Here's a summary of our talk/demo:

Talk: SPDK’s OCSSD FTLs on Zao Platform to Solve Cloud’s Noisy Neighbor Problem

Since the SPDK community introduced Open-Channel SSD (OCSSD) FTL bdev in January 2019, Circuit Blvd and Marvell have been jointly evaluating it on Marvell's Zao SSD SoC platform. We will first present Zao platform technical details including OCSSD SDK features. We measured various performance metrics from the initial prototype in comparison with the standard NVMe devices. In conclusion, we will demonstrate how SPDK OCSSDs can solve the noisy neighbor problem in multi-tenant environments.

Demo: SPDK Driven OCSSD Comparison (Isolation vs Non-Isolation)

Live-demo on Xeon server with 2 Zao OCSSDs. 3 read tenants and 1 write tenant are generating workloads to 2 OCSSD devices (A and B). Device A is configured for channel isolation while Device B is not configured for channel isolation.
