Kalgoorlie Consolidated Gold Mines (KCGM), located in the remote mining town of Kalgoorlie in Western Australia, has replaced its data network with a network from Nortel to improve security and reliability.
KCGM manages and operates the ‘Super Pit’, producing up to 850,000 ounces of gold every year.
At 3.2 kilometres in length, 1.4 kilometres in width and more than 450 metres deep, it is also the biggest open pit gold mine in Australia.
Due to it’s remoteness from metropolitan centres, KCGM demanded a network that would service sensitive communication equipment against failure.
According to KCGM’s senior IS coordinator Shaun Fessey, the company required a fail-safe computer network because replacement parts can often take several days to source.
“We approached Nortel for its unique network architecture, which prevents single points of equipment failure from bringing down the network, and for its dedicated security features that allow us to block individual access to the network and manage network access through user profiles, an important precaution in a large, remote site,” he said.
The Nortel solution, being sold and implemented by Nortel Power channel partner WJ Moncrieff, includes a combination of Ethernet Routing Switch (ERS) 5530s for the network core and ERS 5520 switches at the network edge.
The switches feature Split Multi Link Trunking (SMLT) architecture, which eliminates single points of failure on the network by giving each switch multiple paths to route network traffic.
The network also features a Secure Network Access (SNA) technology that manages network access based on individual user profiles as opposed to physical devices, which prevents rogue devices from accessing the network without the proper user authentication.
The data network switches have been validated by two independent third-party reports from InfoTech and the Tolly Group, to be resilient to failure.
