FAQ

Data questions, answered.

Scope, timelines, security posture and delivery models — the details buyers and technical leads ask us before signing.

Ask a specific question
What's in scope for data centre engagements?

Site selection, high-density rack and power design (up to 130kW/rack), liquid and rear-door heat-exchanger cooling, structured cabling, DCIM, and ongoing facilities operations for colo, edge and on-prem environments.

Typical delivery timelines?

Design and BoM: 3–5 weeks. Retrofit of an existing hall for AI density: 8–16 weeks. New-build fit-out: 4–9 months depending on power and cooling procurement lead times.

How do you address physical and operational security?

Layered access control, CCTV with 90-day retention, tamper-evident cabinets, dual-custody procedures, and full evidence packs for ISO 27001, PCI DSS and Tier III+ Uptime Institute audits.

Do you offer ongoing facilities management?

Yes — 24/7 remote hands, preventative maintenance, capacity and thermal analytics, and quarterly resilience testing under a fixed monthly SLA.
