Intel Announces 3 Atom S1200 Low Power Server SoCs: S1220, S1240 and S1260

Intel has recently introduced the Intel Atom S1200 product family (Codename: Centerton) targeting high-density microservers (1000+ nodes per rack), and energy-efficient storage and networking systems. These new processors includes features such as error code correction, 64-bit support, and virtualization technologies required for use inside data centers, and consume as low as 6.1 watts. Three models are currently available: Intel Atom S1220 @ 1.6 GHz – TDP 8.1 Watts Intel Atom S1240 @ 1.6 GHz – TDP 6.1Watts Intel Atom S1260 @2.0 GHz – TDP 8.5Watts The SoCs include 2 physical cores and 4 threads enabled with Hyper-Threading Technology. The SoCs also include 64-bit support, a memory controller supporting up to 8GB of DDR3 memory, Intel Virtualization Technologies (Intel VT), 8 lanes of PCI Express 2.0, Error-Correcting Code (ECC) support, and other I/O interfaces integrated from Intel chipsets. Atom S1200 processors are manufactured using 32nm process technology. Intel also announced that […]

Applied Micro X-Gene 64-Bit ARMv8 Server-on-Chip Presentation

Applied Micro Showcases World’s First 64-bit ARMv8 Core at ARM Techcon 2011, Santa Clara California. The day ARM announced the first 64-bit ARMv8 instruction set architecture, AppliedMicro unveiled the launch of the industry’s first 64-bit ARM “Server-on-a-Chip” solution. Most of the presentation is used to explain the competitive advantage this platform would bring including TCO reduced by 30%. There is also an (underwhelming) demonstration of X-Gene based on Xilinx Virtex-6 FPGA running Server SoC consisting of ARM-64 CPU complex, coherent CPU fabric, high performance I/O network, memory subsystem along with fully functional SoC subsystem. The FPGA platform and tools will be available for customer evaluation by the first half of 2012. Redhat will be in charge of implementing ARMv8 support in Linux and this will be part of Fedora for ARM in the future. The platform will run LAMP: Linux, Apache, MySQL and Perl/PHP/Python. The silicon will be available in […]

Bootloader to OS with Unified Extensible Firmware Interface (UEFI)

Unified Extensible Firmware Interface (UEFI) is a specification detailing an interface that helps hand off control of the system for the pre-boot environment (i.e.: after the system is powered on, but before the operating system starts) to an operating system, such as Windows or Linux. UEFI aims to provides a clean interface between operating systems and platform firmware at boot time, and supports an architecture-independent mechanism for initializing add-in cards. UEFI will overtime replace vendor-specific BIOS. It also allows for fast boot and support for large hard drives (> 2.2 TB). There are several documents fully defining the UEFI Specification, API and testing requirements: The UEFI Specification (version 2.3.1) describes an interface between the operating system (OS) and the platform firmware. It describes the requirements for the following components, services and protocols: Boot Manager Protocols – Compression Algorithm Specification EFI System Table Protocols – ACPI Protocols GUID Partition Table (GPT) […]
