ECG068/0798 WHITE PAPER (cont.) 2...6 q The Highly Parallel System Architecture features: • Dual memory controllers. Dual memory controllers enable the processing of memory requests in parallel with a memory bandwidth of 1.07GB/sec-up to four times the bandwidth of other systems without this feature. • Dual peer PCI busses. This enables peripherals on either bus to have independent access to the system's CPUs and memory. The video server I/O load can be balanced by putting high performance peripherals such as disk controllers and graphics controllers on separate busses. I/O bandwidth of up to 267MB/sec-twice that of a single PCI bus- can be achieved. This also means that a larger number of PCI devices can be supported compared to single bus systems. q High performance, high capacity disk storage. In addition, the ProLiant 5500 supports integrated dual channel Wide-Ultra SCSI-3 disk controllers for maximum sustained video I/O throughput. Internal drive bays accommodate up to 8 hot-pluggable 1" drives or up to 6 hot-pluggable 1.6" with capacities of 9.1GB or 18.1GB per drive. Additional storage is available through the use of SCSI or Fibre Channel external disk storage options. q Large system memory expansion. The system memory of the ProLiant 5500 can be expanded from 128 MB up to 3 GB for handling high workloads of multiple concurrent video streams. q High availability options. To maximize availability with minimum downtime, the ProLiant 5500 supports hot-pluggable redundant components such as power supplies, disk drives, fans, and network interface cards. q Large number of expansion slots. There are 5 PCI and 3 shared EISA expansion slots in the ProLiant 5500 for accommodating such things as additional disk controllers and Ethernet or ATM network interface cards that may be needed in video server applications. q Rack-mount options and conversions. The Compaq ProLiant 5500 is available in tower or rack-mount configurations to accommodate small or large video server installations. The tower unit features a tower-to-rack conversion capability. q Attractive cost per stream. By using standard low cost, high-volume components, the Compaq ProLiant 5500 minimizes the cost per stream. From the Microsoft Windows NT Operating System to the industry-standard Intel Pentium processor all the way to the use of low cost high-density Dual In-line Memory Modules (DIMMs) the Compaq ProLiant 5500 provides breakthrough cost per stream for video streaming applications. Other members of the Compaq ProLiant family that also feature the Highly Parallel System Architecture and other key features needed in video server configurations include the ProLiant 3000 and the ProLiant 1600.
