A server has three disks of 80GB each and must manage a database with 4 million records of
30KB each. The best configuration for this server, with the criteria being performance,
configurability and flexibility, is:
A.
Use just LVM
B.
Use RAID1 over LVM
C.
Use LVM over RAID5
D.
Use LVM over RAID1
E.
Use RAID5 over LVM
Explanation:
RAID1 would not be performance enhancing (Mirroring), as would the default LVM (linear). So use
a RAID5 for redundancy and performance and use LVM for added configurability and flexibility
A striped LVM only would work too, I guess, if you need no redundancy at all.
