Comparison of FC, SATA, and SATA SE Arrays

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
