Sun4us
Sun-4 is a series of Unix workstations and servers produced by Sun Microsystems, launched in 1987. The original Sun-4 series were VMEbus-based systems similar to the earlier Sun-3 series, but employing microprocessors based on Sun's own SPARC V7 RISC architecture in place of the 68k family processors of previous Sun models. Sun 4/280 was known as base system that was used for building of first RAID prototype. Models Models are listed in approximately chronological order. : In 1989, Sun dropped the "Sun-4" name for marketing purposes in favor of the SPARCstation and SPARCserver brands for new models, although early SPARCstation/server models were also assigned Sun-4-series model numbers. For example, the SPARCstation 1 was also known as the Sun 4/60. This practice was phased out with the introduction of the SPARCserver 600MP series in 1991. The term ''Sun-4'' continued to be used in an engineering context to identify the basic hardware architecture of all SPARC-based Sun system ...

Unix
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley (Berkeley Software Distribution, BSD), Microsoft (Xenix), Sun Microsystems (SunOS/Solaris (operating system), Solaris), Hewlett-Packard, HP/Hewlett Packard Enterprise, HPE (HP-UX), and IBM (IBM AIX, AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold the UNIX trademark to The Open Group, an industry consortium founded in 1996. The Open Group allows the use of the mark for certified operating systems that comply with the Single UNIX Specification (SUS). Unix systems are chara ...

SunOS
SunOS is a Unix-branded operating system developed by Sun Microsystems for their workstation and server computer systems. The ''SunOS'' name is usually only used to refer to versions 1.0 to 4.1.4, which were based on BSD, while versions 5.0 and later are based on UNIX System V Release 4, and are marketed under the brand name ''Solaris''. History SunOS 1 only supported the Sun-2 series systems, including Sun-1 systems upgraded with Sun-2 (68010) CPU boards. SunOS 2 supported Sun-2 and Sun-3 (68020) series systems. SunOS 4 supported Sun-2 (until release 4.0.3), Sun-3 (until 4.1.1), Sun386i (4.0, 4.0.1 and 4.0.2 only) and Sun-4 (SPARC) architectures. Although SunOS 4 was intended to be the first release to fully support Sun's new SPARC processor, there was also a SunOS 3.2 release with preliminary support for Sun-4 systems. SunOS 4.1.2 introduced support for Sun's first sun4m-architecture multiprocessor machines (the SPARCserver 600MP series); since it ...

Sun Ultra Series
The Sun Ultra series is a discontinued line of workstation and server computers developed and sold by Sun Microsystems, comprising two distinct generations. The original line was introduced in 1995 and discontinued in 2001. This generation was partially replaced by the Sun Blade in 2000 and that line was in itself replaced by the Sun Java Workstation—an AMD Opteron system—in 2004. In sync with the transition to x86-64-architecture processors, in 2005 the Ultra brand was later revived with the launch of the Ultra 20 and Ultra 40, albeit to some confusion, since they were no longer based on UltraSPARC processors. History Original model The original Ultra workstations and the Ultra Enterprise (later, "Sun Enterprise") servers were UltraSPARC-based systems produced from 1995 to 2001, replacing the earlier SPARCstation and SPARCcenter/SPARCserver series respectively. This introduced the 64-bit UltraSPARC processor and in later versions, lower-cost PC-derived tech ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
64-bit
In computer architecture, 64-bit Integer (computer science), integers, memory addresses, or other Data (computing), data units are those that are 64 bits wide. Also, 64-bit central processing unit, CPUs and arithmetic logic unit, ALUs are those that are based on processor registers, address buses, or Bus (computing), data buses of that size. A computer that uses such a processor is a 64-bit computer. From the software perspective, 64-bit computing means the use of machine code with 64-bit virtual memory addresses. However, not all 64-bit instruction sets support full 64-bit virtual memory addresses; x86-64 and ARMv8, for example, support only 48 bits of virtual address, with the remaining 16 bits of the virtual address required to be all 0's or all 1's, and several 64-bit instruction sets support fewer than 64 bits of physical memory address. The term ''64-bit'' also describes a generation of computers in which 64-bit processors are the norm. 64 bits is a Word (computer archit ...

UltraSPARC
The UltraSPARC is a microprocessor developed by Sun Microsystems and fabricated by Texas Instruments, introduced in mid-1995. It is the first microprocessor from Sun to implement the 64-bit SPARC V9 instruction set architecture (ISA). Marc Tremblay was a co-microarchitect. Microarchitecture The UltraSPARC is a four-issue superscalar microprocessor that executes instructions in in-order. It has a nine-stage integer pipeline. Functional units The execution units were simplified relative to the SuperSPARC to achieve higher clock frequencies - an example of a simplification is that the ALUs were not cascaded, unlike the SuperSPARC, to avoid restricting clock frequency. The integer register file has 32 64-bit entries. As the SPARC ISA uses register windows, of which the UltraSPARC has eight, the actual number of registers is 144. The register file has seven read and three write ports. The integer register file provides registers to two arithmetic logic units and the load/store ...

Cray CS6400
The Cray Superserver 6400, or CS6400, is a discontinued multiprocessor server computer system produced by Cray Research Superservers, Inc., a subsidiary of Cray Research, and launched in 1993. The CS6400 was also sold as the Amdahl SPARCsummit 6400E. The CS6400 (codenamed ''SuperDragon'' during development) superseded the earlier SPARC-based Cray S-MP system, which was designed by Floating Point Systems. However, the CS6400 adopted the XDBus packet-switched inter-processor bus also used in Sun Microsystems' SPARCcenter 2000 (''Dragon'') and SPARCserver 1000 (''Baby Dragon'' or ''Scorpion'') Sun4d systems. This bus originated in the Xerox Dragon multiprocessor workstation designed at Xerox PARC. The CS6400 was available with either 60 MHz SuperSPARC-I or 85 MHz SuperSPARC-II processors, maximum RAM capacity was 16 GB. Other features shared with the Sun servers included use of the same SuperSPARC microprocessor and Solaris operating system. However, the CS6400 could ...

Sun4d
Sun4d is a computer architecture introduced by Sun Microsystems in 1992. It is a development of the earlier Sun-4 architecture, using the XDBus system bus, SuperSPARC processors, and SBus I/O cards. The XDBus was the result of a collaboration between Sun and Xerox; its name comes from an earlier Xerox project, the Xerox Dragon. These were Sun's largest machines to date, and their first attempt at making a mainframe-class server. Architecture Sun4d computers are true SMP systems; although memory and CPUs are installed per system board, the memory on a given board is not in any way " closer" to the CPUs on that same board. All memory and I/O devices are equally connected to all CPUs. All of these computers use a passive backplane into which system boards are plugged. Each system board provides CPUs, memory, and an I/O bus. As system boards are added, these components are added to the whole in a completely seamless fashion. It is not a cluster, but works as a single large machin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPARCstation 5
SPARCstation 5 or SS5 (code-named ''Aurora'') is a workstation introduced by Sun Microsystems in March 1994. It is based on the sun4m architecture, and is enclosed in a pizza box form factor, pizza-box chassis. Sun also offered a SPARCserver 5 without a framebuffer. A simplified, cheaper version of the SS5 was released in February 1995 as the SPARCstation 4. Sun also marketed these same machines under the "Netra" brand, without framebuffers or keyboards and preconfigured with all the requisite software to be used as web servers. An estimated 400,000+ SPARCstation 5s were sold. Specifications Release Price Sun rolled out the SPARCstation 5 for . CPU support The SPARCstation 5 may incorporate one of the following processors: 70, 85, or 110 MHz Sun Microsystems microSPARC-II, or a 170 MHz Fujitsu Microelectronics, Inc. (FMI) TurboSPARC. Fujitsu also provided a 160 MHz TurboSPARC CPU Upgrade Kit for upgrading 70, 85 and 110 MHz microSPARC-II models. The SPARCstati ...

MBus (SPARC)
MBus is a computer bus designed and implemented by Sun Microsystems for communication between high speed computer system components, such as the central processing unit, motherboard and main memory. SBus is used in the same machines to connect add-on cards to the motherboard. MBus was first used in Sun's first multiprocessor SPARC-based system, the SPARCserver 600MP series (launched in 1991), and later found use in the SPARCstation 10 and SPARCstation 20 workstations. The bus permits the integration of several microprocessors on a single motherboard, in a multiprocessing configuration with up to eight CPUs packaged in detachable MBus modules. In practice, the number of processors per MBus is limited to four. Single processor systems were also sold that use the MBus protocol internally, but with the CPUs permanently attached to the motherboard to lower manufacturing costs. MBus specifies a 64-bit datapath, which uses 36-bit physical addressing, giving an address space of 64 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiprocessor
Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. The term also refers to the ability of a system to support more than one processor or the ability to allocate tasks between them. There are many variations on this basic theme, and the definition of multiprocessing can vary with context, mostly as a function of how CPUs are defined ( multiple cores on one die, multiple dies in one package, multiple packages in one system unit, etc.). According to some on-line dictionaries, a multiprocessor is a computer system having two or more processing units (multiple processors) each sharing main memory and peripherals, in order to simultaneously process programs. A 2009 textbook defined multiprocessor system similarly, but noting that the processors may share "some or all of the system’s memory and I/O facilities"; it also gave tightly coupled system as a synonymous term. At the operating system level, ''multiprocessing'' is som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SBus
SBus is a computer bus system that was used in most SPARC-based computers (including all SPARCstations) from Sun Microsystems and others during the 1990s. It was introduced by Sun in 1989 to be a high-speed bus counterpart to their high-speed SPARC processors, replacing the earlier (and by this time, outdated) VMEbus used in their Motorola 68020- and 68030-based systems and early SPARC boxes. When Sun moved to open the SPARC definition in the early 1990s, SBus was likewise standardized and became IEEE-1496. In 1997 Sun started to migrate away from SBus to the Peripheral Component Interconnect (PCI) bus, and today SBus is no longer used. The industry's first third-party SBus cards were announced in 1989 by Antares Microsystems; these were a 10BASE2 Ethernet controller, a SCSI-SNS host adapter, a parallel port, and an 8-channel serial controller. The specification was published by Edward H. Frank and James D. Lyle. A technical guide to the bus was published in 1992 in book form b ...
