To install additional switches, you must determine the ideal ISL ratio. Which ISL ratio range
is recommended for less I/O intensive application requirements (less than 70 MB/s at 2
Gb/s, less than 140 MB/s at 4 Gb/s, less than 280 MB/s at 8 Gb/s)?

A.
3:1 to 1:1

B.
1:1 to 3:1

C.
15:1 to 7:1

D.
7:1 to 15:1

Explanation:
Recommended core-edge fabric ISL ratios
I/O workload Recommended ratios
Higher I/O data intensive application requirements (greater than 70 MB/s at 1:1 to 3:1 2 Gb
/s, greater than 140 MB/s at 4 Gb /s, greater than 280 MB/s at 8 Gb /s) Lower I/O data
intensive application requirements (<70MB/s at 2 Gb / s, <140 7:1 to 15:1)
