0x9h3 Posted February 26, 2018 Posted February 26, 2018 Is a hardware raid better to use in a production environment ?
bwestlake Posted February 26, 2018 Posted February 26, 2018 I have always suggested using raid 6 with a hot spair as this way a drive can fail then automatically rebuild, and you just have to replace the failed drive with a new one which will then be the hot spair. Yes you do loose three drives out of the array but you could use raid 10 which then looses half.
ricki Posted February 26, 2018 Posted February 26, 2018 Yes hardware raid is better and faster if you have software raid and you have problem with is it can stop working
0x9h3 Posted February 26, 2018 Author Posted February 26, 2018 (edited) How recoverable is data if you’re using software raid? For example, if you’re using software raid 1 on D drive using two drives and the C windows drive failed. How easily can you recover the data on D? Edited February 26, 2018 by 0x9h3
Norphy Posted February 26, 2018 Posted February 26, 2018 RAID1 is mirroring (the OP had RAID 0 and 1 the wrong way around) so if a drive in any RAID 1 array fails, be it hardware or software, the other one will take over. That will only protect against hardware failure however. If the data gets corrupted for another reason the data will be corrupted on both drives. RAID is not a backup. If you’re asking about a drive railing in a striped array (RAID 0), you’re boned. The data is gone which is why you never put anything you want to keep on a RAID 0 volume.
Norphy Posted February 26, 2018 Posted February 26, 2018 Yes hardware raid is better and faster if you have software raid and you have problem with is it can stop working This statement is inaccurate at best. Depending on the RAID type, a hardware array may not be any faster than a software one, the simpler RAID types where there are no parity calculations especially. In terms of resiliency, in my experience hardware RAID is no more and no less reliable than software RAID. I’ve had hardware RAID controllers do... interesting... things before and with software RAID, there is one less controller to fail!
TwistedHelixis Posted February 26, 2018 Posted February 26, 2018 (edited) All my primary schools are raid 10. 5 to 10 years ago they were raid 5 but had a few issues after replacing faulty drives so went raid 10, never looked back Edited February 26, 2018 by TwistedHelixis
