(message passing technology) architecture. the sas 3008 integrates the latest enhancements in sas and pci express technology. the sas 3008 supports 8 pcie? lanes and complies with the pci express 3.0 specifcation that extends the pcie data rates up to 8.0 gt/s per lane, and is backwards compatible to the 5.0/2.5 gt/s data rate supported by pcie 2.x., 1.x. it also incorporates enhancements such as end-to- end crc (ecrc) with advanced error reporting (aer) and the latest advancements in lane and polarity reversal, power management, hot plug support, and msi/ msi-x and legacy interrupt generation. the eight-port controller device provides sas data transfer rates of 12, 6, and 3 gb/s per lane, and sata at 6 and 3 gb/s data transfer rates per lane. the device automatically negotiates between the speeds. enhanced features are supported such as t-10 data protection model for early detection of and recovery from data corruption, and spread spectrum clocking (ssc) for emi reduction. additional features include databolt? technology allowing users to take advantage of 12 gb/s speeds while utilizing existing 6 gb/s drives and backplanes. the sas 3008 is ideal for the host or drive side connect for external storage controllers requiring a sas/sata interface. the sas 3008 can support up to 1,000 devices and 8,000 outstanding ios without external ram and can achieve over 1 million ios per second. pci express ? to 8-port 12 gb/s sas+sata controller SAS3008
