[StorageReview] Supermicro SuperServer with Intel Optane DC Persistent Memory First Look Review

Looking at performance, the Intel persistent memory modules were able to hit a level of performance not yet seen in our lab. Since Intel is more or less the only game in town at the moment with persistent memory we don’t have competitors or older versions to compare to. Instead we compared it to the Intel P4510 2TB NVMe drives as an example of what to expect when leveraging the new technology. In reads the PMMs blew away the NVMe technology with 4K reads being 13.2 million IOPS at only 12.1μs latency and the 64K sequential read hitting 66GB/s at only 57.2μs latency. Random write saw a bit of a limitation of the technology with the persistent memory quickly spiking up to 980K IOPS and roughly 60μs latency before dropping off, much lower than the NVMe drives. 64K writes however saw the persistent memory dominate with at 15.96GB/s at a latency of only 121.8μs. For SQL benchmarks the persistent memory crushed the NVMe drive in SQL (5,095,690 IOPS at a latency of 10.7μs) and SQL 90-10 (1,911,900 IOPS with a latency of 27.1μs). In our Oracle test the persistent memory showed a much higher score in Oracle 90-10 (2,080,543 IOPS with a latency of only 16.9μs) but fell behind in the other two tests from a throughput perspective. Something to note is latency. The highest peak latency for the persistent memory was 103μs and the lowest peak latency was 10.7μs.

That's an insane amount of performance/possible drive space crammed into a 1U case, wow. I guess they are using Windows storage spaces on an HBA card, and hardware raid is just dead. The endurance rating on those Intel DC P4510's is listed at (Up to) 13.88PB, and come in 8TB flavors DROOOOL. Wish they listed the build cost. Thanks for the post, fascinating.

If it's not hot enough to hurt when you touch it, then it's very cool. - TwoCables
