What is the next-generation data center that Rakuten network engineers aim for? -Mr. Hiroki Fujii-

As a keynote speech this time, Mr. Hiroki Fujii, a network engineer at Rakuten Group, Inc., talked about what Rakuten en's idea of next-generation data centers should be Rakuten He also introduced what kind of issues he has while providing various services and the efforts of "KAIZEN activities" to address those issues.

Currently, more than 70 services are deployed in 30 countries around the world, each of which has a network architecture that handles different types of traffic, and please explain how each infrastructure supports each other. I was. Based on actual examples, he explained in an easy-to-understand manner the details of specific KAIZEN activities to pursue simpler, more standardized, and more stable infrastructure that is complicatedly intertwined.

Optical Network Strategy Emphasizing Cost Performance - Mr. Hiromichi Higashimatsu -

Mr. Higashimatsu introduced the operation results of the third-party transceiver that was adopted to realize the cost reduction of the network infrastructure. We would like you to tell us about the results of operating about 10,000 of them, as well as the valuable experiences of companies that actually operate them, such as the attitude and precautions when introducing third-party transceivers. I was. Both cost and quality must be considered when building infrastructure, so it was very helpful.

From NVMe to NVMe over Fabric -The True Power of NVMe Unleashed by EBOF-Shiro Yada-

Currently, the shift from conventional HDDs to SSDs, which emphasize speed, is rapidly spreading in the field of storage systems, and the interface is also evolving to faster NVMe. However, there are many bottlenecks in the whole system, and it has not yet been able to demonstrate its true power. In the lecture, he explained the EBOF concept that fully demonstrates the capabilities of NVMe advocated by Marvell. It is a must-see for the technology that makes it possible to achieve low latency, which is indispensable in the world where 5G is about to take over.

Latest Trends in Optical Transceivers in the Data Center Market ～Mr. Yosuke Takahashi～

Currently, 100G networks are becoming the main network in data centers, and he explained the market trends and future technology trends for 400G and even 800G in the future. As a trend in the world, the transition from 100G to 400G is already progressing, and there are still some uncertainties regarding future standards. Finisar participates in various standardization organizations as a key member, so I think the trends that Finisar thinks will be very helpful in understanding future trends.
