Case Study: Ikyu.com achieves sub-2-second search response and improved availability with SanDisk Fusion ioMemory PCIe cards

Ikyu Implements Fusion Iomemory™ Pcie Cards To Speed Up Search Response And Reservations Of Luxurious Hotels

Ikyu Corporation, operator of the luxury hotel and restaurant reservation site ikyu.com, serves millions of users and faced growing performance issues: searches with broad criteria and traffic spikes regularly pushed response times above their <2‑second target and exposed storage I/O as the system bottleneck. Ensuring fast, reliable search and booking performance without large additional server counts became a business priority.

Ikyu migrated from HDDs to Fusion ioMemory PCIe flash (ioDrive2 and PX600), dramatically increasing storage IOPS and read/write speed. As a result, searches consistently meet the <2‑second target, booking and batch processes run faster, availability and fault tolerance improved, and overall server efficiency and IT investment were optimized — with stable operation sustained for years.
