Mainframe Data Center 

Prudential Securities mainframe Data Center consisted of three large IBM Mainframe processors,  a large DASD environment,  Six Storage Tek Tape Library Silos, each supporting up to 6000 tapes, and three front end processors.  Mr. Carapola managed the creation of this Data Center from its initial concept through completion of cutover. Some major components of this effort included:

• Design of the physical environment including redundant power distribution, chilled water cooling, cable conveyance, and air handlers.

• Management of the trades involved in the actual construction.

• Tying the new Data Center together with the old one to allow users remote access to the resources during the migration period.

• Modification of the applications to reflect changes to the logical structure of the new machine, the I/O channel structure, and DASD volume sizes.

• Management of test weekends, running parallel jobs on the two systems to assure all applications were running properly before cutover.

• Building a backout plan, if the cutover failed during the start of business on the day after cutover.

The entire effort was completed in 11 months, ahead of schedule.  Cutover to the new system was accomplished without any issues.
