Cloud Computing 2010 - Case history - Giancarlo Gaggero - DSI Europe s.r.l.

  1. 1. 10/05/10 Forum ValueIT Cloud Computing un anno dopo Milano 1 Luglio 2010 Legacy Mainframe Data In The Cloud By G.Gaggero Data Strategies Int’l Europe, S.r.l. Your Logo Here
  2. 2. 10/05/10 Overview Background Data Strategies has been providing for many years a variety of services aimed at extracting, converting, migrating, and preserving mainframe data stored on magnetic tapes. New Services Leveraging this experience, Data Strategies is now offering “ Data Migration Services for Mainframe Migration ” (DMSfMM) for rapid and cost-effective migration of strategic data from tape-based mainframe environment to the Cloud, using Micro Focus ECS.

  3. 3. 10/05/10 The Stage of Mainframe Modernization <ul><ul><li>Many vendors offer Mainframe Modernization tools and services to “move” mainframe applications off the mainframe platform. </li></ul></ul><ul><ul><li>Often these projects involve large amount of legacy mainframe data on tape or other media. </li></ul></ul><ul><ul><li>Generally the modernization vendors migrate only the ‘active data’ (database, VSAM, etc.). </li></ul></ul><ul><ul><li>The challenge of migrating large amounts (hundreds of Terabytes?) of unstructured tape-based legacy data has been only recently recognized. </li></ul></ul><ul><ul><li>Data Strategies has developed a strategy (with associated tools and services) to address this challenge. </li></ul></ul>Your Logo Here
  4. 4. 10/05/10 Strategy Features and … Analysis of Legacy Environment Data Strategies quantifies and qualifies the data to be migrated based on type, source, retention and security requirements using the metadata contained in OS Catalog, TMS, and other control data sources. Transfer of Control Metadata All TMS, OS Catalog, and application specific metadata is “consolidated and moved” to the Migration Database. Virtualization of Tape Data Tape data is migrated in the form of virtual tapes to the Cloud . Bulk data loading is used to minimize the time needed and the cost. Your Logo Here
  5. 5. 10/05/10 … Benefits Analysis of Legacy Environment Almost every time the result of the analysis allows cutting down the amount of data to be migrated significantly (50% or more). Transfer of Control Metadata The control metadata extracted from the mainframe environment and stored inside the Migration Database permit the automatic access and management of the migrated data. Virtualization of Tape Data Virtualization allows maximum flexibility in the way migrated data is “conserved” and accessed. Effectively, it makes possible to “place” the data in the Cloud.
