Huawei Technologies Co Ltd, a provider of next-generation telecomms network solutions, announced on Thursday (25 September) that its OptiX DWDM (Dense Wavelength Division Multiplexer) products suite has successfully completed interoperability testing and qualification for information technology company IBM GDPS (Geographically Dispersed Parallel Sysplex) and STP (Server Time Protocol) system environments.

According to the company, Huawei OptiX products are now certified to extend the reach of data centres running GDPS/STP applications by up to 200km with IBM System z mainframes.

GDPS is understood to be a computing environment that provides for a set of disaster recovery and continuous availability solutions, particularly suited for complex multi-site networks. To reduce any impairment resulting from planned and unplanned outages, many large enterprises are implementing system and storage redundancy with high availability, business assurance and disaster recovery capabilities.

The Huawei products support both traditional ETR (External Time Reference) CLO (Control Link Oscillator) and the latest STP systems, reducing the number of wavelengths required and extending the transmission distance. In addition, they support all typical storage protocol interfaces including ESCON, GbE, ISC-3 (STP), ETR/CLO, FC/FICON 1G/2G/4G.

Compared with traditional systems where one wavelength is occupied by one channel of ISC (Inter-System Channel) service, OptiX DWDM solution enables one wavelength to transport up to eight channels of ISC services or eight channels of intermixed services including ISC and FC/FICON/GbE Services based on TDM (Time-Division Multiplexing) technologies, the company said.

No pricing details were disclosed.
