Overview
Product overview
The NVIDIA Mellanox MSB7890‑ES2F is an unmanaged 100Gb/s InfiniBand smart switch designed for large‑scale data center deployments requiring centralized fabric management. Part of the NVIDIA SB7800 series, this switch delivers 36 QSFP28 ports operating at 100Gb/s per port, with an aggregate non‑blocking throughput of 7.2 Tb/s and ultra‑low port latency. Unlike its managed counterpart (MSB7800), the MSB7890‑ES2F is optimized for external management via NVIDIA Unified Fabric Manager (UFM), enabling data center operators to efficiently provision, monitor, troubleshoot, and maintain modern data center fabrics at scale. The MSB7890‑ES2F features the same high‑performance hardware as the managed SB7800 series, including an onboard dual‑core x86 CPU for switch hardware management (firmware, power supplies, fans) while relying on external Subnet Managers for fabric orchestration. With support for NVIDIA SHARP in‑network computing technology, the switch offloads collective operations from CPUs to the network fabric, dramatically accelerating MPI and deep learning workloads. The MSB7890‑ES2F variant features P2C (port‑to‑power) airflow, making it suitable for data center cooling architectures where cold air is supplied from the port side. Management Note: MSB7890-ES2F is an unmanaged switch variant optimized for external management. While it includes onboard hardware for basic chassis monitoring, fabric management (Subnet Manager) must be provided externally via NVIDIA UFM, OpenSM, or other standards‑compliant InfiniBand Subnet Managers.
Key features
- 100Gb/s InfiniBand per port – 36 QSFP28 ports delivering full bidirectional bandwidth with non‑blocking architecture.
- 7.2 Tb/s Aggregate Throughput – High‑density switching capacity in a compact 1U form factor.
- Unmanaged SKU for External Control – Optimized for centralized management via NVIDIA UFM platform; ideal for large‑scale fabrics requiring unified orchestration.
- In‑Network Computing Acceleration – NVIDIA SHARP technology offloads collective operations from CPUs to the switch fabric, reducing MPI operation time and freeing valuable CPU resources.
- UFM Ready – Seamless integration with NVIDIA Unified Fabric Manager for advanced telemetry, predictive analytics, and automated fabric orchestration across hundreds or thousands of switches.
- Redundant & Hot‑Swappable Components – 1+1 redundant power supplies with 80 Plus Gold certification, plus hot‑swappable fan modules for maximum availability.
- Energy Efficient Design – ATIS weighted power consumption as low as 122W for a fully populated system; dynamic power scaling reduces consumption when ports are not fully utilized.
- Flexible Cooling Options – P2C (port‑to‑power) airflow configuration (MSB7890-ES2F) with front‑to‑rear cooling.
Typical applications
- Large‑Scale AI & ML Clusters – GPU‑based systems requiring centralized fabric management and telemetry across hundreds or thousands of nodes with UFM orchestration.
- Hyperscale Data Centers – Fat‑tree, DragonFly+, and multi‑dimensional torus topologies managed through UFM for maximum efficiency and unified control.
- High‑Performance Computing (HPC) – Research labs, national labs, and universities where external fabric managers provide enhanced monitoring and automation capabilities.
- Enterprise & Cloud Service Providers – Environments requiring unified control plane across multiple switch fabrics with advanced telemetry and predictive analytics.
- Top‑of‑Rack (ToR) with Centralized Management – High‑density 100Gb/s leaf connectivity with fabric‑wide visibility and automated provisioning.
