2、ions Configuring PBHA Common Deployment ModelsIntroducing the Storage Partition PurposeWe needed an object that could encapsulate not only an applications data but also all of the logical configuration required to make the data available to the sever.i.e.the volumes(in volume groups),the logical hos

4、IdeologyToday,a single system can contain at most 32 partitions*.Storage Partitions have two primary use cases:To provide High Availability using PBHA To migrate data between systems Why only 4 partitions initially?1.HA partition with preference to this system.2.HA partition with preference to the r
