ON PREMISES SOLUTIONS

HVI

HVI operates with the help of two components: Security Server and HVI Supplemental Pack. These products need to be installed on the hosts in your virtualized environment where you have virtual machines you want to protect.

Note

The HVI service may be available for your GravityZone solution with a separate license key.

Before you deploy HVI on hosts, make sure that the following requirements are met:

Supported virtualization platforms

  • Citrix XenServer 7.1 LTSR Enterprise Edition, with latest patches

  • Citrix Hypervisor 8.2 LTSR Enterprise Edition or higher, with latest patches

Important

For any XenServer/Hypervisor that reached EOL, Bitdefender provides HVI support for two additional months. After this period, we recommend updating to a version supported by Citrix.

Supported guest virtual machines

The virtual machines you want to protect with HVI must meet the following conditions:

  1. The machines are in HVM Virtualization Mode, meaning that they are fully virtualized.

  2. The machines run a supported operating system:

    • Windows desktop operating systems (32-bit and 64-bit)

      • Windows 11 (initial release)

      • Windows 10 November 2021 Update (21H2)

      • Windows 10 October 2020 Update (20H2)

      • Windows 10 May 2020 Update (20H1)

      • Windows 10 November 2019 Update (19H2)

      • Windows 10 May 2019 Update (19H1)

      • Windows 10 October 2018 Update (Redstone 5)

      • Windows 10 April 2018 Update (Redstone 4)

      • Windows 8.1

    • Windows Server operating systems (64-bit)

      • Windows Server 2019

      • Windows Server 2016

      • Windows Server 2012 / Windows Server 2012 R2

    • Linux operating systems (64-bit)

Important

It is highly recommended to use Solid-state drives (SSDs).

* Additional SSD space required when choosing the automatic installation, because it also installs the Security Server. After installation is complete, you can uninstall the Security Server to free disk space.

** In case of distributed installation of roles, along with Replica Set: for each additional Database instance, add the specified number to the total amount.

Hardware requirements for hosts

  • CPU microarchitecture:

    • Any Intel® Sandy Bridge processor or later, with support for Intel® Virtualization Technology.

    • VT-x or VT-d extensions must be enabled in BIOS.

  • Free HDD space: Besides the space required by the Security Server, HVI requires another 9 MB for the Supplemental Pack on each host.

Security Server requirements

Memory and CPU resource allocation for the Security Server depends on the number and type of VMs running on the host. The following table lists the recommended resources to be allocated:

Free HDD space: You must provision 8 GB disk space on each host for the Security Server.

For an optimal performance in a XenAPP environment, scale the Security Server's resources based on your configuration, as follows:

Guest virtual machines requirements

In a usual environment setup, for optimal performance and VM consolidation ratio, it is recommended to have the following minimum hardware configuration for the guest virtual machines:

  • vCPU: 2 x vCPU

  • RAM: 3 GB
