- This is the first formal fact sheet I have received on the new '486 box. I
- saw it in Atlanta, it was very impressive.
-
- The AT&T StarServer E
-
- PRODUCT DESCRIPTION
-
- The AT&T StarServer E is a powerful, high-performing EISA- based computer
- system which features true symmetric multiprocessing (SMP) scalability.
- Based on the Intel* i486 chip running at 33MHz, the StarServer E can be
- expanded "in- cabinet", from a one CPU (26.5 MIPS) uniprocessor to a four CPU
- (106 MIPS) symmetric multiprocessor system with outstanding performance.
-
- The StarServer E supports symmetric multiprocessing by integrating the Intel
- i486 chip, EISA and a fully symmetric shared-memory implementation of UNIX
- System V Release 4.0 in a uniquely architected AT&T Bell Laboratories system
- design. StarServer E achieves nearly linear scalable performance -- the
- ability to double or triple processing performance by adding two or three (or
- more) i486/33 CPUs.
-
- Contributing to StarServer E's linear scalable performance are two unique
- AT&T Bell Laboratories features (patents pending), its multiple write-back
- cache design and its high performance system bus.
-
- Each CPU processor board comes with 8KB of internal cache memory with a zero
- wait state. External cache memory can be expanded to 256 KB per processor
- board. These external caches are write-back, meaning the data can be
- modified in a CPU's cache. This implementation increases the systems overall
- performance by reducing the frequency and need to go to main memory. In a
- multiprocessing implementation "bus snooping" of the system bus is required
- to ensure that data integrity is maintained. Without snooping, a second CPU
- searching for a data record that has not been written back to main memory
- could receive inconsistent data.
-
- The core of the StarServer E is its system bus, which offers five slots.
- These system bus slots can be populated with any combination of CPU processor
- boards and memory controllers. This system bus design is actually three buses
- in one, featuring two 64-bit data buses (one even, one odd), tied together by
- a 32-bit address bus. The dual buses provide interleaving when multiple
- memory controllers are utilized. This interleaving feature further reinforces
- StarServer E's high-performance. In fact, this system bus design is capable
- of 267 MByte/second "sustainable" (not peak) data throughput rates, a
- distinctive and industry leading characterization that sets StarServer E
- apart from its competition.
-
- The StarServer E is manufactured by AT&T at its Little Rock facility and is
- orderable in three base configurations. These configurations can be
- customized "at the factory" to meet your individual needs.
-
- StarServer E Applications
-
- "Mission critical" applications, such as reservation systems or on-line
- databases, greatly benefit from StarServer E performance, mass storage
- capabilities, disk mirroring, and system management features.
-
- The features and design of the StarServer E give it the flexibility to work
- as a UNIX standalone or development system, a UNIX multi-user system, a UNIX
- server or as a server/multi-user hybrid system.
-
- As a UNIX development system, StarServer E affords you the first opportunity
- to develop applications using the UNIX SVR 4.0 operating system. The
- StarServer E will support the following languages and utilities: C
- Programming Language Utilities 5/4, Cobol/2, C++ Language System Release 2.1,
- LPI Fortran and ADW Cobol 1.1.
-
- As a UNIX multi-user system, StarServer E can easily support 64 to 160
- concurrent users. Concurrent active users have access to sharing diverse
- applications, peripheral device sharing and also have the benefits of a
- reliable and convenient mail/message system. Mid-size workgroups and large
- departments benefit from this two tier architecture that utilizes the
- StarServer E as a host, since terminal devices may be used.
-
- As a server, the StarServer E can operate in an AT&T networked environment or
- in other vendors' networked environments. When configured with AT&T
- StarGROUP Software LAN Manager Server, this combination represents the future
- now. It gives real meaning to distributed applications and client/server
- computing. AT&T is working with Novell and Banyan to ensure that StarServer
- E can operate as a server in these environments. With StarGROUP Software,
- the StarServer E can operate in an IBM* Token Ring Environment and in a 3COM*
- and Racal*-Interlan Ethernets. It supports industry standard protocols and
- interfaces including: OSI, TCP/IP, X.25 and SNA.
-
- As a server/multi-user hybrid system, the best of both worlds is realized in
- this differentiated configuration. StarServer E functions as both a UNIX
- server and as a UNIX multi-user system. This system capability is unique in
- the industry and is not available with any other network operating system
- other than AT&T StarGROUP Software.
