In BALA VARIYAM, VP, COLLABERA LABS:
Tier IV data centres can be construed as the holy grail of data centre infrastructure technologies. With redundancy at all levels in the data centre infrastructure--right from the dual power server components to the redundant network and HVAC infrastructure, to even a redundant power supply at the data centre itselfTier IV data centres offer almost five nines (99.999 per cent) of availability.
It is not easy to set up a data centre of this level of sophistication. According to me, most of the data centres in India fall under the definition of a Tier III data centre.
KAPIL MEHROTRA, CHIEF MANAGER (IT), APOLLO MUNICH HEALTH INSURANCE COMPANY LTD:
Tier IV data centres are designed for mission critical needs and feature a fail-safe design infrastructure and are deployed in India for high availability, robust IT infrastructure services, managed services, hosted applications, on-demand expansion, and better Internet connectivity.
Some other criteria include: The electricity stays on as redundant transformers keep your servers online. The servers are kept in a climate-controlled environment for maximum performance.
MANUHAAR AGRAWALLA, SYSTEMS MANAGER - CORPORATE IT, EIH LIMITED:
While the capacity of Tier IV data centres is increasing, the utilisation is not going up proportionately. Many organisations are waiting for others to be the early adopters and learn from their experiences. Lack of clarity on the benefits of Tier IV data centres and concerns such as data security and leakage associated with outsourced data centres still prevail.
This should change in the future as the complexity of internal data centres and the need for transaction-based IT costs will force the adoption of these DCs.
