Eh?
This rather relies on the hrStorageTable *only* reporting memory usage.
That is a somewhat dangerous (read broken/wrong) assumption.
This particular table is designed for reporting a range of storage types,
including fixed, network and removeable disks, as well as memory,
buffers, and assorted other types of storage.
It would seem more sensible to take the value for physical memory from
the MIB object HOST-RESOURCES-MIB::hrMemorySize
which is defined as being
"The amount of physical read-write main memory,
typically RAM, contained by the host."
