GS21 1400

GS21 1400 The large-scale mainframe system "GS21 1400 model group" is equipped with our new in-house developed quad core processor, on a single-chip.
Performance is improved by up to 30% compared to the previous model.
GS21 1400 model group also has enhanced Green ICT credentials plus outstanding performance and reliability.


GlobalServer "GS21 1400 model group" provides the power to consolidate your business, information, and optimize your IT infrastructure.

With the current challenging business environment, many companies are looking to cut deployment and operating costs by consolidating servers and storage into datacenters. They are also showing increased interest in intra-corporate cloud computing and other IT infrastructure optimization strategies that link multiple systems seamlessly and efficiently using SOA.

In addition, such companies are also being viewed by the public, not only for the products and services they provide, but also on their business continuity, stability, legal compliance, and environmental actions.
In this climate, and as a result of the mainframe server’s crucial role in centralized data processing, its importance is being re-acknowledged.
GlobalServer, with its enhanced performance and reliability, coupled with green IT credentials is able to contribute to customer business growth and improved customer value.

Improved processing performance

  • New processors are integrated quad-core CPU chips.
    A 30 percent performance increase is achieved, compared with the previous GR21 500 model, by the integration of 4 CPU with 128KB first level cache and 5MB second level cache onto a single chip LSI.
  • XAUI technology is used for the interface between cluster and SSU.
    Achieves a max 10% increase in data transfer speed compared to GS21 500.

Improved business continuity

  • Enhanced RAS features on the interface between cluster and SSU
    ensures operation of both SSU in dual configuration if an interface failure should occur.

Green ICT approach

  • Max 15% power consumption reductions, compared to GS 21 500, by use of new high density processora with multi-core technology.
  • Environmentally friendly approach
    Volatile organic compounds have been completely removed from all housing paintwork by use of a new powder coating which does not require solvent.
