Reference Architecture VM Specifications
This chapter is one of a series that make up the Omnissa Workspace ONE and Horizon Reference Architecture, a framework that provides guidance on the architecture, design considerations, and deployment of Omnissa Workspace ONE and Omnissa Horizon solutions. This chapter provides information about the specifications for the various management servers and connector virtual machines used to validate the reference architecture.
Workspace ONE UEM
Several servers are required to take advantage of all features in an Omnissa Workspace ONE UEM deployment.
AirWatch Cloud Connector server
Depending on the scale of the environment and the number of devices to be supported, the recommended resources allocated to each Omnissa AirWatch Cloud Connector VM can differ.
The AirWatch Cloud Connector synchronizes Workspace ONE with internal resources such as Active Directory or a Certificate Authority.

| Virtual disk – VMDK (scsi0:x) | Scsi0:1 Windows OS 100 GB |
Omnissa Access (formerly Workspace ONE Access)
Depending on the scale of the environment and the number of devices to be supported, the recommend resources allocated to each an Omnissa Access and Workspace ONE Access Connector VMs can differ. For this reference architecture, a 50,000-device deployment was considered. See Workspace ONE Access Architecture for guidance on sizing for different numbers of devices.
Omnissa Access Connector server
The Omnissa Access Connector is responsible for directory synchronization and authentication between on-premises resources such as Active Directory, Horizon, and the Access service.
The Access Connector can be used in both cloud-based and on-premises deployments of Omnissa Access.

Omnissa Access appliance
This server hosts the Access service, which provides the app catalog, conditional access, and single sign-on. Access appliances are required only in an on-premises deployment of Access.

Workspace ONE Intelligence
Omnissa Workspace ONE Intelligence is designed to simplify user experience without compromising security. The intelligence service aggregates and correlates data from multiple sources to give complete visibility into the entire environment. Workspace ONE Intelligence requires its own connector server.
Intelligence Collection Service - ETL Connector Server
This server hosts the ETL (Extract, Transform, Load) service responsible for collecting data from the Workspace ONE database and feeding it to the Workspace ONE Intelligence cloud service. The ETL Connector Server is only required when connecting an on-premises deployment of Workspace ONE UEM with Intelligence.

Workspace ONE Assist
Omnissa Workspace ONE Assist allows Workspace ONE UEM administrators to remotely access and troubleshoot devices in real time while respecting end-user privacy. Screen-sharing capabilities allow remote devices to screen share and relinquish device controls to an administrator for guided support. Administrators can also access the remote file system and can use run commands to remotely send commands to the device.
Workspace ONE Assist all-in one server
This server hosts the Core, Application, Portal, and Connection Proctor components on a single server. All Workspace ONE Assist Core Service servers, Connection Proctor servers, and remote management registration details persist and reside in a Microsoft SQL Server database.
Note: You may use the same Microsoft SQL Server that supports your Workspace ONE UEM deployment for your Workspace ONE Assist deployment. For VM specifications, see SQL Server for Workspace ONE UEM.

Horizon 8
Several servers are required to take advantage of all features in an Omnissa Horizon 8 deployment.
Horizon Connection server
This server acts as a broker for client connections. It authenticates users through Windows Active Directory and directs the request to the appropriate virtual machine, physical PC, or Microsoft RDSH server.
