MIB: HOST-RESOURCES-MIB
The size of the storage represented by this entry, in units of hrStorageAllocationUnits.
This object is writable to allow remote configuration of the size of the storage area in those cases where such an operation makes sense and is possible on the underlying system.
For example, the amount of main storage allocated to a buffer pool might be modified or the amount of disk space allocated to virtual storage might be modified.
