Note –
Although the products are very similar in appearance and setup, the
configurations have very important differences. While the FC array can be used for all
applications, the SATA and SATA SE arrays cannot. Inappropriate use of the SATA
arrays in applications for which the FC array was designed might result in loss of data
and/or loss of data access.

Applications
Best suited for
production applications
where the superior
features of FC technical
characteristics and
performance are
required. This includes
online applications such
as:
• Database
• Decision support
• Data warehousing
• Electronic commerce
• Enterprise resource
planning
• Messaging, file, and
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.
This includes 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
