So if a machine behaves odd/goes away and its OS doesn't respond you don't want management plane to be able to redeploy it/run hardware checks/... automatically

- jeffbee 5y agoIf you put it that way you make it too simple. The question is whether I want a second, smaller computer inside my larger computer that may at any time corrupt memory, monkey with network frames, turn off the power, assert PROCHOT, or do a million other bad things. It's not just a tool with benefits. It has both benefits and risks, and in my experience the risks are not worth those benefits.
- detaro 5y agobut we are talking in the context of a project which specifically aims to do these things without the baggage of other platforms. And these things are BMC functions.
- p_l 5y agoSo, you manage computers using crashcarts like in ugly old days of PC servers? I thought that had considerable issue with scaling...
- jeffbee 5y agoI guess you thought wrong. What do you think this hardware tech is doing in this video? https://youtu.be/XZmGGAbHqa0?t=224 https://youtu.be/XZmGGAbHqa0?t=224 Men with carts scale perfectly. One guy can manage 1000 machines. 2 guys can manage 2000. Perfect scaling.
- p_l 5y agoI see no crashcart there, only hw maintenance while crashcarts are where they belong, in the trash of history (yeah, google servers have BMCs) (For reference: a crash cart is a cart with monitor, keyboard, mouse, cabling for them, and possibly external drives to help you install base OS, used for when you have no remote management)
