We are using HP Blades with RIAD 1 for our Citrix Servers on Windows Server

partioned the RAID 1 into two partitions and stuck the page file, temp
directories and programs on the second partition?
Test it.
Also, consider if you would get better performance by using SCSI vs
SATA, and by using a RAID controller with a Read-Write cache, and the
size of that cache.
If not has any one used a
RAMDISK for this? Or is their an argument for eliminating RAID 1 altogether
and just put the page file, temp directories on the second hard drive
Don't try to be clever. Stick to the KISS principle. The 4th S is VERY
important - If you (K)eep (I)t (S)imple, then the (S)tupid idiot that
tries to fix or improve things when you're on vacation won't screw up
what you've already done.
(better performance and more disk space). Since I have a boat load of blades
where is the risk?
The risk is that if you don't do a RAID 1 on the blades like everyone
else does, someone somewhere will question the logic of it, and either
will mess up when it goes wrong, or will try and be clever and make it
go wrong.
So I lose one or two drives a year on my servers and each
time 50 - 60 users get kicked off. heck! I do that accidently at least once
a year!? Managment might not buy that argument but If the performance gain
is significant then it's worth it. Your thoughts?
Just do the (bleedin) obvious. It's not worth the hassle of doing the
work required to measure the performance benefit of anything other
then the obvious, and non-obvious setups are prone to human error,
which is har less predictable than hardware errors.
I used to do server support for HP - Hardware is easy - you know what
you're dealing with and it behaves predictably. Sysadmins however are
another matter...
