At CeBIT, LSI is demonstrating the LSISAS3108 ROC plus MegaRAID 6 technology along with the LSISAS3x48 SAS expander. For those looking to take advantage of 12Gb/s speeds with existing 6Gb/s drive infrastructure, LSI is showcasing DataBolt technology, a bandwidth optimizer performance acceleration feature. DataBolt technology, combined with the extended bandwidth of PCIe 3.0, is designed to deliver double the throughput performance while using today's 6Gb/s SAS or SATA drive solutions.
By doubling the data transfer rate of 6Gb/s SAS solutions, 12Gb/s SAS allows the SAS infrastructure to deliver bandwidth that exceeds that of PCI Express 3.0 with a single host bus adapter (HBA). The improved bandwidth, backed by I/O processing capabilities to maximize link utilization, supports increased scaling of traditional HDDs as well as improved SSD performance. 12Gb/s SAS is also backward compatibile with 3Gb/s and 6Gb/s SAS.
Production-volume shipments of the 12Gb/s SAS ROC and 12Gb/s SAS I/O controller are occurring this month, followed by the availability of 12Gb/s SAS expanders, MegaRAID controllers and HBAs in Q2.
