Compaq AlphaServer DS10 Systems The Compaq AlphaServer DS10 system is an entry-level For more information on Compaq AlphaServer DS10 system offering 64-bit computing with the Alpha processor. systems, see This single processor system is ideal for ISP/Internet appli- http://www.compaq.com/alphaserver cations, telecom applications, software development, and replicated site applications. The 3-U system box can be mounted in a cabinet or used on a desktop.
Third-Generation Alpha Chip The third generation of the Alpha microprocessor, the Alpha 21264, is a superscalar, superpipelined implementation of the Alpha architecture. The first offering of this chip, which was manufactured using the CMOS-6 process, was known as EV6 and now the EV67 (21264A) chip is available, which uses the CMOS-7 process. Over 15.2 million transistors are on one die.
Architecture The traditional bus interconnect has been replaced by a switchbased interconnect system. With a bus design, the processors, memory, and I/O modules share the bus. As the number of bus users increases, the transactions interfere with one another, increasing latency and decreasing aggregate bandwidth. However, with a switch-based system there is no degradation in performance as the number of CPUs, memory, and I/O users increase. Although the users increase, the speed is maintained.
System Board The interconnect switch is implemented on the system board by the chipset consisting of one C-chip, one P-chip, and two D-chips. The chipset provides the data and address path between the CPU, memory, and the I/O subsystem. into the system board is the logic needed for all the ports shown on the left side of the module, including the two Ethernet ports, and also for the two IDE connectors. Jumpers on the board allow you to change the action of the Halt button and disable the RMC timer.
Memory Memory throughput is maximized by the following features: • 128-bit wide memory data bus • Very low memory latency (120 ns) and high bandwidth with 12 ns clock • ECC memory Memory Configuration • • • Systems come with one memory option (two DIMMs) installed in Bank 0. Both DIMMs in a bank must be the same type and size. A second set of DIMMs can be added. The switch interconnect can move a large amount of data over the memory data bus. The data bus is 128 bits wide (16 bytes).
System I/O • The industry-standard PCI bus is the number one choice for high-performance I/O options, such as disk storage and highperformance video applications. • • Supports three address spaces: PCI I/O, PCI memory, and PCI configuration space Supports byte/word, tri-byte, and longword operations Exists in noncached address space only The PCI bus implementation has the following characteristics: • Fully compliant with the PCI Version 2.
System Control Close monitoring and control of the system environment and hardware is done by the remote management console (RMC). This logic allows the system operator to perform console operations remotely using a dial-in modem. The RMC logic is implemented using a PIC17C44 microprocessor on the system board. The RMC firmware code resides on the microprocessor and in flash memory.
Server Management Reliability and Availability Features The AlphaServer products support important operational and platform management requirements. The AlphaServer DS10 system achieves an unparalleled level of reliability and availability through the careful application of technologies that balance redundancy, error correction, and fault management. Reliability and availability features are built into the CPU, memory, and I/O, and implemented at the system level.
supply has a fan. If the temperature rises, the system fan speeds up; or if necessary to prevent damage, the system shuts down. OpenVMS cluster systems use the CI, SCSI, Ethernet, FDDI, and Memory Channel as the interconnect between disks and the system. Error handling. Parity and other error conditions are detected on the PCI bus. The memory checking scheme corrects singlebit errors and detects double-bit errors.
