IOP PCI adapters

I/O processor (IOP) adapters process instructions from the server and work with IOP-controlled I/O adapters (IOAs) to control the I/O devices.

Table 1 shows the IOP adapters that are supported on expansion units connected to the 9406-MMA, 9407-M15, 9408-M25, and 9409-M50 servers.

Expansion unit 5796 does not support IOPs.

For more information about expansion units that can be connected to a machine type 940x server, see Placing an adapter in an expansion unit and Configuration tables for system units and expansion units.

Note: The internal PCI-X DDR and PCIe slots on machine type 940x servers are designed for IOPless adapters. IOP adapters, and IOA adapters that require an IOP adapter, are not supported in the internal slots..
