Design, build, migrate, and operate Tier III aligned data centers
- Tier III Aligned
- Hybrid & Multi-Cloud Ready
- Security & Compliance Built-In
ZMJ designs, builds, migrates, and operates Tier III-aligned data centers that are secure, efficient, and compliant from day one. We combine facility engineering, resilient power architectures, carrier diversity, and managed operations with strong security and data governance aligned to global standards. The result is predictable uptime, lower operating cost, clean audits, and faster delivery for mission-critical workloads in banking, public sector, energy, health, media, and enterprise.
Predictable uptime
Lower operating cost per kW
Clean audits and faster delivery
What we deliver
- Site and risk
Location study, soil and flood analysis, physical threat model, power feasibility with utility and Independent Power Producer options, noise and emissions plan, and future expansion envelope. - Facility architecture
Tier III aligned topology with N plus 1 power and cooling, dual power paths, hot or cold aisle containment, raised floor or slab design, structured cabling, and DCIM-ready sensor grids. - Mechanical and electrical
High efficiency UPS, precision cooling, containment design, generator sizing and runtime plan, ATS and switchgear, earthing and lightning protection, fire detection and clean agent suppression. - Physical security
Layered perimeters, mantraps, biometric access, CCTV with retention, escorted access workflows, contractor controls, and visitor logging.
- Workload discovery
Application mapping, RTO and RPO classification, performance baselines, and interdependency charts. - Migration waves
Physical to virtual moves, cross hypervisor, cross OS and database, container onboarding, and rollback runbooks with business acceptance tests. - Hybrid connectivity
Private interconnects or VPN to public cloud, shared services for backup, archive, analytics, and burst capacity. - Resilience overlay
Disaster recovery strategy, DR drills, and business continuity plans tied to application tiers.
- 24 by 7 operations
NOC and service desk, incident and change management, vendor coordination, spare strategy, and on-call engineering. - Capacity and performance
Utilization tracking, trend forecasting, patch and configuration management, and continuous improvement cycles. - Backup and restore
Policy design, immutable storage options, periodic recovery tests, and air gap designs for ransomware resilience. - Energy efficiency
PUE tracking and improvement plan, containment audits, and seasonal tuning to reduce power cost per kW.
- Security operations
Managed firewall, WAF, endpoint detection and response, SIEM, vulnerability scanning, and incident response with post-incident review. - Compliance support
Alignment with ISO 27001 controls, PCI DSS ready, where cardholder data is processed, audit evidence packs, and log retention policy. Regional privacy laws are accommodated through purpose-binding, consent capture, and data residency options. - Governance
Data Protection Officer function, DPIA templates, data flow mapping, vendor risk management, and role-based access with MFA and privileged session recording.
Why ZMJ?
Region ready
Designs that respect local power quality, fuel logistics, and last-mile realities, with in-country or in-region hosting and data residency by default.
Transparent outcomes
Clear SLAs, KPIs, and reporting. You see the uptime, response times, PUE, and patch cadence in black and white.
Faster time to value
Reference designs, standard runbooks, and proven migration patterns shorten time to first workload and reduce risk.
Hybrid without friction
Private infrastructure with clean paths to public cloud for burst, backup, and analytics, observable in one place.
99.98 percent monthly uptime target for critical systems measured by DCIM and synthetic probes.
RTO under 4 hours for priority applications where architecture supports it. RPO as low as 15 minutes with synchronous or near synchronous replication.
PUE target range 1.6 to 1.8, depending on climate, load, and containment.
Critical incident acknowledgement in 15 minutes and action underway within 60 minutes. Quarterly external vulnerability scans and annual independent security assessment.
DPIA completed before going live. Access reviews quarterly. Audit evidence pack updated monthly.
Reference Architectures
Edge or branch room
- 5 to 20 racks, 50 to 200 kW, single UPS with generator and surge capacity.
- Use case: latency-sensitive and residency-constrained workloads, local processing, and caching.
Primary facility
- 50 to 100 racks, 500 kW to 2 MW, dual UPS and chillers, diverse power feeds, diverse carrier entries, and meet-me rooms.
- Use case: banks, ministries, health providers, energy control rooms, media, and OTT.
Dual site with DR
- Production plus DR site with synchronous or asynchronous replication, DRaaS overlay, and scheduled failover tests.
- Use case: regulated workloads and zero tolerance for prolonged downtime.
Power and connectivity blueprint
Power
Hybrid design combining utility grid, generators, and optional solar or gas IPP. Fuel logistics and runtime monitoring, spares strategy for critical components, and maintenance windows that respect business cycles.
Connectivity
Carrier neutral meet me rooms, diverse fiber paths from multiple carriers, IX peering where available, satellite backup if required, and QoS per application class.
Security and compliance detail
Access and identity
Role-based access, MFA for admin actions, privileged access management, session recording, and periodic access reviews.
Data protection
Encryption at rest and in transit, key management with HSM options, data classification, retention schedules, and defensible deletion.
Monitoring and evidence
SIEM with log retention for at least one year online and a multiyear archive, configuration state tracking, change approvals, and audit trails visible to auditors.
Privacy governance
Consent and purpose limitation are captured in service definitions, the DPIA repository, the breach notification workflow, and the third-party processor registry.
Operations model and SLAs
Foundation
Managed
Secure
Resilient
Each tier adds monitoring depth, security coverage, and recovery capabilities.
