So I have two Dell R430's and a bunch of SAS disks (chassis to be procured) that I want to link to the two cluster nodes. I've already tried iSCSI but have SPOF issues with the SAN box (both Windows Storage Server and Synology) so looking at DAS to eliminate dependence on third party.
Lots of research but I'm not able to determine if all HBA/RAID controllers can handle dual controllers. Avago Syncro is basically what I'm after but not at the $7K asking price.
Am I correct in thinking most controllers will support dual hosts on the SAS link, I just need a backplane that is capable? Or do I need special SAS disks?
What's the verdict on the following:
Appreciate the feedback. Cheers

What's the verdict on the following:
- HBA or RAID controller (with external SF8088/644 connectors)
- Storage Spaces or RAID (for VM hosting)
- Is RAID possible with dual hosts?
Appreciate the feedback. Cheers
