BT is to trial liquid cooling solutions in a bid to improve energy consumption and efficiency across its networks and IT infrastructure.
The UK's former state-owned telecoms operator said it is trying out several liquid cooling technologies in line with commitments to becoming a net zero business by 2031. The chance that it could bring a 40-50 percent reduction in power needed to cool systems might also make cost savings a factor.
BT announced it will test out liquid cooling for network switches using technology supplied by Iceotope and QFX Series switches from Juniper Networks, which it said are widely used in existing networks.
However, the company is also exploring various alternative cooling techniques in addition to the trials involving Iceotope and Juniper.
These will include full immersion of networking servers in an immersion tank with technology from Immersion4; liquid-cooled cold plate technology for networking equipment supplied by Nexalus; and a system from Airsys where coolant fluid is sprayed directly on the heat emitting components.
