A national sovereign cloud operator needed to move government workloads off foreign hyperscaler infrastructure. Haink designed and delivered the full three-layer stack: compute nodes, 100GbE leaf-spine fabric, and an all-flash shared storage pool. First VMs were live on week 14.
Haink supplied all hardware layers under a single contract. No coordination overhead between compute, network, and storage vendors.
2-socket AMD EPYC 9654 (192 vCPUs per host), 768 GB DDR5 ECC RAM, dual 25 GbE server NICs. Hyper-converged-ready: NVMe local cache per host for hot data. VMware vSphere + vSAN capable out of box.
4× spine switches (32-port 400GbE), 8× leaf switches (64-port 100GbE). All hosts connected at dual 100GbE. Separate out-of-band management fabric. ECMP routing, zero oversubscription at leaf-to-spine.
6× storage nodes, each with 12× 15.36 TB NVMe SSDs. 96 TB raw, ~55 TB usable (3× replication). 100GbE dedicated storage network (separate VLAN from compute traffic). S3-compatible object storage layer for backup and archive.
Workload audit, capacity modelling, network topology design. BOM locked on week 3; PO issued same day.
Compute nodes built and burn-tested. Switch firmware updated, port mappings pre-configured. Storage nodes assembled and tested in HK facility.
Air freight in bonded crates. Local customs agent coordinated by Haink. Hardware racked and cabled by Haink field team on arrival.
Network fabric brought up, storage pool initialised, first 50 VMs migrated from foreign hyperscaler. Production sign-off on week 14.
| Metric | Day-1 capacity | Phase-2 expansion headroom |
|---|---|---|
| vCPU count | 7,680 | +3,840 (20 additional hosts) |
| RAM | 30.7 TB | +15 TB |
| Usable storage | 55 TB | +55 TB (6 additional storage nodes) |
| VM density (estimated) | 400 VMs | 800+ at full expansion |
| Network bandwidth (host) | 2× 100 GbE | Spine upgrade path to 400GbE |
