E20-324 VNX Practice Exam Question - SnapView
Hello can you help me here with this question
A customer wants to add a SnapView snapshot to a 512 GiB LUN. Captured data shows that the LUN performs 600 random 4 KiB IOPs with a read/write ratio of 3:1.
What is the expected initial bandwidth at which data chunks will be written into the reserved LUN pool?

Each Random Write on the source cause a 64 KiB chunk to move to RLP
IOPs = 600 IOPs (450 reads and 150 writes)
=>Bandwidth = 150x64 = 9600KiB/s
= 9600/1024
= 9.375MiB
Hope this helps !!!
