Improve Application Performance with Open Cache Acceleration Software (Open CAS)

Today's data centers are held back by storage I/O that cannot keep up with ever-increasing demand, preventing systems from reaching their full performance potential. Traditional solutions, such as increasing storage, servers, or memory, add huge expense and complexity.

Open Cache Acceleration Software (Open CAS), combined with high-performance Solid State Drives (SSDs), increases data center performance via intelligent caching rather than extreme spending. Open CAS interoperates with server memory to create a multilevel cache that optimizes the use of system memory and automatically determines the best cache level for active data, allowing applications to perform even faster than running fully on flash/SSDs.1

Open CAS is a project derived from the product Intel® Cache Acceleration Software (Intel® CAS). For Linux use cases, all usage has transition to Open CAS, but the data and use cases proven using Intel® CAS are still relevant. Intel still provides Intel® CAS for Windows.

Accelerate Your Scale-Out Storage Performance

Yahoo needed a faster, lower cost way to process hot data for 1 billion users a day. They got it by deploying Intel® Cache Acceleration Software (CAS) 3.0 on the Intel® SSD data center family for PCIe* in their existing Ceph* environment.

Experience Open CAS

Whether you are using VMs or dedicated servers, you will quickly see how Open CAS server-side caching software plus any flash device (SAS, SATA, or PCIe*) can accelerate your I/O-bound business applications relaying on slower SAN or direct attached back-end storage.
