For 250GB Drives: 2

a If you select By quantity, you can create between 1 and 80

cartridges per RAID set. The capacity decreases the more tape

cartridges you create. For example, if you select 1 tape cartridge

per RAID set, each cartridge has approximately 1.7 TB (1.45 TB

for the second RAID set) in capacity. If you select 80 tape

cartridges, each cartridge has 20 GB capacity.

b If you select By capacity, you choose between 20 and 1700 GB (43

and 1450 for second RAID set) capacity per cartridge. The

number of cartridges decreases with higher capacity per

cartridge. For example, if you select 20 GB per cartridge, the

number of cartridges per RAID set is 80. If you select 1700 GB per

cartridge, the number of cartridges per RAID set is 1.

For 400GB Drives: 2

a If you select By quantity, you can create between 1 and 80

cartridges per RAID set. The capacity decreases the more tape

cartridges you create. For example, if you select 1 tape cartridge

number of cartridges decreases with higher capacity per

Note: The capacity estimates mentioned in the examples above

assume a RAID 5 configuration on the storage array with

“global hot” spare. If a “global hot” spare is not used, the

total capacity is increased by 250GB. If two “global hot”

spares are used, the total capacity is decreased by 250GB.
