INTEGRATED PRODUCT DESIGN

Knowledge Infrastructure Appliance

Spark AI Appliance is our integrated product design for this direction. Its goal is to bring the deployment, management and maintenance of knowledge preservation and AI applications into a unified architecture.

The technical design of Spark AI Appliance follows four directions. Specific capabilities, configurations and delivery scope are governed by confirmed product documentation.

Spark AI upright appliance exterior concept, showing an upper compute bay, a windowed optical chamber and a lower control and power bay. — Exterior concept illustration, not a finalized engineering design. Structure, dimensions, configuration and delivery scope are subject to confirmed product documentation.

Exterior design concept

A compartmentalized concept explores the integration of compute, optical archiving and maintenance access.

Separate compute bay

Plan dedicated space and cooling paths for compute modules.

Unified optical chamber

Organize drives, disc magazines and the dual-gripper mechanism within one chamber.

Service-oriented layout

Plan side maintenance access and separate control and power areas.

Knowledge Architecture

A proposed architecture for enterprise knowledge.

The architecture explores relationships among compute, retrieval, governance and storage. The layers shown describe design directions, not a confirmed delivery configuration.

Research framework

Hierarchical AI Memory Infrastructure

We study the data lifecycle across HBM → DRAM → NVMe → HDD → Optical. The goal: place knowledge where it best serves its current value, within governance and recovery constraints.

Illustrative placement, not a mandatory migration sequence. HBM and DRAM represent runtime memory, not durable archives; object storage is an access model, not a physical medium. NVMe identifies an interface, while SSD identifies a storage device.

Knowledge Activity (KA)

KA = f(access frequency, RAG hit rate, Agent invocation probability, timeliness, business value, recovery cost)

Agent invocation probability
Timeliness
Business value
Recovery cost

KA is a research decision framework, not a validated scoring algorithm. Weights, observation windows and thresholds require workload-specific validation; this diagram does not assert that every tier ships in the appliance.

Placement changes as knowledge value changes

The proposed policy promotes knowledge when demand rises and moves it toward capacity or archive tiers as activity falls. Reactivation includes retrieval, verification and loading into runtime memory when needed—not simply moving a file into HBM. Retention rules, permissions, integrity checks and recovery objectives constrain every transition.

Five measurable outcomes

Cost per 1,000 tasks: Allocated total cost / attempted tasks × 1,000. Include amortized hardware, software, operation, model/API, energy, migration and archive recovery costs over a disclosed observation period; report completion and failure rates alongside cost.
Retrieval latency: P50 / P95 in milliseconds, from retrieval request to verified context availability. Report cache hits, misses and archive reactivation separately.
Answer accuracy: Correct answers / evaluated tasks against a fixed reference set and scoring rubric. Use the same evaluator and include citation-grounding checks.
Stale-state rate: Tasks using expired or superseded state / evaluated state-dependent tasks. Define freshness windows and authoritative state versions before each run.
Energy consumption: Metered kWh per 1,000 tasks plus idle watts over the same observation period. Disclose device/system boundaries and include archive write, read and reactivation energy.

Fair comparison and tiering rules

Hold dataset/version, model/settings, prompts, workflow, compute, concurrency, usable capacity, redundancy and retention requirements constant. Test cold and warm cache separately; repeat runs and disclose configuration, sample size, duration and variation. Storage layout and tiering policy are the comparison variables.

Set acceptance thresholds for accuracy, freshness, latency and recovery before testing. Decide what can move to a lower tier only after these thresholds and permission, retention and integrity constraints are met, using measured cost and energy. Active state and strict low-latency data are not automatically archived: the benchmark does not assume all cold data belongs on optical media.

Technical design and customer value

The technical design of Spark AI Appliance follows four directions. Specific capabilities, configurations and delivery scope are governed by confirmed product documentation.

Coordinated storage tiering and knowledge retrieval

Design approach

Associate original file locations with retrieval entry points, and organize online indexes, caches and long-term archive tiers through defined policies.

Intended customer value

Balance everyday search needs with long-term preservation, while reducing the complexity of managing separate archive and retrieval workflows.

Searching an online index and restoring an original from cold storage are separate operations. Restoration time depends on the media, equipment, queue and file size.

Traceability to original sources

Design approach

Link retrieval results and AI answers to document versions, cited locations and original records, with defined handling when evidence is insufficient.

Intended customer value

Help users check the basis of an answer and assess the version and relevance of its sources.

Local deployment and controlled knowledge use

Design approach

Plan knowledge processing within enterprise environments, incorporating authentication, access authorization and model invocation boundaries into the architecture.

Intended customer value

Let enterprises plan where data is processed, who can use it and how external services connect, according to their business requirements.

Modular architecture for long-term maintenance

Design approach

Structure compute, storage and knowledge services as maintainable modules, with planned paths for data export, interface adaptation and component replacement.

Intended customer value

Provide a defined approach to data migration, knowledge continuity and system maintenance as models and hardware evolve.
