What is a potential downside of having more than four paths per datastore?

A.
limits the storage protocols

B.
increases storage latency for VM

C.
limits the path selection policies

D.
limits the number of LUNs per host

Explanation:
While using more than the required number of paths restricts the number of LUNs you can present to a host, it
may also affect host resources such as CPU cycles and also every path from a host requires an initiator record
and there may be a limit to the number of initiators per storage system.
Large numbers of paths i.e in excess of 4 per host may be required in environments where bursts of I/O from
other hosts sharing the storage system ports are unpredictable and severe, for example boot storm scenarios
where 8 paths per host might be plausible.
