Mainframe Virtual Tape Storage
Virtual tape capacity also exceeds 20 petabytes (PB) on 30 subsystems in multiple data centers and an under construction electronic vault. Over 100,000 tape cartridges are in use; but displacement is occurring as workload migrates onto virtual tape. This capacity is continually expanding as new and enhanced application development progresses. The mainframe application systems and databases are mission critical and have stringent high-availability (24 hours per day, 7 days per week) service level objectives.
Data replication occurs continuously between the data centers and the electronic vault. Periodic application and storage management processes create point-in-time copies onto de-duplicated virtual tape, which in turn is replicated between the data centers and the electronic vault. The data centers provide a recovery point for their peer location in the event of a disaster.
The objective of this task is to provide mainframe storage engineering support to manage the increasing number of complex interrelated Agency virtual-tape-based mainframe applications across multiple data centers.
This task requires strong experience in mainframe storage-infrastructure design and programming on Online Transaction Processing database management-based systems and the ability to develop complex software to satisfy design objectives. This task also requires the ability to: (1) analyze functional business applications and design specifications for functional activities; (2) develop block diagrams and logic flowcharts; (3) translate detailed designs into computer software; (4) develop and perform test/debug functions; (5) refine computer software to produce the required product; and (6) participate in the documentation of systems, infrastructures, and procedures.
Ensure the mainframe storage infrastructure performs so that the agency mission-critical business applications provide the required services to our customers. Ensure data protection against accidental loss, intentional damage, or negative impacts from a natural disaster
