The SANnet II 200 FC array is a next-generation Fibre Channel storage system 
designed to provide direct attached storage (DAS) to entry-level, mid-range, and 
enterprise servers, or to serve as the disk storage within a storage area network (SAN). 
This solution features powerful performance and reliability, availability, and 
serviceability (RAS) features using modern FC technology. As a result, the SANnet II 
200 FC array is ideal for performance-sensitive applications and for environments with 
many entry-level, mid-range, and enterprise servers, such as:
Internet
Messaging
Database
Technical
Imaging
The SANnet II 200 SATA and SATA SE arrays are best suited for inexpensive 
secondary storage applications that are not mission-critical where higher-capacity 
drives are needed, and where lower performance and less than 7/24 availability is an 
option. These include near-line applications such as: 
Information lifecycle management
Content addressable storage
Backup and restore
Secondary SAN storage
Near-line DAS storage
Static reference data storage
It is possible, though not always desirable, to combine both FC expansion units and 
SATA expansion units connected to a SANnet II 200 FC RAID array. For instance, you 
might want to use two SANnet II 200 SATA expansion units for near-line backup and 
archival storage while the Fibre Channel drives in your RAID array and other 
expansion units are used for real-time, mission-critical information processing and 
input/output (I/O) operations.
For an example of such a configuration, refer to the SANnet II 200 FC and SATA Array
