Linux has proven itself to be a versatile solution across a variety of hardware architectures to support workloads ranging from basic infrastructure services to enterprise-class database deployments. Today, Linux is commonly found operating in some capacity within most larger organizations, and over time, it has captured many of the same workloads that previously were deployed aboard RISC platforms running Unix operating systems.

The powerful tape technology can address data security with tape encryption as well as long term data protection.
Discover what disk and tape really cost -- and which solution provides lower total cost of ownership and optimizes energy use for your organization
The Clipper Group explores the truth behind the myths of tape, digging into the misconceptions in the disk vs. tape debate.
Over two thirds of disk-only users look to add tape back into storage infrastructure according to recent survey.
Neterion has built new 10 Gigabit Ethernet adapters with support for emerging I/O virtualization standards that aim to improve the performance of applications running on virtual servers. The adapters also provide the isolation necessary to reboot one virtual machine without affecting the other virtual machines on a physical server.
Neterion’s third-generation X3100 Series adapters, unveiled Monday at VMworld in Cannes, France, are the first to support the SR-IOV 1.0 industry standard for single-root I/O virtualization, which lets a single adapter act like multiple physical adapters within a virtualized server, according to Neterion.
The standard, developed by the PCI-SIG electronics industry consortium, will help prevent potential hardware and software problems that could arise when vendors build virtualization-enabled adapters that aren’t compatible with each other, says analyst Nik Simpson of the Burton Group. Simpson expects more vendors to follow suit by building devices compliant with the SR-IOV standard.
“There’s bound to be problems when you’ve got multiple companies doing adapter virtualization through nonstandard means,” Simpson says. “Anything that involves standardization is good for customers and is good for the industry as a whole.”
One common problem with server virtualization is that the hypervisor has to be involved in every I/O transaction, creating a bottleneck, according to Simpson. Neterion’s new adapter and future ones that take advantage of the single-root standard will minimize the hypervisor’s involvement, thus improving performance. Moreover, the ability to reboot a virtual machine without impacting the other virtual machines accessing a physical device “gives you a very flexible solution for virtualizing I/O,” Simpson says. “It’s going to become increasingly common.”
Neterion is also supporting multiroot I/O virtualization, which is for blade servers, while single-root is for conventional servers. (Compare blade server products.) A proposed PCI-SIG standard on multiroot may be approved later this year.
