Click on the calculator icon in the upper left-hand corner. A customer has a 2 TiB LUN which will be mirrored with MirrorView/S. Analyzer shows the current workload to be 500 8 KiB IOPs with a R/W ratio of 3:1. The customer requires that the mirror should resynchronize within 2 hours if fractured for 10 minutes or less. How much bandwidth is required to meet customer requirements?
A.
10 Mb/s
B.
20 Mb/s
C.
54 Mb/s
D.
114 Mb/s

1 – Host: 125w * 8KiB=1000KiB -> 10000 Kb-> 10Mib;
2 – Fractured(2TiB->1024 KiB granularity): (10m * 60s * 125w * 1024 KiB) /1024 KiB = 75000 MiB;
75000 MiB/(2H * 3600s)= 10.4MiB/s -> 104 Mib/s
3 – Total:104 Mib/s + 10Mib =114 Mib/s
