Small Systems and Big Iron: Linux on Non-x86 Computers

Discover the options for running Linux on PowerPC, ARM and Itanium.

Of the platforms discussed in this article, Power and especially Itanium both have a questionable future. Although IBM and Intel are committed to developing future generations of their products, the market for high-end proprietary processors has been somewhat eroded by increasingly fast and cheap x86 processors. Many analysts felt that the Tukwila Itanium was underwhelming in comparison to both Power7 and high-end x86 server processors, such as recent Xeon and Opteron chips. IBM expects Power to be a viable platform for a long time, because it still is substantially faster than the x86 alternatives, but even for them, competition is closer than it once was. As a result, Linux support for these platforms probably is going to decline over time, although as long as there is hardware using these architectures, people will be using and developing Linux on them, as has happened with “dead” architectures, such as the DEC Alpha and the HP PA-RISC. ARM, on the other hand, has a bright future, having been dominant on low-power systems for decades and starting to become popular on consumer computer hardware, with constantly improving Linux support.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
