Data Center Technologies

24G SAS technology is more than a speed upgrade for the Serial Attached SCSI (SAS) interface. It implements a major overhaul of the interface, including the use of 128b/150b encoding, with 20-bit forward error correction, as well as a number of other new features and enhancements. The new SPL packet encoding scheme also introduces the opportunity for new bandwidth aggregation techniques. It preserves the existing SAS value proposition of reliability, availability, scalability, flexibility and low total cost of ownership. In addition, SAS-4 technology offers backwards compatibility with previous-generation SAS implementations, which means that older drives will be compatible with newer storage controller and SAS expander products. 
 

Innovations in memory infrastructure are poised to significantly improve the performance and cost effectiveness of mainstream data center applications. Memory infrastructure innovation is occurring along two vectors: near-memory innovations and far-memory innovations. Near-memory innovation improves business application performance by driving up the number of SoC and CPU memory channels and improving the bandwidth of individual memory channels while enabling innovative and lower-cost memory technologies to be connected seamlessly to the SoC. Far-memory innovation delivers shareable pools of memory resources that both drive up aggregate system memory utilization (and therefore drive down cost) and improve application performance as arrays of SoC devices can simultaneously operate on the shared memory pool. Memory infrastructure encompasses a broad range of new and emerging media types and interface technologies.
