Smart IOA Performance with External Storage Performance

Smart Fibre Channel IOA (IOPless Fibre Channel) is a new hardware architecture for Power™ Systems with IBM i (formerly known as i5/OS) specifically designed to address some of the external storage performance limitations seen in the past. The smart IOA architecture uses new Fibre Channel IOAs to connect to the external storage. An IOA is an I/O adapter that is connecting to the storage device. The IOA can either support fibre channel or parallel SCSI protocol. The IOP is a daughter card placed in the Power server that performs I/O processing, as the name implies smart IOAs or IOPless IOAs do not require an I/O processor card to offload the management of the data. Instead the CPU manages the I/O and communicates directly with the IOA. This paper will show lab results of the DS8300 connected to the System i platform comparing smart IOA operation to the traditional IOP based architecture. This will provide the reader with insight into the potential performance improvements that may accrue when implementing external disk storage with smart IOAs.
