Lightning Fast I/O via zHyperLink and Db2 for z/OS Exploitation
Akiko Hoshikawa, Db2 Development, IBM
As the size of database and the volume of transactions increase, many of Db2 transactions tend to spend significant amount of wait time in database read and log write I/Os.
zHyperLink is introduced to help reduce b2 transaction latency. zHyperLink is a new short distance mainframe link technology, connecting directly between the CPU and the I/O device. It is designed for low I/O latency to access the disk cache. This article introduces zHyperLink technology and how Db2 applications can take advantage of zHyperLink to reduce the transaction latency.
