Project Descriptions

AT&T Wireless, Seattle, WA - Primary project:

Systems: HP, Solaris, RedHat

Problem: Antiquated install and system admin techniques. Mis-configured systems and applications causing long outages. New product rollout without adequate testing. No coordinated monitoring strategy. Many point solutions without full implementation.

Solution: Create organized managed depots for each OS. Create and implement repeatable procedures for maintenance and use of depots. Implement CFEngine to manage application config files and significant OS config files. Extend CFEngine to manage custom and OS packages. Utilize and manage off-shore and outsource scripters and programmers. Assisted design and implementation of Nagios alearting tools.

AT&T Wireless, Seattle, WA - Primary project:

Systems: HP T600s, K-, L-, N- & R-series, PCs with Red Hat Linux, EMC, HP Array, HP SANS,

Problem: 50 HP-UX systems in Seattle and 50 in Dallas were to be kept in sync, one city is backup for the other. The configuration had too much downtime due to software configuration errors and mean time to repair. They needed to upgrade to Version 11.0 by five-system clusters without significant downtime. They need to add 20 systems to each site for new applications. They needed to reduce human error and labor costs in the resulting environment reduce the number of Sys Admins required to manage the environment.

Solution: Configure hardware identical for every cluster. Use customized network based install (HP Ignite/UX) to make system software identical. Custom package third party software, OS customize scripts and application software so it can be part of the Ignite image. Install Ignite image on development system and clone disks (dd) for all systems in the cluster. Shutdown systems, switch disks to the upgraded set. Reboot and do final configure by hand ( IP and hostname ). Result was two hours downtime for upgrade of each cluster and less ongoing downtime for mis-configured software due to human error. All source software maintained in depot for comparison, verification and audit trail. Any system can now be reconstructed from scratch in under 3 hours from the Ignite depot.

Boeing Aircraft, DCAC Renton, WA - Primary Project:

Systems: HP K, H, G series, some R series, PCs with Linux

Problem: DCAC needed to add 100 new systems to the network of 55. The existing organization had an average of 1˝ systems per Sys Admin. There weren't enough Sys Admins in Seattle market to staff the new configuration. Previously each new system, application software and data set took 21 days to install. Downtime and mean time to repair software problems was much too high.

Solution: Increased systems per Sys Admin to ten-to-1 by creating a "management by class" concept where each system was installed identically to all others performing the same function. Created custom network-based install packages for each system class. Developed database-derived custom parameters for each machine. The install scripts call custom PERL scripts, which call Oracle database with IP to find the install time custom options per system. Custom packaged all software (Local, Public domain and commercial COTS) for network installation. Developed a planned installation algorithm based on OpenView Software Distributor’s master and slave depots. Reduced install time to one day for hardware, and four hours for all system software, native and 3rd party applications, and data sets. Changed all system software maintenance to automated network installs to ensure all systems in a given class remained identical. A reduced number of Sys Admins handled all the old and the new systems. Did not need to hire new Sys Admins. Some existing personnel moved to "script design and automated maintenance" to support the new paradigm. Developed web based monitoring system to verify system configuration consistency utilizing standard unix tools.

 

Boeing Aircraft, Tech Services, Bellevue, WA - Primary Project

Problem: Too many OS and product revisions and too few people. Solution: Architect, develop and implement software management and certification strategies for company-wide use of HP-UX in Boeing's "Technical Support for HP-UX" group. This included developing strategies for maintaining depots of multiple revisions of HP-UX 9.x, 10.x and 11.x and associated system patches. Acted as the liaison between Boeing and Hewlett Packard for system patch testing, new product evaluation and technical information. Developed standards for custom packaging local and third party software for inclusion in the standard depots. Automated the depot management and verification processes.
