SATA Storage Enclosures (FS4100 and FS4500) Both I/O modules use SFP connectors, and 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 SATA Storage Enclosure uses a SATA interface to the hard disk drives. This SATA interface supports data rates of 1.5 Gb/sec. The Adaptec FS4500 Storage Enclosure supports RAID levels 0, 1, 0+1, 3, 5, 10, 30, and 50. SATA Cables Hosts communicate with the Adaptec SATA Storage Enclosure through FC cables. Optical cable lengths supported: ■ Minimum length is 2 meters for all data rates. ■ Maximum lengths at 2 Gb/sec are 150 m of 62.5 µm cable and 300 m of 50 µm cable. ■ Maximum cable lengths at 1 Gb/sec are 300 m of 62.5 µm cable and 500 meters of 50 µm cable. ■ Maximum copper cable lengths are 6 m with a passive SFP connector and up to 12 m with an active SFP connector. Note: Copper cables and optical cables are available for sale on the Adaptec Web site at www.adaptec.com. SATA Configurations Each FS4100 and FS4500 Storage Enclosure I/O module can be connected to up to two hosts. The I/O modules can be used to form both single and dual SATA configurations. Single SATA Configurations A single Storage Enclosure has one I/O module, either FS4100 (JBOD) or FS4500 (RAID) and can be connected to one or two hosts. Note: An I/O blank must be used in a single I/O configuration to maintain proper airflow and cooling. 5-3

SATA Storage Enclosures (FS4100 and FS4500)
Both I/O modules use SFP connectors, and 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 SATA Storage Enclosure uses a SATA interface to the
hard disk drives. This SATA interface supports data rates of 1.5
Gb/sec.
The Adaptec FS4500 Storage Enclosure supports RAID levels 0, 1,
0+1, 3, 5, 10, 30, and 50.
SATA Cables
Hosts communicate with the Adaptec SATA Storage Enclosure
through FC cables. Optical cable lengths supported:
Minimum length is 2 meters for all data rates.
Maximum lengths at 2 Gb/sec are 150 m of 62.5 μm cable and
300 m of 50 μm cable.
Maximum cable lengths at 1 Gb/sec are 300 m of 62.5 μm cable
and 500 meters of 50 μm cable.
Maximum copper cable lengths are 6 m with a passive SFP
connector and up to 12 m with an active SFP connector.
Note:
Copper cables and optical cables are available for sale on
the Adaptec Web site at
www.adaptec.com
.
SATA Configurations
Each FS4100 and FS4500 Storage Enclosure I/O module can be
connected to up to two hosts. The I/O modules can be used to form
both single and dual SATA configurations.
Single SATA Configurations
A single Storage Enclosure has one I/O module, either FS4100
(JBOD) or FS4500 (RAID) and can be connected to one or two hosts.
Note:
An I/O blank must be used in a single I/O configuration
to maintain proper airflow and cooling.
