Radian Memory Systems Integrates Zoned Flash SSD With Storage Performance Development Kit

Set of tools and libraries for writing performance, scalable, user-mode storage applications

Radian Memory Systems, Inc. announces a system integration of a zoned flash SSD with SPDK (Storage Performance Development Kit) including associated block level testing.

RMS-350 U.2 Zoned flash SSD

Radian Rms 350 Ssd

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.
