SNAplus2 High Availability Features
SNAplus2 High Availability Features
SNAplus2 already has high availability features built in, namely, LU
pools, and client/server configurations.
LU Pools for 3270, 3179G, and LUA
One of the most significant fault-tolerant feature s of SNAplus2 is the
LU Pool feature. This feature allows users of 3270, 3179G, and LUA to
access a pool of LUs rather than a specific LU. Configuration is simpler
because you do not need to know the exact LU name to use. Instead,
SNAplus2 allocates an available LU.
T he biggest benefit is that the LU pool is made up of LUs from separate
SNAplus2 LSs spanning multiple servers. This type of configuration
vastly reduces the number of single points of failure by mak ing the LUs
highly available. A diagram of the LU pool concept will help explain its
usefulness.
