(mes - sage passing technology) architecture. the lsiSAS2308 integrates the latest enhancements in sas and pci express technology. the lsiSAS2308 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 single root i/o virtualization (sr-iov) with 16 virtual functions, 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 and sata data transfer rates of 1.5, 3, and 6gb/s per lane and automatically negotiates between the speeds. enhanced features are lsi ofers the broadest sas product portfolio in the industry with true end-to-end solu - tions controllers, expanders, sas to sata bridge products, rocs, host bus adapters, raid solutions, and external storage. lsis proven sas core has completed extensive stress and interoperability testing resulting in the industrys most robust, interoper - able solution. supported such as t-10 data protec - tion model for early detection of and recovery from data corruption, and spread spectrum clocking (ssc) for emi reduction. the lsiSAS2308 is ideal for the host or drive side connect for external storage controllers requiring a sas/sata inter - face. the lsiSAS2308 can support 1,000 devices and 10,000 outstanding ios without external ram and can achieve 600,000 ios per second. the lsiSAS2308 ofered with lsis integrated raid (ir) feature is a low cost, high performance raid solution designed for blade, entry and mid- range servers that require redundancy and high availability but where a full extending its raid and sas technology leadership, lsi? introduces its third generation of sas/sata controllers lsiSAS2308
