Overview:
IBM Power servers
details:
IBM minicomputer general techniques used are: RISC-based multi-processor architecture, the magnitude mega byte cache, a few gigabytes of RAM, using hundreds of GB specialized I I / O processor / O channels on the disk storage, as well as a dedicated management processor. They are smaller in size and is air-cooled, so the customer site there is no particular cooling duct requirements.
characteristic
Minicomputer with the ordinary server (that is often said that the PC-SERVER) is very different, the most important point is the high minicomputer RAS (Reliability, Availability, Serviceability high reliability, high availability, serviceability) characteristic.
RAS is Reliability, Availability, Serviceability abbreviation of three English words, they reflect the high reliability of the computer, high-availability, high service of three well-known characteristics of their specific meanings are as follows:
High reliability (Reliability): the computer can continue to run, never stop.
High Availability (Availability): Important resource has backup; able to detect potential problems to occur, and can transfer task on which the running to other resources, to reduce downtime and maintain continuous operation of production; maintenance and real-time online delayed maintenance functions.
High service (Serviceability): real-time online diagnostics to pinpoint the fundamental problem, so that the accuracy of the quick fix.
