Figure 2-4 Position of the HDLM Driver and hdisk

Distributing a Load Using Load Balancing

When the system contains multiple paths to a single LU, HDLM can distribute

the load across the paths by using multiple paths to transfer the I/O data.

This function is called load balancing, and it prevents a single, heavily loaded

path from affecting the performance of the entire system.

Figure 2-5 Flow of I/O Data When the Load Balancing Function Is Not Used on

page 2-9 shows the flow of I/O data when the load balancing function is

not used. Figure 2-6 Flow of I/O Data When the Load Balancing Function Is

Used on page 2-10 shows the flow of I/O data when the load balancing

function is used. Both figures show examples of I/O operations being issued

for the same LU by multiple applications.
