best way to setup my system raid / page file
Posted on 2011-09-20
I would like to get people's opinion about my proposed system setup. I would like to know how best to use my drives and setup my page filing for system performance.
I have a Dell Precision 690
a 64 bit machine
one dual-core Xeon 5100
4GB of RAM running in quad-channel2 architecture DDR2 Fully Buffered DIMM 533 and 667MHz ECC
I will be installing 32-bit XP Pro
I have four hard drives to install. Two new 80GB WD Raptors which are 10k rpm. And two used 80GB 7200 rpm seatgate drives. They are all SATA drives.
My system has a built in RAID card. LSI SAS 5 (SAS1068). It can handle RAID 0 and RAID 1.
I was initially planning to use two of the drives in RAID0 configuration and to install the OS there. But I have been informed that this would not bring any performance gain at all and would increase the chance of error (I would double the chance of a failed hard drive and system crash).
What about this plan….
Skip raid configuration altogether
Install the OS on one of the new 10krpm drives ' without partition the drive.
Then install the second 10k rpm drive and install apps on that drive.
Install the two used 7200 rpm drives. Don't partition them. Use them only as page file / swap file locations. Never install any data on those drives.
What would you recommend for the page file settings? I would guess that I should set one page file on C, windows managed, for memory dumps or whatever. Then I should use max/min setting for the two page files on the 7200 drives. Based on the fact that I will always have 4gb ram what would you suggest for the min/max settings.
Note… I don't need to use any of those drives to store personal data. I use large externals for that.
I don't care too much about raid for recovery purposes. I do care, but not tremendously – I care far more about system performance.
