Home -> Community -> Mailing Lists -> Oracle-L -> Re: Data Warehousing - RAID5 or RAID0-1
Hi,
We built a 4.3 TB data warehouse about a year and half ago. This was on
clarions and we had a combination of RAID 1, RAID 5 and RAID 10, depending
on the type of data that was being put on the devices.
Please let me know if you need more information.
Regards,
Madhavan
