As we said in part 1 of this blog, IBM issued a Statement of Direction for zHyperLink™, on January 10th , for the first new mainframe I/O Channel link technology since FICON®.
zHyperLink is a latest technology that can be installed on existing IBM DS8880 Storage Systems®. The hardware capability is already included in the DS8880 R8.2 Storage Systems and is intended to speed up DB2® for z/OS transaction processing and improve active log throughput.
IBM storage has delivered on a cadence of new I/O technologies over the last few years to address the need for improved I/O latency for storage. These technologies include:
As new technologies are deployed in transport, memory, and devices new opportunities are created for innovative system architectures to deliver value to IBM mainframe clients.
The IBM zHyperLink™ Technology
The IBM zHyperLink™ technology is a new mainframe attach link. It is the result of collaboration between DB2 for z/OS®, the z/OS operating System, z Systems processors, and DS8880 storage to deliver extreme low latency I/O access for DB2 for z/OS transaction processing and improve active log throughput.
The DS8880 R8.2 (models 984, 985, 986, and 988) available in 4Q2016, contains the hardware intended to support this technology. IBM also intends that DS8880 models that shipped prior to December 2016 get concurrently field upgradeable for zHyperLinks.
The zHyperLink is a point-to-point optical connection between the mainframe and storage. The link length is limited to 150 meters, which is the same distance supported by the z Systems short distance coupling technology.
The client benefits of IBM zHyperLink™ technology are:
The IBM DS8880 is designed from the casters up for extensibility, client invest protection, and availability. The IBM zHyperLink™ technology is intended to make z/OS a more attractive platform for deploying new workloads, for growing heritage workloads with improved scalability and leveraging reuse of existing storage assets. Issuing the statement of direction allows clients to plan their machine rooms, disaster recovery strategy, and application deployment choices in anticipation of this new technology.
