Four Independent Nodes in Four Rack Units? TFNEW ZN-4A
TL;DR: TFNEW launched the ZN-4A, a 4-node multi-node server, on September 21, 2026. Four independent nodes — each a 14th/13th Gen Intel Core with DDR5, four SATA, two M.2 and 2x 2.5G Ethernet — fit in a compact chassis with multi-directional cooling and per-node CRPS power for datacenter, cloud and cloud-gaming density.

Core Specifications (with Plain-Language Terms)
The ZN-4A is a multi-node server: four fully independent servers in one chassis (176 mm tall, 718 mm deep), the architecture that concentrates node count per rack unit. Each node runs a 14th/13th Gen Intel Core processor on an Intel B760 chipset, with 4x DDR5 slots (16 across the chassis) at up to 7800 MT/s and up to 1024 GB total memory. Storage per node: 4x SATA ports and 2x M.2 (16 SATA + 8 M.2 chassis-wide). Expansion: 4x PCIe 5.0 x16 plus 4x PCIe 4.0 x16 slots across the chassis for NICs and controllers. Networking: 8x Intel 2.5GbE total — two per node. Power is 4x CRPS modules (550 W / 800 W / 1300 W options), one per node, so each node's power domain is independent; cooling is 12x 40 mm fans arranged for multi-directional airflow.

Why Four Nodes Is the Density Sweet Spot
Multi-node design pays off in the middle: two nodes (ZN-2A) prove the concept, eight (ZN-8A) maximize density, and four — the ZN-4A — hit the footprint most operators actually rack: four isolated single-socket nodes with two 2.5G uplinks each, in a chassis that still leaves per-node power (one CRPS module per node) and per-node expansion (PCIe 5.0/4.0 x16) available. Multi-directional cooling (12 40 mm fans) keeps hot nodes from stealing airflow from their neighbors, which is the silent killer of dense multi-node boxes.
Where It Fits
- Cloud gaming nodes: four isolated game-server instances per chassis
- Cloud computing platforms: dense single-socket VPS/container nodes
- Hosting and multi-tenant: per-node power and uplinks for tenancy isolation
- Edge colocation: shallow 718 mm chassis for space-constrained POPs
Why the Numbers Matter
- 4 nodes per chassis: four servers in one rack footprint
- 4x CRPS, one per node: a power fault on one node can't take down the others
- 8x 2.5GbE (2/node): per-node uplink bandwidth for instance traffic
- 16x DDR5 at 7800 MT/s: fast memory for game and VM workloads
- Multi-directional cooling: 12 x 40 mm fans balance airflow across nodes
What TF NEW Says
"Multi-node density only works if the nodes stay truly independent — power included," said a TF NEW product manager. "The ZN-4A keeps one CRPS per node, two 2.5G uplinks per node and PCIe slots per node, with 12 fans balancing airflow. Four isolated servers, one 176 mm chassis — the density case that actually fits how operators rack."
Quality and Availability
Every ZN-4A runs 48 hours of burn-in testing across all four nodes before shipping, with per-node power domains and all network paths validated in the factory. It ships deployment-ready with node-level management documentation and cluster guides.
