SRP supports multiple initiators like most other SCSI protocols.
Persistent reservations, access controls, etc. can be used to coordinate
activity between them. InfiniBand partitioning can also be used, but
SRP does not depend on it to keep initiators apart. How partitioning
gets used is a more global InfiniBand question, being solved by OEMs, OS
vendors, and InfiniBand management software vendors.
