🧭 Edge Data Centers

Low-Latency Compute Close to Users, Machines & Sensors

Edge data centers (micro-DCs / MEC sites) place compute, storage, and networking near the point of use—plants, warehouses, hospitals, campuses, venues, city POPs—so apps get single-digit millisecond latencies, deterministic bandwidth, and local resilience.
SolveForce designs edge DCs as a system: rugged power/cooling, secure racks, structured cabling, leaf/spine fabrics, storage tiers, Zero-Trust access, and auditable ops—tied by deterministic backhaul to core DCs and cloud.

🎯 Outcomes (Why SolveForce Edge)

  • Latency ↓, determinism ↑ — single-digit ms local round-trip, QoS lanes, and priority traffic for control, vision, AR/VR, and OT.
  • Local resilience — continue operations through WAN incidents with cached data & local failover.
  • Zero-Trust by default — identity- & posture-aware access for users/devices; encrypted links; microsegmented apps.
  • Operational clarity — DCIM, SLO dashboards, runbooks, and evidence to SIEM/SOAR.
  • Cost-smart — right-size power/cooling, compact racks, and selective GPU/accelerator pools.

🧭 Scope (What We Build & Operate)

  • Form factors — micro-rooms, ruggedized racks/enclosures, curb/closet POPs, containerized modules.
  • Power & cooling — UPS (double-conversion), runtime sizing, genset tie-in; close-coupled/row cooling; liquid options for dense GPUs.
  • Racks & cabling — edge-rated cabinets, latching PDUs, cable management, MPO/MTP trunks; labeling & OTDR. → /racks-pdu • /structured-cabling
  • Network fabric — compact leaf/spine, 10/25/40/100G, EVPN/VXLAN, QoS; out-of-band mgmt. → /networks-and-data-centers
  • Backhaul — wavelength/lit/dark fiber, fixed wireless, LTE/5G, satellite; IPsec/MACsec/L1 as policy. → /wavelength • /fixed-wireless • /mobile-connectivity • /satellite-internet

  • Observability — DCIM + telemetry (power/thermal/network/storage/compute) → NOC/SIEM. → /noc • /siem-soar

🧱 Building Blocks (Spelled Out)

  • Latency budget — per-app targets (vision/PLC/OT ≤ 1–10 ms local; AR/VR interactive ≤ 15–20 ms).
  • Fabric — EVPN/VXLAN with Anycast gateways; QoS EF for control/voice; jumbo MTUs where safe.
  • Security posture — 802.1X on ports, RA/DHCP guard, ZTNA for consoles, vault for secrets, HSM/KMS for keys. → /secrets-management • /key-management • /encryption
  • Data path — local ingest → hot NVMe cache → parallel/object store at core/cloud; scheduled sync windows.
  • Environmental — temperature, humidity, dust/particulate, vibration; locking rails; tamper alarms.

🛠️ Reference Patterns (Choose Your Fit)

A) OT / Computer Vision at the Edge

Rugged rack, PoE for cameras, edge GPUs, NVMe scratch, mTLS to inference services; WAN-sync to core object store.

B) Retail / Branch Compute

2–4 node K8s/virtualization cluster; POS/loyalty apps; local cache; SD-WAN dual-path (fiber + LTE/5G); ZTNA for admin. → /sd-wan

C) Healthcare / Clinical

Low-latency image routing; ZTNA per app; PHI encryption, DLP, immutable backups; DR runbooks. → /dlp

D) Industrial / SCADA

Deterministic QoS; microseg enclaves per cell/line; fixed wireless backhaul; NAC profiling; NDR for anomalies. → /fixed-wireless • /ndr

📐 SLO Guardrails (Targets You Can Measure)

KPI / SLOTarget (Recommended)
Local RTT (edge client ↔ edge app p95)≤ 1–10 ms (use-case dependent)
Leaf↔Leaf fabric latency (p95)≤ 10–50 µs
Backhaul attach (metro on-ramp p95)≤ 2–5 ms to region border
Edge cluster failover (p95)≤ 60–120 s (node loss)
Power autonomy (UPS runtime)≥ 15–60 min (policy/site driven)
Evidence completeness100% (baselines, tests, changes)

SLO breaches open tickets and trigger SOAR actions (reroute, rate-limit, shed load, rollback). → /siem-soar
