Fix VMWare ESXi 6.* slow disk performance on HP b120i controller

Even though this post is fairly dated, I will leave this post online just in case anyone still has an HP ProLiant ML310e or MicroServer Gen8 server with terrible disk performance.

How to repair a corrupted/broken Fibaro HC2 Recovery USB Key

This guide is no longer necessary since software update 4.5xx because they made the USB recovery key unnecessary. I guess they had too many problems with it. Disclaimer This guide worked for 2 people that had the problem where the Fibaro HC2 would not boot with the recovery stick connected,...

Install vSphere client 5.0, 5.1, 5.5 and 6.0 on Windows Server 2003

When I booted up the guest OS, the network connection was called "LAN connection 2" instead of just...

Pin-out of Fritz!Box Y-cable
