Chapter 2 Underlying Concepts and Practices 11
Caution – In FC and SATA configurations with large drive capacities, the size of the
logical drive might exceed the device capacity limitation of your operating system.
Be sure to check the device capacity limitation of your operating system before
creating the logical drive. If the logical drive size exceeds the capacity limitation, you
must partition the logical drive.
TABLE 2-3
shows the usable capacity of the drives available in Sun StorEdge 3000
family arrays.
Note –
The 250 Mbyte of reserved space on each drive used for storing controller
metadata is not included in this table, since it is not available for storing data.
TABLE 2-4
shows the maximum usable storage capacity for Sun StorEdge 3510 FC
arrays and Sun StorEdge 3511 SATA arrays, using the maximum number of
expansion units, fully populated with the largest currently available drives.
Note –
Be sure to check the latest release notes for your array to see additional
guidelines or limitations for large configurations.
Each logical drive can be partitioned into up to 32 separate partitions or used as a
single partition. Partitions are presented to hosts as LUNs.
