Introduction
Figure 1-3. Non-Redundant iSCSI Path With Three NICs
NOTE:
For 3.0 iSCSI Target—In Figure 1-4 and Figure 1-5, both Initiators can
communicate to the Active PowerVault NX1950 storage node through the dedicated
iSCSI link (indicated by blue links from Initiators to switch and Active PowerVault
NX1950 storage node). The active node owns the cluster group. The passive node
and link are active only when the active link from the switch to the active node is
lost or the active node dies.
NOTE:
For 3.1 iSCSI target—In Figure 1-4 and Figure 1-5 with Active/Active target,
both Initiators can communicate to both PowerVault NX1950 storage nodes through
the dedicated iSCSI link (indicated by blue links from Initiators to switch and
PowerVault NX1950 storage nodes). If one node fails, the surviving node takes
ownership of all iSCSI Targets of the failed node and continues the I/O operations.
