The ARC-4036 SAS-to-SAS JBOD enclosures provides a compact external storage chassis capable of accommodating up to 8 6Gb/s, Serial-Attached SCSI (SAS) drives or 6Gb/s Serial ATA (SATA) drives. The Areca SAS expander module is based on the LSI 28-port LSISAS2x28 expander IC, SAS-2 chip which features 28 x 6Gb/s ports and 6G/3G multiplexing, SAS 2.0 zoning, self-configuration, table-to-table routing, and an integrated PPC processor for SES-2 and enclosure management support. Each ARC-4036 compact tower JBOD connects to the host system through two 4-lanes SAS connectors (Host In) and two 4-lanes SAS connectors (Exp. Out) to the next SAS-to-SAS JBOD enclosure. It is used to enhance the ARC-8040 RAID subsystem by allowing support for more than 8 internal hard disk drives. Configuration and environmental information is accessible either via in-band (SES-2 over SMP) or out-of-band serial port.
