The server supports two internal SBAs. The SBAs generate 32 rope busses (16 per SBA). The 32 available internal rope busses are divided in the following manner:

•Two ropes are routed as single rope bundles to support PCI-2x Turbo (264 MB/sec. bandwidth, 64-bit transfers at 33 MHz) for the MP Core I/O boards for SCSI/LAN.

•Two ropes are routed as single rope bundles to two LBAs to support two slots operating at PCI-2x for MP/SCSI.

•The remaining 28 ropes are bundled in two rope pairs to 14 LBAs to support 14 slots operating at PCI-4x (528 MB/sec., 64-bit transfers at 66 MHz).

The hp rp7405/rp7410 uses Hewlett-Packard’s proprietary adaptive signaling concept, also known as the Universal PCI slot concept (not to be confused with the Universal PCI card). Circuitry on the backplane senses a standard connector, keyed for 5V, to determine the type of the cards inserted. The circuitry controls the voltage rail supplied to the connector for powering the card’s I/O pads, VIO. The card can either be of the 5V only, or universal type. 5V only cards require VIO to be 5V, whereas universal cards operate 5V as well as 3.3V. To take advantage of the 66-MHz potential of universal cards, one must operate those cards at 3.3V. The control circuitry on the backplane, therefore, provides 5V to the slot when a 5V-only card is present, or 3.3V when a universal card is present. Firmware controls the setting of the slot’s clock rate.

The HP RP7405 and RP7410 are high-performance servers in the HP Integrity line, specifically designed for mission-critical applications. These servers are built on the Itanium architecture and showcase HP's commitment to reliability, scalability, and performance. Targeted primarily at the enterprise market, both models are ideal for data-intensive workloads, virtualization, and large databases.

One of the standout features of the RP7405 and RP7410 is their robust architecture. The servers utilize HP's NonStop technology, ensuring high availability and fault tolerance. This architecture is designed to provide continuous uptime, which is crucial for businesses dependent on uninterrupted access to their data and applications. The RP7405 supports up to 4 processors, while the RP7410 can accommodate up to 8 processors, allowing for enhanced compute power and the ability to handle increasingly demanding workloads.

In terms of memory, the RP7405 and RP7410 support significant RAM configurations, making them capable of handling large memory-intensive applications. They are equipped with advanced memory management technology, including ECC (Error-Correcting Code) memory, which helps to detect and correct data corruption, thereby enhancing system reliability.

The servers employ HP's Virtual Partition (vPars) technology, which allows for efficient server consolidation by enabling multiple virtual servers to operate on a single physical machine. This capability enhances resource utilization and simplifies management, thus reducing IT costs while maximizing performance.

HP's Serviceguard clustering software is integrated into both servers, offering enhanced availability through active-active clustering and failover capabilities. This software ensures that workloads can be seamlessly transitioned between servers in the event of hardware failures or maintenance, further minimizing downtime.

Security is also a paramount consideration with the HP RP7405 and RP7410. The servers come equipped with advanced security features, including secure boot, encryption, and an array of compliance certifications, ensuring that sensitive data is protected against unauthorized access.

Additionally, the servers support a wide range of operating systems, including HP-UX, which is optimized for the Itanium architecture. This flexibility allows organizations to choose the operating environment that best suits their application needs.

In conclusion, the HP RP7405 and RP7410 are powerful servers designed for high-performance applications in enterprise environments. With their advanced architecture, extensive memory support, virtualization capabilities, and robust security features, these servers stand out as reliable solutions for organizations seeking to enhance their IT infrastructure while ensuring high availability and performance.
