This Japanese social networking pioneer deploys ioMemory PCIe cards to consolidate servers, improve service, and reduce maintenance and power costs.
mixi, Inc. (pronounced “Mikushi”) is Japan’s largest social networking site, with over 26 million users. Operating since 2004, it has pioneered the social network space in Japan.
mixi had been hosting its user space on a conventional, disk-based MySQL database system. However, it needed an agile and flexible infrastructure to manage its large and continually increasing user base. Application Operation Group Chief, Yoshitaka Yabusaki, and his team found they could not scale performance without increasing cost and complexity.
mixi needed a solution to do the following:
Yoshitaka said, “We urgently needed to consolidate our database farms to reduce our maintenance burden, as well as our operating costs.”
Yoshitaka had heard from many sources that Fusion ioMemory’s read and write performance was the best on the market, so he contacted Tokyo Electronic Devices (TED) to place an order. The results were better than he expected.
mixi’s primary objective was to ensure the reliable, best-in-class service its users had come to expect. As mixi’s disk-based system grew, Yoshitaka’s team faced the key challenge of deploying necessary database updates.
“Running the same database version across all live servers is essential for a trouble- free environment,” said Yoshitaka, “but it was not possible for us to update database software and applications simultaneously across hundreds of servers. This was a grave concern to us.”
The answer: move mixi’s distributed, scaled databases from hundreds of local hard disks onto ioDrive® devices. This increased the workload each server could handle so much that Yoshitaka’s team was able to slash the number of servers they had to maintain by more than 10 to 1.
Yoshitaka said, “We reduced the number of servers in our system to 1/10th, from several hundred to a few dozen. Even with such significant consolidation, the overall database system speed increased.”
Reducing Hardware Footprint and Operating Costs
In order to achieve this level of server consolidation, Yoshitaka’s team took advantage of Fusion ioMemory’s ability to fully utilize server CPUs and upgraded to more powerful servers. The ROI on this investment was significant.
Yoshitaka said, “We reduced our data center footprint to 1/4th the size of the previous system, greatly reducing our floor space and system administration costs. This also reduced our database layer’s power consumption by 80%—something that has become much more important with the rolling blackouts of post-Fukushima Japan and the mandate to eliminate nuclear power plants in 2012. We are now prepared for these events.”
A Simple and Easy to Maintain System
Eliminating 90 percent of its servers greatly reduced Yoshitaka’s team’s system administration tasks and made it much easier to install needed updates.
“We had been putting off installing some large patches because we couldn’t guess how long they might take to install,” said Yoshitaka. “We can now update software much faster, more frequently, and without disrupting our customers’ experience. We are now running the latest, most stable software versions. Daily maintenance tasks, including backups, also run much faster.”

Reduced number of servers 10 to 1, upgrading each as follows:
Implementing Fusion ioMemory gave mixi the following benefits:
Yoshitaka is thrilled with mixi’s new system and told us, “The total cost of ownership of the ioDrive devices, including the operating costs, was lower than other solutions. Reliability was also extremely important to us. With SanDisk’s proven reliability and wide US OEM and vendor support, we felt we could trust our mission-critical databases to SanDisk.”
