Storage area network (SAN) switches having greater storage capacity to allow greater data logging and storage of larger, more complicated tables for zoning and other table-based applications. A hard disk drive can be included in the switch, with data logging performed to the hard disk drive and with the hard disk drive serving as a second level of virtualization to provide storage of large tables. In a variation, the data logging of the switch, and any other devices on the SAN, can be directed to an area or areas of one or more storage units attached to the SAN.
