For a 45-user design firm, we delivered a right-sized, enterprise-grade platform without the noise or power draw of a full rack. We built a quiet tower server with ECC memory, redundant platinum PSUs, mirrored NVMe for the hypervisor, and ZFS RAID10 for data over 10Gb networking. On top, we deployed Proxmox VE with standardized VM templates and VLAN-segmented services (Active Directory, file/print, and the line-of-business app). Backups follow a 3-2-1-1 pattern—local snapshots plus immutable off-site object storage—with a 15-minute RPO and ~1-hour RTO verified in quarterly recovery tests. Security is baked in: UEFI Secure Boot, TPM-backed encryption at rest, least-privilege access, and 24×7 monitoring/patching under a defined SLA and change-control process. We documented everything in an asset inventory and runbook for smooth handoffs and lifecycle management. Result: apps run ~3× faster, power usage dropped ~40%, and new VMs deploy in minutes—delivering Top-Tier quality with enterprise discipline.
