For example, the difference between workgroup servers and department-level servers is not too obvious, and some are simply referred to as &#8220;workgroup\/department&#8221; servers.<\/p>\n<h2 style=\"padding-left: 40px;\"><span class=\"ez-toc-section\" id=\"By_Architecture_chip\"><\/span><b><\/b><span style=\"font-size: 14pt;\"><strong><b>By Architecture (chip)<\/b><\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>According to the structure of servers, they can be divided into CISC (Complex Instruction Set\u00a0Computing) architecture servers and RISC (Reduced Instruction Set\u00a0Computing) architecture servers.<\/p>\n<p>IA architecture servers (Intel Architecture Server) &#8211; commonly referred to as PC servers, using x86 (CISC) chips and mainly using Windows NT\/Windows2000, Linux, FreeBSD, and other operating systems servers, such as Intel PentiumIII (P4) and Intel (P4) Xeon, etc.<\/p>\n<p>RISC architecture servers refer to servers with non-Intel architecture technology, using RISC chips and mainly UNIX operating systems, such as SUN&#8217;s SPARC, HP&#8217;s PA-RISC, DEC&#8217;s Alpha chip, SGI&#8217;s MIPS, etc.<\/p>\n<p>Since the performance and price of RISC architecture servers are much higher than that of CISC architecture servers.

First, placing servers does not take up too much space. Rack servers are neatly disposed of in racks without wasting space. Secondly, cables and other connections can also be neatly put away in the rack. Power cables and LAN cables can all be laid out in the rack, so it can reduce the situation of connections piled up on the floor, thus preventing accidents such as kicking off wires. The specified dimensions are the width of the server (48.26 cm = 19 inches) and the height (a multiple of 4.445 cm). Since the width is 19 inches, so sometimes the rack that meets this requirement is also called &#8220;19-inch Rack&#8221;.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-2674\" src=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2022\/08\/blade-server-300x225.jpg\" alt=\"Blade Server\" width=\"436\" height=\"327\" srcset=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2022\/08\/blade-server-300x225.jpg 300w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2022\/08\/blade-server.jpg 600w\" sizes=\"(max-width: 436px) 100vw, 436px\" \/><\/p>\n<p style=\"text-align: center;\"><strong><span style=\"font-size: 10pt;\">Blade Server<\/span><\/strong><\/p>\n<p>Blade servers are a low-cost server platform called HAHD (High Availability High Density), designed for specific applications and High-Density computing environments.
