Infinity Sentinel Essential | Office Infrastructure Server | EPYC 4545P

Most offices of 5 to 25 people still need a few services on site: a domain controller so staff sign in with one account, shared folders with permissions, print queues, the database behind a line-of-business application, and somewhere for backups to land. Spread across ageing towers or a desktop NAS, those jobs are hard to patch, hard to back up and hard to fix when nobody is in the office. Infinity Sentinel Essential brings them onto one server that fits an office closet or comms shelf, needs no rack and can be managed remotely.

A 16-core, 32-thread AMD EPYC 4545P (65 W) runs on an ASRock Rack B650D4U-2L2T/BCM server board with 64GB of DDR5 ECC unbuffered memory, one module per channel. Two Kingston DC2000B 480GB enterprise NVMe drives with power-loss protection are mirrored for the host and virtual-machine system disks, and two 16TB Seagate IronWolf Pro 7200 rpm drives are mirrored for shared data (16TB usable). The SilverStone CS382 tower has eight hot-swap bays, four of them wired to the board as standard, so the data pool can grow to four drives. Two 10GbE ports, two 1GbE ports and a dedicated IPMI port for remote power control, console access and hardware monitoring are built into the board, and a Noctua NH-D9L cooler and an 850W power supply complete the build.

Proxmox VE 9 is the host operating system, with a one-year Proxmox VE Basic subscription registered to your organisation, so the domain controller, file server and application servers run as separate virtual machines that can each be backed up and restored on their own. Windows Server runs as a guest operating system and is licensed separately: supply your own Windows Server 2025 licence or have us quote it. Microsoft licenses every physical core with a 16-core minimum per server, so this 16-core processor needs no additional core licences; Standard edition covers two Windows Server virtual machines, and each user or device needs a Windows Server CAL. Windows Server with Hyper-V on bare metal (the board maker lists Windows Server 2022 and 2025 for this processor) and Ubuntu Server LTS (no licence fee) are also available.

Choose Essential when the office needs infrastructure services, not just storage: for file storage and backup alone, an Infinity Vault NAS is the simpler fit. Step up to Infinity Sentinel Professional for SQL-backed applications, Remote Desktop, more virtual machines, ECC registered memory, a hot-swap SSD pool and redundant power in a rack.

Every server has its BIOS and BMC firmware updated and completes a 72-hour burn-in with a written report, during which we also validate Proxmox VE on this platform. It ships with both ZFS pools built, VLAN-aware networking, the BMC on a separate management network and an as-built document, followed by a one-hour remote handover. Options include 128GB of memory (four modules run at 3600 MT/s), the 16-core EPYC 4585PX with 128MB of L3 cache and a larger cooler, four-drive pools of 16TB or 24TB drives, a 1U rackmount version with redundant power supplies on the same motherboard, a 1500VA sine-wave UPS with automatic shutdown, and on-site installation, Windows Server domain build, backup configuration, data migration and monitoring services.

The tower has a single power supply and is one server, so it is not high availability: we recommend a second domain controller on separate hardware, and because mirrored drives are not a backup, back the server up to separate hardware such as an Infinity Vault and keep an off-site copy. Covered by our 3-Year Hardware Warranty and Lifetime Technical Support. Configured and quoted per project; built and tested in Ontario.
