Introduction The seventh generation HP ProLiant DL580 Server series stands out as a major advancement over earlier generations of four-socket servers. The DL580 G7 (Figure 1) features improved HP architecture, advanced RAS features, enhanced HP Integrated Lights-Out (iLO 3) remote management capabilities, and the latest technology- based hardware options. The DL580 G7 also gives you excellent system performance using Intel® Xeon® E7 series processors, and the 7500 series memory architecture, a l

The DL580 G7 uses HP’s leading “Sea of Sensors” technology to track and manage the temperature and health of both individual subsystems and field-replaceable units (FRU). At a reduced level of power and noise, a set of four redundant (3+1) fans run efficiently and cool the DL580 G7 reliably. The reliability, serviceability, and manageability features in the server have improved with the development of components, interconnect fault tolerance, structured design and validation as well as the renew

Memory—With the support for a new Memory Cartridge and 32 GB DDR3 DIMM, the DL580 G7 supports 2TB of memory capacity. In addition, by supporting low-voltage DIMMs, the DL580 G7 reduces power consumption when compared with previous generations. Expansion Slots—The DL580 G7 features PCI Express Gen 2.0. This achi

Memory Subsystem Architecture The HP ProLiant DL580 G7 provides a 2TB memory footprint and supports up to 64 DDR3 RDIMMs. Each of the server’s four processors receives 16 RDIMM sockets in two easily serviceable memory cartridges. The DL580 G7 supports 2, 4, 8, 16, and 32GB RDIMMs. The server incorporates four processors. Each processor contains two memory controllers as shown above in Figure 2. Each memory controller has two Scalable Memory Interface (SMI) links operating in lockstep. Each SMI l

The above Non-Hemisphere Example 5 and Example 6 illustrate: Each memory controller must have a memory cartridge DIMM configurations of each memory cartridge connected to controller 1 and 2 of a processor must be identical. Note that “Example 4” is a Hemisphere configuration. The two cartridges connected to each processor share identical configurations, but Cartridge 1 and Cartridge 2 are not identical to Cartridge 3 and Cartridge 4.

Populate each DDR3 channel in each memory cartridge. To achieve this, the minimum DIMM count per cartridge is four DIMMs installed in DIMM pair locations A and B. This is the second largest contributor to performance. Use dual-rank DIMMs for significantly better performance than that of single-rank DIMMs. Quad-rank DIMMs provide a greater performance boost. The number of ranks per DIMMs is the third largest contributor to performance. Use all installed processors in Hemisphere mode for the

When the system enables online sparing, the first ranked DIMM pair of 1A/8A are set aside as the sparing ranks, reducing available memory. If a DIMM rank on either of the SMI buses exceeds its correctable ECC threshold, the contents of the failing DIMM ranks go to the spare DIMM ranks. Once the copy is complete, all memory accesses to the previous failing DIMM ranks go to the spare DIMM ranks. During normal operation, there is no performance penalty for rank-sparing. Upon detection of a frequent

In memory expansion architecture, each processor has two embedded memory controllers. Each memory controller controls two high-speed scalable memory interfaces (SMI). Each SMI link expands to two DDR3 buses via a scalable memory buffer (SMB). Each memory controller runs its two SMI links in lockstep. Memory expansion architecture furnishes a level of fault tolerance to sustain the failure of any DRAM device within any pair of lockstep DIMMs. This memory subsystem design supplies enhanced perform
