IBM's server product line is very complete, from entry-level servers to large servers. Because there are so many products, the classification standards of product series are also varied. In order to let novice friends know about IBM's server product line, I will introduce IBM's series of product classification standards as a whole.
At present, the IBMeServer family generally has four product lines: I series, pSeries, xSeries and Z series. These four series basically include all kinds of server products from entry level to enterprise level, including tower, rack, blade and cabinet in structure. Here is a brief introduction to the positioning of these four series products.
P series:
P series servers run AIX (IBM version of UNIX) and Linux, and there are many products, including p690 with 32 processors, and p6 10, a mid-range and entry-level product. P series is the foundation of IBM Unix server product line. Based on IBM's Power processor, P series has the most extensive Unix product line, from tiny 1 or 2 entry-level server systems to as many as 32 mainframe systems. Structurally, it can be installed on a rack or cabinet. Its Unix product line has unique advantages in scalability. At present, the mainstream P series products are p630 and p650.
X series:
This is IBM's Intel-based server series. This product line of IBM is very rich, including server products at all levels from entry level to enterprise level; In terms of server structure, there are traditional towers, emerging racks and blades, and enterprise cabinets. The X-series product line was launched together with Intel Xeon processors, not the weak P III, and integrated Fibre Channel and Layer 4 to Layer 7 switching functions, so the performance of such servers is usually higher. There are also telecom servers dedicated to the telecom industry.
A series of:
This series of servers is aimed at mid-market customers, such as a department of an enterprise. Customers in this market are most concerned about whether the management is easy and reliable. I-series servers are generally mid-range products, and the most mainstream trend in their customer base is to merge or integrate many small servers into fewer I-series products. For example, the main database is created on an I-series server, the Web front end uses an independent Windows or Intel server, and there is also a file and print server.
Z series:
This is the pillar product of IBM. They are all mainframes, of course, they are all cabinet-style. Such products are aimed at large and medium-sized enterprises that can't tolerate downtime, including big banks, brokers, telecom service providers, and enterprises with large databases and complicated operations.
What is an IBM server?
I. Host system z
The word mainframe originally refers to a large computer system in a very large frame iron box, which is used to distinguish it from smaller small computers and microcomputers. Since about 2000, IBM renamed the mainframe as IBM eServer zSeries. The Z system column means never stop (zero), which is used in critical occasions such as mission-critical applications (24 * 7). IBM mainframe ES9000 (old model) is mostly used in four major domestic banks. At present, the main hosts introduced in IBM official website are IBM z 13 (z 13), IBM Zenterprise BC12 (zbc12) and IBM Zenterprise EC12 (zec6542). Most IBM mainframes now use DB2 databases.
At present, the vast majority of IBM mainframes are used for commercial applications, and the typical industries are banking, insurance, government, transportation, telecommunications and so on. The world's top 50 banks and top 500 enterprises have a large number of business needs, relying on IBM mainframes to perform complex affairs in the world. The advantage of mainframe is massive concurrent I/O, which is conducive to online transactions, and thousands of people log in at the same time. The whole production system can never stop. Of course, the cost of the host is also quite expensive. The cost of any one is calculated by several billion yuan, so those who can afford it are big companies.
The middleware used by mainframe is generally CICS, which is used for back-end database connection and online transaction control on the host. COBOL is the main programming language and JCL is the job control language.
At present, the mainframe is basically monopolized by IBM, and the distance between domestic enterprises and IBM cannot be completed in a day or two.
Second, the minicomputer power supply system
At present, minicomputers mainly refer to power system series. IBM previously maintained two series of iSeries/pSeries in the field of minicomputers, and now it is unified into the Powner series.
I series means business intelligence, which is used in medium-sized enterprises. The operating system is OS /400, the database is mainly DB2 universal database, and the programming language is mainly RPG or COBOL. ? P series means high performance, which is used in small and medium-sized enterprises. The operating system is AIX(IBM's UNIX system), the database is mainly DB2 /ORACLE/SYBASE, and the programming language is uncertain, mostly C/C++/JAVA.
The combined IBM minicomputer is more accurate in positioning. At the same time, enterprises with different needs can provide servers with different performance and different price points.
Iii. IBM PC server system x
X series refers to Intel x86 series CPU, which is used for departmental servers.
IBM xSeries server plays a very important role in IBM server products by providing excellent performance through high-performance Intel Xeon processors. This series is divided into three types of servers, namely, general server, cabinet optimization server, enterprise server and blade server.
IBM eServer xSeries has been acquired by Lenovo. Lenovo's acquisitions include System x rack and tower servers, x86 BladeCenter and x86 Flex System blade servers, and integrated systems with Intel Xeon processors, as well as related software, exchange and maintenance businesses. IBM will keep System z mainframe, Power system, storage, Flex server based on Power, PureApplication and PureData system.
