muNVMe-IP (Multi User NVMe IP) is designed and optimized for multiple data stream access to single NVMe SSD by multiple users simultaneously.<\/p>\n\n\n\n

RAID0x2 by muNVMe-IP module in this reference design are designed to split one user command to two muNVMe-IPs. The RAID0x2 module is implemented to increase the sequential write\/read performance to 2 times(2X), comparing to the muNVMe-IP reference design.<\/p>\n\n\n\n

muNVMe standard design (1-channel)<\/h2>\n\n\n\n

The first demo of muNVMe-IP shows two users write and read one NVMe SSD at the same time. The performance of each user when two users are run at the same time is about a half of maximum SSD performance. RAID0 system is purposed to increase the performance.<\/p>\n\n\n

muNVMe RAID0 design (2-channel)<\/h2>\n\n\n\n

We show 2-channel RAID0 to increase the write\/read speed to be two times. Two muNVMe-IPs and two SSDs are applied.<\/p>\n\n\n

Main user sends Write command by 32 GB size while Sub user sends Read command by 32 GB size. Both write and read speed are 2399 MB\/s.<\/p>\n\n\n\n

Write\/Write<\/h2>\n\n\n\n

Similarly, we run Write-Write command by two users. Write speed is 2238 MB\/s.<\/p>\n\n\n\n

Performance<\/h2>\n\n\n\n

Let\u2019s see the comparison of the performance result when running standard and 2-Channel RAID0 with muNVMe-IP in several conditions. Performance when using 2-channel RAID0 design increase by 2 times.<\/p>\n\n\n

More performance: 4-ch RAID0<\/h2>\n\n\n\n

If the performance is not enough, we can increase number of channel. 4-channel RAID0 will increase speed by 4 times. 4 muNVMe-IPs and 4 NVMe SSDs are applied in this demo.<\/p>\n\n\n
