Question
A new data warehouse will be hosted on an existing 4-engine VMAX array. The database server has 4 HBAs connected at 4Gb/s. Due to limited SAN switch ports only port 0 on each VMAX FA is connected-also at 4Gb/s. The workload is expected to require at least 2300MB/s of reads at 128KB I/O size and 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 100MB/s per port and assume that the ports can sustain up to 300MB/s without exceeding 70% utilization. What is the minimum number of FA ports needed to spread the workload evenly across all 4 VMAX engines and meet the above performance requirements?
Options
- A16 FA ports, 4 per engine
- B12 FA ports, 3 per engine
- C16 FA ports, 4 per director
- D24 FA ports, 3 per director
