A portal is the logical point of connection between the Vess R2000 Series and the NAS clients. Portals use an IP
address and a TCP port number to identify an IP storage resource. Normally only one portal is created for NAS,
though multiple portals can be used for NAS. Many portals might be used for iSCSI operations.
Vess R2000 Series supports both IPv4 and IPv6 addresses.
Portals on Vess R2000 Series supports the following types of port associations:
• Port ID – The number of the Gigabyte Ethernet data port associated with the portal.
• Controller ID - For dual controller subsystems, the Controller ID and Port ID indicate the physical data port
associated with the portal.
• VLAN – Virtual Local Area Network. The portal is part of a virtual network, data frames contain a VLAN tag
read by switches and routers to indicate what VLAN it belongs in.
• Trunk – An aggregation of two or more Gigabyte Ethernet ports on the same controller. Also known as a
link aggregation. This feature combines ports to increase bandwidth.
