Impact Assessment

Operational Impact: This initiative provides flexibility to colocation participants to optimize their infrastructure by converting existing full racks into High Power Density racks. This allows for better utilization of space and power capacity for members with higher computational requirements.

Affected Parties: Only members and CaaS vendors using NSE’s colocation facility from phase 13 onwards are affected. The initiative does not impact trading operations, market participants, or listed companies.

Financial Impact: Minimal - this is an infrastructure optimization option for existing colocation users.

Disclaimer: Exchange provides colocation facility on best effort basis and is not responsible for any direct/indirect/consequential losses including power failure, air conditioning failure, system failure, connectivity loss, or discontinuation due to legal/regulatory requirements.

Impact Justification

This is an operational enhancement for colocation facility users, allowing existing full rack holders to convert to HPD racks. It affects only members using colocation services and does not impact trading, market structure, or broader market participants.
