I've been working on a rpi 4 version of this. The pi4 supports gadget mode and host mode simultaneously so I have a HDMI framegrabber (and VGA->HDMI for the machines that don't support HDMI) along with a 4 way HDMI kvm switch to allow me to control four machines from a single RPI (for circa 100GBP). There are other solutions on the web but all of them use the standard USB keyboard gadget that doesn't work with every bios that I have so I've had to build my own. Let me know if you're interested but it's not quite "production ready" yet - the electronics to control the power and reset switches and monitor the power and HDD led are on a breadboard at the moment...

I did like the Xeon-D at that time. I wanted to position them as servers for bioinformatics (gene sequencing). I never quite achieved that and do regret it.

It might be worth comparing rack rental costs vs using a VM on a service provider. The Surrey LUG server that I help maintain is a VM. Fortunately the VM is donated to us by the service provider, so it costs us nothing. But saying that, the resources it takes up are minimal so the service provider hardly notices it. I think it averages about 1 page hit per day! If you are a charity, it might be worth asking some service providers if they would donate a VM for your use also. I think the IBM X3250s have an option remote management card, that would do the same job as iDRAC, LOM. I don't know about the SUN ultras.

Re: [GLLUG] Power control over IP
Marco, you have summarised things very well here. As an addition, you do not have to look at the rear of the server to figure out if the server has IPMI. Install the ipmitool package on your server (whatever the package name is) Start the ipmi system service The modules loaded should be ipmi_msghandler ipmi_si ipmi_devintf Then run 'ipmitool bmc info' and see if there is indeed a BMC installed As you say though - you do need either to connect a physical cable to the dedicated BMC port or configure piggyback (bridged) mode to use the motherboard ethernet socket. Sorry if any of the above information is slightly off - I Am remembering these rather than testing on a live server.

I'm not quite clear whether you are looking for an IP controlled PDU or per server remote KVM. There's various PDUs available, as in other replies, with per socket control. Per rack most UPS with IP can do this. Per server if no built in iLO then Lantronic Spider is traditional, new offerings coming along Raspberry Pi based but I'd only use those on my home gear. I'm not fond of APC for UPS as their income stream IMO depends on short battery life, but their PDUs seem fine.

Re: [GLLUG] Power control over IP
I am a principal engineer with Dell. As James says, Dell servers have iDRAC controllers which permit full remote operations on servers. We can read out power consumption, fans speeds (etc. etc.), do firmware upgrades to fleets of servers using Openmanage enterprise and proactively monitor for failures (*) If anyone needs help with iDRACs I am happy to provide some advice. If it is a deeper technical issue I can contact engineering with your question. There are remote KVM solutions - these were popular in the past in HPC but I haven't seen one in use for years. Raritan brand rings a bell. Regarding IP controllable power sockets APC/Schneider as said are a popular brand. Note of course that you have to have an ethernet cable going to that APC Power Distribution Unit! Note also you want the BIOS set to Resume when Power is applied. no use in switching a server off if.. Errr... you cant turn it on. Regarding the network connection, iDRAC (and other BMC such as Supermicro) can use a dedicated physicsl socket or can share the motherbord ethernet socket. Most HPC setups have a dedicated iDRAC/BMC setup with PDU connections on separate 1Gbps switches. I would say that it is good practice to have a dedicated and separate network for what I as a physicist would call 'slow control'. (*) there are different license levels for idRAC. You need the Enterprise license for some of those features.

Dell ones have iDRAC and HP ones have LOM (Lights out management) It allows access to power on/off the OS like you were pressing the power button, and also access to the console like VNC, but it allows you to see BIOS boot up messages also. So, what I am trying to say, is your server might already have the features you are asking for. You can also add PDUs and UPSs that are controllable over TCP/IP if you need them.
