PCI-Based I/O Hardware • Slot 7 is on its own bus. Therefore, its bandwidth is not affected by a card placed in another slot. The following illustration shows the layout of the PCI Expansion Rack or the PCI Channel Module Figure 1–23. PCI Expansion Rack Layout 1.3.9. Configuration Restriction Dorado 300 and Dorado 400 For the Dorado 300 and 400, the IOP controls two onboard slots. If each onboard slot contains a link to an expansion rack, then up to 14 HBAs or NICs could be controlled by a single IOP (7 x 2). If all the HBAs/NICs are dual-ported cards, then the IOP could theoretically have 28 ports (channels). The maximum number of ports per IOP is actually less than the theoretical hardware limit of 28. The limits are the following: • 16 ports (channels) for HBAs • 14 ports (channels) for NICs The firmware for the SIOP (HBAs) and the firmware for the CIOP (NICs) are different. However, they both initialize in the same way. As they detect a card, they count the number of possible connections. For a dual port card, the possible number is two. 1–30 3839 6586–010
PCI-Based I/O Hardware Once the maximum number of ports is encountered, error conditions occur upon detection of the next card. If you have all dual-port cards, you are limited to • 8 HBAs per SIOP • 7 NICs per CIOP Note: CIOP is not supported on Dorado 400, 4000, or 4100. If you have a combination of single-port and dual-port cards, you can have more than the number of cards shown here, but you are still limited by the number of ports as defined above. The port (channel) limitation is true whether or not you have anything connected to the port. Since the limitation determination occurs at microcode initialization, you cannot down the unused channel and you must configure it in SCMS II. Dorado 700, Dorado 4000, and Dorado 4100 For the Dorado 700, 4000, and 4100 servers, the PCIOP-E only connects to one PCI Channel Module with 7 slots and a maximum of 14 ports. To prevent one of the SCSI Ports from failing to initialize in certain configurations, the SCSI HBA should be placed in slot 1, with any subsequent SCSI HBAs placed in the PCI Channel Module according to the guidelines in the following table. An HBA of a different type (Fibre or SBCON) should be placed in the rack ahead (in the scan order) of the SCSI HBA. The IOP scans the PCI Channel Module PCI bus from slot 6, slot 5, slot 7, slot 4, slot 3, slot 2, and then slot 1. For example, if the SCSI HBA is placed in slot 1, a FIBRE should be placed in slot 6 or an SBCON card should be placed in slot 2. If there is only one SCSI card installed in the rack, the IxyCz1 port on that SCSI card will be unusable. For example, if there are SCSI HBAs in slots 1 to 4 (IxyC10/11 to IxyC40/41), the IxyC41 will be unusable. For the XIOP, only one Myrinet PCI card (MYR1001-P64) can be installed in the expansion rack and no other PCI cards can be installed in this rack. The Myrinet card must be installed in slots 1 to 4, or slot 7. Slot 7 is the preferred location as there is one less PCI Bridge to go through to reach the Myrinet card. If your previously shipped Dorado Platform has the Myrinet card in slots 1 to 4, there is no need to move the card to slot 7. If the card is moved, a new ODB (PTN) file will need to be generated and loaded. The guidelines for populating the expansion rack are listed in the following table. HBA Slot Order SCSI 1, 2, 3, 4, 7, 5, 6 SBCON 1, 2, 3, 4, 7 CAVIUM 6, 5, 7, 4, 3, 2, 1 3839 6586–010 1–31
