Hardware

Cisco AI PODsHardware

Pre-validated modular AI infrastructure bundles that combine Cisco UCS servers, NVIDIA GPUs, Nexus 9000 400G/800G switching and management software into single orderable stacks for AI inferencing, training and fine-tuning.

Cisco AI PODs for CollaborationHardware

Turnkey on-premises AI appliance that runs real-time speech transcription for Cisco collaboration deployments locally, for customers with data-sovereignty requirements that rule out cloud AI services.

Cisco Nexus Hyperfabric AIHardware

Cloud-managed full-stack AI cluster sold as hardware plus software plus service, packaging Cisco 6000 and N9300 series switches on an 800GbE back-end fabric, UCS servers with NVIDIA H200 GPUs and BlueField DPUs, optional VAST storage and NVIDIA AI Enterprise under the Hyperfabric cloud controller.

Cisco Silicon OneHardware

Unified programmable networking-silicon architecture for AI, hyperscale, data-centre, service-provider and enterprise routing/switching, spanning five series (G/P/E/K/A) of chip families.

SK Hynix

Hardware

CMM-DDR5Hardware

CXL 2.0 memory module that expands and pools DDR5 capacity and bandwidth beyond the CPU's own channels for AI and high-performance computing servers, with a 96GB version through customer validation and a 128GB 1bnm version following.

HBM3EHardware

Fourth-generation high-bandwidth memory that vertically stacks up to 12 DRAM layers for 36GB at 9.6Gbps, sold to GPU and AI accelerator makers for AI server packages.

HBM4Hardware

Fifth-generation high-bandwidth memory with 2,048 I/O terminals and over 10Gbps operating speed, roughly doubling HBM3E bandwidth for next-generation AI accelerators.

PEB000 SeriesHardware

PCIe Gen5 enterprise SSD series in E1.S form factor with in-house ASIC and V8 4D NAND, power-optimised for AI servers and NVIDIA RVL-qualified for GB200 -- one model shipping today, PEB110 (1,920-7,680GB, 20W, mass production).

PS1000 SeriesHardware

PCIe Gen5 enterprise SSD series with in-house ASIC and V7 4D NAND for high-performance datacenter workloads, supporting up to 16TB in U.2/3 and the newer E3.S form factor -- two models shipping today, PS1010 and PS1030.

SOCAMM2Hardware

192GB LPDDR5X-based low-power memory module built on the 1cnm process and designed as main memory for AI servers, delivering over double the bandwidth of conventional RDIMM at over 75% better power efficiency.

No counterpart

Cisco sells these in a stack layer with no product recorded for SK Hynix yet — nothing on the other side to compare them against.
