Thereâ€™s no need to wait for higher speed. Server builders can take advantage of 12Gb/s SAS now. And this is even as HDD and SSD makers continue to tweak, tune and otherwise prepare their 12Gb/s SAS products for market. The next generation of 12Gb/s SAS without supporting drives? What gives?
Itâ€™s simple. LSI is already producing 12Gb/s ROC and IOC solutions, meaning that customers can take advantage of 12Gb/s SAS performance today with currently shipping systems and storage.Â As for the numbers, LSI 12Gb/s SAS enables performance increases of up to 45% in throughput and up to 58% in IOPS when compared to 6Gb/s SAS.
True, 12Gb/s SAS isnâ€™t a Big Bang Disruption in storage systems; rather itâ€™s an evolutionary change, but a big step forward.Â It may not be clear why it matters so much, so I want to briefly explain.Â In latest generation PCIe 3 systems, 6Gb/s SAS is the bottleneck that prevents systems from achieving full PCIe 3 throughput of 6,400 MB/s.
With 12Gb/s SAS, customers will be able to take full advantage of the performance of PCIe 3 systems.Â Earlier this month at CeBIT computer expo in Hanover, Germany, we announced that we are the first to ship production-level 12Gb/s SAS ROC (RAID on Chip) and IOC (I/O Controllers) to OEM customers.Â This convergence of new technologies and the expansion of existing capabilities create significant improvements for datacenters of all kinds.
At CeBIT, we demonstrated our 12Gb/s SAS solutions with the unique DataBoltTM feature and how, with DataBolt, Â systems with 6Gb/s SAS HDDs can achieve 12Gb/s SAS performance.
DataBolt uses bandwidth aggregation to create throughput performance acceleration. Â Most importantly, customers donâ€™t have to wait for the next inflection in drive design to get the highest possible performance and connectivity.
