## Introduction
OCP Delta Lake server platform is a component of multi-host server system
Yosemite-V3. Both were announced by Facebook and Intel in [OCP virtual summit 2020].
Yosemite-V3. Both [Delta Lake server design spec] and [Yosemite-V3 design
spec] were contributed to [OCP].
Delta Lake server is a single socket Cooper Lake Scalable Processor (CPX-SP) server.
Intel Cooper Lake Scalable Processor was launched in Q2 2020.
Yosemite-V3 has multiple configurations. Depending on configurations, it may
host up to 4 Delta Lake servers (blades) in one sled.

The Yosemite-V3 system is in mass production. Facebook, Intel and partners
jointly develop Open System Firmware (OSF) solution on Delta Lake as an alternative
solution. The OSF solution is based on FSP/coreboot/LinuxBoot stack. The
OSF solution reached DVT exit equivalent status.
OSF solution reached production quality for some use cases in July, 2021.
## Required blobs
## How to build
Delta Lake server OSF solution requires:
OSF code base is public at
https://github.com/opencomputeproject/OpenSystemFirmware
Run following commands to build Delta Lake OSF image from scratch:
git clone https://github.com/opencomputeproject/OpenSystemFirmware.git
cd OpenSystemFirmware/Wiwynn/deltalake && ./download_and_build.sh
The Delta Lake OSF code base leverages [osf-builder] to sync down coreboot,
Linux kernel and u-root code from their upstream repo, and sync down needed
binary blobs. [osf-builder] also provides the top level build system.
Delta Lake server OSF solution requires following binary blobs:
- FSP blob: The blob (Intel Cooper Lake Scalable Processor Firmware Support Package)
is not yet available to the public. It will be made public soon by Intel
with redistributable license.
can be downloaded from https://github.com/intel/FSP/tree/master/CedarIslandFspBinPkg.
- Microcode: Available through github.com/intel/Intel-Linux-Processor-Microcode-Data-Files.
coreboot.org mirrors this repo and by default the correct binary is included.
- ME binary: Ignition binary will be made public soon by Intel with
redistributable license.
- ME binary: Ignition binary can be downloaded from
https://github.com/tianocore/edk2-non-osi/tree/master/Silicon/Intel/PurleySiliconBinPkg/MeFirmware
- ACM binaries: only required for CBnT enablement. Available under NDA with Intel.
## Payload
- LinuxBoot: This is necessary only if you use LinuxBoot as coreboot payload.

U-root as initramfs, is used in the joint development. It can be built
