Review: Virtuozzo for Linux 3.0
Virtualization is sweeping the nation. Well, maybe not the nation, but it's a big hit with data centers and organizations that need to consolidate systems and streamline management. With so many virtualization applications on the market, which one to choose? SWsoft's Virtuozzo is strong contender. I reviewed Virtuozzo 3.0 for Linux, and it's definitely one of the best options you can choose to centralize server management and consolidate workloads onto fewer systems.
Unlike some virtualization solutions, Virtuozzo doesn't present a software virtual machine to an operating system to run multiple OSes on the same system. Instead, Virtuozzo uses OS-level virtualization to partition the system into separate Virtual Private Servers (VPS) -- similar to Solaris Zones or Linux-VServer.
This means that Virtuozzo for Linux can run several Linux VPSes, but unlike VMware, it doesn't run multiple OSes on the same server. That might seem to limit your choices somewhat, but many organizations have no interest in running different OSes in virtual containers -- they just need a way to improve hardware utilization through server consolidation, and make system management easier. Virtuozzo does do that very well.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
