A new data warehouse will be hosted on an existing 4-engine VMAX array. The database server
has 4 HBAs connected at 8Gb/s. Due to limited SAN switch ports only port 0 on each VMAX FA is
connected – also at 8Gb/s.
The workload is expected to require at least 1700MB/s of reads @ 128KB I/O size. It must
maintain performance in case of any major component failure in the host, switch or array. Assume
that the existing workload on the VMAX does not exceed 350MB/s per port. Also assume that the
ports can sustain up to 500MB/s without exceeding 70% utilization.
What is the best practice HBA to FA mapping to ensure the required performance of the data
warehouse?

A.
HBA0 -> Engine 3 FA ports HBA1 -> Engine 4 FA ports HBA2 -> Engine 5 FA ports HBA3 ->
Engine 6 FA ports

B.
HBA0 -> E0 FA ports HBA1 -> F0 FA ports HBA2 -> G0 FA ports HBA3 -> H0 FA ports

C.
HBA0 -> E1 FA ports HBA1 -> F1 FA ports HBA2 -> G1 FA ports HBA3 -> H1 FA ports

D.
HBA0 -> FA 7e0, 8e0, 9e0, 10e0 HBA1-> FA 5e0, 6e0, 11e0, 12e0 HBA0 -> FA 7h0, 8h0, 9h0,
10h0 HBA1-> FA 5h0, 6h0, 11h0, 12h0
