I'm contemplating the next restructuring of my medium-size storage. It's currently about 30TB, shared via AoE. My main options are:
- Keep as is. It can still grow for a while.
- Go iSCSI. currently it's a little slower, but there are more options
- Fibre Channel.
Personally, I like the price/performance of InfiniBand host adapters, and most of the offerings at Supermicro (my preferred hardware brand) have IB as an option.
Linux has had IPoIB drivers for a while; but I don't know if there's a well-known usage for storage. Most comments about iSCSI over IB talk about iSER, and how it's not supported by some iSCSI stacks.
So, does anybody have some pointers about how to use IB for shared storage for Linux servers? Is there any initiator/target project out there? Can I simply use iSCSI over IPoIB?
