Raid or No Raid?? 12x2tb

#1 Postby joebloggs » Apr 09, 2012 10:41 pm

If you have a server with say 12 x 2tb drives.

Anyone here just set each drive up as a seperate subdomain??

Would that workout okay if each drives data was backed up on a different machine?

How does this compare to raid 10?

How much faster/slower would the above set up be vs raid6?

Raid kind of worries me in that if you lose 2 drives with raid 10 you could lose your entire server data.

There must be a very good reason why everyone uses raid over lots of separate sub domains. Also say you have the nginx mod done, would you need to pay for 12 x nginx mods if the drives are all allocated to different subdomains?

i havent setup raid so cant comment, but yes if you use nginx mod you will have to pay for all 12 sub domains , but cost is less for servers on same machine

no raid = waiting for data to be lost on a drive failure

i would go with raid10, gives good performance and data is safe

Got the answer already , its not needed to buy each time the nginx mod.

servers without raid and multi hdd needs multi subdomains on multi hdd in that scene we have to pay per sub domain / server for nginx mod , in my case i had my server with 4 hdds / 4 servers/subdomains but cost is less compared to physical servers

Thanks for you help. If we had a back up server with 12 drives though this would be okay right?

With raid 10 if 2 drives fail on same build then the entire 12 drives are lost though right? that is kind of worrying for us.


What about raid 6 ? this can have 2 drive failure i hear and still be okay?

Also about the 12 seperate subdomains one for each drive, would that not be quite a fast solution? without the worry of losing entire array?

how much time would it take to transfer 2TB from your backup server ? can you afford such a downtime ?

chances of that are extremely rare, raid10 is safest; but its not an alternative to offsite backups

raid 6 has poor write performance & any 2 drive failures can mean you loose all data

as i said previously, it depends if you have a offsite backup & the amount of downtime you can afford

Just to add my point to the discussion:

do not forget that Raid 5/6/10 are usually found on high end controllers, that will surely provide an option to configure some drive as hot spare, and some monitoring software to instantly send an email when a drive fail or has an anomaly.

Bye.
