    Armonk, New York, Ny, Us
    As a member of IBM Global Services organization I specialized in large MPP (Massively Parallel Processing) UNIX implementations. At the time, a major issue with large data warehouses was the storage provided by IBM. Disk replacement took a skilled administrator and changed the data access patterns as well as left a large amount of storage unprotected while the volumes synced up. Developed a process to replace failed drives with a minimum of exposure and allowing data center personnel to perform the replacement without experienced personnel on site. The program was a supported product provided by IBM at the time of my departure. Part of a “Top Gun” team that worked on high profile customer engagements working directly with IBM engineers to solve unique and complex problems. Recognized by the Global Services consulting practice as the top consultant in the area for 1997.

A DNS naming service was implemented and a Class B network was registered with the InterNIC and used within AutoZone. An enterprise backup solution was also put into place using IBM ADSM. Installed and configured a showcase terabyte data warehouse running DB2/6000 Parallel Edition on the RS/6000 SP platform.
