VA Linux is a company of open source experts who keep on working toward the growth of open source technologies. Besides being Linux kernel experts, many of VA Linux's developers have been taking a lead role in OpenStack, KVM, Xen and Open vSwitch projects. This knowledge, along with our detailed understanding of issues from the source code level up, allows us to respond to our client's advanced and specialized needs.
VA Quest offers failure analysis solutions for mission-critical systems using open source software in complex IT client/server environments from the code-level with crash dump analysis, failure analysis, proposal to avoid failures and providing correct patches.
Kernel analysis at the source code level in response to kernel-related system crashes and system hangs. Likewise, we can offer our expertise in determining whether problems exist with the kernel itself or with applications. We also provide various methods to correct or avoid future occurrences for many open source software such as KVM and Xen.
Open source software such as KVM, Xen, CloudStack and OpenStack analysis designed to identify performance bottlenecks and to improve system performance.
We examine issues, clarify problems, suggest points of improvement and support the roll-out of virtualization and cloud computing technology.
Technical and industry trend analysis of open source software including Linux kernel, virtualization and cloud computing.
We support to design and development for mission-critical systems, cloud computing infrastructures and server/network virtualization with functional improvement, tuning and OSS architecture/missing functions development.
Develop individually tailored functions not found in the pre-existing Linux kernel and also modify the kernel to work with specialized systems.
We can support the system development by applying open source software for virtualization such as KVM and Xen to operate large-scale and/or specialized high-end enterprise systems.
We are contributing to develop OpenStack architecture as a member of the OpenStack project. Particularly, we are the sixth most contributive company in the world about "Quantum" (as of April 2012). Our expertise allows us to support building cloud computing infrastructure by maximizing the flexibility of OSS technologies.
We provide instructive proposals, research, analysis, verification and evaluation reports to build system infrastructure with open source software.VA Linux strives to help support our clients when it comes to sorting out the many issues involved in employing Linux kernel and the other open source software so that it will meet specific system- and product-needs. We are also dedicated to continuously working to help clients clearly understand areas where/how their system can be improved.
Our professional services will be available to support a wide range of open source technologies.

VA Storage is a linux-based storage virtualization software which provides logical volumes (linux block devices) to users by aggregating disks over a network.
VA Storage is verified as Citrix Ready®
Citrix Ready Xchange Marketplace:
※ VA Storage can be sold only in Japan.
A logical volume won't lose its data in VA Storage whether any physical disk or storage server in the storage pool has broken.
Increasing overall system performance by removing I/O bottlenecks, increasing system bandwidth, and reducing system latency.
Optimizing system performance ensures to keep the overall system working as a means of agent monitoring, disk patrol and logical volume error monitoring.
VA Storage provides scale-out capacity and performance as needed. Load balancing and thin provisioning provide for easy administration and reduce total costs.
