System Features
Table 1–1 System Characteristics
Characteristic Description
Two-processor capability System can be configured with either one or two
processors.
High-performance PCI I/O
subsystem PCI is the emerging industry-standard bus that
supports Digital and third-party options. The current
implementation of PCI on the server has a peak
bandwidth of 132 MB/sec.
EISA I/O bus 33 MB/sec EISA I/O bus supports industry standard
EISA options, such as:
Network adapters
Video/audio options
Storage adapters
Flexible mass storage
strategy StorageWorks compatible storage devices provide
low-cost, high-capacity flexible configurations.
3.5-in. storage devices Up to eight 3.5-in. high-performance disk drives can be
configured in the BA720 pedestal enclosure, providing
many independent disks that can be configured in
stripe sets, shadow sets, or RAID sets to optimize
performance according to customer requirements.
High availability With the optional SWXCR RAID controller, your system
supports disk hot swap in StorageWorks shelves
with all operating systems as well as clustering for
OpenVMS. Optional dual power supply provides N+1
redundancy. Multiprocessor systems support CPU
failover.
CPU chip technology The DECchip 21064 is manufactured using Digital’s
state-of-the-art CMOS process. This process uses a
feature size of 0.75 micron. The chip contains 1.7
million transistors on one die.
CPU clock rate 190 MHz to 300+ MHz with advanced processors.
CPU chip design features Superscalar, superpipelined.
System bus bandwidth 667 MB/sec (128-bit, 24-ns cycle).
Memory Up to 640 megabytes of main memory.
