System Features
Table 1–1 System Characteristics
Characteristic Description
Four–processor capability System can be configured as a uniprocessor or with up
to four 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 for low-cost,
high-capacity flexible configurations
3.5-in. storage devices Up to 16, 3.5-in. high performance disk drives may be
configured in the BA740 pedestal enclosure, providing
many independent disks that may be configured in
stripe sets, shadow sets, or RAID sets to optimize
performance according to customer requirements.
High availability With the optional RAID controller, the system supports
disk hot swap in StorageWorks shelves with the
operating systems as well as clustering.
Optional dual power supply provides N+1 redundancy.
All models except model 4/200 support CPU failover.
CPU chip technology The Alpha chip is manufactured using Digital’s state-
of-the-art CMOS process.
CPU chip design features Superscalar, superpipelined.
System bus bandwidth 667 MB/sec (128-bit, 24-ns cycle.)
Memory Up to two gigabytes of main memory will be supported.
Architecture Figure 1–1 illustrates the server system architecture.
