Appendix A: Multipathing Support for High Availability
ES NAS support connections from multiple hosts with multiple-port configurations in an iSCSI storage
area networking (SAN) environment and utilizes standard Ethernet infrastructure. This
allows connectivity of a host computer running a Windows server-class operating system with
integrated Multipath I/O (MPIO) support.
Multipath solutions employ a redundant network infrastructure to create interconnecting paths
between the server, network and storage device. The alternative paths of the redundant network
infrastructure allows for continued access in the event that one or more of these network devices fail.
Each Storage Controller should be connected using such redundant network infrastructure to ensure
uninterrupted access to storage. The following diagram is an example of how the configuration
should be implemented.
Follow these guidelines when configuring iSCSI connections:
Do not configure any two Ethernet interfaces on the same subnet. Each Ethernet interface must
be on a separate subnet.
The QES only allows fixed IP address configuration for Ethernet ports designated for data
services.
Isolate iSCSI network traffic from other network traffic by using VLANs or separate network
equipment.
