Technical Specifications
Serial ATA Interface
The Adaptec SATA Storage Enclosure supports a point-to-point,
SATA interface. The interconnect has controlled impedance
(50 ohm single-ended, 100 ohm differential) supporting the 1.5 Gb/
sec data rate and allows expansion to 3 GB/sec. The interface
complies with the guidelines issued by the SATA/High Speed
SATA specification, version 1.
SATA I/O Modules
The Adaptec SATA Storage Enclosure has two I/O modules
available--the FS4100 and the FS4500.
Both I/O modules have two connectors to either connect hosts or
to daisy chain to additional enclosures. Both the FS4100 and FS4500
modules use SFP connectors. They will accept either a copper SFP
connected to a copper cable, or an optical SFP connected to an
optical cable with LC connectors. The cable interface must be a
standard FC cable, so the end that connects to the host is purely
dependent on the host HBA connector selection.
The Adaptec FS4500 supports RAID levels 0, 1, 0/1, 3, 5, 10, 30, and
50.
SATA Cables
Hosts communicate with the Adaptec SATA Storage Enclosure
over FC cables. The optical cable lengths supported are per the FC
channel industry specification. The minimum length is 2 meters for
all data rates. At 2 Gb/sec data rates, the maximum lengths are 150
meters of 62.5 µm cable and 300 meters of 50 µm cable. At 1 Gb/sec
data rates, the maximum cable lengths are 300 meters of 62.5 µm
cable and 500 meters of 50 µm cable. Maximum copper cable
lengths are 6 meters with a passive SFP connector and 12 meters for
an active SFP connector.
SATA Configurations
Each FS4100 and FS4500 module can be connected to up to two
hosts. The modules can be used to form both single and dual SATA
configurations.
