| Question ID 21469 | 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:
|
| Option A | Use just LVM
|
| Option B | Use RAID1 over LVM
|
| Option C | Use LVM over RAID5
|
| Option D | Use LVM over RAID1
|
| Option E | Use RAID5 over LVM
|
| Correct Answer | C |
Explanation 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.
