Runs RAID software on
internal MIPS
The BCM8603 is a complete PCI-X/PCI-Express to the SAS/SATA-II 3-
Gbit RAID-on-chip (ROC) solution that significantly reduces CPU
utilization, system design time, and complexity. The high-performance
ports support 3-Gbit SAS and 1.5-Gbit/3-Gbit SATA-II disk drives. In
addition to integrating all hardware necessary to implement high-
performance RAID and multiport SAS/SATA connectivity, the
BCM8603 integrates a complete RAID stack that runs on the internal
MIPS® uP, representing a complete subsystem solution that can be easily
integrated into a server or external storage system.
Support for battery-backed write cache provides data protection and
integrity by supplying power to the DDR cache memory containing write
data in the case of power failure.
A 1.0 compliant Low Pin Count (LPC) interface is available to connect
the BCM8603 to an external Flash/ROM. Four pins are used to
implement an SGIO interface for drive activity and general purpose I/O.
Dual I2C interfaces running are available to communicate with an
external enclosure management device or a serial EEPROM.
Applications
The BCM8603 device communicates with the host using one of two
flexible options of x4 PCI-E or PCI-X 1.0. bridging between the PCI-E
and PCI-X interfaces enables extra PCI-X slots for I/O expansion, when
the PCI-E interface is used as a host interface to the BCM8603. The
BCM8603 attaches directly to eight SAS or SATA-II disk drives via a
high-performance, integrated 3-Gbit PHY that is capable of driving
long-length backplanes. Hot plug capability is also supported, enabling
drives to be inserted and removed without affecting system operation.
