Twenty 300GB data drives:
300,000,000,000 * 20 = 6,000,000,000,000
6,000,000,000,000 / 268,435,456 = 22351.74 extents
Two extents per data drive reserved for quorum disk use:
22351.74 – 40 = 22311.74
Five extents reserved per pool for future use:

22311 – 5 = 22306
.74 of an extent not available since less then a full extent:
268,435,456 * .74 = 198,642,237
