines that the battery cable to the cache had come undone and caused things to slow down a bit. Your information log should show something like this:

Controller/Cache Items
  Card 1
    Model Smart Array P400
    Serial Number *********
    Cache Status normal
    Battery Status normal
    Cache Enabled Statusnormal
    Cache Size 512MB
    Hardware Version Rev B (Not Exact)
    Firmware Version 7.08 (Not Exact)
    Driver Version N/A
    Voltage N/A
