Introduction
The following certification report presents the results of various compatibility and performance tests run on the Intel Optane DC P5800X NVMe Solid State Drive when used in combination with Open-E JovianDSS. A description of the testing methods used during those procedures will also be provided. The resuts obtained from the aforementioned testing and technical specifications were used as the basis for recommendations on specific roles in which to use the device under test (DUT) in Open-E JovianDSS-based systems.

Intel® Optane™ SSD DC P5800X Details
The following table includes the Intel Optane DC P5800X NVMe drive hardware specifications.
| Product name | Intel Optane SSD DC P5800X |
| Model name | SSDPF21Q400GB SSDPF21Q016TB |
| Storage Capacity | 400 GB 800 GB 1.6 TB |
| Form factor | U.2 2.5” |
| Interface | PCIe 4.0 x4, NVMe |
| Technology | 3D XPoint |
| Enhanced Power Loss Data Protection | Yes |
| Security | AES 256 bit encryption |
Testing Process
The functional testing was performed for both the Single node and High Availability non-shared storage cluster configurations. The Intel Optane P5800X was tested in the aspects of high performance, low latencies, writelog for HDD, SSD QLC and TLS NAND data disks. The results look as follows:
The Lowest Latency
As shown in charts 1 and 2, the performed tests have revealed that when used as a writelog, the tested Intel Optane P5800X has shown much greater results in the latency distribution. This result is common for both single node and non-share storage cluster configurations.
Both Intel Optane P5800X 400GB and 800GB have dealt with the latency well. Moreover, the device with 400GB capacity is highly recommended for use as writelog for HDD data disks as it has a sufficient capacity and provides a high endurance rate.
Improved Performance
Open-E also evaluated the performance of the Intel Optane SSD P5800X for read caching. In this test, a setup with an Intel Optane SSD P5800X as a read cache massively outperformed the same setup without a read cache, across all workload tested profiles.

Summary
The Intel Optane P5800X drive was comprehensively tested for full functional compatibility with Open-E JovianDSS. Performance characteristics were also examined in several use cases. Both the Single node and HA cluster environments were taken into consideration. Tests were designed to find any abnormalities in the device, whether used as a read cache or a writelog for Open-E JovianDSS. Its usage showed significant improvement in random IO handling in most cases, especially for loads with large thread number and queue depth. It was also beneficial for throughput in sequential write tests with zpools consisting of HDD drives. Given the results, the tested device has now been added to the Hardware Certification List and granted “Certified by Open-E” status.
