IBM Power Systems Availability and Security

The two most defining characteristics of IBM Power Systems have to be their availability and security. While many organizations initially choose Power Systems for a reason like increased utilization or cutting-edge virtualization technologies, it is the way in which Power Systems are reliable and reduce risk that often keeps them coming back.

Power Systems Availability

What is it about IBM Power Systems that gives them their reputation for high availability? It starts with industry surveys and user experiences. Time and again, Power Systems rank higher than other platforms in terms of availability.

In addition, Power Systems can run on a 24 by 7 basis with very little intervention on the part of systems personnel. Depending on the particular Power Systems implementation, unplanned outages can be minimized or even eliminated. Virtualization technology like PowerVM means that even planned outages can be a thing of the past.

Some of the availability comes from the kernel. The IBM i series kernel has fewer potential points of failure. In addition, it is less prone to error due to users or due to IT staff. Even in Windows and Linus implementations, Power Systems offers a number of availability features.

Availability really comes to the fore with IBM implementations, however. The microelectronics technology used in the kernel is matched directly with the hardware, making for a tight and secure fit. Specifically, RAS (reliability, availability and serviceability) technologies in i are supported in the physical configuration of Power Systems.

Power Systems Security

IBM Power Systems security also shines when used in conjunction with IBM i. IBM i is known to be one of the most secure OS ever created. Malware incidents are unheard of when it comes to IBM i, and security violations into the OS are nearly as rare.

The statistics back the security of Power Systems up. The U.S. National Vulnerability Database is a repository of known security vulnerabilities, and is operated by the National Institute of Standards and Technology. Since they began collecting vulnerability statistics in 1992, they have not recorded any vulnerabilities for IBM i. In addition, there are no known viruses native to i.

This is due, at least in part, to the distinctive object-based structure of IBM i. The way that i encapsulates objects creates a strict data and system code control, which means it’s nearly impossible for unauthorized instructions to run.
Add in IP security and detection systems, and the IBM i series is one of the most secure computing environments you can find.

If your organization values availability and security, IBM Power Systems running i Series is the right fit for your needs.

Energy Efficient Servers

energy efficient serversRefreshing servers on an ongoing basis can reduce costs to the datacenter. Rather than put off capital expenditures and extend server life cycles (buy and hold strategy), organizations faced with sharp budget challenges should consider aggressively seeking financial deals that allow them to upgrade their servers with today's technology.
