P: n/a
Hi,

We are planning to host our database on Linux. Can any one share
experiences on the following aspects:

1. Is RAID5 better or RAID 0 or 1 better ? (we have thosuands of
queries running per day)
2. Is hardware disk controller better or LVM better?
3. any particular machine configuration to consider
Thanks for sharing the knowledge.

Not AGAIN!!!!!!!!!!!!!!!
1 Raid 5 is inferior for any writes, and you shouldn't have your
online redologs on RAID 5
2 It depends. Software RAID will be slower, but you are more flexible
with respect to actual disk configuration
3 We don't market hardware here.

There is no way to answer your questions without information of how
you plan use your database (i.e. read/write ration, DB size and so
on).
