Abstract
Using NVMe drives in a centralized manner introduces the need for high availability. Without it, a simple failure in the NVMe enclosure will result in loss of access to a big group of disks. Loss of a single NVMe disk will impact all hosts mapped to this disk. We will review the state of the industry in approaching these problems, the challenges in performing HA and RAID at the speeds and latency of NVMe, and introduce new products in this space.
