The connection from the Proxmox VE host through the iSCSI SAN is referred to as a path. If you use iSCSI, multipath is recommended - this works without configuration on the switches (If you use NFS or CIFS, use bonding, e.g. Another advantage of multipathing is the increased throughput by way of load balancing.Ī common example for the use of multipathing is to add redunancy and gain maximum performance from an iSCSI SAN device. The main purpose of multipath connectivity is to provide redundant access to a storage device, i.e., to have access to the storage device when one or more of the components in a path fail. 3.2.1 Prioritizing a Certain TCP/IP Path. ![]()
