NVMe SSD provides very fast storage access, its performance surpasses SATA SSDs or traditional HDDs significantly. As the SSD technology moves on, a single NVMe SSD can be overkill for most computing server. However, sharing the resource among multiple servers often limits SSD’s performance as the networking creates I/O bottleneck. As a result, NVMe SR-IOV was introduced to solve this issue. It is more difficult to solve multi-server interconnection bottleneck, but we could leverage [...]

We have discussed some benefits of multi-host NVMe SR-IOV, or multi-root SR-IOV (MR-IOV) last time, the solution aims to improve SSD performance under virtual environments while ensuring high utilization and flexibility for the storage resources. In this blog, let’s take a closer look at the performance aspect, see how exactly our proposed NVMe MR-IOV delivers high-performance in virtual environments. Interface: The Most common interface for disks today is probably SATA, but NVMe SSDs [...]
