Why ficon

The Open Systems Adapter functions as a network controller that supports many networking transport protocols, making it a powerful helper for this efficient approach to data movement. To achieve better overall performance, the data is captured well before tape handling, thus avoiding the overhead of tape management, tape mounts, etc. Rather than relying on serialized data movement, this approach breaks apart large datasets and sends them across the wire in simultaneous chunks, while also pushing multiple datasets at a time.

Data can be compressed prior to leaving the mainframe and beginning its journey, reducing the amount of data that would otherwise be written. Dataset recalls and restores are also compressed and use multiple streams to ensure quick recovery of data from the cloud.

Having the ability to write multiple streams further increases throughput and reduces latency issues. In addition, compression on the mainframe side dramatically reduces the amount of data sent over the wire. This approach delivers mainframe data to cloud storage, including all dataset types and historical data, in a quick and efficient manner. And this approach can also transform mainframe data into standard open formats that can be ingested by BI and Analytics off of the mainframe itself, with a key difference.

Fibre Channel captures these characteristics in the FC-SB architecture and the FICON transport defines a system with superior abilities to share IO across multiple systems, maintain application performance over distance, insure data integrity and security, and provide optimal protocol efficiency.

Patty Driever, IBM Corporation, Howard Johnson, Broadcom Corporation Since its introduction in , Fibre Channel has become well recognized as the leading technology choice for storage attachment — it delivers superior scale, reliability, dependability and manageability.

With Fibre Channel as the underlying transport, work began in the INCITS T11 standards body to define a protocol mapping that addressed the particular needs of the mainframe: Predictable and superior performance even with increased distances between the server and storage devices, and Enhanced reliability, availability, scalability and security, beyond what is provided by Fibre Channel natively to all ULPs.

Improve Performance and Flexibility IBM mainframes have been the workhorses of the computing world for almost 50 years and many large organizations still entrust IBM System z servers with their most mission-critical and demanding applications.

The MDS Mainframe package includes a number of features, including: Support for Virtual SANs VSANs This helps to enable workload isolation, division of management, and control of fault-domains all within a single platform, with superior reliability and scalability.
