Piyush Somani shares his vision on using alternative cooling methods and renewable energy
Data storage cos in a sweat over need to stay cool
A number of data centres — where digital data is stored — are experiencing a sharp spike in operational costs as they endeavour to stay cool amid soaring temperatures across most of western and northern India.
Greater need for power and cooling equipment has resulted in costs rising by nearly a fifth at these centres, several of which are located in Haryana’s Manesar, New Delhi and Noida.
Top storage firms such as Yotta Data Services and CtrlS Datacenters said they are using alternative cooling solutions such as liquid and adiabatic cooling, improving efficiency of power consumption and using techniques such as proactive and accurate microclimate analysis.
Others like ESDS Software Solutions estimate that power cost alone has risen by 10-12% as patchy supply from power grids is forcing them to seek alternative infrastructure to meet cooling needs.
“One of the critical issues we are facing is the inconsistent availability of grid power,” said Piyush Somani, chairman, ESDS Software Solutions.
Erratic Electricity Supply an Issue
“All over India, we are witnessing an unstable power supply from the grid, and this needs to be addressed on an immediate basis,”
said Somani. With the relentless heat straining the installed cooling systems, Somani estimates his company is facing “15-20% rise in operational expenses, as electricity expenses have risen by 10-12% due to the higher need for cooling”.
India’s capital is sweltering with an acute heatwave which took temperatures to a record high of 52.9 degree Celsius on May 29.
In the last week of May, 37 cities in the country recorded temperatures above 45 degrees, according to data from the weather department.
“High temperatures are impacting data centres that are located more in North India,” said Rajiv Ranjan, associate research director, cloud & AI at research firm IDC India. “Although, 70% of supply capacity is concentrated in Mumbai, Chennai and Bengaluru, there are some data centres in Noida, Manesar and New Delhi hosted by companies like Sify Technologies, CtrlS, Nxtra Data and ST Telemedia.” Data centres using advanced liquid cooling will certainly incur marginally higher costs in the next coming months, he said.
ALTERNATIVE MEASURES
Despite power outages becoming common, data centres are ensuring there is no downtime in their operations with nearly four levels of redundancy support and emergency preparedness built in.
ESDS is using alternative methods such as liquid cooling and free cooling systems, which can significantly reduce energy usage and dependence on conventional air conditioning systems and has also tapped into renewable energy sources such as solar and wind to reduce its reliance on the state grid.
