One Unix server and one Windows server share the front-end ports CL1-A and CL2-A of a VSP E590 system. What are two requirements to separate the I/Os of the servers? (Choose two.)

Question

Options

• ABoth servers must be registered in two different Host Groups.
• BPort security must be enabled on both ports.
• CThe Universal Volume Manager license must be installed.
• DTwo cache partitions must be created on the VSP for the servers.

• A
  77% (20)
• C
  15% (4)
• D
  8% (2)

Explanation

Separating I/O between a Unix and Windows server on shared front-end ports requires Host Groups (A) and Port Security (B) because they work as a complementary pair: Host Groups perform LUN masking by defining which volumes each server is allowed to see, while Port Security enforces those Host Group definitions by blocking any unregistered host from accessing the port at all. Without Port Security enabled, the Host Group boundaries are not enforced on the port, and without separate Host Groups, there is nothing meaningful to enforce - both must be active together for true I/O isolation.

Why C is wrong: The Universal Volume Manager license is for virtualizing external storage from third-party arrays into the VSP - it has nothing to do with separating host access on local ports.

Why D is wrong: Cache partitions (Virtual Partition Manager) allocate cache memory between workloads for performance isolation, but they do not restrict which volumes a server can see or access - they don't enforce I/O separation between hosts.

Memory tip: Think of it as a door lock analogy - Host Groups are the key list (who gets which rooms), and Port Security is the lock on the door (that actually checks the list). You need both the list and the lock for real separation.
