Celestica supplies Ethernet switch hardware for data-centre, AI/HPC and enterprise networks. DS5000 combines 64 800GbE OSFP ports, 51.2Tbps Tomahawk 5 switching and ONIE for compatible network operating systems. The 1.6TbE DS6000 family is vendor-declared shipping/ready to order, with air-cooled 3U DS6000 and hybrid-cooled 2OU ORv3 DS6001 configurations. Later roadmap wording and model-specific SONiC documentation make the quoted hardware/software release material to selection.
Technical detail
Core features
DS5000: 2U, 64×800GbE, 51.2Tbps; linked datasheet specifies 0–40°C operation, front-to-back airflow and redundant hot-swappable power supplies.
ONIE and compatible SONiC/NOS options; the May 2026 CLS SONiC 4.0.0 matrix includes DS5000 but does not list DS6000/DS6001.

Use & integration
Recorded applications
Data-centre leaf/spine and AI/HPC fabrics
Enterprise network infrastructure
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
DS5000 was announced shipping in October 2024 and is listed by OCP with an approved design contribution. April 2026 declares DS6000-series shipping; no named customer deployment was established, and July wording still refers to its roadmap.
Commercial availability
Commercial quotation/configuration through Celestica and listed solution providers. Confirm model revision, NOS licence/version, optics, cooling and acceptance; OCP listing is not defence qualification.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.

DS5000 is a 2U switch with 64 OSFP 800GbE ports and Broadcom Tomahawk5 silicon rated at 51.2Tbps. ONIE supports compatible NOS installation including SONiC; management includes Redfish/OpenBMC options. The sheet specifies 0–40 degrees C, 30kg, redundant 2000W PSUs and front-to-back airflow. These are data-centre ratings; PSU nameplate is not typical power draw.

The July28 OCP APAC article refers to DS6000 roadmap while discussing DS5000 demonstrations and open AI fabrics. This later shorthand is in tension with the April16 shipping/ready-to-order announcement; availability and software configuration should be confirmed per quote, rather than assuming all models are deployed or generally interoperable.
