Sun Fire X4200 servers

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 In 2004, these early Intel Xeon models were superseded by models powered by AMD Opteron processors.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

[edit]

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

[edit]

Sun Fire T2000 (top)

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

[edit]

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.

Sun Fire is a series of enterprise-class server computers introduced by in 2001, initially centered on the SPARC-based UltraSPARC III processor architecture and designed to provide high reliability, scalability, and performance for demanding applications such as workloads running on the Solaris operating system. The inaugural models, unveiled at the trade show in , , on March 23, 2001—following a formal introduction in New York the day prior—included the midrange Sun Fire 3800, 4800, 4810, and 6800 servers, which offered mainframe-like capabilities including full hardware redundancy, redundant storage and network connections, and support for live operating system upgrades without downtime. These systems were engineered for 100% binary compatibility with existing Sun hardware and software, positioning them as top platforms for enterprise while targeting competitors like , , , and HP. Performance highlights included the 12-processor Sun Fire 4800 achieving 60,000 operations per second and the 24-processor Sun Fire 6800 reaching 109,000 operations per second on the SpecJBB benchmark. The Sun Fire lineup subsequently broadened to encompass entry-level rackmount servers, high-end systems like the Sun Fire 15K flagship announced in October 2001—which supported up to 106 UltraSPARC III processors for massive scalability in environments—and later x86-based models such as the Opteron-powered Sun Fire V20z and V40z servers launched in 2004, enabling 32-bit and for high-performance applications, , and cost-effective expansion. Following Corporation's acquisition of , completed on January 27, 2010, for $7.4 billion, the Sun Fire branding persisted on various and x86 servers to support ongoing enterprise deployments before transitioning to 's unified server portfolio.

History

Launch and Early Development

Sun Microsystems introduced the server line in 2001 as a successor to the series, emphasizing platforms built around the UltraSPARC III processor to address enterprise demands for scalable and reliable systems. The branding shift marked a new era for server offerings, focusing on enhanced interconnect technology like the Sun Fireplane, which delivered up to 9.6 GB/s sustained throughput for improved system performance. The initial announcement occurred at the trade show in , , on March 23, 2001, where Sun unveiled details of the midrange Sun Fire servers, positioning them as a direct competitor to IBM's pSeries and HP's Superdome lines in the Unix server market. Key early models included the Sun Fire 6800, a system supporting up to 24 processors, which achieved general availability on April 16, 2001. This launch highlighted Sun's emphasis on architecture advantages, such as superior reliability through features like hot-pluggable components and error-correcting memory, alongside of hardware with the Solaris operating system for optimized performance. In 2000 and 2001, Sun expanded the Sun Fire portfolio to and entry-level segments, with models like the rack-optimized Sun Fire 280R providing enterprise-class availability in a compact form factor for smaller deployments. First shipments of initial models, such as the 3800-6800 series, commenced in May 2001, with the integration of UltraSPARC III Cu variants announced in July 2001 for further performance gains. The servers featured tight Solaris OS integration, starting with Solaris 8 support, which enabled advanced resource management and compatibility with existing applications. A standout scalability innovation was dynamic system domains, allowing hardware partitioning into multiple isolated environments without downtime, a capability that predated similar features in competitors' high-end Unix servers by several years. This early development phase solidified Sun Fire's market positioning against and HP by underscoring SPARC's reliability—evidenced by sustained uptime in mission-critical environments—and Sun's end-to-end control over the hardware-software stack, reducing integration complexities for customers. Through the mid-2000s, these foundations enabled Sun Fire to capture significant share in , with dynamic domains and Solaris synergy driving adoption in sectors requiring fault-tolerant partitioning.

Oracle Acquisition and Phase-Out

In January 2010, Oracle Corporation completed its acquisition of for $7.4 billion in an all-cash transaction, marking a significant shift in the strategic direction of Sun's hardware portfolio, including the Sun Fire server line. This deal, finalized after regulatory approvals from the U.S. Department of Justice and the , integrated Sun's hardware expertise with Oracle's software dominance, emphasizing engineered systems that combined servers, storage, and database technologies for optimized performance. Under Oracle's ownership, the focus pivoted from standalone hardware innovation to tightly integrated solutions, such as Exadata and Exalogic, which bundled Sun Fire-derived components with Oracle to target enterprise centers. Sun Fire production continued post-acquisition, with SPARC-based T-series models, such as those powered by the SPARC T3 processor launched in September 2010, continued production until 2012 as Oracle introduced the new lineup at its OpenWorld conference. x86-based Sun Fire servers, including high-end models such as the X4800, persisted until mid-2012, when Oracle announced the phase-out of the Sun Fire branding for new products. In 2012, remaining lines were rebranded under Oracle's nomenclature, transitioning SPARC systems to the Oracle SPARC T-series and x86 variants to the Oracle Sun Server X-series, effectively ending the Sun Fire era as a distinct product family. For instance, the Sun Fire X4800 server achieved end-of-life status in May 2012, ceasing new orders and shipments. Oracle provided legacy support for Sun Fire systems through its Premier Support program, which concluded between 2018 and 2023 for most models depending on their release date; for example, the Sun Fire X4800's Premier Support ended on April 19, 2022. Extended Support from Oracle was available for an additional three years in some cases, but for select x86 variants, third-party maintenance providers offered continued service up to 2025, ensuring operational continuity beyond official end-of-support dates. This phase-out reflected broader industry trends, as Oracle redirected resources toward cloud infrastructure and pre-integrated appliances, diminishing the role of standalone Sun Fire hardware in favor of subscription-based cloud services and hybrid systems.

Model Nomenclature

System Type Prefixes

The Sun Fire server line employed a consistent prefix system in its model nomenclature from 2001 to 2012 to denote system form factors, levels, and intended market segments, applicable across both SPARC-based and x86-based architectures. This approach facilitated rapid identification of a server's target use cases, from small-scale deployments to large enterprise environments. The "V" prefix designated volume or entry-level servers, typically low-cost, rackmount systems aimed at small and medium-sized businesses (SMBs) or departmental applications, such as the Sun Fire V20z, a 1U Opteron-based server offering basic compute and storage for cost-sensitive environments. In contrast, the "E" prefix indicated enterprise or high-end servers designed for mission-critical, large-scale operations with advanced high-availability features, exemplified by the Sun Fire E25K, a cabinet supporting up to 72 UltraSPARC IV+ processors for massive scalability. The "B" prefix denoted servers within modular for dense, shared infrastructure, as seen in the Sun Fire B200x series, which integrated multiple compute nodes into a compact for efficient resource utilization in clustered setups. Additionally, the "X" prefix was reserved for x86-specific servers, often optimized for storage or , such as the Sun Fire X4500 (codenamed Thumper), a 4U system with up to 48TB of internal storage for data-intensive workloads. The "T" prefix highlighted throughput-oriented servers emphasizing multi-core or multi-threaded designs for parallel processing, like the Sun Fire T2000, powered by the UltraSPARC T1 processor with eight cores and 32 threads to maximize application throughput under power constraints. These prefixes remained uniform across the product lines, enabling users to discern scalability and deployment suitability at a glance. Following ' 2007 partnership with , the high-end models underwent a partial rebranding to SPARC Enterprise (e.g., M-series for former E-series equivalents), yet the core Sun Fire prefix conventions persisted for continuity in naming T-series and x86 lines. This system was phased out around 2012 after Oracle's acquisition of Sun in , transitioning to simplified "Sun Server" branding that dropped the Fire designation and prefixes for newer x86 models.

Processor Suffixes and Evolution

The processor suffixes in Sun Fire model names were introduced to denote specific CPU architectures during the early expansion into x86 systems, allowing differentiation without altering established system type prefixes. In , amid a market shift toward open architectures, Sun launched its first x86-based servers using the processor, incorporating the "x" suffix in models like the Sun Fire V60x and V65x, which supported up to two processors at speeds of 2.8 to 3.2 GHz. The following year, in 2004, the "z" suffix was employed for Opteron-based variants to highlight their architecture, as in the Sun Fire V20z (dual Opteron) and V40z (quad Opteron) servers. UltraSPARC-equipped Sun Fire models, such as the V440 with up to four UltraSPARC IIIi processors, omitted any such suffix, relying solely on the base nomenclature. This suffix convention enabled clear identification of processor types alongside system form factors (e.g., "" for volume servers), supporting compatibility assessments for software and peripherals across the lineup. By preserving core prefixes, the approach minimized disruption to existing naming while signaling architectural shifts. The evolution of these suffixes emphasized simplification over time. After 2006, Sun discontinued the "x" and "z" designations, standardizing on the "X" prefix for all models regardless of or processors, as demonstrated by the 2006 Sun Fire X4100 (up to two ) and the 2007 Sun Fire X4150 (dual ). In 2007, integration with Fujitsu's Enterprise series introduced M-class naming for high-end systems, such as the M4000 with 64 VI processors, eliminating processor suffixes entirely in favor of series-based identifiers. Following 2008, Sun Fire's T-series emphasized Niagara-based (UltraSPARC T) processors without introducing new suffixes, continuing the streamlined approach in models like the T5440 with up to four UltraSPARC T2 Plus chips. This progression led to the complete abandonment of processor suffixes by 2012, aligning nomenclature with broader product unification.
