    mechanisms to automate interactions with hardware •  PXE •  IPMI Existing software focused solely on provisioning HARDWARE MANAGEMENT Razor/Hanlon xCat DHCP TFTP HTTP …some software…

    Software “tap roots”: some software very specific to firmware versions •  Upgrading some firmware requires rebooting in the process •  Want to be API driven, not another mandatory human touch-point PROBLEMS TO OVERCOME DHCP TFTP HTTP …some software… REST API Want to extend with vendor specific tooling Different tasks or goals mean different logic – embedding “know how”

    Asynchronous; many things happening at once •  Possible to common remote failure or intermittent failure •  Multiple network protocols COMMON DISTRIBUTED SYSTEM PROBLEMS

    Some background with javascript, none with Go •  Proved to ourselves we could get stuff done fast •  Prototypes worked fast and well But… WHY

    We didn’t really grok how asynchronous JS was •  Inadvertent bloat –  Memory –  CPU •  Finding solid libraries •  Building and packaging •  “Dynamic ecosystem” and tooling change NOT WITHOUT CHALLENGES

    Hardware Management and Orchestration •  Open Sourced by EMC Dec 2015 •  Screencast Overview –  https://www.youtube.com/watch?v=cCiXtROSt8U HTTPS://GITHUB.COM/RACKHD/RACKHD HTTP://RACKHD.READTHEDOCS.ORG/

    Vendor Agnostic •  Discovery, Cataloging, Telemetry •  Component in Larger Stack •  Hardware Configuration capabilities •  Automation of the lowest layer most stacks –  Provisioning –  Configuration –  Metrics and Events VISION

    Stepping beyond existing provisioning systems –  Declarative Workflow engine –  Working closely with PXE capabilities –  Built to be a component in a larger stack up •  REST API •  Telemetry/Data Feeds •  It’s not a scheduler or reactive system •  Minimal “knowledge” layers above hardware WHAT IT IS AND ISN’T

    iPXE oriented bootloader •  SKU identification based on rules •  PXE based compute server discovery process •  Free-format data catalogs •  Integral monitoring/telemetry with Out of band management •  Multiple Out-of-band management capabilities (via plugin) •  Remote discovery and telemetry support for PDU and switches •  Compute server telemetry available via IPMI and SNMP •  Live structured data feeds with Websockets or AMQP •  Declarative Workflows •  Composed of tasks – in serial or parallel – acyclic graphs •  Custom images easily included and used in workflows •  Leverage templates and profiles (dynamic file & ipxe scripts based on workflow data) CURRENT CAPABILITIES

    SKU packs –  Load templates, profiles, microkernels, and sku definitions for specific hardware or OS personalities •  V2 API –  More solid schema definition, swagger based •  Fault tolerant workflow processing •  Hardware connection topology •  Additional south-bound discovery protocols –  Adding Redfish 1.0 support to IPMI and SNMP •  Additional workflow capabilities –  Secure Erase –  In-band management tasks –  Enhanced workflow programmability UPCOMING CAPABILITIES
