CMT provides real value since it increases the ability of the execution pipeline to do actual work on any given clock cycle. Use of the processor pipeline is greatly enhanced because a number of execution threads now share its resources. The negative effects of memory latency are effectively masked, because the processor and memory subsystems remain active in parallel to the processor execution pipeline. Since these individual processor cores implement much-simpler pipelines that focus on scaling with threads rather than frequency (emphasizing TLP over ILP), they are also substantially cooler and require significantly less electrical energy to operate. This innovative approach results in CoolThreads processor technology—multiple physical instruction execution Oracle White Paper—Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/T5240 Server Architecture pipelines (one for each core), with multiple active thread contexts per core. In addition, UltraSPARC T2 and UltraSPARC T2 Plus processors feature two execution pipelines per core to further boost scalability.

The UltraSPARC T2 and T2 Plus Processors Unlike complex single-threaded processors, CMT processors use the available transistor budget to implement multiple hardware multithreaded processor cores on a chip die. The UltraSPARC T2 and UltraSPARC T2 Plus processors take the CMT model to the next level, providing up to eight cores per processor, with each core supporting up to eight threads via two independent pipelines—effectively doubling the throughput of the UltraSPARC T1 processor without raising the clock frequency. In addition, these processors use the increased transistor budget resulting from the use of a 65 nm silicon technology to implement the industry’s first massively threaded

system–on-a-chip (SoC), with a single processor die hosting:

Up to 64 threads per processor (up to eight cores supporting eight threads each)  On-chip Level 1 and Level 2 caches  Per-core floating-point capabilities  Per-core cryptographic acceleration  Two on-chip 10 Gigabit Ethernet (GbE) interfaces (UltraSPARC T2 processor only)  On-chip PCI Express (PCIe) interface  On-chip cache coherency logic and links (UltraSPARC T2 Plus processor only)  Through SoC design, the UltraSPARC T2 processor significantly enhances the general-purpose nature of the CPU—building in eight floating-point units (one per core). Enhanced floatingpoint capabilities open the UltraSPARC T2 to the world of compute-intensive applications as well as the traditionally CMT-friendly data center throughput applications. No-cost security and cryptographic acceleration is provided by the on-chip, per-core streaming accelerators. In addition, the ability to move data in and out of the UltraSPARC T2 processor is significantly aided by an integrated PCIe interface and dual 10 GbE interfaces on the UltraSPARC T2 processor. The UltraSPARC T2 Plus processor replaces the dual 10 GbE interfaces with cache coherency logic and links that facilitate a multisocket, glueless system designs.

Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/5240 Servers Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/T5240 servers (Figure 2) are all designed to leverage the considerable resources of the UltraSPARC T2 and UltraSPARC T2 Plus processors in the form of cost-effective, generalpurpose platforms. Oracle's Sun SPARC Enterprise T5120/T5220 servers deliver up to twice the throughput of their predecessors, while leading competitors in terms of performance, Oracle White Paper—Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/T5240 Server Architecture performance per watt, and SWaP performance (as evaluated by the Space, Watts, and Performance metric detailed later in this section). Oracle's Sun SPARC Enterprise T5140/T5240 servers extend this scalability by adding dual sockets for UltraSPARC T2 Plus processors and considerably large memory support. All these systems also extend the benefits of CMT from multithreaded commercial workloads into technical workloads rich in floating-point operations.

Figure 2. Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/T5240 servers are all designed to leverage the considerable resources of the UltraSPARC T2 and UltraSPARC T2 Plus processors.

Overview With support for up to 128 threads, large memory, cryptographic acceleration, and integrated onchip I/O technology, these servers represent a departure from traditional system design. Oracle's Sun SPARC Enterprise T5120/T5140 servers are ideal for providing high throughput within significant power, cooling, and space constraints. Oracle's Sun SPARC Enterprise T5120 server supports a single UltraSPARC T2 processor whereas Oracle's Sun SPARC Enterprise T5140 Oracle White Paper—Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/T5240 Server Architecture supports two UltraSPARC T2 Plus processors. Both systems feature a compact and powerefficient one rack unit (1RU) rack mount package. As compute nodes within massive, horizontally scaled environments, Oracle's Sun SPARC Enterprise T5120/T5140 servers can help provide a substantial building block for application tier, Web services, or even high-performance computing (HPC) infrastructure. Network infrastructure applications such as portal, directory, network identity, file service, and backup are all a good fit for these servers.





Oracle's Sun SPARC Enterprise T5220/T5240 servers provide both throughput as well as expandability, with extra I/O and internal disk options afforded by the 2RU rack mount form factor. Oracle's Sun SPARC Enterprise T5220 servers support a single UltraSPARC T2 processor whereas Oracle's Sun SPARC Enterprise T5240 servers support dual UltraSPARC T2 Plus processors. With greater I/O and internal disk, typical workloads include demanding midtier application server deployments or Web-tier and application-tier consolidation and virtualization projects requiring maximum uptime with future growth and integration into diverse environments. Oracle's Sun SPARC Enterprise T5220/T5240 servers are also ideal for online transaction processing (OLTP) database deployments.

Designed to complement each other, as well as the rest of Oracle’s server product line, Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/T5240 servers address the dynamic needs of the modern data center.

Efficient and predictable scalability. With support for 64 threads and large memories,  Oracle's Sun SPARC Enterprise T5120/T5220 servers are the first to use the 10 GbE, I/O, and cryptographic acceleration provided directly on the UltraSPARC T2 processor silicon itself. This approach provides leading levels of performance and scalability with extremely high levels of power, heat, and space efficiency.

Oracle's Sun SPARC Enterprise T5140/T5240 servers extend this breakthrough compute and memory density, delivering up to 128 threads in as little as 1RU, while typically consuming less than 700 watts of power. These systems also deliver twice the I/O bandwidth of the Sun SPARC T5120/T5220 servers by providing a PCIe root complex associated with each socket.

Accelerated time to market. Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun  SPARC Enterprise T5140/T5240 servers running Oracle Solaris provide full binary compatibility with earlier UltraSPARC systems, preserving investments and rapid time to market. The CoolTools for SPARC help accelerate application selection, profiling, testing, tuning, debugging, and the deployment of key applications on CMT systems.

Industry-leading tools for virtualization and consolidation. Oracle’s chip multithreading  (CMT) technology is ideal for consolidation, providing low-level multithreading support for virtualization at every layer of the technology stack. Oracle’s Virtual Machine for SPARC (OVMS) technology exploits the UltraSPARC T2 and UltraSPARC T2 Plus processor’s up to 64 threads per socket, offering multiple guest operating system instances. In addition, Oracle Solaris Containers provide virtualization within a single Oracle Solaris instance. The advanced Oracle White Paper—Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/T5240 Server Architecture Oracle Solaris ZFS file system provides storage virtualization for storage and considerable scalability.

System and data center reliability. Reliability is key to keeping applications available and  costs down. With the greater levels of integration provided by an SoC design, Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/T5240 servers offer greatly reduced part counts, and provide commensurately higher levels of reliability, availability, and serviceability (RAS). Lower power consumption and higher performance per watt greatly reduce generated heat loads and the associated issues they cause. Technologies such as Solaris Predictive Self Healing are integrated with the hardware, and help keep systems available.

A tradition of leading ecoefficiency. Oracle's Sun SPARC Enterprise T1000 and Oracle's  Sun SPARC Enterprise T2000 servers were the industry's first ecoresponsible servers. Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/T5240 servers continue this tradition by offering the best performance and performance per watt across a wide range of commercial and technical workloads. In addition, the UltraSPARC T2 processor was the first processor to incorporate unique power management features at both core and memory levels of the processor.

Zero-cost security. Providing secure communications and data protection has never been  more important, with attempted electronic intrusion and theft at an all-time high. With up to eight integrated cryptographic accelerators on each UltraSPARC T2 and UltraSPARC T2 Plus processor, there is simply no need to send plain text on the network or store plain text in storage systems. Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/T5240 servers support many more crypto operations per second than competitive systems with dedicated crypto accelerator cards—all with minimal impact to system overhead.

Simplified management. Each of Oracle's Sun SPARC Enterprise T5120/T5220 and  Oracle's Sun SPARC Enterprise T5140/T5240 server provides an Integrated Lights Out Manager (ILOM) service processor, compatible with Oracle’s x64 servers. Integrated Lights Out Manager provides a command-line interface (CLI), a Web-based graphical user interface (GUI), and Intelligent Platform Management Interface (IPMI) functionality to aid with out-ofband monitoring and administration. Integrated Lights Out Manager also provides an Advanced Lights Out Management (ALOM) backward-compatibility mode for administrators familiar with Sun Fire and Oracle's Sun SPARC Enterprise T1000 and Oracle's Sun SPARC Enterprise T2000 servers.

The industry’s most open platform. Oracle's Sun SPARC Enterprise servers are the  industry’s most open platforms, providing the only mainstream processor and hypervisor offered under the GNU General Public License (GPL). These systems offer a choice of operating systems, including Oracle Solaris, Linux, and BSD variants. Oracle Solaris is free and open, offering full binary compatibility and enterprise-class features.

Oracle White Paper—Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/T5240 Server Architecture Innovative System Design Beyond the capabilities of individual systems, Oracle understands that data centers have unique and pressing needs that require attention on the part of system designers. Density, performance, and scalability are all essential considerations, but systems must also be serviceable and fit in with modern data center strategies that consider power, cooling, and serviceability. Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's Sun SPARC Enterprise T5140/T5240 servers share an innovative design philosophy that extends across Oracle’s volume x64 and SPARC server platforms. Principles of this philosophy include Maximum compute density. Oracle’s volume servers provide leading density in terms of  CPU cores, memory, storage and I/O. This focus on density often lets Oracle’s 1RU rack mount servers replace competitive 2RU servers, for a 50 percent space savings.

Continued investment protection. Oracle designs for maximum investment protection.

 Even with breakthrough technology such as chip multithreaded processors, applications simply run without modification.

Leading storage capacity. Oracle’s volume servers provide leading density and flexible  RAID options. Smaller disk drives and innovations in structure, airway, and carrier design allow more disk capacity in smaller spaces, while enhancing system airflow.

Common, shared management. Oracle's Sun SPARC Enterprise T5120/T5220 and Oracle's  Sun SPARC Enterprise T5140/T5240 servers are designed for ease of management and serviceability with service processors shared by other Oracle volume server platforms. Systems and components are designed for easy identification, and hot-swap components facilitate online replacement.

Common chassis design. Shared chassis design leverages key system innovations across  multiple architectures, provides for common components and subassemblies, and greatly simplifies administration for those deploying multiple processor architectures.
