SATA Storage Enclosures (FS4100 and FS4500)
Dual SATA Configurations
A dual Storage Enclosure has two FS4100 or two FS4500 I/O
modules, and can be connected to one, two, three, or four hosts.
Note:
You cannot include Adaptec FS4100 and Adaptec FS4500
I/O modules together in the same Storage Enclosure.
Dual SATA configurations provide a redundant controller and
make better use of the available FC front-end bandwidth. The
redundant controller provides data access to more hosts and adds
the security of a second controller for data access.
summarizes the supported single and dual SATA
configurations. (For example, a single SATA configuration can
include one FS4100 or one FS4500.)
Flexibility and Limitations
■
The FS4500 RAID single controller configuration can be
upgraded to dual controllers.
■
The FS4100 JBOD single I/O processor configuration can be
upgraded to dual processors.
■
All SATA systems with an FC interface at the front end require
SFP transducers, either copper or optical. (Copper cables with
SFPs built into them are available.)
■
Dual SATA RAID and JBOD configurations require drive
carriers with MUX cards installed.
■
The FS4050 single SATA JBOD configuration does not require
drive carriers with MUX cards installed.
