HOME - Frequently Asked Questions
Ubuntu Server LTS Base image & latest update packages applied at time of shipping. The exact version of the OS is defined per release and published in the release notes. The current version of Ubuntu is 20.04. Other versions of Ubuntu or OS derivates are currently not supported or confirmed compatible with HOME.
Enterprise support for Ubuntu is available through https://ubuntu.com/support. It is also possible to check the free Ubuntu community for help (https://ubuntu.com/support/community-support)
For a list of services and applications running on a HOME server, please refer to this list.
Default ports in use are listed here. Some can be customized at installation time if required
HOME servers supplied by Lawo are coming with 36 (12+24) months of ProSupport. This is valid worldwide and is realized through local Dell partners. You can check your servers service status via the DELL Support website. For details, please refer to this page.
In principle, no general restrictions apply for antivirus tools running on HOME machines. However, some specific considerations are recommended before applying antivirus measures:
- Ubuntu is Debian based, so if the antivirus tool provides support for Debian it should generally mean it will work with Ubuntu.
- Antivirus tools can be very resource hungry, depending on their settings. Make sure, that resource intense processes, such as schedules for global virus scans, do not collide with high availability requirements of HOME, such as top-of-the-hour processes.
We understand that numerous 3rd party tools are in use to measure IT system behavior under stress and to check these systems for vulnerabilities. It is impossible for Lawo to monitor all these tools and maintain a compatibility list for HOME.
Instead, we recommend the careful use of such tools, taking into account the individual operating times and requirements for the availability of HOME. In principle, it is possible to install and operate tools in parallel with HOME, but it is important to ensure that HOME runs smoothly. Operate concurrent tools during idle times of HOME, and make sure they run idle when HOME is active. The responsibility for system setup and the transparency of pointing out competing applications in the event of an error lies with the system operator.
The specified DELL servers provide a dual SFP cage module plus 4 onboard RJ45 network connectors. Lawo does not provide SFPs for the fibre cages, but they can be sourced through the DELL website. The SFP module is based on a broadcom chipset to provide maximum compatibility.
Home is designed as an application existing of many microservicesto run on various host platforms, including physical server clusters or data center host platforms. Technically, a HOME instance could also be packed into a virtual machine. However, this option is not recommended until further notice.
Until further notification, these current confirmed hosting setups are binding:
- non-redundant instances of HOME (single leg) on mc² gateservers
- redundant instances of HOME (3-leg) on dedicated DELL R3x0 server cluster.
It is possible to have HOME running on DELL servers sourced through the customer, if they comply with this specification.
Lawo does not provide any specific server hardening at present. During installation, generic user credentials are configured. These can be changed at any time by the customer. After installation of a HOME system, network settings are configured to block outgoing or incoming internet connections.
