GS21 400

Leading Broadband information systems

As with all GS servers the design requirements of Enterprise Information systems based on broadband Internet must include:

GS21 400
  1. Capability to handle ever increasing transaction throughput and high-volumes of information,
  2. Expansion capability that matches sudden changes in data quantity and business volume,
  3. High reliability and the capability to be driven continuously -24/7.

To meet these broadband requirements Fujitsu's GlobalServer GS21 400 model group, uses CMOS technology, to provide high system performance for today's new information systems requirements, in a smaller unit.
As a high-end server it can deliver the highest in reliability from leading parallel technology. As a core of a data center, these powerful systems go beyond improved reliability, to provide operational improvements across the entire system and network.

Leading CMOS server

GS21 400

System Performance at the highest level

Highest possible performance is achieved using the same gigahertz class CMOS processors, with leading 0.13 μm copper technology, as larger GS models. Further enhancements come from high-density packaging, the greater efficiency of on-processor L2 cache memory, and the ability to add up to 32GB of main memory.



Broadband Internet Capability

Both channel and LAN are enabled for gigabit Ethernet Open Network Adaptors(ONA). Support for direct connection based no 1000BASE-/SX/T, ensures an optimum Broadband Internet network environment.



Open Systems Conformance

Open systems (UNIX,Windows) high speed file support and flexible multi-server environment support, ensure highly productive system construction.



High reliability hardware

GlobalServer comes as standard with a wide range of high reliability features:


Hardware Instruction retry

If during command processing a problem occurs, the instruction is automatically re-executed.



Automatic fail-back

Hardware memory functions such as Cache memory and Translation Look-aside Buffers(TLB) have degeneration functions that ensure processing continues even if partial failure occurs.


Automatic assignment of alternate memory

For the maintenance of important instruction data in System Storage and Main memory, spare chips are assigned to enable hard faults to be overcome automatically. In addition, at fixed intervals, a patrol mechanism internally investigates memory to provide pre-failure alerts.


Duplex Power source

Electric power can be supplied from two separate sources. This ensures that if one source fails, for some reason, power supply to the system is maintained.
