Click on the calculator icon in the upper left-hand corner. 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 total primary image workload consists of 1 KiB random I/Os with a R/W ratio of 3:1, what is
the maximum bandwidth required for the link between the VNX systems?
A.
240 Mb/s
B.
120 Mb/s
C.
360 Mb/s
D.
600 Mb/s
I’ve been looking through material and can’t seem to find the formula to help solve this, please can someone post it up? thanks

5 CoFW for MW/A activity therefore it is:
60,000 / 5 = 12,000 * 1KiB/s (however transfer rate = 2KiB) * 2KiB = 24,000 KiB/s
24,000 KiB/s * 10 = 240,000 Kb/s = 240 MB/s
