The following guidelines provide a range of choices for the type of system you wish to deploy. These guidelines focus on small, stand-alone systems with options for managed applications. This focus on a quick start deployment still gives you considerable flexibility, starting with these guidelines for preferred hardware types, followed by recommendations for each hardware type.

Preferred hardware by component

The following tables show preferred hardware types for different InTouch functions. For comparison purposes, standalone applications are included along with managed applications.

Also included for reference is InTouch Access Anywhere (ITAA), an InTouch extension that provides mobile and casual users access to InTouch applications via HTML5-compliant web browsers. ITAA appears grouped with RDP (Remote Desktop Protocol) which provides a graphical interface to connect to another computer over a network connection.

Hardware recommendations

The following table shows both minimum and recommended hardware-specific levels of storage, RAM, and network speed for each hardware type, sorted by application type. Recommendations are limited to small systems, either all-in-one or standalone client and standalone server systems. Hardware requirements for larger, distributed systems are provided later in the InTouch HMI deployment guide, larger system deployments.

This table also includes hardware more specific to the Application Server IDE, necessary for managed applications, for comparison purposes.

Hardware class	Application	Level	Processors Cores	RAM	Free Disk Space	Network Speed
Thin Client Node Hardware	Thin Client Nodes
	RDP clients, ITAA, mobile devices	Minimum	2	512 MB	Not applicable	100 Mbps
	RDP clients, ITAA, mobile devices	Recommended	4	2 GB	Not applicable	100 Mbps
Client Node Hardware	Client Nodes
	WindowViewer, ViewApp (IDE), Historian Client, Remote IDE	Minimum	4	1 GB	100 GB	100 Mbps
	WindowViewer, ViewApp (IDE), Historian Client, Remote IDE	Recommended	8	4 GB	200 GB	1 Gbps
Server Node Hardware	Application Server Nodes
	Small Application (1 - 25K I/O per Node)	Minimum	4	2 GB	100 GB	100 Mbps
	Small Application (1 - 25K I/O per Node)	Recommended	8	4 GB	200 GB	1 Gbps
Thin Client Server Node Hardware	Remote Desktop Server Nodes
	Basic RDS, ITAA Server (Supports up to 15 concurrent remote sessions)	Minimum	8	8 GB	200 GB	1 Gbps
		Recommended	16	12 GB	500 GB	1 Gbps
All-In-One Demo Node Hardware	All-In-One Nodes
	Small Application - All products on one node: 1,000 I/O max.	Minimum	8	8	200 GB	100 Mbps
		Recommended	12	12 GB	500 GB	1 Gbps
Notes	Processors cores: Indicates physical cores. Note that the number of Logical Cores available to applications running on the CPU may be higher due to hyperthreading, but this table refers to the number of physical cores in the CPU die. Free disk space: SSD drives are highly recommended. In redundant environments, increase CPU and RAM to maintain a maximum of 40% typical resource utilization (60% free resources). For optimal performance of all-in-one nodes, a high clock speed (greater than 3.0 GHz) is recommended. For Application Server platform nodes, it is recommended that you deploy no more than two AppEngines per logical processor (typically one primary AppEngine and one backup). For large applications on all-in-one nodes, dual XEON processors are recommended.
