- Meiko's Commitment to Open Systems
- ----------------------------------
-
- Open Systems facilitate the entry of new players into the computer market by
- causing a reduction in the barriers to entry. The definition of clearly defined
- and widely published standards provides benefits to both the vendor and user
- communities.
-
- Vendors can take advantage of modularised component subsystems, such as disk
- interfaces, I/O buses, Operating Systems etc, without having to invest in
- producing these items themselves. Newer, smaller players can produce innovative
- computer systems without the R&D overhead that previously confined this work
- solely to the province of large organisations. With the lower level system
- components widely available, the system vendors can concentrate on adding value
- and functionality by integrating these widely available components in
- innovative and more functional ways.
-
- The benefits from the user perspective are equally significant. The establish-
- ment of standards means that applications are portable and users are no longer
- tied to their vendors. Users can now shop around for the provision of the
- underlying hardware platforms and competition between suppliers becomes far
- more intense. Competition brings all the usual benefits in terms of increased
- functionality and decreasing prices. In addition, users can afford to invest in
- more innovative hardware as the risk factor is largely negated by the knowledge
- that should the user wish to migrate to a different vendor, for whatever reason,
- that this is entirely feasible.
-
- To some extent, large companies can ignore or modify standards and still
- compete (eg. DEC's development of ULTRIX, their own unique and incompatible
- version of UNIX). Full standards compliance by these companies is often delayed
- by their own commercial considerations. Many larger suppliers continue to deve-
- lop and market proprietary system architectures. Meiko systems are completely
- Open Systems based and we have no proprietary product lines. In order to be
- competitive, small companies must observe standards religiously and must be as
- standards compliant as possible at all times. This is clearly understood at
- Meiko and is reflected in all of Meiko's products. Meiko's systems are designed
- to use the most widely available and clearly established standards at all
- levels of the architecture.
-
- Meiko's strict adherence to an Open System strategy is most clearly visible in
- the following areas:
-
- * Operating System
- * Microprocessor and Memory Architecture
- * Disk and Peripheral Interfaces
- * Expansion - I/O Bus
- * Networking
-
- Operating System: SunOS: UNIX SVR4
- ----------------------------------
-
- The Operating System used on Meiko systems is the widely available UNIX version
- produced by Sun Microsystems, Solaris 1.0 (formerly known as SunOS 4.1). Meiko
- maintains full binary compatibility with Solaris 1.0 and is therefore able to
- run any application (there are c. 4,000 now available) which runs on a Sun
- SPARC workstation.
-
- Sun is a key collaborator with UNIX System Laboratories, the original prod-
- ucers and publishers of the UNIX Operating System. Sun Microsystems is a
- founder member of UNIX International. Solaris 2.0, the next major release of
- this Operating System is Sun's implementation of the USL's System V Release 4
- (SVR4) and will be subsequently available on Meiko systems.
-
- Microprocessor and Memory Architectures
- ---------------------------------------
-
- Meiko systems use the Sun SPARC microprocessor as the processor engine.
- SPARC is an open microprocessor design now licensed by SPARC International,
- an independent consortium of SPARC system vendors not proprietary to any one
- company. This openness means that development and production
- of is not confined to any single company and there is fierce competition in
- provision of this component. Among the major computer system vendors who have
- adopted SPARC as their strategic microprocessor architecture are Fujitsu,
- Amdahl, Sun, Hyundai and ICL.
-
- Meiko use the MBus memory bus interface developed by Sun. MBus is now also an
- open standard administered by SPARC International. Meiko systems use standard
- SIMM memory technology widely available from numerous sources.
-
- Disk/Peripheral Interfaces
- --------------------------
-
- Meiko systems utilise the industry standard Small Computer Systems Interface
- (SCSI) standard for attachment of disks and peripherals. SCSI is the most
- widely used peripheral attachment mechanism in the industry and is used on
- systems from PCs to mainframes. Manufacturers of SCSI disks include Seagate,
- Fujitsu, CDC, Maxtor, Conner, Siemens, Micropolis, IBM, Hewlett-Packard and
- Hitachi. SCSI is also the most widely available connection mechanism for other
- peripherals. There is a very wide availability of peripherals for this standard
- including optical backup devices (CD-ROM, WORM jukeboxes etc), Digital Audio
- Tape backup devices, 3480 cartridge tape backup devices and other more advanced,
- high capacity backup devices. SCSI support allows Meiko to offer the greatest
- possible flexibility to our customers in terms of peripheral connectivity.
-
- I/O Bus
- -------
-
- Meiko systems support the SBus standard for I/O interconnect.
-
- SBus is widely supported by third party manufacturers providing a very broad
- range of facilities. These include SCSI controller cards, FDDI network cards,
- T1 network cards, Token Ring network cards and multiple serial line controller
- cards. Supporting SBus offers Meiko customers great flexibility to address
- even the most demanding and complex I/O and communications requirements.
-
- Networking
- ----------
-
- The ability to support SBus facilitates the physical connection of Meiko
- systems to the widest possible range of protocols and physical networks. This
- connectivity is augmented by the software capability in running the full range
- of Sun compatible communications software. This includea a wide range of IBM SNA products such as Token Ring, LU 6.2 - APPC and 3270.
