QNAP ES2486dc - Multipath I;O Network Configuration

Multipath I/O Network Configuration
Multipath I/O (MPIO) is a fault-tolerance technique where more than one physical network path is created
between a server and a storage device such as a NAS. If any one network path goes down due to the failure
of a switch, cable, or network card, the server can route I/O through the remaining network paths with no
storage downtime. The ES2486dc supports MPIO on iSCSI connections using standard Ethernet
infrastructure.
The following diagram shows an example multipath I/O network configuration:
Important
• Each QES data port must use a static IP address.
• Each server and storage controller must be connected to at least two different physical
switches on different subnets.
• Use dedicated network switches or VLANs to separate iSCSI traffic from other network
traffic.
