Case Study: Internet Initiative Japan (IIJ) builds a high-performance object store with OpenIO SDS

IIJ Chooses OpenIO SDS to Build a High-Performance Object Store for their Email Service for Secure Sensitive Organizations

Internet Initiative Japan (IIJ), an enterprise-grade cloud service provider in Tokyo serving more than 11,000 customers, needed a highly secure, highly available storage backend for its mission-critical email and MX services. To support demanding SLAs, disaster recovery requirements, and rapid growth, IIJ looked for a scalable object storage platform with strong performance and full code visibility; it chose OpenIO SDS.

OpenIO implemented an all-flash, two-datacenter object store based on OpenIO SDS, using its scale-out architecture, no-rebalancing design, and asynchronous replication for disaster recovery. The result was a high-performance storage system capable of handling peaks of 5,500 indexed emails per second, supporting 2 million managed mailboxes and more than 1,400 MX service customers, while allowing IIJ to add capacity without downtime and improve RPO/RTO in the event of disasters.
