Nfs Data

The network filesystem (nfs,network file system) is a mechanism by which partitions (directories) on a remote host are mounted over the network to the local system, which enables users to share partitions (directories) on the remote host, as if they were operating on the local system, by supporting the network file system. . In the development of embedded Linux, developers need to do all the software development on the Linux server, cross compile, the general FTP way to download the executable file to the embedded system operation, but this way not only effective ...

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 ...

Sharing photos is already one of the most popular features on Facebook. So far, users have uploaded more than 1.5 billion photos, making Facebook the biggest photo-sharing site. For each uploaded photo, Facebook generates and stores four images of different sizes, which translates into 6 billion photos, with a total capacity of over 1.5PB. At present, the rate of 2.2 million new photos per week increases, which is equivalent to an additional 25TB of storage per week. And in the peak per second need transmission ...

Today, we are frequently exposed to the term "large data". But the industry still lacks a standardized definition of what big data is. So what does big data mean to the data storage infrastructure? The definition of large data by the Enterprise Strategy Group (ESG) is "a dataset that is larger than the conventional processing capacity boundary, which makes you have to resort to unconventional means." "In simple terms, we can use the word big data on any data collection that breaks through the traditional it processing to support the day-to-day operational capabilities of the business." These boundaries may appear in the following ...

With Intel's drive, IT system communications bandwidth and computing power follow Molfa to record highs, maintaining a doubling of growth rates every 12-18 months. At the same time, IDC's latest "Digital Universe" study predicts that data will grow faster than Moore's law, reaching 1.8ZB in 2011, and that the company will manage 50 times times the current amount of data over the next 10 years, and file volumes will increase 75 times times. 　　Under the background of the rapid expansion of the digital universe, the concept of "big data" came into being. Detailed explanation big ...

MPICH2 provides a platform for parallel and distributed processing of large data under existing hardware and software architectures. This article will describe how to build a high-performance distributed parallel computing environment based on MPICH2 in Linux systems. MPI (Message passing Interface) is a messaging standard developed by the MPI Committee, which defines a series of programming interfaces for interprocess communication in a distributed environment, currently with MPI-1 and MPI-2 two versions. MPICH2 ...
