Dorado 780 and Dorado 790
PCI-Based I/O Hardware
• Faster 2200 processor (about 15 percent faster than Dorado 740 and Dorado 750)
• PCI-X based PCIOP-E I/O processor and Channel cards
• Support for External I/O with a maximum of six IOPs in a Remote I/O Module
(SIOP, CIOP, and XIOP)
• Support for XPC-L connectivity through the PCIOP-E version of the XIOP
Dorado 700 series I/O Configuration
The I/O for the Dorado 700 Series can either be Internal with a maximum of four IOP
cards for each cell (740 and 750) or External with a maximum of six IOP cards for each
Remote I/O Module (780 and 790).
The Internal I/O contains one to four I/O Processor units (PCIOP-E) with each PCIOP-E
connecting to a PCI Expansion Rack. The PCI Expansion Rack can contain either
standard channel cards or NIC cards. Each PCIOP-E requires a separate expansion rack
and can have only NIC cards or storage HBA cards, but cannot have both in the same
rack.
The External I/O is located in the Remote I/O Module. The Remote I/O Module
contains one to six I/O Processor units (PCIOP-E). The same PCI Expansion Racks
connect to the external I/O processors.
The Internal I/O or the Remote I/O Module does not contain PCI Channel cards. They
are located in the PCI Expansion Racks.
Notes:
• Internal I/O DVD – The PCIOP-E card used for connection to the DVD drive can
only be inserted in IOPx1 slot when viewed from the rear of the IP Cell, due to
cable routing within the cell. The DVD appears as PDID=61392 (xEFD0 or
167720), CU address=0, Device address =0.
• External I/O DVD – The PCIOP-E card used for connection to the DVD drive can
only be inserted in IOPx5 slot when viewed from the rear of the Remote I/O
Module, due to cable routing within the cell. The DVD appears as PDID=61392
(xEFD0 or 167720), CU address=0, Device address =0.
Each PCIOP-E (SIOP, CIOP, and XIOP) requires two cables, a communications cable,
and an I/O cable. The Remote I/O Module contains the platform logic for primary PCI
buses. These PCI buses are where the PCIOP-E boards are attached.
The PCIOP-E contains the I/O processor (IOP) and the 36-bit data formatter needed to
perform the I/O operations. The primary PCI bus is connected to the memory side of
the formatter and IOP bridges. A secondary PCI bus is attached to the channel side of
the bridges. PCI cards that support the IDE DVD drive and the three inbuilt SAS drives
must be installed in one of the available PCI slots to drive these interfaces.
The PCIOP-E and PCI cards can be hot replaced, but only if their status is DOWN.
