I can't seem to build my own because I can't find the redundant sas controller for purchase by itself!!
---Sans Digital says theirs are provided by Areca, but I dont see them listed on their site.
---Raidinc has shared sas storage systems, but won't tell me who makes their controller.
---Dell says their controller is by LSI, but I can't find the controller on LSI's site.
I just want to build my own in a Norco 4224 case, what all am I missing?!?!
Redundant controller means there are two of them. Easy? No! because next you need a backplane that supports double wiring to the disks and your case doesn't. Anyway, if you can fix that: what OS will you use for the box?
Re: double wiring - Now that you mention it, that may be another hurdle. Could I put a little SAS switch in there? On paper it seems possible...
Re: OS - depends on the controller's requirements. Dell's and Sans Digital's use only the firmware on the controller itself as the "OS" which is really to say the firmware has a standard web interface via ethernet.
'what are you trying to use it for' might be the right question. On top you said 'shared storage' and something about two cluster nodes. At least the MD3200 is a direct attached storage. The redundant SAS-controllers are part of the servers and the MD3200 provides basically external disks. I don't see how you want to share this? If you want to share the disks you need to go for an IP-storage (NAS). That's what the case you mentioned is mad for. There is space for a MB plus SAS-controllers for the internal wiring plus ethernet controllers for the external wiring. With the right OS this will provide the server nodes with either dedicated iSCSI-Space and/or shared file system. Example: NX3300
