HP Surestore Disk Array 12h and FC60 - Manual (Page 100)

100 Recommended Disk Array Configurations
Total Disk Array Capacity
The total capacity provided by the disk array depends on the number and capacity of disks
installed in the array, and the RAID levels used. RAID levels are selected to optimize
performance or capacity.
Table 6 lists the total capacities available when using fully loaded disk enclosures
configured for optimum performance. Table 7 lists the same for optimum capacity
configurations.
The capacities listed reflect the maximum capacity of the LUN. The actual storage capacity
available to the operating system will be slightly less, as some capacity is consumed when
binding the LUN and creating the file system.
