Significant Achievement

Member of team that achieved significant capital cost savings by consolidating workload of several

smaller servers/workstations to fewer, larger server cluster environments. Results included faster, more

efficient systems and elimination of 50 UNIX workstations.

Member of San Migration Project that identified files systems on older disk arrays on servers that needed

to be migrated to new disk arrays. Supplied information needed to make disk visible to the servers from

new disk array. Responsible for verifying all file systems were properly identified, the new disks were

visible, the required disk space was available, migrating data from old disk to new disk, coordinating with

other groups (users, application support, DBAs) using servers of work activity and scheduled outages.

beta version of their ECS GUI product that communicated with Control-M on both the IBM Mainframe

and HP-UX server. The application used an Informix database that I worked with the DBA on setting up

backups for the logical logs and the database.
