Dual-path with Cascaded JBOD2000S3SP

Dual-path to a single-domain provides tolerance of cable failure. Two single-port JBOD2000S3SP systems

are cascaded with a mini-SAS cable between each “B PRI” SAS port, and a controller connects to each “A PRI”

SAS port with two mini-SAS HD cables. Any mini-SAS HD cable failure will not stop the data transfer between

the host and two JBOD2000S3SP. Both SAS and SATA drives support this configuration.
