Commercial performance in 1-, 2-, 4-, or 6-way enterprise servers using the
RS64 III microprocessor technology.
Reliability, availability, and serviceability (RAS) providing:
– Error checking and correcting (ECC) system memory and cache
– I/O link failure recovery
– Environmental sensing
– N+1 Power
– N+1 Cooling units
– Service processor for integrated system monitoring
– Concurrent diagnostics
Preconfigured tailored solutions that take advantage of the rack packaging to
custom tailor your solution. Choose from multiple SCSI, SSA, or Fibre
Channel attached:
– Storage
– Media
– Communication
Open industry standards, such as Open Firmware based on IEEE P1275
standard.
Processor and memory growth. The minimum configuration 1-way processor
can be increased to a 2-way, 4-way, or 6-way SMP. Memory can be
expanded up to 16 GB in 256 MB, 512 MB, or 1 GB increments.
Industry-standard, hot-plug PCI slots allow most PCI adapters to be removed,
added, or replaced without powering down the system. This function
enhances system availability and serviceability.
System power supplies are available in AC or DC and are designed to
support up to 6-way SMP systems with 16 GB of memory. An optional
modular AC power supply can be added to provide redundant power for AC
systems. Redundant power is standard on systems with DC power.
Industry recognized AIX operating system license included with each system.
New performance enhancements and Workload Management features are
included with the latest release.
Primary I/O drawer that features:
– Two integrated SCSI controllers (F/W and Ultra2)
– An Ethernet 10/100 controller
– Four serial ports
– One parallel port
