Upgraded hardware and installed Windows 7 on the minister’s PC. Hewlett-Packard Company, Cupertino, CA 2002 – 2012 Senior Systems Engineer – Business Intelligence Solutions (2006 - 2012) Responsible for the software used to configure, manage, and monitor a new business intelligence platform based on Tandem/HP NonStopTM technology. These systems consist of between 8 to 256 HP C7000 blades. The interconnect is HP ServerNet (similar to Infiniband). Complete systems have up to 1024 Intel Itanium processor cores, 256 storage controllers running on Linux embedded platforms, 5,248 SAS disks, and 76 network switches. My focus was on configuration, testing, and fault detection. Most of my work was developing automation software in C and various scripting languages to configure all of these components. This software was also used to verify the configuration during the manufacturing process and during customer site installation.

Responsible for the design and bring-up of the 2nd generation system. Based on requirements from product management, I sized and configured the building block units for the systems. Consulted with the manufacturing, hardware, operating systems, networking, data base, performance, installation, and support teams to determine the optimal configurations. This newest generation provided more storage and processing power in a smaller, more modular system.

Developed the procedures, documentation, and automation software used by the manufacturing organization to configure and test customer systems. This resulted in faster bring-up at the customer site, higher quality and lower support costs.

Trained and supported the manufacturing personnel in the new procedures. This resulted in faster time to market, higher quality and lower support costs.

After this generation went end-of-life, I worked on a project to port the product to commodity Linux systems using Intel Xeon processors. This resulted in lower cost and more stable configurations. Jonathan R. Marcus Page 2

Senior Systems Engineer – NonStop Enterprise Division (2002 - 2005) Responsible for hardware/software integration of a new generation of Intel Itanium-based HP NonStopTM systems. NonStopTM systems are massively parallel, fully fault tolerant servers used for online transaction processing primarily in stock exchanges, bank ATM networks, and other financial applications. My primary focus was on providing a system prototype environment that developers used to unit test and integrate operating system changes.

Implemented and managed an integration lab with about 25 early prototype systems used by different teams for unit and integration testing. There was a strong emphasis on testing changes to the NonStopTM kernel. Providing developers with a stable bring-up environment resulted in higher quality, better use of developers’ time, lower development cost, and faster time to market.

Installed, managed, and maintained a large number of Debian Linux and Windows Server 2003 systems.

Brought up a second lab with the final, production hardware (50-100 systems).

These labs supported the largest successful continuous integration/test environment used by the NonStop division to date. The tests were written in C and TACL. They included both white box and black box methodologies. (Previously, the division had used primarily waterfall development methodologies.) This resulted in higher quality, better use of developers’ time, lower development cost, and faster time to market. Eternal Systems, Santa Barbara, CA 2001 – 2002

Manager, Field Applications

Responsible for pre-sales/customer technical support of fault tolerant CORBA middleware running on Linux.

Provided consulting and evaluation for prospective customer applications. This made it possible to target sales to prospects that had the best chance of becoming a customer. It also made it possible to explain product benefits to prospective customers.

Provided technical demonstrations at trade shows. This made it possible to introduce our product to prospective customers and consult with them on possible applications. MMC Networks, Sunnyvale, CA 2000 – 2001

Senior Staff Engineer – nPsoft Library Services

Managed integration of networking applications on nP3400 network processor kernel project.

Developed and enforced criteria for releasing integrated development components to test engineers, resulting in a significantly shorter integration and QA phases, higher quality, and faster time to market.

Designed and programmed integration test suite used to validate compliance with the release criteria, leading to significantly reduced integration and QA phases.

Designed and programmed performance test suite used to validate compliance with performance criteria, allowing demonstration of hardware performance capabilities to MMC customers.

Established and operated an integration lab where partially completed hardware and software components could be tested together. I performed both white box and black box testing of various embedded Linux kernels. This resulted in more effective unit testing and reduced the time spent in integration and QA. Tandem Computers, Cupertino, CA 1997 – 2000

Software Designer – ServerNet Clustering Project (1999 - 2000) Managed integration activities on a project to provide high speed clustering of Tandem NonStopTM systems using System Area Network technologies similar to Infiniband.

Established and operated an integration lab where partially completed hardware and software components were tested together. There was a strong emphasis on testing changes to the NonStopTM kernel. This resulted in shorter integration and QA phases, higher quality, and faster time to market.
