I don't have net-snmp running anywhere convenient to check how it looks at
the moment, but to get a value in bytes, hrStorageSize needs to be multiplied
by the associated entry from hrStorageAllocationUnits.

Sensors works very nicely over snmp, but you are missing that by
default snmpwalk doesn't walk over vendor mibs.
"If no OID argument is present, snmpwalk will search the subtree rooted
at SNMPv2-SMI::mib-2 (including any MIB object values from other MIB
modules, that are defined as lying within this subtree)"
