| AV 25000 QuickClusters bring together the scalability of ccNUMA and the high availability of the DG/UX operating system's clustering technology in a single easy-to-order and easy-to-deploy configuration. Combine the scalability of ccNUMA (cache-coherent non-uniform memory access) with the high availability of the DG/UX cluster system Simplify cluster installation by packaging hardware, software, and implementation services. Onsite implementation services included to ensure fast and trouble-free deployment. Configured and tested at the factory that is available in 4x2 (four processor by two node), 8x2, and 16x2 easily upgradable configurations. Highly expandable cluster nodes grow with business needs up to: 64 Pentium II Xeon processors 64 GB of memory 144 PCI slots. Supports large OLTP, ERP, and data warehousing applications Features CLARiiON disk arrays and an on-line back-up option. Optimized for ccNUMA architecture, allowing applications to transparently benefit from ccNUMA performance and scalability Clustered systems present a single-system image to administrators and users Facilitates rolling software upgrades The AV 25000 ccNUMA server is the new high end of the AViiON product line, bring new levels of scalability in processors, memory, and I/O to Data General's family of enterprise-class servers. With third-generation NUMALiiNE™ technology based on Intel's high-performance Pentium II Xeon processor, the AV 25000 augments the field-proven AV 20000 as the server of choice for the largest OLTP, ERP, or data warehousing applications. The AV 25000, built from four-processor Scalable Building Blocks (SBBs), is available in configurations ranging from four to 64 Pentium II Xeon processors. This highly modular design enables scalable, balanced system performance and incremental upgrades in processor, memory, I/O, and interconnect to support business expansion, as needed. The AV 25000 also offers industry-leading investment protection by allowing new Pentium II Xeon-based hardware to be combined with installed AV 20000 Pentium Pro-based system components in a single system running a single copy of the operating system. The AV 25000 achieves excellent scalability, easy upgradability, and industry-leading price/performance through the user of cache-coherent Non-Uniform Memory Access (ccNUMA) architecture, an extension to SMP, that is the foundation for next-generation, large-scale systems. Data General's ccNUMA architecture, capable of supporting up to 1,024 processors, is implemented in the AV 25000 as commodity processing building blocks based on Standard High-Volume (SHV) motherboards, interconnected by a high-speed link. Each block incorporates a quad-processor motherboard, I/O subsystem with nine PCI slots, 512 MB to 8 GB of memory, N+1 hot-swappable power and cooling, and SCI interconnect hardware. Built around industry standards, the AV 25000 uses the latest Intel enterprise server technology and will continue to aggressively incorporate future technology enhancements. The ccNUMA architecture combines the best features of SMP and MPP systems. Like MPP (massively parallel processing) systems, ccNUMA systems' I/O and memory scale linerarly as processing building blocks are added, and there is no single backplane bus. Like SMP servers, ccNUMA systems maintain unified, global coherent memory, with all resources managed by a single copy of the operating system. As a result, today's SMP applications run on ccNUMA systems without change, and new applications can be developed without extensive re-tooling. A hardware-based cache coherency scheme ensures that data held in memory is consistent on a system-wide basis. The AV 25000 is Data General's third-generation of ccNUMA systems. Data General pioneered the user of the ccNUMA architecture in commercial computer systems with the introduction of the AV 10000 in 1995. To date, Data General has deployed more than 400 ccNUMA servers, supporting our customers' most demanding mission-critical applications. |
