Although you can create individual LUs and assign them to users and groups, using LU pools to manage and deploy a large number of LUs is a more efficient method of administering these resources. LU pools are groupings of LUs that allow you to maximize access to these LUs, as shown in Figure 10.9. A user, an application, or a downstream system can access the LUs as long as any LU assigned to the pool is free. If any one of the pooled LUs ceases to function, another free LU in the pool is used.
Figure 10.9 Creating and Assigning LU Pools
LU pools also allow groups of intermittent users to use a limited number of host resources more efficiently. Dedicating LUs to specific users who occasionally require host access wastes host resources. Using a pool, you can assign a smaller number of LUs to a group of users who require sporadic access. For example, if a group of 100 users requires host access 25 percent of the time, assigning a pool of 25 LUs to the group might fulfill their needs.
