At a glance

Structured summary for architects, buyers, and assistants evaluating this platform.
NTS Elite APEX 4U GPU AI Server – Intel Xeon 6900, 8-GPU is an engineer-to-order 4U rackmount platform from New Tech Solutions (RackmountNTS), staged and validated in Fremont, California for AI training, inference, and HPC.
Buyers use this page to confirm form factor, accelerator and storage options, and contract-ready quoting. Configure CPU, memory, GPU, drives, and networking below; NTS returns a validated BOM with firmware baselines, burn-in evidence, and CLIN-aligned documentation for SEWP V, ITES-4H, GSA, and SLED cooperatives when your program requires them.
Integration is owned end-to-end: rack elevation, power and cooling checks, imaging, and serial-tracked acceptance—so site install is not a first-time assembly. Lifecycle support follows the same staging records used at handoff.

NTS Elite APEX 4U GPU AI Server – Intel Xeon 6900, 8-GPU is quoted engineer-to-order by New Tech Solutions (RackMountNTS). Use Configure to select CPU, memory, accelerators, storage, and networking; NTS validates power, cooling, firmware, and drivers in Fremont, California before systems ship.
Federal, defense, and SLED programs can align the same BOM to SEWP V, ITES-4H, GSA MAS, or cooperative vehicles when the SOW allows. Commercial buyers receive the same staging discipline, serial-tracked acceptance, and lifecycle support path after handoff.
Share workload notes, target GPU or CPU counts, fabric preference (Ethernet, InfiniBand, or NVLink where applicable), rack power budget, and delivery window through contact NTS or Request a Quote. We return a validated option set with lead times, dual-source notes when required, and a package ready for contracting review.
Related reading: AI and GPU infrastructure, data center and HPC, BOM validation, and contract vehicles. From pilot nodes to multi-rack cells, NTS keeps one design authority across chassis, accelerators, and storage so scale-out does not restart engineering after the first system lands.
After you select options in Configure, pricing updates in real time. Request a Quote to receive a package with lead times, dual-source notes when required, and acceptance documentation aligned to your receiving process. Gold SKUs ship as fixed platforms; configurable SKUs remain engineer-to-order with the same Fremont staging path.
Questions about GPU count, liquid cooling, InfiniBand or Ethernet fabrics, storage density, or contract-vehicle packaging can be answered from this page’s overview, FAQ, and Configure workbench—or by contacting an NTS specialist with your draft BOM.
NTS supports commercial, federal, defense, and SLED buyers with the same engineering process: design review, parts validation, assembly, firmware and driver prep, and ship-ready documentation from our Fremont facility.

    How NTS configures and delivers NTS Elite APEX 4U GPU AI Server – Intel Xeon 6900, 8-GPU

    New Tech Solutions (RackMountNTS) treats NTS Elite APEX 4U GPU AI Server – Intel Xeon 6900, 8-GPU as engineer-to-order programs—not drop-ship SKUs. We validate power, cooling, PCIe or NVLink topology, fabric attach, imaging, and spare FRUs in Fremont, California before systems ship so receiving teams start from a known-good baseline.

    Federal, defense, and SLED buyers can align the same BOM to SEWP V, ITES-4H, GSA MAS, OMNIA, NASPO, TIPS, Texas DIR, and other vehicles listed on our contracts pages when scope allows. Commercial and research teams get the same staging discipline without the CLIN wrapper.

    Share a draft part list, workload notes, and delivery constraints through contact NTS. We return options with lead times, dual-source notes when required, and a quote package ready for contracting review. Related guides: AI and GPU infrastructure, data center and HPC, and BOM validation best practices.

    From pilot nodes to multi-rack cells, NTS keeps one design authority across chassis, fabric, and storage so scale-out does not restart engineering from scratch after the first rack lands.

    Every platform listed here can be quoted with validated options for CPU, memory, accelerators, storage, and networking. NTS documents the as-built configuration, serials, and acceptance notes so receiving and cybersecurity teams have a clear baseline when the hardware arrives. Ask for a pilot node or a multi-rack cell — the design authority stays the same. For SEWP V, ITES-4H, GSA MAS, and cooperative vehicles, keep the technical BOM identical and wrap the CLIN language at quote time.
