Figure 1-12. GFS with a SAN
1.5.2. Performance, Scalability, Moderate Price
Multiple Linux client applications on a LAN can share the same SAN-based data as shown
in Figure 1-13. SAN block storage is presented to network clients as block storage devices
by GNBD servers. From the perspective of a client application, storage is accessed as if
it were directly attached to the server in which the application is running. Stored data is
actually on the SAN. Storage devices and data can be equally shared by network client
applications. File locking and sharing functions are handled by GFS for each network
client.
