Where the Data Resides

Centralizing an organization’s data is fundamental to maximizing the benefits a business can derive from it. The mainframe is known as the workhorse for operational transactions because of its inherent availability, security and scalability attributes. Four of the key reasons customers are re-evaluating collocating their data warehouse and operational business-intelligence (BI) systems on System z* servers include:

  1. Minimizing data movement and delay while improving control and availability for critical business information: As applications share the same platform, they can use Hipersocket* connectivity between LPARs, providing a high-speed, memory-to-memory interconnect to ensure data is available, while avoiding constraints that network connectivity imposes.
  2. Supporting next-generation operational BI systems: A key concern when building service-oriented architectures is availability and security. The decision system can’t become the weak link in the operational environment; it needs the same operational attributes as the transaction-production system.
  3. Decreasing data-transfer times: IBM’s System z10* server can transfer data between processor books (banks of processors contained in a “book” module) at a rate of 6 GBs per second. This is 15-times faster than the data transfer of a typical, distributed-commodity server environment.
  4. Eliminating system overhead: Collocation simplifies the environment and removes the overhead associated with issuing remote procedure calls and the overhead associated with encryption since there’s no external network traffic.
