Services

Physical-layer infrastructure for three markets.

DDCA delivers blunt, written assessments and end-to-end advisory on fiber and copper infrastructure across data centers, small businesses, and homes — plus the AI compute, networks, WiFi, and Home Assistant automation that ride on top.

01

Data Center, Fiber, Copper & AI Compute Advisory

For colocation tenants, enterprise IT teams, hyperscale tenants, and integrators who need a second set of eyes before a six- or seven-figure commitment. Fiber and copper plant, AI-hall design, RFP support — blunt, written assessments you can hand to a board or a CFO.

  • Facility evaluation. Power density, cooling topology (air, rear-door, direct-to-chip), redundancy, security, connectivity, and operator track-record reviews for colocation, expansion, or migration.
  • AI data-center readiness. GPU hall planning, 50–130 kW/rack power & cooling strategy, liquid-cooling readiness, east-west fabric, InfiniBand vs. Ethernet trade-offs, and rear-door heat exchangers.
  • Fiber-optic & SAN design. Storage-area fabric topology, zoning, ISL sizing, switch selection across Brocade and Cisco MDS; single- & multi-mode plant, OS2 vs. OM4/5, MPO trunks, and DWDM for metro and OSP routes.
  • Copper structured cabling. Cat 6, 6A, and Cat 8 plant for in-rack, in-row, and inter-room runs; PoE++ (60 W / 90 W) budgeting, patch-field layout, MDA/HDA design, grounding, labeling, and certification testing to TIA-568 / ANSI/TIA-942.
  • Bill of materials evaluation. Line-by-line review of vendor quotes for compute, storage, networking, optics, and cabling. We flag mis-sized parts, missing SFPs, optimistic licensing, and over-spec.
  • In-rack layout, design & review. Rack elevations, U-by-U layout, weight and power distribution, cable management, airflow containment, and structured cabling plans — for new builds and audits.
  • Vendor & RFP support. Drafting RFPs, scoring responses, and sitting in on vendor pitches as your technical advocate — with zero commissions from any vendor.

Small-Business, Office & Home Networks, WiFi & Home Assistant

The same engineering rigor, applied to the small commercial site, the remote / home office, and the residence. Fiber and copper structured cabling, enterprise-grade switching and WiFi, and a self-hosted automation backbone — designed so executives can work from home the way they would from a corporate floor, small businesses get a network that scales, and homeowners get a system that is reliable, private, and aging-in-place ready — not a brittle pile of cloud apps.

  • Small-business, office & home networks. Wired-first LAN backbone with PoE switching, VLAN segmentation, firewall posture, and remote-access strategy for small commercial sites, branch offices, home offices, and residences.
  • Structured cabling — fiber & copper. Low-voltage rough-in for new construction and retrofit: Cat 6A copper to every workstation and access point, single-mode fiber risers between floors and outbuildings, patch panels, IDF/MDF closet design, grounding, labeling, and certification testing.
  • WiFi design & survey. WiFi 6E and WiFi 7 access-point placement, channel and band planning, roaming, and mesh-vs-wired-uplink decisions — with after-install validation surveys for whole-home and small-office coverage.
  • Home Assistant automation. Self-hosted Home Assistant builds — lighting, climate, locks, sensors, energy, and presence — with local control, off-cloud fallback, Zigbee/Z-Wave radios, and integrations across Lutron, Hue, Ecobee, Sonos, Ubiquiti, and Reolink.
  • System design. Low-voltage backbone, lighting and shade control, climate, access, AV, and intercom — specified for longevity, not novelty.
  • Small-business automation. Lighting, access control, conference-room AV, network segmentation, and basic BMS integration for offices, retail, and professional practices.
  • Platform selection. Independent guidance across Home Assistant, Lutron, Crestron, Control4, Savant, and UniFi. We pick what fits the household or business, not what pays a commission.
  • Integrator review. Second-opinion review of integrator proposals, scope, and pricing before contracts are signed — and during execution if things drift.
  • Resilience & privacy. UPS sizing, off-cloud fallback, segmentation, and privacy posture for connected devices, cameras, and voice assistants.
