Infiniband Ties Remote Mainframes

Arthur Cole

Massively parallel mainframe clusters spread out over hundreds of kilometers-that's what IBM is angling for with a new breed of long-haul Infiniband technology.


The company recently completed interoperability testing of ADVA's FSP 3000 platform for a new mainframe clustering protocol for the System z operating system designed for Geographically Dispersed Parallel Sysplex (GDPS) environments.


The FSP 3000 was able to maintain a transparent Infiniband link up to 100 km, supporting auto-negotiation between hosts running single data rate and double data rate link speeds. SDR provides a 2.5 Gbps transport link while DDR runs at 5.0 Gbps.


The platform is suitable for a number of high-bandwidth applications, including real-time financial transactions, medical image analysis and university research. It can also be set up as a disaster recovery system for large multi-site enterprises through incorporation of 4 Gbps Fibre Channel and 10 Gbps FC Inter Switch Link (ISL) technologies.
