System architecture HP Integrity midrange servers are built around a modular architecture, with components that can be configured to effectively cover a wide range of computing needs. Both the Integrity rx7620-16 and 8620-32 Servers support a variety of system configurations, ranging from two to eight 1.6 or 1.5 GHz Intel Itanium 2 processors or from two to 16 1.1 GHz Intel Itanium 2 processors, using HP mx2 Dual-Processor Modules. Both servers can be configured as large symmetric multiproc

HP Integrity rx8620-32 Server architecture The HP Integrity rx8620-32 Server architecture builds upon that of the Integrity rx7620-16 Server with the addition of a crossbar backplane and two more cell boards. The crossbar backplane provides a non-blocking connection between up to four cells, plus connection to the external I/O resources in the HP Server Expansion Unit (SEU). Similarly to the Integrity rx7620-16 Server, the Integrity rx8620-32 Server can be configured as one 2- to 16-way (In

Within the cell, CPU-to-CC peak bandwidth is 12.8 GB/s, a greater than 50% improvement over previous-generation systems. The minimum supported cell configuration is two active processors and 2 GB of memory per cell board. The maximum configuration includes eight active processors and 64 GB memory per cell board in the Integrity rx7620-16 Server; the Integrity rx8620-32 Server supports a maximum of 16 active processors and 64 GB memory per cell board. Memory DIMM modules are sold in sets of

Cell hot-plug The HP Integrity rx7620-16 and rx8620-32 Servers support cell hot-plug. Coupled with the servers’ 1 partitioning capability , cell hot-plug allows for the servicing of cell boards within a single partition while the other partition continues normal operation. Any number of configuration changes can be made to the partition being serviced, including replacing the complete cell board, adding or deleting CPUs and memory, or even increasing or decreasing the number of cells in tha

I/O subsystem Each HP Integrity rx7620-16 and rx8620-32 Server contains an embedded high-performance I/O subsystem. In addition, the Integrity rx8620-32 Server can optionally connect to external I/O resources located in the HP SEU through a high-performance I/O cable link. The components within the I/O subsystem are the I/O controllers, internal peripheral bay, and multifunction core I/O. Basic block diagrams for the HP Integrity rx7620-16 and rx8620-32 Server I/O subsystems are shown in F

I/O controller chips The HP Integrity rx7620-16 and rx8620-32 Servers contain two master I/O controller chips located on the PCI-X backplane. Each I/O controller contains 16 high-performance, 12-bit-wide links. These links connect to 16 slave I/O controller chips supporting the PCI-X card slots and core I/O. In both systems, two links—one from each master controller—are routed through the system backplane and are dedicated to core I/O. The remaining 30 links are divided among the 16 133 MH

Core I/O The HP Integrity rx7620-16 and rx8620-32 Servers are purchased with either one or two core I/O card products. In both systems, core I/O provides console, Ultra160 SCSI, Gigabit LAN, serial, and Management Processor (MP) functionality, along with SCSI controllers for the peripheral bay. The second core I/O product can be used to enable dual partitioning, provide access to a second set of disk drives, and provide redundant MP functionality. In the HP Integrity rx8620-32 Server, the s

Figure 15. Basic core I/O card set (secondary) The Management Processor—The Management Processor (MP) is a dedicated processor located on each MP/SCSI card that simplifies and extends system management and enhances serviceability. The MP reduces or eliminates the need for the system administrator to be physically at the system to perform tasks such as diagnostics, system management, or even hard resets. Following are some of the features offered by the Integrity rx7620-16 and rx8620-3
