SmartServer IoT Specifications

Hardware Specifications

The hardware for the SmartServer IoT has the following specifications:




800 MHz Quad Core ARM Cortex A9

Quad core vs. dual core

Starting with Revision F of the SmartServer IoT, all SmartServers include a quad core ARM processor. Earlier SmartServer IoTs included a dual core processor. To determine which processor you have, read the label on the bottom of the SmartServer. The serial number printed just under the product name includes one letter. If the letter is F or later, you have a quad core processor. If the letter is A through E, you have a dual core processor. For more information, see the SmartServer Release Notes for SmartServer IoT 2.9.
