Intel® Rack Scale Design is an open framework that defines the standards for composing logical servers from disaggregated pools of storage, network and compute resources. MegaRAC Rack Scale Design Solutions enable high efficiency for building, managing and improving cloud infrastructure in a software-defined data center. These solutions are fully compliant with Intel® Rack Scale Design and DMTF Redfish standards. Included are the fully integrated Pooled System Management Engine (PSME) firmware solutions and the MegaRAC® Composer™ Pod Management Software.
MegaRAC PSME firmware solutions are hardened, production worthy and tightly integrated to function with the MegaRAC manageability firmware stack used by nearly every ODM and within most hyper-scale data centers. These solutions can be deployed in a single image to the popular (BMC) service processors, but are also configurable to run stand-alone on x86 or other architectures, and with custom OEM manageability firmware stacks. MegaRAC PSME solutions can not only run on compute nodes integrated with the server BMC, but also on Chassis or Rack Management Modules or they can run as a Container under the Pod Manager. These solutions all work under a Redfish Framework, making it easy to add extensions, such as Fabric Management.
MegaRAC Solutions for RSD offer a number of advantages for OxM customers
OxMs can integrate RSD functionality within the BMC or other Management Controller firmware on participating RSD hardware. Now, OxMs can build RSD solutions with already existing BMC development skills and infrastructure. Integrating RSD functions on BMC firmware ensures a quick path to production, without significant changes to the manufacturing process.
The MegaRAC RSD solutions framework is designed to work across a variety of existing server hardware including compute nodes, storage nodes and switches. It is also completely configurable to meet the needs of OxMs - right out of the box. This gives OxMs the ability to create their own custom proprietary solutions through their IP, on hardware they control.
MegaRAC solutions are one hundred percent out-of-band, eliminating the need for running required RSD software components on dedicated server nodes. This out-of-band aproach has intrinsic benefits, by freeing up the server node for doing more compute jobs, since processing power is not needed for running RSD tasks, as well as eliminating a potential single point of failure.
MegaRAC solutions are distributed BMC-based solutions on server nodes in a rack - as opposed to running on a dedicated node within a rack. This distributed approach eliminates a "single point of failure" threat when a crash on a dedicated node causes the entire rack to lose Rack Scale capability. A BMC-based approach also reduces the need for a failover plan, keeps CAPEX low and reduces productivity losses when compute nodes are removed from the main pool due to failure.
Being integrated into the existing on-board firmware and a part of the Life Cycle Management plans of a datacenter enable MegaRAC RSD solutions to help lower Total Cost of Ownership (TCO) significantly. With an integrated approach, there is no need for dedicated servers running RSD software, failover strategies for those servers running RSD management software or for the extra power and cooling required for these servers - just a few of the key TCO-sensitive concerns.
Now OxMs can build racks with flexible server (compute, storage and switch) designs that comply with all industry standards - without asking for any hardware change. Server hardware with manageability founded on the MegaRAC firmware stack is compliant with key industry standards like OCP (Open Compute Project), Scorpio and many OEM-proprietary rack solutions. Most importantly, Rack Scale features can complement all of these standards - immediately, right out of the box.
