whAt is A nAs POrtAl?
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:
