Tyan B7126G68V4E4HR 1U2S NVMe/LFF Cloud Server Platform
The Tyan B7126G68V4E4HR is a 1U rack server platform built around a mixed drive bay layout — 4x large form factor (LFF) bays alongside 4x NVMe U.2 bays — aimed at cloud and storage-node deployments that need both bulk capacity and low-latency flash in a single chassis. At 26.77 x 17.26 x 1.69 in and 23.50 lb, it fits standard 1U rack positions without eating excessive depth budget in shallower cabinets.
Overview
This configuration targets integrators building out storage-dense or hyperconverged nodes where a single chassis needs to serve both throughput-heavy NVMe workloads and cost-per-terabyte LFF storage. The B7126G68V4E4HR's 4+4 bay split lets you tier storage within one node instead of splitting the workload across separate boxes.
Key Features
- 4x NVMe U.2 bays: Direct NVMe interface support means these bays connect straight to PCIe lanes rather than routing through a SAS/SATA controller — lower latency for cache tiers, databases, or metadata services that can't tolerate storage bottlenecks.
- 4x LFF drive bays: Large form factor bays accept higher-capacity 3.5-inch drives, keeping bulk storage cost-per-TB down for the workloads that don't need NVMe speed.
- 1U2S chassis at 1.69 in height: Standard 1U rack height maximizes node density per rack unit — a real factor when you're planning rack elevations for a storage cluster and every U counts.
- 23.50 lb chassis weight: Light enough for single-technician rack installs without a lift, which speeds up deployment day on multi-node builds.
Sourced through Tyan server hardware as part of the broader rack server lineup — worth reviewing alongside a storage capacity planning guide if you're sizing a mixed NVMe/LFF deployment, and pairing with NAS or SAN expansion if this node needs to scale storage beyond its onboard bays.
Full processor, memory, networking, and power specifications for the B7126G68V4E4HR were not available in current source documentation. Confirm CPU socket, RAM capacity, and PSU redundancy details before finalizing a build-out — those specs matter as much as bay count for a production storage node.
The B7126G68V4E4HR's bay layout is the story here — 4 LFF plus 4 NVMe U.2 in one 1U chassis is a deliberate tiering play, not a generic drive count.
Technical Highlights:
- 4x NVMe U.2 + 4x LFF bays: Splits fast-tier and bulk-tier storage in a single node instead of forcing a two-chassis design for tiered workloads.
- 1U height (1.69 in): Keeps rack density high — relevant when you're stacking multiple nodes in a storage cluster and U-count drives your colo or cabinet cost.
- 23.50 lb chassis: Manageable for a single installer during a rack-and-stack, without rack-lift equipment.
Deployment Considerations:
- Confirm CPU, memory, and NIC configuration with the actual build sheet before quoting a workload — bay layout alone doesn't tell you compute headroom.
- Mixed NVMe/LFF backplanes sometimes split PCIe lane allocation between the two bay groups — verify lane assignment if you're maxing out all 4 NVMe bays simultaneously.
A reasonable fit for a storage-tiering node in a small-to-mid cloud cluster where you want NVMe cache alongside bulk LFF capacity in one rack unit — confirm full compute specs before committing to a production build-out.
