Access "Directors take on more tasks"
This article is part of the Vol. 4 No. 4 June 2005 issue of Exploring new options for disk-based backup
The competition among director-class products has never been more intense. If you're considering directors for the first time, or re-examining your fabric strategy, here's what you need to know. (This article orginally appeared in the June 2005 edition of "Storage" magazine.) In the early days of storage networking, Fibre Channel (FC) switches with four to 32 ports served the needs of most organizations. When requirements scaled beyond 32 ports, switches were connected using inter-switch links (ISLs). This architecture gradually evolved into a so-called "core-to-edge" fabric, with larger switches in the "core" and smaller switches at the "edge" of the storage infrastructure. Data directors were reserved for "monolithic" implementations, usually focused on the mainframe. Indeed, it's the mainframe environment from which data directors (also called channel directors) evolved. In the open-systems world, these products are called director-class switches, but the architecture is the same: More than 128 ports in a single package (frame) designed to offer high, ... Access >>>

iFCP vs. FCIP
Two protocols—iFCP and FCIP—tap the scalability of the Internet Protocol and Ethernet networks, and can be used to overcome Fibre Channel networking limitations when connecting SAN islands. But iFCP and FCIP operate very differently; find out which one is right for your environment.
