Solaris multipath has two modes, round-robin and "Logical Block" mode
Add "Logical Block" support to our existing Active/Active and Active/Read modes
It divides the devices up into stripes of 2^x bytes, where x is configurable
All sectors in the same stripe are always accessed via the same path (if it is up).
This can improve performance by hitting the same controller for sequential reads, and taking advantage of read-ahead and cache.
