Sun Fire

Sun Fire is a series of server computers introduced in 2001 by Sun Microsystems (since 2010, part of Oracle Corporation). The Sun Fire branding coincided with the introduction of the UltraSPARC III processor, superseding the UltraSPARC II-based Sun Enterprise series. In 2003, Sun broadened the Sun Fire brand, introducing Sun Fire servers using the Intel Xeon processor. In 2004, these early Intel Xeon models were superseded by models powered by AMD Opteron processors. Also in 2004, Sun introduced Sun Fire servers powered by the UltraSPARC IV dual-core processor. In 2007, Sun again introduced Intel Xeon Sun Fire servers, while continuing to offer the AMD Opteron versions as well.

SPARC-based Sun Fire systems were produced until 2010, while x86-64 based machines were marketed until mid-2012. In mid-2012, Oracle Corporation ceased to use the Sun Fire brand for new server models. [1][2]

Operating systems

UltraSPARC-based Sun Fire models are licensed to run the Solaris operating system versions 8, 9, and 10. Although not officially supported, some Linux versions are also available from third parties, as well as OpenBSD and NetBSD.

Intel Xeon and AMD Opteron based Sun Fire servers support Solaris 9 and 10, OpenBSD, Red Hat Enterprise Linux versions 3 - 6, SUSE Linux Enterprise Server 10 and 11, Windows 2000, Windows Server 2003, 2008, and 2008 R2 .

Model nomenclature

Later Sun Fire model numbers have prefixes indicating the type of system, thus:

  • V: entry level and mid-range rackmount and cabinet servers (UltraSPARC, IA-32 or AMD64)
  • E: high-end enterprise class cabinet servers with high-availability features (UltraSPARC)
  • B: blade servers (UltraSPARC or IA-32)
  • X: rackmount x86-64 based servers
  • T: entry level and mid-range rackmount servers based on UltraSPARC T-series CoolThreads processors

When Sun offered Intel Xeon and AMD Opteron Sun Fire servers under the V-Series sub brand, Sun used an x suffix to denote Intel Xeon processor based systems and a z suffix for AMD Opteron processor based systems, but this convention was later dropped. The z suffix was also used previously to differentiate the V880z Visualization Server variant of the V880 server.

Sun's first-generation blade server platform, the Sun Fire B1600 chassis and associated blade servers, was branded under the Sun Fire server brand. Later Sun blade systems were sold under the Sun Blade brand.

In 2007, Sun, Fujitsu and Fujitsu Siemens introduced the common SPARC Enterprise brand for server products. The first SPARC Enterprise models were the Fujitsu-developed successors to the midrange and high-end Sun Fire E-series. In addition, the Sun Fire T1000 and T2000 servers were rebranded as the SPARC Enterprise T1000 and T2000 and sold under the Fujitsu brands, although Sun continued to offer these with their original names. Later T-series servers have also been badged SPARC Enterprise rather than Sun Fire.

Since late 2010, Oracle Corporation no longer uses Sun Fire brand for their current T series SPARC servers, and since mid-2012 for new X series x86-64 machines based on Intel Xeon CPUs. x86-64 server models which had been developed by Sun Microsystems before its acquisition, and were still in production, have all been rebranded as Sun Server X-series.

Sun Fire model range

Some servers were produced in two versions, the original version and a later RoHS version. Since a general maintenance and upgrade guideline is that RoHS components and spares may be installed into the original non-RoHS versions of that server, the end-of-life (EOL) date of a server is deemed the EOL date of the RoHS version of that server in this listing.

Fatima Jibrell (Somali: Fadumo Jibriil; Arabic: فاطمة جبريل‎; born December 30, 1947) is a Somali-American environmental activist. She was the co-founder and Executive Director of the Horn of Africa Relief and Development Organization (now Adeso), co-founder of Sun Fire Cooking, and was instrumental in the creation of the Women's Coalition for Peace.


Fireplane is a computer internal interconnect created by Sun Microsystems.

The Fireplane interconnect architecture is an evolutionary development of Sun's previous Ultra Port Architecture (UPA). It was introduced in October 2000 as the processor I/O interconnect in the Sun Blade 1000 workstation, followed in early 2001 by its use in the Sun Fire and Sun Fire 15K series enterprise servers. These coincided with the popular expansion of the web in the dot com boom and a shift of Sun's main market from Unix workstations to datacenter servers such as the Starfire, supporting high traffic web sites.

Peak performance (in the Sun Blade 1000) reached 67.2 GBytes/second or a sustained 9.6 Gbit/s (2.4 Gbit/s for each processor).Each generation of Sun architecture had involved upgraded processors and matching upgrades to the bus or interconnect architectures that supported them. By this time, fast access to memory was becoming more important than simple CPU instruction speed for overall performance. Multiprocessors, shared memory, memory caching and switching between CPU and memory were technologies necessary to achieve this.

The Sun Fire 15K series frame allows 18 combined processor and memory expander boards. Each board comprises four processors, four memory modules and I/O processors. The Fireplane interconnect uses 18×18 crossbar switches to connect between them. Overall peak bandwidth through the interconnect is 43 Gbytes per second.

As memory architectures increase in complexity, maintaining cache coherence becomes a greater problem than simple connectivity. Fireplane represents a substantial advance over previous interconnects in this aspect. It combines both snoopy cache and point-to-point directory-based models to give a two-level cache coherence model. Snoopy buses are used primarily for single buses with small numbers of processors; directory models are used for larger numbers of processors. Fireplane combines both, to give a scalable shared memory architecture.

Each expander board implements snooping across the board, with directory coherence across the interconnect. Each board is considered as a 'snooping coherence domain'. Small to mid-sized Fireplane systems, up to 24 processors, use a single coherence domain. Larger systems with more processors use multiple coherence domains across their backplane interconnect. Competing systems from makers such as SGI or the HP Superdome series use only a single level of coherency support and so require the more complex directory coherence to be used throughout.

Fireplane used for smaller servers and workstations is optimised for their single domain performance. They use an increased system clock by 50% to 150 MHz. Snoops per clock cycle are also doubled from one half to one. Together these allow a snooping bandwidth of 150 million addresses per second.

Oracle Linux

Oracle Linux (OL, formerly known as Oracle Enterprise Linux) is a Linux distribution packaged and freely distributed by Oracle, available partially under the GNU General Public License since late 2006. It is compiled from Red Hat Enterprise Linux (RHEL) source code, replacing Red Hat branding with Oracle's. It is also used by Oracle Cloud and Oracle Engineered Systems such as Oracle Exadata and others.

Potential users can freely download Oracle Linux through Oracle's E-delivery service (Oracle Software Delivery Cloud) or from a variety of mirror sites, and can deploy and distribute it without cost. The company's Oracle Linux Support program aims to provide commercial technical support, covering Oracle Linux and existing RHEL or CentOS installations but without any certification from the former (i.e. without re-installation or re-boot). As of 2016 Oracle Linux had over 15,000 customers subscribed to the support program.

RSA Insurance Group

RSA Insurance Group plc (trading as RSA, formerly Royal and Sun Alliance) is a British multinational general insurance company headquartered in London, United Kingdom. RSA has major operations in the UK & Ireland, Scandinavia and Canada and provides insurance products and services in more than 140 countries through a network of local partners. It has 9 million customers. RSA was formed by the merger of Sun Alliance and Royal Insurance in 1996.

RSA is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index.


SPARC (Scalable Processor Architecture) is a reduced instruction set computing (RISC) instruction set architecture (ISA) originally developed by Sun Microsystems. Its design was strongly influenced by the experimental Berkeley RISC system developed in the early 1980s. First released in 1987, SPARC was one of the most successful early commercial RISC systems, and its success led to the introduction of similar RISC designs from a number of vendors through the 1980s and 90s.

The first implementation of the original 32-bit architecture (SPARC V7) was used in Sun's Sun-4 workstation and server systems, replacing their earlier Sun-3 systems based on the Motorola 68000 series of processors. SPARC V8 added a number of improvements that were part of the SuperSPARC series of processors released in 1992. SPARC V9, released in 1993, introduced a 64-bit architecture and was first released in Sun's UltraSPARC processors in 1995. Later, SPARC processors were used in symmetric multiprocessing (SMP) and non-uniform memory access (CC-NUMA) servers produced by Sun, Solbourne and Fujitsu, among others.

The design was turned over to the SPARC International trade group in 1989, and since then its architecture has been developed by its members. SPARC International is also responsible for licensing and promoting the SPARC architecture, managing SPARC trademarks (including SPARC, which it owns), and providing conformance testing. SPARC International was intended to grow the SPARC architecture to create a larger ecosystem; SPARC has been licensed to several manufacturers, including Atmel, Bipolar Integrated Technology, Cypress Semiconductor, Fujitsu, Matsushita and Texas Instruments. Due to SPARC International, SPARC is fully open, non-proprietary and royalty-free.

As of September 2017, the latest commercial high-end SPARC processors are Fujitsu's SPARC64 XII (introduced in 2017 for its SPARC M12 server) and SPARC64 XIfx (introduced in 2015 for its PRIMEHPC FX100 supercomputer); and Oracle's SPARC M8 introduced in September 2017 for its high-end servers.

On Friday, September 1, 2017, after a round of layoffs that started in Oracle Labs in November 2016, Oracle terminated SPARC design after the completion of the M8. Much of the processor core development group in Austin, Texas, was dismissed, as were the teams in Santa Clara, California, and Burlington, Massachusetts. SPARC development continues with Fujitsu returning to the role of leading provider of SPARC servers, with a new CPU due in the 2020 time frame.

SPARC Enterprise

The SPARC Enterprise series is a range of UNIX server computers based on the SPARC V9 architecture. It was co-developed by Sun Microsystems and Fujitsu, and introduced in 2007. They were marketed and sold by Sun Microsystems (later Oracle Corporation, after their acquisition of Sun), Fujitsu, and Fujitsu Siemens Computers under the common brand of "SPARC Enterprise", superseding Sun's Sun Fire and Fujitsu's PRIMEPOWER server product lines.

Since 2010, servers based on new SPARC CMT processors (SPARC T3 and later) have been branded as Oracle's SPARC T-Series servers.

SPARC T series

The SPARC T-series family of RISC processors and server computers, based on the SPARC V9 architecture, was originally developed by Sun Microsystems, and later by Oracle Corporation after its acquisition of Sun. Its distinguishing feature from earlier SPARC iterations is the introduction of chip multithreading (CMT) technology, a multithreading, multicore design intended to drive greater processor utilization at lower power consumption.

The first generation T-series processor, the UltraSPARC T1, and servers based on it, were announced in December 2005. As later generations were introduced, the term "T series" was used to refer to the entire family of processors.

Sun Constellation System

Sun Constellation System is an open petascale computing environment introduced by Sun Microsystems in 2007.

Sun Enterprise

Sun Enterprise is a range of UNIX server computers produced by Sun Microsystems from 1996 to 2001. The line was launched as the Sun Ultra Enterprise series; the Ultra prefix was dropped around 1998. These systems are based on the 64-bit UltraSPARC microprocessor architecture and related to the contemporary Ultra series of computer workstations. Like the Ultra series, they run Solaris. Various models, from single-processor entry-level servers to large high-end multiprocessor servers were produced. The Enterprise brand was phased out in favor of the Sun Fire model line from 2001 onwards.

Sun Fire 15K

The Sun Fire 15K (codenamed Starcat) was an enterprise-class server computer from Sun Microsystems based on the SPARC V9 processor architecture. It was announced on September 25, 2001 in New York City, superseding the Sun Enterprise 10000. General availability was in January 2002; the last to be shipped was in May 2005.

The Sun Fire 15K supported up to 106 UltraSPARC III processors (up to 1.2 GHz), or 72 UltraSPARC IVs (up to 1.35 GHz) installed across 18 system boards (Uniboards, containing CPU sockets and RAM slots). With the UltraSPARC III, Sun supported up to 17 dual-socket "MaxCPU" processor cards in place of I/O mezzanine cards, a configuration not supported with UltraSPARC IV. Maximum physical RAM per system is 576 GB. A maximum of 72 PCI I/O slots are available.

The system can be divided into a maximum of 18 secure independent domains, each of which is a separate machine with its own filesystems, root password and the ability to run different versions of Solaris. The E15k, along with other enterprise Sun servers, has the Dynamic Reconfiguration feature: administrators could dynamically change the assignment of RAM and processors to the different domains to meet changes in business needs. In addition, the 15K contains two system controllers (duplicated for redundancy), which are embedded SPARC computers running Solaris and used to manage the 15K and perform tasks such as booting and shutting down domains and assigning Uniboards to domains. The 15K contains minimal storage in itself (only system controller boot disks); it is connected via SAN to a separate storage array.

Sun Fire T2000

The Sun Fire T2000 server (code named Ontario) is a system engineered by Sun Microsystems for applications including Web 2.0 and databasing. Part of the Sun Fire line, the T2000 was among the first servers to leverage Sun's CoolThreads processing technology, which improves the energy-efficiency of systems.

Introduced in December 2005, the Sun T2000 reached its end of life (EOL) in November 2009.

Sun Fire X4500

The Sun Fire X4500 data server (code named Thumper) integrates server and storage technologies. It was announced in July, 2006 and is part of the Sun Fire server line from Sun Microsystems.

In July 2008, Sun announced the X4540 model (code-named Thor), which doubles the processing power of the X4500.

In November 2010, Oracle designated that the X4540 is end-of-life and has no next-generation replacement model.

Sun Microsystems

Sun Microsystems, Inc. was an American company that sold computers, computer components, software, and information technology services and created the Java programming language, the Solaris operating system, ZFS, the Network File System (NFS), and SPARC. Sun contributed significantly to the evolution of several key computing technologies, among them Unix, RISC processors, thin client computing, and virtualized computing. Sun was founded on February 24, 1982. At its height, the Sun headquarters were in Santa Clara, California (part of Silicon Valley), on the former west campus of the Agnews Developmental Center.

On April 20, 2009, it was announced that Oracle Corporation would acquire Sun for US$7.4 billion. The deal was completed on January 27, 2010.Sun products included computer servers and workstations built on its own RISC-based SPARC processor architecture, as well as on x86-based AMD Opteron and Intel Xeon processors. Sun also developed its own storage systems and a suite of software products, including the Solaris operating system, developer tools, Web infrastructure software, and identity management applications. Other technologies included the Java platform and NFS. In general, Sun was a proponent of open systems, particularly Unix. It was also a major contributor to open-source software, as evidenced by its $1 billion purchase, in 2008, of MySQL, an open-source relational database management system. At various times, Sun had manufacturing facilities in several locations worldwide, including Newark, California; Hillsboro, Oregon; and Linlithgow, Scotland. However, by the time the company was acquired by Oracle, it had outsourced most manufacturing responsibilities.


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.


The UltraSPARC IV Jaguar and follow-up UltraSPARC IV+ Panther are microprocessors designed by Sun Microsystems and manufactured by Texas Instruments. They are the fourth generation of UltraSPARC microprocessors, and implement the 64-bit SPARC V9 instruction set architecture (ISA). The UltraSPARC IV was originally to be succeeded by the UltraSPARC V Millennium, which was canceled after the announcement of the Niagara, now UltraSPARC T1 microprocessor in early 2004. It was instead succeeded by the Fujitsu-designed SPARC64 VI.

The UltraSPARC IV was developed as part of Sun's Throughput Computing initiative, which included the UltraSPARC V Millennium, Gemini and UltraSPARC T1 Niagara microprocessors. Of the four original designs in the initiative, two reached production: the UltraSPARC IV and the UltraSPARC T1. Whereas the Millennium and Niagara implemented block multithreading - also known as coarse-grained multithreading, the UltraSPARC IV implemented chip-multithreading (CMP) — multiple single-thread cores.

The UltraSPARC IV was the first multi-core SPARC processor, released in March, 2004. Internally, it implements two modified UltraSPARC III cores, and its physical packaging is identical to the UltraSPARC III with the exception of one pin. The UltraSPARC III cores were improved in a variety of ways. Instruction fetch, store bandwidth, and data prefetching were optimized. The floating-point adder implements additional hardware to handle more not a number (NaN) and underflow cases to avoid exceptions. Both cores share a L2 cache with a capacity of up to 16 MB but have their own L2 cache tags.

The UltraSPARC IV contains 66 million transistors and measures 22.1 mm by 16.1 mm (356 mm2). It was fabricated by Texas Instruments in their 0.13 µm process.

The UltraSPARC IV+, released in mid-2005, is also a dual-core design, featuring enhanced processor cores and an on-chip L2 cache. It is fabricated on a 90 nanometer manufacturing process. The initial speed of the UltraSPARC IV+ was 1.5 GHz, 0.3 GHz less than the intended 1.8 GHz. In April, 2007 it was increased to 2.1 GHz. It contains 295 million transistors.Servers using the UltraSPARC IV were released in September 2004. The UltraSPARC IV+ was released in Sun servers in September 2005. Sun Fire V490, V890, E2900, E4900, E6900, E20K and E25K systems all use UltraSPARC IV and IV+ processors. These systems range from 4 to 72 processor sockets (8 to 144 cores).

Servers powered by the UltraSPARC IV+ processor were well received, allowing Sun to regain revenue lead in the RISC/UNIX server market in 2006.


Sun Microsystems' UltraSPARC T1 microprocessor, known until its 14 November 2005 announcement by its development codename "Niagara", is a multithreading, multicore CPU. Designed to lower the energy consumption of server computers, the CPU typically uses 72 W of power at 1.4 GHz.

Afara Websystems pioneered a radical thread-heavy SPARC design. The company was purchased by Sun, and the intellectual property became the foundation of the CoolThreads line of processors, starting with the T1. The T1 is a new-from-the-ground-up SPARC microprocessor implementation that conforms to the UltraSPARC Architecture 2005 specification and executes the full SPARC V9 instruction set. Sun has produced two previous multicore processors (UltraSPARC IV and IV+), but UltraSPARC T1 is its first microprocessor that is both multicore and multithreaded. Security was built-in from the very first release on silicon, with hardware cryptographic units in the T1, unlike contemporary general purpose processor from competing vendors. The processor is available with four, six or eight CPU cores, each core able to handle four threads concurrently. Thus the processor is capable of processing up to 32 threads concurrently.

UltraSPARC T1 can be partitioned in a similar way to high-end Sun SMP systems. Thus, several cores can be partitioned for running a single or group of processes and/or threads, while the other cores deal with the rest of the processes on the system.


Sun Microsystems' UltraSPARC T2 microprocessor is a multithreading, multi-core CPU. It is a member of the SPARC family, and the successor to the UltraSPARC T1. The chip is sometimes referred to by its codename, Niagara 2. Sun started selling servers with the T2 processor in October 2007.
