Systems/Software Engineer V / SW Engineer QA III

o    Architect and developer of HP Automation Infrastructure (“AI”) built around VMware ESX / Labman and HP MSA and EVA storage arrays - HP Storage iBRIX product family. Wrote extensive infrastructure framework to automatically provision, deploy and manage VM clusters and physical machines in the “cloud”, established communications between the system and users, provided Network control, and automatically undeploy and unprovision resources. Automatic clusters suspend / poweroff in case of error and save state for manual analysis. Set up and managed system datastore on top of HP’s MSA and EVA storage products. Created distributed resource pools of components (VMs, physical servers, iSCSI storage, networks, test suites) for automatic provisioning. Infrastructure in the AI was built dynamically from these components based on high-level abstraction description. Users could choose which components to use based on datastore (if user didn’t care, it was chosen automatically), etc.:

o    Developed system to set up and manage clusters (or just single machines) via scripts supplied by users. AI supports user scripts written in Python, Perl, C/C++, and Java. Used SWIG locally or on remote machines (physical and virtual). Used STAF (Software Testing Automation Framework – OpenSource) extensively. Adaptable to any test harness. The AI also used many other OpenSource projects. Generate extensive reports. Wrote facilities to automatically write results to MySQL, email reports, schedule resources and deployments, etc. Designed high level description file formats for provisioning abstraction, testing, and other purposes. Facilitated meetings between teams/groups. Developed presentations for management.

o    Developed automated OS install on bare metal and VMs

o    Developed major sections of the AI including the scheduler, VM interfaces, Cron, Resource Scheduler/Manager, Network Control, user command line interfaces, user configuration files’ format, checkpointing, logging/debugging, etc. Works with both Virtual and physical machine clusters. Developed VMware Labman interface for automating suites on VM Clusters (Linux and Windows). Designed and wrote facilities to automatically generate and email reports. Used with many third-party testing harnesses (such as QA run, fsSmoke, Mantis) and facilitates working with other test harnesses. Designed to be able to test pretty much any kind of product, software or hardware.

o    The AI saved hundreds of man-hours per month by creating automated Windows parallel build environment. This allowed product builds to be completely automated for multiple users simultaneously. Used Cygwin and OpenSSH and leveraged work done by others. Shared this configuration so other engineers could use it as a template for their own build servers.

o    This saved developers (automated testing) and managers (automated reporting) time and frustration by automating tests via a web interface written using EXT JS.

o    Collaborated with QA developers to deploy File System Smoke Test Harness (“fsSmoke”) in a virtual environment using the AI Framework. Collaborated with QA Developers to migrate their test harnesses to the AI.

Wrote and distributed procedures (“How-Tos”) on subjects for own team, other teams, and entire division. Fixed other engineers’ issues with their Linux and Windows development and test environments. Maintained team’s Linux servers and fixed server and network problems to keep the team productive. Taught other engineers how to use new features in our products, etc. Help decide with team members do which tasks, etc.
