(mes - sage passing technology) architecture. the lsi SAS2208 integrates the latest enhancements in sas and pci express technology. the lsiSAS2208 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 advance - ments in lane and polarity reversal, power management, hot plug support, and msi/msi-x and legacy interrupt generation. the eight-port roc device provides sas and sata data transfer rates of 1.5, lsi ofers the broadest sas product portfolio in the industry with true end-to-end solutions 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, interoperable solution. 3, and 6gb/s per lane and automati - cally negotiates between the speeds. enhanced features are supported such as t-10 data protection model for early detection of and recovery from data corruption, spread spectrum- clocking (ssc) for emi reduction, and data encryption for the protection of confdential data as well as sas 2.1 power management. the lsiSAS2208 is available with encryption and without encryption. the lsiSAS2208 roc integrates a 72-bit, ddr3-1333 sdram interface, hard - ware acceleration engines for raid 5 and raid 6 parity calculations, and the high performance dual core, powerpc 440 risc processor that achieves 1600 dhrystone mips (dmips) resulting in a cost-efective roc ideal for entry and mid-range servers. extending its raid and sas technology leadership, lsi? introduces its fifth generation raid-on-a-chip (roc) lsiSAS2208
