此性能监控工具会游走 (Walk) hrStorageType MIB，以寻找保存表中的硬盘。找到硬盘后，监控工具会取得硬盘索引，并轮询新的对象 (保存空间大小与单位)。
// This scripts walks hrStorageType to find hard disks in the storage table.
// A hard disk as a hrStorageType of "1.3.6.1.2.1.25.2.1.4" (hrStorageFixedDisk).
// Then it gets the indexes of the hard disk in that table and for each index, it polls two new
// objects in that table, the storage size and the units of that entry.
// It adds everything up and converts it in Gigabytes.
