Home -> Community -> Mailing Lists -> Oracle-L -> Fwd: RE: RAID or NOT to RAID?
Hi DBA's,
I hope I'm not opening a can of worms, but I'd like your feedback on the
issue of using RAID 5 on NT 4.0 with Oracle 8.0.5.
I have worked with Solaris and RDBMS before switching to this job using the
NT platform. So I'm having to adjust and revisit the issues that was of
concern on the unix platform.
The NT and RAID configuration does not allow you to locate your datafiles
and logs on seperate specific disks. Also I don't know if the use of raw
devices on NT is possible if RAID 5 is enabled.
I've read about the performance loss inherent with RAID 5 because of the
writes to the parity disk.
I'd like to find out more about these issues and how you all are dealing
with them on the NT 4.0 platform?
Thanks in advance for your time.
Regards,
