Mainframe computers run large and large corporations around the world with complex and critical computing. Mainframes are fast, intelligent and capable of advanced computing for enterprise IT infrastructure and business goals.
The emergence of newer computing technology has not reduced demand for mainframes, as it has unique advantages over the most reliable business computing solutions
Let's look at the services that favor mainframes in the computing platform and some of their disadvantages too.
High-Computer Computing Advantages
High Computer Calculation: One main feature of mainframe computers is that they can process data and run applications at high speeds. Business computing requires high-speed input / output (I / O) values over a crude calculation speed. The chassis is effectively transported. Furthermore, as business computing requires broad bandwidth connections, designing the mainframe will balance the I / O performance and bandwidth.
Enhanced processing power: Large number of high performance processors from mainframes support mainframe computers. In addition, in contrast to other computers, mainframes delegate I / O with multiple processors, thus limiting the core processor to only processing applications. This feature is unique to mainframes and makes them superior in processing.
Virtualization: The mainframe system can be divided into logical partitions (LPARs, also known as virtual machines). You can run each LPAR server. Thus, a single mainframe machine can work on a "server farm" that uses the number of servers built on a particular platform. Because these virtual machines run on a single processor in one box, mainframes can effectively eliminate the need for many other hardware.
Reliability, Availability, and Serviceability (RAS): RAS features of the computer were often the most important data processing factors. Mainframes have powerful RAS features for both hardware and software.
Mainframe systems are reliable because they are capable of detecting, reporting and restoring system problems. Furthermore, they are able to recover without interrupting the entire work system so most applications are available
Serviceability of large machines means it is relatively easy to detect and diagnose problems, to ease problems in a short time and little
• Security: As mainframes Designed for large organizations where data confidentiality is critical, large-scale computers have extensive capabilities to safely store and protect data. Secure systems for a large number of applications, each providing access to confidential data. Mainframe security often integrates multiple security and monitoring features: user authentication, auditing, access control, and firewalls.
• Excellent scalability: Scalability of a computing platform can also be added to processors, memory and storage. Mainframe computers are known for hardware and software scalability. You can easily perform several different tasks
• Continuous compatibility: Continuous compatibility is one of the popular features of mainframe computers. Supports applications of different ages. Mainframes have been updated many times and continue to work with many combinations of old, new and emerging software.
• Long-lasting performance: Mainframe computers are known for their long-term performance. Mainframe Systems Work For Years and Years Without Major Problems and Time Outsides
Disadvantages of Mainframe Computing
One of the main drawbacks of mainframes is cost. The hardware and software of mainframe computers are clearly expensive. However, security, IT management, virtualization, and so on. Compared to its costs, the costs of the main fleets are significantly reduced.
Secondly, mainframe hardware occupies more space than other computers. This big space can be a restriction for small establishments. But this problem is not as serious as ever. Compared to the previous machines, today's capitals are small.
Finally, cooperation with large-scale computers is required. The mainframe environment can not be operated without special training. However, since a qualified system administrator can serve a large number of large machine users, using the mainframe will significantly reduce the cost of people and thus provide significant staff benefits.
