The correct answer is A. Local: 3,200 IOPS; Remote: 1,300 IOPS. See the full explanation below for the reasoning.

Question

A customer has two VNX systems:

  • At the local site, a VNX capable of performing 10,000 LUN IOPS
  • At the remote site, a VNX capable of performing 7,000 LUN IOPS

At the local site, application LUNs to be mirrored to the remote site perform 2,000 random 4 kB IOPS, with a R/W ratio of 4:1. At the remote site, application LUNs to be mirrored to the local site perform 1,200 random 8 kB IOPS, with a R/W ratio of 3:1. The utilization of both systems must be 70% or lower. MirrorView/A will be used to replicate the data. How much throughput can be performed by other applications at the local and remote sites?
