SNC Description
The SNC 4500 and SNC 4501 are Gigabit Ethernet (GbE) to SCSI Storage Networking Controllers that
enable iSCSI protocol support for your Scalar 100 and Scalar 24. Visit
www.adic.com to see a list of drive
types currently supported by the SNC 4500 and SNC 4501.
The SNC 450x
1
includes two Ethernet data ports, an Ethernet management port that may be used as a data
port, a serial management port, and two SCSI ports. The SNC 4500 has a 100-240V 50-60Hz auto sensing
power supply. A US and European power cable are provided. The SNC 4501 receives power directly from
the Scalar 24.
The SNC 4500 is installed externally to the Scalar 100 in standard 19" racks or free standing near the library.
The SNC 4501 is integrated into the Scalar 24.
SCSI Ports
The two SCSI ports use independent buses and connect storage devices into the iSCSI SAN. The ports are
Ultra 3 LVD/SE SCSI buses with a “P” interface and VHDCI connector. These ports are terminated
internally. They provide 160 MB/sec maximum throughput, and are downwardly compatible with all forms
of single-ended SCSI. For the position of the SCSI ports on the SNC 4500, see
Figure 1 . For the position
of these ports on an SNC 4501, see Figure 2 .
1. This document uses the term SNC 450x to refer collectively to the SNC 4500 and the SNC
4501.
