raNVMe-IP

raNVMe-IP (Random Access NVMe IP) is the new generation of NVMe-IP series which is intentionally optimized for random access. raNVMe-IP can achieve more than 500K IOPS for random write access on high performance NVMe SSD without CPU intervention. Ideal for the application such as Database Search Application which requires multiple access to NVMe SSD with best performance.
