Sun announced the launch of a new generation of http://www.aliyun.com/zixun/aggregation/13737.html "> Blade server Sun Blade 6000 Modular System, 　　This is not only the Sun's first server with Intel processors, but also a further breakthrough in I/O transfer and memory capacity. Breakthrough one: I/O transfer capacity up to 142Gbps Sun Blade 600 ...

Recently, IBM upgraded some models of the power system product line, including upgrading memory and I/O to the starter model, and increasing the number of processing cores for high-end models. The entry-level models for this upgrade include Power710 and 730, which were released in August 2010 with 2U architecture, which makes it difficult to distinguish between the two. Where Power710 supports a single POWER7 processor and 8 DDR3 memory slots, the upgraded Power710 can support one 16GB RAM, maximum memory ...

Virtualization is the current hot topic, but its core problem is also virtual. That is, the operating system is usually "considered" to be running independently on the computer. But in fact there are several different operating systems that share a single computer, each operating system is called a system mirror (systems Image,si). Because the memory snap-in is integrated on the mainstream computer, this virtualization is entirely feasible on the mainstream computer. This technique is not particularly popular, however, because it simulates all the devices in the computer and has a great impact on performance. The recent development of software and hardware technology to improve ...

Lucero, a technology director at Vmpower, a consultancy at the beginning of 2007, said: "The number of blade network cards is limited and does not apply to virtualization." He said that in the configuration of the server virtualization application, Vmpower recommended to install more than one network card, "never less than 6 network cards (ports), up to 14." 　　"There are similar restrictions on the Fibre Channel (FC) and memory capacity on the blades compared to the rack-top servers. Similarly, there are users in the country are also suitable for the blade server ...

Intermediary transaction SEO diagnosis Taobao guest owners buy Cloud host technology Hall believe that for the education Network and 169 of the network users, proxy server is again familiar. Having a good agent not only can access most of the resources on the Internet, but also can sometimes improve the speed of the network, save us a lot of money. So what is a proxy server, what is the benefit of it, how do we use it? Here we will explain: first, what is a proxy server? Agent server (proxy server), from whose name ...

The age of mass data is coming. Data volumes are growing rapidly, according to the latest study by IDC, an analyst, and the 2011 global data volume broke through 1.8ZB, growing 9 times times faster in 5 years and managing more than 50 times times the amount of data being managed. At the same time, the cloud computing market has matured and developed very quickly, in the massive data and cloud of double attack, data storage is facing severe challenges, we see that storage has become a weak link in the enterprise, if not pay attention to so lost will not only opportunities. One of the biggest picks of cloud computing ...

When we talk about production environments, each administrator should consider all possible single points of failure (SPOF) and resilience in the schema. Here, we will explore the VIOS and LPAR networks, which eliminates the most likely SPOF of the network, providing a separate network that can quickly communicate with the backup server to access applications and databases. This architecture has been widely used, where users can access the server 24x7, and administrators can back up data without affecting user bandwidth. Figure 1. Schema diagram in this architecture, ...

Server performance is becoming more robust as CPUs, memory, and storage technology evolve. For example, CPU manufacturer Tilera Corp. recently released the TILE64 family multi-core processor. The processor contains 64 separate processor cores, and each core is a fully functional processor. Each core contains L1 and L2 caching, which means that these cores can support a full operating system (OS) independently. The physical server technology has elevated memory management to a new level. For example, HP Proliant DL580 G7 server, with 64 ...

Designing 1 applications doesn't seem to be difficult, but it's not easy to achieve the optimal performance of the system. There are many choices in development tools, database design, application structure, query design, interface selection, and so on, depending on the specific application requirements and the skills of the development team. This article takes SQL Server as an example, discusses the application performance optimization techniques from the perspective of the background database, and gives some useful suggestions. 1 database design to achieve optimal performance in a good SQL Server scenario, the key is to have 1 ...

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...
