What is VNX+? A Complete Guide to the ANSI/VITA 90 Modular Standard
One of the long-term challenges in defense and aerospace is the expectation that each new generation of hardware must do more: process faster, handle complex data, integrate more I/O types, all while simultaneously shrinking the weight and box it sits in. A modern open standard VNX+ emerged specifically to address this tension by extending the architecture of established rugged computing frameworks into a smaller physical envelope. This blog covers the VNX+ standards in full: what is VNX, what is VNX+, why was VNX+ standard developed, how the VITA 90 sub-standard family is organized, and where this technology can be deployed.
What is VNX?
VNX was first standardized under VITA 74 and introduced as a compact, modular computing architecture built to serve applications where the physical constraints of conventional VPX made deployment impractical. While VPX modules were engineered for maximum throughput in somewhat larger chassis, the applications required something considerably more compact without abandoning the interoperability and modularity that open standards provide, hence VNX standard was born.
What is VNX+?
VNX+, at a glance, is the evolved form of the VNX standard, published under the ANSI/VITA 90 designation and SOSA™ principles. The progression from VITA 74 to VITA 90 allowed a fundamental change in the module sizes, which was a technical boundary that VITA 74 had drawn. VITA 90 redrew those boundaries to accommodate compact modules with almost 70% less than the size of 3U boards/cards, and integrated serial interconnects for expanded I/O needs of current generation systems.
Design Philosophy
VNX+ does not position itself as a replacement for VPX. The two coexist as complements within the same broader ecosystem. VPX remains the appropriate choice when the available volume is larger, the per-slot power budget is higher, or the processing density requirements exceed what VNX+ modules can deliver. VNX+ fills the space below VPX, the applications where SWaP budgets are tighter, and platforms are smaller.
Connector Architecture and Signal Integrity
VNX+ adopted the Samtec SEARAY™ connector family, reducing the electrical path length for the signals most vulnerable to degradation, which is what allows the connector to support the latest data computing requirements reliably without additional materials or redesigns.
The VITA 90 Family of Standards
VITA 90 is structured as a coordinated family of related specifications rather than a single monolithic document. Each sub-standard addresses a distinct technical domain within the VNX+ ecosystem. Together they cover the full scope of what a system designer needs to deploy a compliant, interoperable VNX+ system.
VITA 90.0: VNX+ Base Standard
This is the root specification from which all other VITA 90 profiles/standards derive. It establishes the module widths, the connector pinout, and the compliance requirements that every VNX+ module must satisfy regardless of its function. All boards marketed as VNX+ must conform to 90.0.
VITA 90.1: VNX+ Profile Tables
Slot profiles define how modules are classified for compatibility purposes. VITA 90.1 formalizes the naming conventions and profile definitions that make it possible for a module from one manufacturer to operate correctly in a slot defined by another.
VITA 90.2: VNX+ Optical and RF Connector Modules (Type 2)
Where standard connector pins carry electrical signals, some applications require high-density coaxial an optical interconnects within the standards under VITA 90.0. It supports RF and video signaling, along with other critical signals between a PIM (Plug-in Module) and corresponding slot.
VITA 90.3: VNX+ Power Supply and Storage Modules
Power conversion and distribution within a VNX+ chassis are governed by VITA 90.3. This sub-standard defines how power supply modules interact with the backplane and what protections or capabilities are required.
VITA 90.4: VNX+ Cooling and Mounting Systems
Mechanical reliability in high-vibration environments depends on more than a tight connector fit. VITA 90.4 specifies the retention and thermal management system features in VNX+ systems, including wedgelock retainers, mounting hardware, retention mechanisms.
VITA 90.5: Space VNX+
The demands of orbital and space applications gave rise to the VITA 90.5 standard. It was developed to address considerations in space-grade systems, such as thermal resilience, non-field repairable platforms requiring enhanced redundancy, and system management.
VITA 90.6: Signal Integrity Compliance
The VITA 90 systems must meet the signal integrity compliance standard, which is to be modeled after the VITA 68 standard for VPX platforms.
VITA 90.7: VNX+ Optical and RF Connector Modules (Type 7)
This sub standard defines the open standard for optical interconnect and high density NanoRF coaxial interconnect in VNX+ systems to support video, RF, and optical signal use cases.
Where VNX+ Can be Used
The adoption profile of VNX+ reflects the kinds of programs that face the most acute SWaP pressure. VNX+ has found its strongest footing in platforms where every ounce and every inch carries a cost, and where the ability to swap a module rather than redesign a board provides genuine value.
Key Application Areas
Military, aerospace, and industrial
UAVs, missiles, UUVs, cube sats, and satellites
Space-constrained harsh environments
Conclusion
In conclusion, VNX+ is the result of a serious, well-engineered approach to rugged small form factor computing. VITA 74 established the foundational architecture, and VITA 90 took that foundation and rebuilt the technical ceiling, expanding thermal capacity, accelerating serial interconnect support, and formalizing I/O. The result is an ecosystem that can host any computing hardware that complies with the VITA 90 standard.
