Hello,
My reverse calculation shows that value of a* N = 101.8.
Explanation:
6.4TB is approximately 7036874417766 bytes
There are 288 5-min intervals in the 24-hour period.
1,000,000 * a * N * 120 * 2 * 288 = 7,036,874,417,766
a * N = 101.8
My educated guess is that N is 400 and a is the compression factor (~0.25 in this case).
HTH
Thx
Alex
