Huawei unveils OceanStor M900 context memory storage for AI inference
At HUAWEI CONNECT 2026, Huawei introduced the OceanStor M900 Context Memory Storage, a new storage system designed to accelerate AI inference workloads in hyperscale data centers. The product addresses the challenges of ultra-long context windows and multi-turn inference in large language models by providing a fully shared memory space with PB-scale capacity. It leverages a global multi-tier KV cache over the UnifiedBus network, extending cache from DRAM to SSDs and delivering up to 64 PB per cluster. The system claims to reduce access latency to 60 microseconds, increase throughput to 40 TB/s, and cut token costs through adaptive KV-aware storage. This launch marks a shift in AI infrastructure towards deeper collaboration between compute, network, and storage resources.
Major AI infrastructure launch by Huawei, relevant to AI model deployment and performance in data centers.

High‑Bandwidth Flash Emerges as AI Memory Option
The report analyzes High Bandwidth Flash (HBF), a stacked-NAND packaging approach that mimics HBM stacking (TSVs + bonded controller/CBA) to deliver very high read bandwidth ( ~1.6 TB/s) while offering substantially more capacity (Sandisk states ~512 GB per stack). HBF trades higher latency and lower write endurance for much greater capacity-per-stack versus HBM, making it a candidate for storing model weights for inference decode workloads. SanDisk expects memory samples in H2 2026 and AI inference devices using HBF in early 2027. Sandisk and SK Hynix are collaborating on stacking and began an OCP standardization effort in February 2026. The piece outlines supply-chain implications, comparative power/cost metrics versus HBM4, and competitive players including Sandisk, SK Hynix, Samsung and YMTC.
WEKA & OCI Validate 10x AI Inference Throughput
WEKA and Oracle Cloud Infrastructure (OCI) published production-scale benchmarks showing WEKA’s NeuralMesh platform with Augmented Memory Grid dramatically improves long-context AI inference economics on OCI. Tested on a nine-node bare-metal H100 cluster with 100,000-token context windows, the configuration delivered ~10x more concurrent users, ~10x higher token throughput, and ~7x more tokens per GPU versus a DRAM-only baseline. OCI published the full methodology and results on its AI & Data Science blog (May 13, 2026). WEKA and Oracle executives said the approach removes GPU memory bottlenecks by expanding usable cache from DRAM to NVMe, enabling more efficient, cost-effective long-context inference at production scale.
Microsoft Unveils Maia 200 Inference Accelerator
ChipStrat interviewed Saurabh Dighe, CVP of Azure Systems and Architecture at Microsoft, about Maia 200 — Microsoft’s second-generation AI accelerator designed specifically to optimize inference economics. Maia 200 targets performance-per-dollar and performance-per-watt for inference, with architectural trade-offs that favor inference workloads over training. Key technical choices discussed include a much larger on-die SRAM, a memory hierarchy balancing SRAM, HBM and system DRAM, and a preference for a large Ethernet-based scale-up domain with a custom transport layer. Microsoft positions Maia 200 as complementary to merchant GPUs within a heterogeneous fleet, exposing capacity through Azure services rather than as a standalone product. The interview also emphasizes KV cache management for long-context workloads and the importance of software investments (compilers, kernels, pre-silicon tooling) ahead of silicon.
