По логике, можно вынимать выключенные ноды из шасси, не выключая остальные ноды. В описании продукта не нашел такой информации. На шасси и в документации — только в выключенном состоянии. А в статьях про модели H261-Z6Х толстый намёк на возможность горячего отключения.
На шасси предупреждение:Disconnect all AC power cords from both system and external peripherals prior to installing/removing options.
В User Guide:System power on/off: To service components within the server, please ensure the power has been disconnected.
e.g. Remove the node from the server chassis (to disconnect power) or disconnect the power from the server chassis.
Make sure the system is removed from the rack before opening the chassis, adding, or removing any non hot-plug components.
Из статьи про H261-Z61 https://www.servethehome.com/gigabyte-h261-z61-server-review-2u4n-amd-epyc-with-nvme/Since this is a 2U 4-node design, there are four long nodes that each pull-out and can be hot swapped from the rear of the chassis. This makes servicing extremely easy. If you have a rack of these servers, one can replace a node into another chassis without having to deal with rack rails. From a servicing perspective, the 2U4N works very well
Из статьи про H261-Z60 https://www.techpowerup.com/forums/threads/gigabyte-expands-amd-epyc-family-with-new-density-optimized-server.245552/GIGABYTE continues our active development of new AMD EPYC platforms with the release of the 2U 4 Node H261-Z60, the first AMD EPYC variant of our Density Optimized Server Series. The H261-Z60 combines 4 individual hot pluggable sliding node trays into a 2U server box. The node trays slide in and out easily from the rear of the unit.
Ответ техподдержки GigabyteДля отключения нодов необходимо отключать питание сервера. С включенным питание отключение не поддерживается.
