Hello Nelson,

of course you can configure 45 disks in a raid 5, but when I`m talking about the AX 4/5I I recommend to use 5 disks (4+1 , the 1 is the parity drive which is striped over the raidset) or 9 disks(8+1) in a raid 5, please also consider possible rebuild times, if a drive fails. I personally think, even with a hotspar drive , its a risky config due to high rebuild times..... (my opinion, of course)
To be more specific I assume you want to use the SATA drives as file or backup to disk scenario ? If not can you explain what are you intending ? Its important for a good lun and raid design, please also be aware that sata drives provide not the same IO`s and speed than a sas drive.
Can you pass a litte bit more infos if possible ?
Thks alot

Marcus

Argh,

sry forgot to mention that you can create a metalun also, you create several raid 5 groups and create a big virtual lun of the raid groups, this gives you the advantage to have a big lun instead of several small luns, but you loose some diskspace and the perfromance is a little bit slower than a traditional created LUN.

a HOWTO of creating metaluns is available in your AX manual

Cheers

Marcus

Hi,

also there is a rule depending on number of disks in a raid group.
Never more than 16 drives per raid group because the risk computationally gets to high that more than 1 drive could fail a the same time. BTW: this is a official rule from EMC.
If that happens you are in world full of s"§$ !

Hi Marcus. Thank you for the information. This storage is oriented to an image system. At this time, the image system provider, could tell me if the system can manage more than one volume to save files. I appreciate very much, the options you gave me. Greetings.
