Solutions and Services for Enterprise-Class Systems

With a special focus on the GNU/Linux Operating System and its kernel, VA Linux provides professional services and support for enterprise-class systems. Specifically, we can provide our clients with Linux kernel improvements, tuning, problem solving support, and high-level consulting services.

With a wealth of knowledge and development experience concerning the GNU/Linux Operating System and kernel (and other UNIX-based OS and kernels as well), VA Linux is a unique group of specialists unlike any other working in the Japanese market. Besides being Linux kernel experts, many of VA Linux's developers have been playeing leading roles in Debian, NetBSD, Linux-HA, OpenLDAP, and Enlightenment development projects. This knowledge, along with our detailed understanding of the issues from the source code level up, allows us to respond to our client's advanced and specialized needs.
VA Linux widely supports implementation of Linux on large-scale and highly reliable systems and specialized and high-spec systems from the kernel level.

Services

1. Fault Analysis Services
   VA Linux offers network fault analysis and solutions to correct or avoid future occurrences. VA Linux provides kernel analysis at the source code level in response to kernel-related system crashes and system hangs. Likewise, we can also offer our expertise in determining whether problems exist with the kernel itself or with applications. We also offer various methods to support the detailed collection of pertinent data at the moment a fault occurs.

2. Performance Analysis Services
   VA Linux offers kernel analysis designed to identify performance bottlenecks and to improve system performance. Through amassing system performance data and using this data to undertake analysis at the kernel source code level, we are able to accurately pinpoint the cause of problems and provide appropriate solutions to our clients. Through probing at the kernel level itself, we are also able to obtain data that cannot be acquired through existing analysis tools.

3. Individually Tailored Kernel Development
   VA Linux can also develop individually tailored functions not found in the pre-existing Linux kernel and also modify the kernel to work with specialized systems. We also can help in such areas as designing networks that employ the pre-existing kernel and also in approaching the broader Open Source development community to help with kernel development to meet our client's specific needs.

4. Consulting
   VA Linux strives to help support our clients when it comes to sorting out the many issues involved in employing the Linux kernel so that it will meet specific system- and product-needs. VA Linux is also dedicated to continuously working to help clients clearly understand areas where (and how) their systems can be improved.
