The PCIe® Gen 4 and Gen 5 specifications represent exciting new advancements in input/output (I/O) technology and are expected to be widely adopted across a wide range of data center and automotive Advanced Driver Assistance Systems (ADAS) designs. This includes processing and peripheral devices such as Graphics Processing Units (GPUs), Central Processing Units (CPUs), Network Interface Cards (NICs), NVM Express® (NVMe®) Solid State Drives (SSDs), storage controllers, automotive cameras and infotainment systems. Applications such as Artificial Intelligence (AI) and Machine Learning, as well as traditional enterprise workloads utilizing networking, storage and offload processors, can all benefit from the increased bandwidth of next-generation PCIe systems.
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.
End users continue to rely on RAID for server-level primary storage protection. Crucial applications of RAID include cost-effective protection from drive failure for boot volumes, primary data storage and database applications. Due to their high cost, NVM Express™ (NVMe™) device use has previously been confined to high-performance applications However, as these costs have started to decrease, NVMe drives are starting to be adopted for traditional primary storage use in enterprise data centers. NVMe SSD volumes are quickly becoming the preferred storage media for capacities <4 TB. The latest developments mean that RAID for NVMe SSDs will be a mandatory offering in the data center.
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.
