Customer requirements call for a SnapView snapshot to be made of a clone prior to
resynchronization. The source LUN is 512 GiB, and performs 550 random reads/s and 10 random
writes/s of 4 KiB. The clone will be fractured every 10 minutes, and resynchronized after the
snapshot is started.
How many COFWs will be performed each time the clone is resynchronized?
A.
24,000
B.
12,000
C.
36,000
D.
48,000
512GiB LUN = 512 Blocks = 256KiB
256 * 10 RANDOM writes per second * (10 mins * 60 Seconds) = 1536000
1536000 / 64KiB Chunks – NOTE: if sequential then it’s 64/(IO block size).
