Matt Ahrens
Matt Ahrens  

Matt Ahrens co-founded the ZFS project in 2001, and is now the ZFS engineering team lead. He has a degree in computer science from Brown University.


Chris Armes
Chris Armes  

Chris is the Director of Solaris Revenue Products Engineering (RPE) for EMEA, based out of the UK. RPE is part of the Solaris engineering organisation, within Sun's Software business unit. The RPE team are primarily focused on the ongoing sustaining engineering of the shipping releases of Solaris, although a good portion of the time is also spent working on the next release of Solaris. The tight integration and co-operation with the New Product Engineering (NPE) team is one of the key success factors of Solaris.

The team is very much a true example of global engineering being split equally across the three geographic regions that SMI operates in - AMER, EMEA and APAC. Chris himself has members of his team in each one of those three geographies. This he is sure is one of the factors that leads his wife to believe that the UK is just another hotel he stays in for a time during the year.

The RPE team provide 24 x 7 source code engineering level expertise on the Solaris operating system. If you have an issue that needs code level expertise, including source code changes, delivered at 2am Pacific time on Christmas Day its likely you'll be working with someone in the Solaris RPE team. The team also owns a large number of the areas within Solaris that Sun is no longer doing active development on, such as UFS and SVM. This combines with working closely with our NPE colleagues on the latest and greatest parts of Solaris like ZFS and FMA makes the RPE organisation a particularly challenging and exciting team to be part of.

Chris joined Sun in 1999 and has over 16 years of experience in the industry including software engineering of operating systems and application software for military usage. He has a BSc (HONS) degree in Computing Science from Staffordshire University. When he is not working he is married with two children, a dog, a cat and rabbit and enjoys Amateur Dramatics in what little spare time he has left.

Aaron Dailey
Aaron Dailey  

Professionally, I've been an engineer nearly twenty years. I graduated from University of Virginia computer science department. While I can't claim to have worked on a punch card machine, they did wheel out the last punch card machine out of the computer center my first year at UVA.

Since then, I've worked in several different companies, mostly storage and/or Unix related, from IBM to Adaptec, to a startup called Chaparral (now part of Dot Hill), and now Sun. All were good in their own ways, although I do particularly enjoy Sun.

In early 2006 I had an opportunity to come to China to do some training for several months. I jumped at the idea, and liked it enough that I decided to stay. I spend time outside of work studying an MBA at Peking University. I feel very fortunate to have met my wife here, a wonderful Chinese woman.

Sunay Tripathi
SunayTripathi  

Sunay is a Sun Distinguished Engineer in Solaris Core OS group and has been with Solaris group for 10 years. He has designed, developed and led projects in SUN Solaris kernel/network environment to provide new functionality, performance, and scalability.

He is the Architect for the new stack in Solaris 10 and is currently the architect for Solaris Network Virtualization and Resource Control (project Crossbow). The new architecture allows the system to vertically partition the workload using an IP classifier-based lock-less design. It significantly reduces the overheads of synchronization and cross communication between CPUs which significantly increases performance and scalability.

Sunay was one of the key people for Network Cache and Accelerator (NCA), which provides alternate path from sockets layer all the way down to device driver and gave almost 2 times better performance for web type workloads over the pre FireEngine Solaris stack.
