Job Profile: Systems Engineer / Architect / DB2 Engineer

Responsibilities:

  • Successfully delivered IBM PowerVM Virtualized Systems for DB2 migration project. Following are key achievements.
  • Researched multiple technologies from many hardware and software vendors to design robust infrastructure for hosting DB2 databases belonging to all DOL agencies.
  • Designed robust infrastructure using IBM Power 6-570 Systems after evaluating requirements from DOL agencies.
  • Implemented hardware solution as per design and delivered by project deadlines.
  • Documented project manuals, baselines, and architecture diagrams. Delivered to customer by project deadlines.
  • Newer system's throughput exceeds customer's expectations.
  • Isolated every agency in separate environments which avoids interference. Earlier environment was common server for all agencies and some agencies were getting below average performance because of resource used by other agencies
  • Earlier storage was using ISCSI as communication medium which delivered slower I/O throughput. Newer storage is communicating using fiber channel medium and provides higher I/O in magnitude of hundreds when compared with earlier ISCSI storage. Newer storage is also fault tolerant.
  • Earlier systems were not fault tolerant. Newer systems have multiple level of fault tolerant at component and server level. Newer systems can failover at site and across site. HACMP technology is used at site to provide fault tolerant and HADR technology is used to provide fault tolerant across site
  • Trained production support staff in newer technologies used in newer infrastructure in order to help them maintain this infrastructure in the future
  • Newer infrastructure uses virtualization technology which saves power and space in the data center.
  • Newer infrastructure is highly scalable. PowerVM technology allows server resources to scale far beyond allocated limits without intervention from system administrators. Older systems had hard set limits on resources which needed downtime and intervention from system administrators to scale.
  • Newer System has better management and monitoring tools which makes it easier to manage and monitor system as compared to older systems
  • Successfully migrated DB2 databases for all agencies of DOL from 8.2 to 9.5. Coordinated with application teams from all agencies to successfully test and migrate databases in production.
  • Installed and configured IBM Optim Performance Manager in order to monitor all DB2 databases.
  • Successfully delivered VMWare virtualized environment for IBM WebSphere Application Server migration project. Following are key achievements.
  • Designed newer infrastructure using HP Enclosure, HP Blades, VMWare vSphere ESX for virtualization, and NetApp 3170 storage for hosting all instances of applications of DOL on IBM WebSphere Application Server.
  • Implemented hardware solution as per design and delivered by project deadlines.
  • Documented project manuals, baselines, and architecture diagrams. Delivered to customer by project deadlines.
  • Newer system's throughput exceeds customer's expectations.
  • Earlier systems were standalone dell servers and were not fault tolerant. Newer systems have multiple level of fault tolerant at component and server level. Newer systems can failover at site and across site. VMotion technology is used at site to provide fault tolerant.
  • Trained production support staff in newer technologies used in newer infrastructure in order to help them maintain this infrastructure in the future
  • Newer infrastructure uses virtualization technology which saves power and space in the data center.
  • Newer infrastructure is highly scalable. VSphere technology allows server resources to be scaled dynamically.
  • Newer System has better management and monitoring tools which makes it easier to manage and monitor system as compared to older systems
