Connecting hosts to the DS5100 and DS5300 iSCSI ports

The DS5100 and DS5300 supports redundant connections to the host with iSCSI
HBAs or iSCSI software initiators. To ensure full protection against the loss of any
path from the host servers, always use redundant host connections by connecting
each host to the appropriate Ethernet switches with connections to both RAID
controllers A and B iSCSI host ports. To connect an iSCSI host adapter to the
DS5100 and DS5300 RAID controllers, complete the following steps:
1. Connect the Category 6 Ethernet cables from the RAID controller iSCSI host
2. Connect the Category 6 Ethernet cables from the iSCSI host bus adapter ports

or the Ethernet ports of the server using an iSCSI software initiator to the same
Ethernet switch or one that is in the same Ethernet network as the RAID
controller iSCSI host ports.
