    RAI D arrangement on 8 bays servers

    Hi

    we have a 8 HD bays server, but need to keep one for /backup

    so now we have 7 bays empty, what is the best RAID setup?

    can I do a RAID10 with 6 drives?

    RAID6 with 6 drives maybe?

    for shared hosting, trying to max server

    Or how about you backup to an external server? Thus improving your DR policy by having the backups stored on a seperate server and allowing you the full 8 drives for your shared hosting server?

    For max performance I would do RAID 10 you can then use one disc for spare and the last for backup.

    If your controller supports it you can do a 7 disk RAID1E.

    I would do 6 discs in raid 10 and have one for spare, and one for the backup you mentioned.

    Are you going to use many small disks for the RAID? I mean, if you have 7 1TB hard drives (@ RAID 6 = 5TB), even the largest 3TB backup drive can't even contain a single copy of the monster RAID your setting up?

    I'd setup a RAID 10 and then partition it accordingly.

    I second RAID10 and a hot spare. This gives you redundancy and performance. Instead of doing a hot spare, you could also do RAID0 for your /backup with the last 2 drives out of your 8 drive array.

    You can do 6 hdds in RAID-10 + 1 spare drive + backup drive (like mentioned above).
    or you can do 4 hdds in RAID-10 + 2 hdd in RAID-1 (go with ssd for mysql) + 1 spare + backup drive

    Some RAID controllers support 1 SSD + 1 SAS/SATA in RAID-1, so the spare would replace the ssd if it fails. You can then order/ship a new sdd and replace the spare, if that makes any sense.

  14. supermicro 8-bay 2U chassis, such as SC825TQ series, comes with 2 extra fix-mount 3.5" bays on top of the 8x hot-swap bays. thus, you can configure the full 8x HDD RAID-10 from hardware RAID card, then just use the fixed-bays to install 3.5" backup drives connected to on-board SATA controller. additionally you can mount an extra 2.5" HDD in slim CD bay as well.

    6 Drives in raid 10, 2 drives in raid 1.

    No one else thought that was a good idea?

    em...6 in RAID10 and 2 in RAID1 seems perfect ;p

  18. hardware raid1 for "/backup"? seems to be a bit overkilling...

    if I was absolutely limited to 8 drives total, I would do 6x HDD RAID-10, 1x hot-spare for raid-10, 1x backup. this way, the backup can be any size of non-RE drive (even new 3TB green). if RAID1 for 7th/8th drives, they would have to be identical pair of RE/enterprise-class drives.

    best scenario is to use forth-mentioned SM SC825TQ chassis, then you can have total of 11 bays. perfect for 8x hot-swap 3.5" HDD hardware RAID-10, 1x 2.5" boot drive, 2x fix-mount 3.5" backup drives as software RAID0 or RAID1.
