  • Page 2: Abstract

    ProLiant ML530 High-Performance Technologies abstract The ProLiant ML530 Generation 2 (G2) server features new technologies that improve on the performance, scalability, fault tolerance, and manageability of the first generation ProLiant ML530 server. A discussion of all these technology improvements is beyond the scope of this document.

  • Page 3: System Architecture

    ProLiant ML530 High-Performance Technologies system Figure 2 illustrates the balanced system architecture of the ProLiant ML530 G2 server. At the heart of the server architecture is the enterprise-class ServerWorks GC HE chipset, architecture which controls 3.2 GB/s of data transfer between the processor, memory, and input/output (I/O) subsystems.

  • Page 4: Smaller Feature Size

    ProLiant ML530 High-Performance Technologies figure 3. ProLiant ML530 G2 processor subsystem architecture smaller feature size The Intel Xeon Processor is built with a 130-nanometer (0.13-micron) process to allow higher frequencies and better performance. The manufacturing term 0.13 micron refers to the circuit (feature) size. Feature size is a major limiting factor in processing speed. The smaller the feature size, the more transistors are packed into the circuit.
  • Page 5 ProLiant ML530 High-Performance Technologies figure 4. Hyper-Threading technology In a multiprocessing system, the OS manages the tasks performed by all processors in the system. To take advantage of multiple processors, applications must be multi- threaded, which means they must be designed to be split into multiple streams of instructions, or threads.

  • Page 6: Level 2 Advanced Transfer Cache

    ProLiant ML530 High-Performance Technologies allows Windows .NET to resolve logical processors to their associated physical processors. In summary, OSs that support Hyper-Threading include: Microsoft Windows 2000 Server (counts logical processors) • Microsoft .NET Server (uses all logical processors, regardless of physical count) •...

  • Page 7: 400-Mhz Front Side Bus

    ProLiant ML530 High-Performance Technologies the Pentium III processor. As a result, there is greater chance of a cache hit for any given memory request. When a cache hit occurs in the L2 cache, the data is transferred at 2.8 GHz to the processor core along a 32-byte interface on each core clock cycle.

  • Page 8: Memory Subsystem

    The other four REMCs control the data transfers to and from the DIMMs. They serve as the bridge between the DDR memory bus and the system bus. figure 7. architecture of the ProLiant ML530 memory subsystem For more information, see Compaq Advanced Memory Protection Technologies, document number TC020607TB available online at ftp://ftp.compaq.com/pub/supportinformation/papers/tc020607tb_rev0_us.pdf.

  • Page 9: Standard Configuration

    ProLiant ML530 High-Performance Technologies standard The server comes standard with two 512-MB, DDR SDRAM DIMMs in bank A (Figure 8) for a total of 1 GB of system memory. Because the system uses 2-way interleaving, the configuration DIMMs must be installed in pairs, one bank at a time. The DIMMS in each bank must be of the same type and capacity or the performance of the memory subsystem will be degraded.

  • Page 10: I/O Subsystem

    ProLiant ML530 High-Performance Technologies In addition to the requested data, the controllers retrieve data from subsequent sequential memory addresses on both DIMMs in anticipation of future data requests. The retrieved blocks of data are merged together in 128-bit lines on the memory bus. The data is sent to the processor's L2 cache as four 128-bit lines (512 bits) to match the cache line size in the Intel Xeon Processor.

    ProLiant ML530 High-Performance Technologies figure 11. internal storage in the ProLiant ML530 G2 server quad-peer PCI-X The quad-peer PCI-X architecture consists of four 64-bit, 100-MHz PCI-X bus segments controlled by two PCI-X Bridges. The first PCI-X bridge provides PCI-X Hot Plug capability architecture to slots 1 through 4.

  • Page 13: Optimum Uses For The Proliant Ml530 G2 Server

    ProLiant ML530 High-Performance Technologies segment. For example, if one of the bus segments with two slots is populated with a 66- MHz adapter and a 100-MHz adapter, the maximum frequency of that bus segment will be 66 MHz. This means that the slowest adapter card, such as a 33-MHz, 32-bit RILOE card, should be put in slot 7 where it cannot slow down any other adapter cards.

  • Page 14: Conclusion

    ProLiant ML530 High-Performance Technologies conclusion The ProLiant ML530 G2 server is a mid-range departmental server optimized for intensive data center and remote office environments. It incorporates new technologies that improve upon the performance, scalability, fault tolerance, and manageability of the first generation ProLiant ML530 server.
