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?

Jaloma

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 !!!
