What is zhyperlink?
zHyperLink™ is a new short distance mainframe link technology designed for up to 10x lower latency than zHPF™. zHyperLink is a short distance, mainframe-attached link that provides up to 10 times lower latency than high-performance FICON. z/HyperLink enables much faster read operation with synchronous I/O and low latency access to the databases with fraud detection rules. With the z14 processor, IBM introduced zHyperLink™, a new way to connect processors and storage. zHyperLink I/O is synchronous I/O, which means that the processor will wait until the I/O operation is complete.
