Case Study: Universitätsklinikum (University Clinic) Leipzig data center achieves sub‑millisecond SAP response and avoids costly storage upgrades with SanDisk Fusion ioMemory PCIe

University Clinic Leipzig Speeds Sap Application Response With Fusion Iomemory Pcie Solutions

Universitätsklinikum Leipzig, a full‑service university hospital, faced poor response times after virtualizing its data center: its SAN could not handle the load from a 600 GB SAP database with up to 2,000 concurrent users, leaving no reserve capacity and causing long job runtimes. The IT team sought a server‑side caching approach to relieve the strained storage system without a costly SAN replacement.

The hospital deployed Fusion ioMemory PX600 PCIe accelerators (5.2 TB aggregate) and 400 GB SSDs in its FUJITSU servers with a PernixData caching layer, shifting roughly 90% of ~5,000 peak IOPS onto flash. Response times dropped to under 1 ms, the solution has run reliably for over a year, allowed per‑VM read/write acceleration, avoided expensive storage upgrades, and was extended to other CPU‑intensive apps like SQL Server and SharePoint.
