Hardware and software requirements for XClarity One virtual machine

XClarity One runs as a virtual appliance on a host system that is installed locally in your datacenter. The following requirements must be met.

Host requirements​

Host environment
The following hypervisors are supported for running XClarity One as a virtual appliance.
  • VMware ESXi 8.0 or later (.ova)
  • Microsoft Windows Server 2022 or 2025 with Hyper-V (.vhdx)
Hardware requirements

The following table lists the minimum recommended configurations for the XClarity One virtual appliance based on the number of managed devices. Depending on your environment and use of provisioning functions (such as firmware updates, device settings, and operating system deployment), additional resources might be needed for optimal performance.

  • 8 virtual processor cores

  • 16 GB memory

  • 768 GB storage, across two attached disks.

    • 256 GB minimum for the virtual appliance (disk 0)

    • 512 GB minimum for the repository (disk 1)

Software requirements
XClarity One requires the following software.

  • Lenovo XClarity One Hub

    XClarity One monitors and manages devices through one or more light-weight device managers, called hubs. Hubs are installed on premise in your data centers. They can be set up across multiple sites, where your devices are located.

    The management hubs communicate directly with the XClarity One portal and managed device. Managed devices communicate only with the hubs. They cannot communicate directly with XClarity One portal.

    Attention
    XClarity One as a local VM support a maximum of 1,000 devices that are managed by one or more hubs.

  • NTP server

    A Network Time Protocol (NTP) server is required to ensure that timestamps for all events and alerts that are received from managed devices are synchronized with XClarity One. Ensure that the NTP server is accessible over the management network (typically the Eth0 interface).

    Tip
    Consider using the host system on which XClarity One is installed as the NTP server. If you do, ensure that the host system is accessible over the management network.

  • Authentication server

    Lenovo XClarity One uses an internal identity-management system to authenticate local users. You can choose to set up federation using your company’s existing identity provider (IDP) to provide seamless access to the XClarity One portal using corporate credentials without the need for additional user-account creation or management, while maintaining strong identity and access management practices.

    You can configure XClarity One portal to use a federation IDP that supports OIDC/OAuth, SAML, and LDAP protocols. If your identity provider is not currently supported, open a service ticket using the Submit an eTicket webpage.

Manageable resources​

XClarity One can support an unlimited number of hubs that collectively manage a maximum of total devices.

  • Lenovo XClarity One Hub v1.4 and later

    XClarity One manages and monitors devices that are under management by XClarity One Hub Each XClarity One Hub instance can manage up to devices.

    You can find a complete list of supported devices and options (such as I/O, DIMM, and storage adapters), minimum required firmware levels, and limitations considerations from the XClarity One Hub Support for Servers webpage.

    For general information about hardware configurations and options for a specific device, see the Lenovo Server Proven webpage.
