Dot Hill Systems SANnet II 200 FC Array, SANnet II 200 SATA Array, SANnet II 200 SATA SE Array

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.
