In this fast growing Internet environment of things, many things that we do every day, like checking accounts mail, posting on social media sites, browsing web pages, and web search portals or index-not compute intensive. They do however; have high demands I / O and memory footprint. IT architects working at this scale generally use cluster technology to perform massively parallel workloads that distribute data across many nodes, often in cloud computing environments.
ARM has been leading this new trend of low power, high density and parallel computing with micro servers hyper-scale meeting the needs of these growing markets. ARM Cortex v8a is the 64-bit SoC architecture that most hardware server vendors have been using in building their tissue hyper-scale micro-servers. The challenge here is that ARM processors are built in wide varieties and forms of micro-servers with varying aspects of system functionality. As a result of this variability in both functions of the processor system; software development system was expensive especially as we take into account development needs of products, quality and deployment.
ARM-based system architecture of the server (SABS) specifications are part of the ARM strategy to address this variability spoken. SABS specifies the hardware architecture system that the server system software such as operating systems, hypervisors and firmware can count. Therefore, addressing characteristics of the CPU and the main aspects of the system architecture. The main objective here is to ensure sufficient standard system architecture to allow a single image of the operating system built to work properly on all equipment complies with the specification. A model based on the driver for the capabilities of the advanced platform is still possible, but beyond the scope of SABS. In short, with SABS, the software ecosystem will gain the following key features :.
- Single OS image for all servers ARMv8-A
- Application developers can target a single OS image for all servers ARMv8-A target platform
- OS / firmware vendors have well defined.
Another key advantage of SABS is that it eliminates the need for software emulation of the functionality of critical key system for software performance as system startup, interrupts, timers, I / O, etc.
standardization is an excellent tool for innovation providing compliant firmware and infrastructure of the operating system for the -platform against portability. thus enabling IT to choose from a variety of offerings based on ARM that match specific application workloads and IT budget.
Citrix was a member of Linaro Enterprise Group (LEG) and has been engaged in a collaborative effort across ARM server and operating system vendors to achieve this level of standardization of ARM v8a 64-bit server platforms. This collaborative effort involved systems designers, architects and technologist AMD, Applied Micro, Broadcom, Canonical, Cavium, Citrix, Dell, HP, Linaro, Microsoft, Red Hat, SUSE and Texas Instruments
the SABS is a basic specification which will evolve over time; including additional features such as live migration of virtual machines between systems based ARMv8A architecture. Firmware, OS and virtualization companies such as Citrix SABS uses to target logical progression of platforms to accelerate the development and ensure cross-platform portability.
Citrix Xen Hypervisor brought the project to the 64-bit architecture ARMv8A and has been actively engaged with suppliers ARM server for testing and verification of the Xen port on ARM ecosystem. Citrix CloudPlatform Apache come with the backing of the box for the supply of bare metal ARM micro servers. Citrix has been engaged in various levels of testing and integration efforts with ARM micro-server suppliers so that our clients will have a full stack of solutions for the management and orchestration of the workload for both servers and ARM physicalized virtualized data centers and cloud based.
