Hi I am studying for E20-324 and I'm struggling with this question as I can not match my answer with the provided answers.

Here is the question:

Your customer wants to use a VNX system at an unmanned DR site. The system will be used exclusively as a secondary MirrorView/A system, and it is capable of performing 60,000 LUN IOPs in this role. The primary system is also a VNX.

If the primary image workload consists of 1 KiB random IOs with a R/W ratio of 3:1, what is the maximum bandwidth required for the link between the VNX systems?

240 Mb/s

120 Mb/s

360 Mb/s

600 Mb/s

I tried to answer the question this way:

Each update to secondary image cause 5 + 1 = 6 I/O

60,000 / 6 = 10,000

10,000 * 1 Kib = 10,000 Kib

Which is not in the answers , can you please help me to sort this out?

Thanks,

Golnaz
