I/O devices

I/O devices allow your managed system to gather, store, and transmit data. I/O devices are found in the server unit itself and in expansion units that are attached to the server. I/O devices can be embedded into the unit, or they can be installed into physical slots.

Not all types of I/O devices are supported for all operating systems or on all server models. For example, Switch Network Interface (SNI) adapters are supported only on certain server models, and are not supported for IBM® i logical partitions. Also, I/O processors (IOPs) are supported only on IBM i logical partitions.

Attention: Some PCI adapters and imbedded controllers require multiple PCI or PCI-E slots to be associated with them. Carefully review the PCI or PCI-E slot assignments for each logical partition to ensure that the slot configuration of the logical partition meets the adapter functional requirements. For details, see Managing PCI adapters and PCI adapter placement for machine types 82xx and 91xx or PCI adapter placement for machine type 94xx.
