SANBlaze Enhances ZNS Test Suite for NVMe Storage Devices

SANBlaze Technology, Inc. enhanced its ZNS test suite for NVMe storage devices.

Working with one of the industry ZNS SSD vendors, the company has doubled its ZNS tests from 105 to over 200, and then added more than 200 negative test cases as well to make it the only ZNS testing vendor to provide all-inclusive ZNS testing.

“ Operating under the Certified by SANBlaze test framework, our enhanced ZNS suite provides compliance, functional and ‘negative’ test cases ensuring specification compliance, functionality and completeness of your ZNS implementation, or verifies the ZNS functionality of your NVMe drive vendor’s ZNS implementation,” said Vince Asbridge, president.

What is ZNS for NVMe?
Zoned Namespaces (ZNS) was established by the NVMe Technical Work Group to improve the performance of SSDs in applications for hyper-scalers, AFA vendors, and large storage system vendors.

This technology allows for dividing the physical storage media into logical zones governed by the NVMe ZNS spec and is a critical part of the recently ratified NVMe V2.0 spec. It allows optimization of the host’s file system to take advantage of NVMe storage behavior within defined zones and therefore allows optimization of the host file systems to take advantage of the predictability of the IO subsystem matching the specific needs of the given file system.

File systems currently supporting ZNS include F2FS, Btrfs, ZFS, and XFS starting with the Linux V4.9 Kernel, and is being driven by major NVMe datacenter customers due to the optimization for archival storage and IO predictability.

Certified by SANBlaze ZNS solution
Combined with the Certified by SANBlaze test system, the enhanced ZNS qualification test suite contributes to the nearly 1,000 test and negative test cases, providing a ‘One Button’ built-in qualification suite. It presents a detailed pass/fail report for each test cycle for easy management of results.
