Omnissa Access System and Network Configuration Requirements

Consider your entire deployment, including how you integrate resources, when you make decisions about hardware, resources, and network requirements.

Supported vSphere and ESX Versions

The following versions of vSphere and ESXi servers are supported:

  • 8.0, 7.0, 6.7, 6.5

Compatibility Between Omnissa Access Service and Connector

With the Omnissa Access on premises service, you can use supported connector versions that are either the same or earlier than the service version. For example, with the Omnissa Access 23.09 service, you can use the connector version 23.09 and earlier. You cannot use a connector version that is higher than the service version. For example, you cannot use the 23.09 connector with the 22.09 service. Using the latest compatible version of the connector is recommended.

For information on supported versions, see Omnissa Customer Connect.

Note: Omnissa Access connector 22.05 is not compatible with the on-premises Omnissa Access virtual appliance.

Hardware Sizing Requirements

Ensure that you meet the requirements for the number of Omnissa Access virtual appliances and the resources allocated to each appliance.

Note: For new deployments, the default Omnissa Access sizing requirements are as follows:

  • 4vCPU
  • 8 GB Memory
  • 100 GB disk space
Number of UsersUp to 1,0001,000-10,00010,000-25,00025,000-50,00050,000-100,000

RAM (per server)8 GB8 GB8 GB16 GB32 GB
Disk space (per server)100 GB100 GB100 GB100 GB100 GB

Also, Ensure that you meet the requirements for the number of Omnissa Access connector instances. See Installing and Configuring Omnissa Access Connector.

Database Requirements

Set up Omnissa Access with the appropriate external database to store and organize server data.

The supported external databases are Microsoft SQL Server 2014, 2016, 2017, 2019, and 2022. For information about the Microsoft SQL database versions and service pack configurations supported, see the Omnissa Lifecycle Matrix.

The following database requirements apply. The exact specifications needed depend on the size and needs of your deployment.

Number of UsersUp to 1,0001,000-10,00010,000-25,00025,000-50,00050,000-100,000

RAM4 GB4 GB8 GB16 GB32 GB
Disk space50 GB50 GB50 GB100 GB100 GB

The SQL Server AlwaysOn capability is a combination of failover clustering and database mirroring, combined with log shipping for faster availability. AlwaysOn allows for multiple read copies of your database and a single read-write copy for operations. If your deployment environment has the bandwidth to support the traffic generated, the Omnissa Access database supports AlwaysOn.

Network Configuration Requirements

ComponentMinimum Requirement
DNS record and IP addressIP address and DNS record.
Firewall portEnsure that the inbound firewall port 443 is open for users outside the network to the Omnissa Access instance or the load balancer.
Reverse ProxyDeploy a reverse proxy such as F5 Access Policy Manager in the DMZ to allow users to access the Omnissa Access user portal remotely and securely.

Unified Access Gateway 2.8 and later supports reverse proxy functionality to allow users to access the Omnissa Access unified catalog remotely and securely. Unified Access Gateway can be deployed in the DMZ behind the load balancers that is front-ending the Omnissa Access appliance.

Port Requirements

Ports used in the server configuration are described in the following table.

Your deployment might include only a subset of the listed ports. For example:

  • To sync users and groups from Active Directory, Omnissa Access must connect to Active Directory.
  • To sync with ThinApp, Omnissa Access must join the Active Directory domain and connect to the ThinApp Repository share.

Note: For Kerberos authentication port requirements see the Installing Omnissa Access Connector 23.09 guide, Network Requirement section.

Time Synchronization

Configuring time synchronization on all Omnissa Access service and connector instances is required for a Omnissa Access deployment to function correctly.

For information on configuring time synchronization for the Omnissa Access service, see Configuring Time Synchronization for the Omnissa Access Service.

For information on configuring time synchronization for the Omnissa Access connector, see Installing and Configuring Omnissa Access Connector.

Supported Directories

You integrate your enterprise directory with Omnissa Access and sync users and groups from your enterprise directory to the service.

  • The Active Directory environment can consist of a single Active Directory domain, multiple domains in a single Active Directory forest, or multiple domains across multiple Active Directory forests.

    The Omnissa Access service supports Active Directory on Windows 2022, 2019, 2016, 2012 R2 with a Domain functional level and Forest functional level of Windows 2003 and later. A higher functional level might be required for some features. For example, to allow users to change Active Directory passwords from Workspace ONE, the Domain functional level must be Windows 2008 or later.

Supported Web Browsers to Access the Omnissa Access Console

The Omnissa Access console is a web-based application you use to manage the Omnissa Access service. You can access the Omnissa Access console from the latest versions of Mozilla Firefox, Google Chrome, Safari, and Microsoft Edge.

Supported Browsers to Access the Workspace ONE Intelligent Hub Portal

End users can access the Hub portal from the following browsers.

  • Mozilla Firefox (latest)
  • Google Chrome (latest)
  • Safari (latest)
  • Microsoft Edge browser
  • Native browser and Google Chrome on Android devices
  • Safari on iOS devices
