This talk is about the bmc-toolbox, an open-source project that leverages the _Baseboard Management Controller_ (iLOs iDracs and similar) to help manage a large fleet (&gt50K) of bare metal servers at Booking.com Its goal is to provide vendor agnostic tooling to manage the lifecycle of bare metal servers, this talk describes the tools part of bmc-toolbox and various aspects of managing a large fleet of bare metal servers. The bmc-toolbox leverages the _Baseboard Management Controller_ to help manage the lifecycle of datacenter bare metal. It provides vendor agnostic tools and a library in Go lang to *inventorize*, *configure*, *manage**, **update* a large fleet of bare metal assets with the help of the BMC. - *bmclib* - A Go lang library that provides a consistent set of methods to interface with BMCs. - *dora* - tool to **inventorize** a fleet of bare metal servers and chassis assets. - *bmcbutler* - tool to handle **configuration management** for a fleet of bare metal server and chassis BMCs. - *actor* - A single **API webservice** endpoint to interact with a fleet of bare metal BMCs. - *bmcldap* - LDAP based **authentication/authorization** service/proxy for BMCs. - *bmcfwupd* - tool to **update** the BMC firmware. This talk covers, - The challenges managing the provisioning and lifecycle of a *not yet hyperscale* size set of bare metal servers. - The purpose of the tools included of bmc-toolbox, how they help make our lives easier - How the tooling interacts with the BMCs (vendor specific APIs, Redfish) - The current state of Redfish in the wild
