The primary effort required to complete this integration involved porting the company’s host Block Translation Layer (BTL) for zoned flash from the Linux kernel to SPDK. The firm posted a technical deep dive video that discusses this effort, which includes a comparative, system level analysis between the kernel and SPDK implementations.

The firm’s RMS-350 U.2 Zoned flash SSD that is targeting compliance with the NVMe spec for Zoned Namespaces (ZNS) was utilized in the integration with the fio tester. Configurations included a single SSD and six SSDs in a multi-drive volume.

Pioneered by Intel Corp., the Storage Performance Development Kit (SPDK) provides a set of tools and libraries for writing high performance, scalable, user-mode storage applications.

In addition to the integration and testing with SPDK, the company announces the completion of a JESD218 qualification for a zoned flash SSD. Using a JESD219 compliant overwriting workload, the firm qualified its RMS-350 Zoned flash U.2 SSD under the JESD218 testing requirements.
