New four-core server new products recommended Introduction

Quad-core performance is stronger

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; To improve the performance of the computer, the CPU processing capacity is the most important. There are two common ways to improve computing performance: one is to increase the frequency, that is, to allow the CPU to execute more instructions in the same time. However, due to the limitations of chip technology, it is difficult to improve the frequency. Second, the use of multi-core, quad-core processors than the single core/dual computing power. Processor Multi-Core technology is the new growth way of computer performance, is also the most direct and effective method, according to authoritative test showed that quad-core processor than the same frequency dual-core processor application performance increased by more than 50%.

Take the Intel four core Xeon processor Clovertown for example. Clovertown still uses the Intel Core 2 architecture to integrate 4 processor cores on a single wafer, sharing two 4MB L2 Cache. Architecturally, it is very similar to the way a single core processor becomes a Dempsey (5000) processor, which is like two woodcrest (5100) together. Dempsey's computational capacity is less than woodcrest, because in the L2 cache structure is different, two core share a large cache, efficiency is significantly higher than each nuclear exclusive 2MB Cache;4 core of the 5300 series 5100 series, Like two processors together, each two cores use 4MB cache, 8MB cache altogether, this performance is promoted.

Quad-core servers have an advantage in power consumption, such as intel® Xeon 5310 (clovertown 1.6g,fsb 1333mhz,8m cache), L2 Xeon (5320 clovertown, 1.8G,FSB 1333mhz,8m cache) , its subsequent basic power consumption is around 80W, and Intel will release two new four core Xeon processors this year, one of which consumes only 50 watts, much less than the current 80 watts. Low power consumption in addition to reducing user cost, to ensure the stability of the system at the same time, the product design, manufacturing process to put forward more requirements.

Four authorized position still immature

Faced with the application has become mature dual-core server, quad-core server will have what kind of market positioning and sales selling point. The emergence of four nuclear products, reducing the entry threshold of high-end servers, but in the dual-core has not been fully popularized and mature application of the current stage, the four-core early debut is still a lot of questions. The biggest feature of the server is the pursuit of stability, in addition to the need for a very fast CPU, but also need a good, mature application environment to support, in order to achieve the ultimate popularization. The immaturity of the application environment is a limitation of the current four-core server, and the quad-core server needs a necessary transition period.

In addition, the current quad-core server sales price and dual-core server system There is no small gap. Although Intel also introduced a number of prices and dual-core high-end model price similar models, but the server is a system, but also includes hard disk, memory, I/O and other system accessories, various reasons for the whole price, four-core servers than dual-core server more expensive.

Introduction to the latest quad-core servers

With the launch of the Intel four nuclear server chip at the end of last year, the quad-core server market began to warm up. At almost the same time, domestic and foreign manufacturers have announced four nuclear products ready, have launched their own brand of four nuclear servers. According to the server manufacturer of the new quad-core server, to introduce some of the latest four nuclear servers.

1, Dell PowerEdge 2950

The PowerEdge 2950 is configured with up to two 64-bit four core Intel Xeon processors, sharing 2 4MB Two-level cache, up to 2.66GHz per core, up to 32GB ECC DDR-2 SDRAM, and storage servers with the largest 4.5TB internal storage capacity. The latest 64-bit Intel Xeon quad-core processor has a performance improvement of 63% compared to previous generations. 1333MHz front-end bus improves speed. 64-bit memory addressing capabilities provide scalability for memory-intensive applications.

Dual Slots The PowerEdge 2950 delivers a breakthrough next-generation performance that provides optimized internal scalability and rack density. It is perfect for a variety of network infrastructure applications, such as Web, messaging, database, and file/Print service consolidation, both to meet customer performance requirements, but also to provide the necessary hard disk capacity to deal with application growth. All functions harmoniously integrated into the rack-intensive 2U profile specifications.
