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.

Note – For information about the maximum usable storage capacity for the SANnet II 200 FC, SATA, and SATA SE arrays, refer to the SANnet II 200 FC and SATA Array Best Practices Manual.

1.1.3SANnet II 200 FC, SATA, and SATA SE Array Configurations

The FC, SATA, and SATA SE arrays can be used in the following configurations:

■Single-controller configuration. A RAID array can be configured with a single controller in a non-redundant configuration.

■A RAID array with two controllers. A RAID array can be configured with two controllers to provide full redundancy.

■An expansion unit. An expansion unit consists of a chassis with disk drives and I/O expansion modules. The expansion unit does not include an I/O controller module. The expansion unit connects to and is managed by a RAID array. The SANnet II 200 SATA Special Edition (SE) does not support expansion units.

■A Just a Bunch of Disks (JBOD) array. The JBOD array connects to, and is managed by, a host server. Only the SANnet II 200 FC JBOD is supported.

See Appendix B for detailed information about using SANnet II 200 FC JBOD arrays.
