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.
