Pre-requisites for Installation

MongoDB runs on most OSes, Linux, Mac, Windows, Solaris, etc, but only on little-endian hardware. Also, 64-bit hardware is usually needed. The 32-bit version of MongoDB can only hold 2GB of data.

MongoDB automatically uses all free memory on the machine as its cache hence, RAM is the most important resource and the server should have enough RAM to hold the working set and enough CPU power to accomplish processing as well as network capacity to respond to queries.
