In systems management, out-of-band management involves the use of management interfaces (or serial ports) for managing and networking equipment. Out-of-band management allows the network operator to establish trust boundaries in accessing the management function to apply it to network resources. It also can be used to ensure management connectivity (including the ability to determine the status of any network component) independent of the status of other in-band network components.

Property Value
dbo:abstract
  • Lights Out Management (LOM) erlaubt einem Systemadministrator, auf ein Serversystem zuzugreifen, unabhängig davon, ob es eingeschaltet ist, oder, ob ein Betriebssystem installiert wurde. Der Name „Lights Out“, dt. „Lichter aus“ rührt daher, dass im Rechenzentrum das Licht nicht mehr brennen muss, weil sich niemand darin aufhält. Die LOM-Funktionalität ist üblicherweise bei Rechnersystemen verfügbar, die im Serverbereich eingesetzt werden und vor allem für den Dauerbetrieb ausgelegt sind. Teilweise wird diese Technik aber auch bei zentral verwalteten Arbeitsplatzrechnern, beispielsweise zur softwareunabhängigen Fernwartung von der EDV-Abteilung aus, eingesetzt. (de)
  • In systems management, out-of-band management involves the use of management interfaces (or serial ports) for managing and networking equipment. Out-of-band management allows the network operator to establish trust boundaries in accessing the management function to apply it to network resources. It also can be used to ensure management connectivity (including the ability to determine the status of any network component) independent of the status of other in-band network components. In computing, one form of out-of-band management is sometimes called lights-out management (LOM) and involves the use of a dedicated management channel for device maintenance. It allows a system administrator to monitor and manage servers and other network-attached equipment by remote control regardless of whether the machine is powered on, or whether an operating system is installed or functional. By contrast, in-band management through VNC, SSH or even serial ports is based on in-band connectivity and software that must be installed on the remote system being managed and only works after the operating system has been booted. This solution may be cheaper, but it does not allow access to firmware (BIOS or UEFI) settings, does not make it possible to reinstall the operating system remotely, and it cannot be used to fix problems that prevent the system from booting. In networking, it does not allow management of remote network components independently of the current status of other network components. Both in-band and out-of-band (OOB) management are usually done through a network connection, but an out-of-band management card can use a physically separated network connector if preferred. A remote management card usually has at least a partially independent power supply and can switch the main machine on and off through the network. Modular/blade systems with dedicated management modules often offer dedicated OOB Ethernet port or Lights out management port. (en)
  • 在计算机领域,带外管理(Out-of-band management)是指使用独立管理通道进行设备维护。它允许系统管理员远程监控和管理服务器和其他网络设备,无论这些设备是否处于开机状态。 相对的,带内管理是指使用常规数据通道(例如以太网)来管理设备。带内管理的明显限制是这种管理容易受到被管理设备受攻击或损害的影响。要远程管理出现故障的网络服务器和路由器,IT管理员需要能通过网络访问它们。但如果网络发生故障,就无法远程管理那些设备。 带外管理通过部署与数据通道物理隔离的管理通道来解决这个限制。 (zh)
