Currently this server is a Multiprise 3000, which can connect through ESCON channels only. This will exclude this approach to migrate data to the DS6000, which only provides a pure FICON or Fibre Channel connectivity. It can be used, though, for the DS8000, which still allows you to connect to the ESCON infrastructure through supported ESCON host adapters. IBM plans to enhance the Piper server with FICON channel capable hardware to allow migration to FICON-only environments. Currently the IBM Piper migration service offering includes the following, which IBM provides:

￿S/390 Multiprise 3000

￿An ESCON director with 16 ports to connect to the customer z/Series-based fabric

￿Preloaded FDRPAS migration software

￿19 inch rack enclosure

￿Agent tasks which need to be installed in the customer systems

An FDRPAS master task runs on the Piper CPU, which coordinates all activities. Monitor tasks are required on the customer’s systems to monitor and coordinate with the swap task in the Piper CPU.

The advantages of this Piper-based migration offering are:

￿Simple installation without the need for IPLs on the customer side.

￿Transparent data migration without interruption to connected application hosts and no application down time.

￿Parameter-controlled activity which can be dynamically modified at any time to pace the migration.

￿Suspend/resume of migration at any time without exposing data integrity.

￿Migration during usual business hours for convenient management of the migration process.

￿Independent of hardware vendor and suited for all S/390 or zSeries attached disk storage.

￿Supports Parallel Access Volume handling.
