DAS (Direct Attached Storage) Connection to Two Servers
NOTE:
If you want your LUN to be accessible by multiple hosts, use locking or multipath access
control.
Ethernet-Host Connections
Before performing the connections between Ethernet and host, take note of the following
requirements:
•
Ethernet cables are user-supplied. We recommend you use CAT5e shielded STP type
network cables or cables with better performance types (important for meeting the
requirements imposed by emission standards).
•
Use of straight-through Ethernet cables with RJ-45 plugs.
•
Use of cross-over cables. These cables are automatically detected and rerouted for a
valid connection.
See the list below of connection types:
•
Directly to iSCSI initiators (software or hardware) or via the Gigabit Ethernet switches.
•
To servers equipped with iSCSI HBA, preferably a hardware TOE (TCP/IP Offload
Engine) card, then to client stations with an Ethernet NIC or iSCSI HBA.
•
The system presents its logical volumes via SCSI-like IDs and LUNs. These RAID
volumes then appear as iSCSI targets via the network.
