P9500 Disk Array details:
◦ LDEVs = 1703
◦ PORTs = 96
◦ Dkc_Collection_frequency = 300 seconds (5 * 60)
◦ Ldev_Collection_frequency = 600 seconds (10 * 60)
◦ Port_Collection_frequency = 600 seconds (10 * 60)
Free_Space on P9500 Disk Array = [(86400/600) *1703 * 0 .0002] + [(86400/ 600)
* 96 * 0.00008] + [(86400/300) * 0.0002] = 49.04 + 1.1 + 0.05 = 50.19

◦ Ldev_Collection_ frequency = 900 seconds (15 * 60)
◦ Port_Collection_ frequency = 600 seconds (10 * 60)
Free_Space on XP24000 Disk Array = [(86400/900) *2554 * 0 .0002] + [(86400/
600 ) * 32 * 0.00008 ]+[(86400/300) * 0.0002] = 49.03 + 0.36 + 0.05 =
