| Why don't you recommend using the raid provided by the controller |
| 6 |
| (SATA)? |
| 7 |
| |
| 8 |
| Is it also the same for an HP Proliant with a Smart Array? |
| 9 |
|
| 10 |
ok |
| 11 |
i'm just telling you my personal opinion |
| 12 |
|
| 13 |
if you have sata controller which has software raid on it, it usually |
| 14 |
means that controler has propietary implementation of raid in its bios |
| 15 |
if you are running linux, you can use linux software raid which i find |
| 16 |
much better because: |
| 17 |
|
| 18 |
- - no propietary format, this may be not an issue with raid1, but with |
| 19 |
raid0,4,5 you may be unable to replace broken controller by a |
| 20 |
different one (different type) |
| 21 |
|
| 22 |
- - raid1 -> linux software raid can operate on partitions, not only on |
| 23 |
the whole drives |
| 24 |
with 'two hdd in raid1' setup it means that you can have two swap |
| 25 |
partitions on both drives; and rest of the drives partitioned and |
| 26 |
paired in raid1 volumes; |
| 27 |
with sw raid controller you would have to put swap on raid which is |
| 28 |
not recommended |
| 29 |
|
| 30 |
- - linux software raid is much more flexible; if you read howto, the |
| 31 |
section about installing linux on a software raid1 without a need for |
| 32 |
another hard drive and without requiring your favourite distribution |
| 33 |
to provide you with all necessary tools on the installation cd, you |
| 34 |
will see why |
| 35 |
this would be impossible with mose sw raid controllers |
| 36 |
also converting an existing system into raid1 system, etc ... |
| 37 |
|
| 38 |
but this is just my humble opinion |
| 39 |
|
| 40 |
regards, |
| 41 |
