RAID updates in 2021

New RAID updates in 2021

With the emergence of PCIe drives as a new way of optimizing speeds in the storage stack, many vendors continue to update their RAID cards to include software functionality that enhances the RAID experience. The PCIe bandwidth is much different with the newer RAID cards and as such we have picked out two RAID cards we see being deployed in systems with high-performance metrics:

Broadcom MegaRAID 9560-8i

The MegaRAID 9500 series is the industry’s first PCIe Gen 4.0 RAID adapter family, offering PCIe Gen 4.0 host and storage interfaces. The MegaRAID 9560-8i adapter, based on the SAS3908 high-port count PCIe 4.0 x8 RAID-on-Chip (RoC), delivers twice the performance of previous generations.

NVMe Controller: Flashtec NVMe 3108

The Flashtec® 3rd generation NVMe Controller Family enables the world’s leading enterprises and data centers to realize the highest-performance SSDs by utilizing next-generation NAND technologies

With RAID modes being somewhat similar, the optimizations come at the core RAID card level. RAID 0, 1, 5, 6, 10, 50, 60, JBOD are all subjective to your needs but the way the RAID card interacts with your drives is critical. 

With PCIe 4 making a large emergence, and the 16 GT/s benefits that come with it, the data rates and transfer across some of the newer RAID cards are extremely impressive. With flexible lanes and power usage being an extremely important factor in modern-day deployments, the new RAID cards have incremental benefits for most RAID use cases.
