Theory of Operation
I

O and Intelligent RAID Controllers
Several information technology industry leaders have formed a Special
Interest Group (SIG) to promote intelligent I/O standards for the entire
industry. These standards, referred to as the Intelligent I/O (I
2
O)
specification, address the performance issues caused by I/O interrupts
sent to the host CPU and the need for unique drivers for every
combination of I/O device and operating system.
I
2
O-compliant products include both intelligent host adapters and RAID
controllers (those incorporating a microprocessor) and non-intelligent
host adapters and RAID controllers (those without a microprocessor).
Maximizing a servers potential requires more than just I
2
O. It requires an
intelligent adapter or controller with a dedicated microprocessor.
Intelligent I/O (both intelligent adapters and RAID controllers) has been
available from DPT for two decades. The I
2
O-compliant SmartRAID V
controllers are the latest intelligent adapter technology, with fast RISC-
based embedded I/O processors and our new Pipelined Parallel
Processing (P
3
) technology.
The following illustration depicts the two-part device driver architecture
used by I
2
O compliant products. This design allows for much faster device
driver development for specific operating system platforms. For additional
information, see the SmartRAID V Architecture section in this chapter.
