muNVMe-IP

muNVMe-IP (Multi User NVMe IP) is designed and optimized for multiple data stream access to single NVMe SSD by multiple users simultaneously. muNVMe-IP can achieve close to SSD's maximum possible throughput for both mixed read/write and same direction access. This IP is recommended for the application that requires high performance & multiple data streaming or sequential access over single NVMe SSD by pure hardware logic without CPU/OS. Customization to increase the number of users is possible upon customer's requirements.
