IT TODAY An Unforgettable MEMORY INNOVATION Flash Express integrates secure, high-performance storage within System z F Peter Svwed is a senior engineer and IBM Master Inventor in the Systems and Technology Group. Edward W. Chencinski is a senior technical staff member and chief engineer of an I/O subsystem development team within IBM Systems and Technology Group. Called Flash Express, this feature is implemented with PCI Express (PCIe) adapters containing SSDs configured in RAID 10 arrays across cable-connected pairs in I/O expansion drawers. The initial exploitation of Flash Express is as an extension to main memory in z/OS* where it's integrated within the memory hierarchy and administered by the z/OS memory manager to provide increased system availability and resiliency during paging-intensive events. 14 // JANUARY/FEBRUARY 2014 Benefits of Flash Express Server installations are being pressured to deliver increasingly higher levels of availability in nearly every industry-especially finance, banking and healthcare. With Flash Express, the system can reduce workload and response-time delays caused by increased memory pressure during periods of peak demand, transitions between workloads or diagnostic collection. For example, when transitioning from a transactional workload during a prime shift to a batch workload, and then back again during the next prime shift, response-time delays can occur. The system can reduce these delays by using Flash Express when data for the prime shift must be transferred from auxiliary storage into main memory. Flash can also help when the system must transfer data into main memory as part of a diagnostic dump. The ILLUSTRATION BY HARRY CAMPBELL or the first time, flash storage has been integrated into IBM System z* servers. This new function brings an enhanced client experience on enterprise applications by providing additional auxiliary storage with higher performance than external disks.
