Performance notesUse the information in this section to help determine the maximum number of adapters that can beplaced in a system while still maintaining optimum performance.Performance notes regarding GX++ channel adaptersTable 4 on page 9 identifies the slot placement priorities and the maximum number of specified adaptersthat can be installed for connectivity. However, for optimum performance, you might want to furtherlimit the total number of high bandwidth and extra-high bandwidth adapters. The system supports theFC 5266 GX++ dual port adapter. When plugging in these adapters, if only one adapter is beingconfigured it must be placed in the GX++ slot 2. This placement helps distribute the I/O traffic over theGX buses to the processors.PCI adapter placement rules and slot priorities for the 31E/1CSome adapters must be placed in specific PCI Express (PCIe) slots to function correctly or to performoptimally. Learn how to determine the slot to install PCI adapters for the 7/10 (31E/1C) system.PCI slot descriptionsThe 31E/1C system has five PCIe x8 G2 low-profile slots and one PCIe x4 low-profile slot. All slotssupport enhanced error handling (EEH), but are not hot pluggable. Figure 2 shows the rear view of thesystem with the location codes for the PCI adapter slots. Table 5 describes the slots. All slots in thissystem are low-profile slots only. Each PCIe is a separate PCI host bridge (PHB). The PCIe slot 1 and slot4 have an x16 connector and the other slots have an x8 connector.For the information about the maximum adapters supported on your system, see Table 6 on page 12.Figure 2.
