 1. What a Lustre File System Is The Lustre architecture is a storage architecture for clusters. The central component of the Lustre architecture is the Lustre file system, which is supported on the Linux operating system and provides a POSIX * standard-compliant UNIX file system interface. The Lustre storage architecture is used for many different kinds of clusters. It is best known for powering many of the largest high-performance computing (HPC) clusters worldwide, with tens of thousands of client systems, petabytes (PiB) of storage and hundreds of gigabytes per second (GB/sec) of I/O throughput. Many HPC site use a Lustre file system as a site-wide global file system, serving dozens of clusters. While a Lustre file system can function in many work environments, it is not necessarily the best choice for all applications. It is best suited for uses that exceed the capacity that a single server can provide , though in some use cases, a Lustre file system can perform better with a ...

SOCKS performs at Layer 5 of the OSI model ( the session layer , an intermediate layer between the presentation layer and the transport layer). SOCKS server accepts incoming client connection on TCP port 1080 . 本地开启的是SOCKS5 Server，启用系统代理后，浏览器使用系统HTTP代理连接上SOCKS5 Server。 SOCKS5 Server支持的不止HTTP代理。 Comparison to HTTP proxying SOCKS operates at a lower level than HTTP proxying : SOCKS uses a handshake protocol to inform the proxy software about the connection that the client is trying to make, and then acts as transparently as possible, whereas a regular proxy may interpret and rewrite headers (say, to employ another underlying protocol, such as FTP; however, an HTTP proxy simply forwards an HTTP request to the desired HTTP server). Though HTTP proxying has a different usage model in mind, the CONNECT method allows for forwarding TCP connections; however, SOCKS proxies can also forward UDP traffic and work in reverse, while HTTP proxies cannot. HTTP proxies are traditionally more aware of ...
