Graid Technology

, which Intel describes as Achieving Optimal Performance & Endurance on Coarse-grained Indirection Unit SSDs. This allows the SSD vendor to significantly reduce the amount of DRAM on the SSD and reduce the cost per gigabyte of the drives, allowing for even better TCO. Good performance can be achieved by optimizing the workload to have higher block size or more sequential pattern for writes; reads are not impacted. The Solidigm and Graid Technology Inc. teams have identified some potential software improvements in the future to fully take advantage of SSDs like the D5-P5316 write performance and workload patterns.ConclusionCan we have data protection, high-performance, AND high-capacity? Yes. No longer are we forced to choose between reliability and performance. As demonstrated in this case study, the SupremeRAID™ solution delivers both.With massive capacities of up to 368TB raw in a 1U server or 737TB raw in a standard 2U server leveraging high capacity QLC based NVMe drives, SupremeRAID™ delivers outstanding RAID5 performance, great rebuild times and high durability with a full

better durability at RAID6 than Linux software RAID.1U Server Density LeadershipWith U.2 we are able to reach 184TB raw with 15.36TB and 368TB raw with 30.72TB capacity in a standard Supermicro 1U server!1U Performance LeadershipRAID 0 with 12 drivesWe see RAID 0 scaling almost perfectly on reads, 84GB/s is 7GB/s per drive. The RAID 0 write performance hits 14GB/s, which is very good, but lower than the theoretical capability on these devices. During the testing the team identified potential software improvements on these QLC devices to achieve maximum performance, which you can read about in the

The majority of SSDs in our data set consume PE cycles at a very slow rate. Our projections indicate that the vast majority of the population (~95%) could move toward QLC without wearing out prematurely.
