HPE S2L70C NVIDIA L40S 48GB PCIE Accelerator

HPE S2L70C NVIDIA L40S 48GB PCIe GPU Accelerator

The HPE S2L70C is a PCIe-connected GPU accelerator built around the NVIDIA L40S with 48GB of onboard memory — a configuration aimed at demanding AI inference, 3D rendering, and parallel compute workloads in rack-mount server environments. The dual-interface design (PCIe and Ethernet) gives deployment teams flexibility in how they surface compute capacity to the rest of the infrastructure stack.

Overview

The S2L70C slots into HPE's compute portfolio as a discrete accelerator option for organizations running GPU-intensive workloads inside ProLiant or compatible rack servers. With 48GB of GPU memory onboard, it handles large model inference batches, multi-stream media processing, and visualization tasks that would exceed the capacity of entry-level accelerator cards. The PCIe interface keeps installation straightforward — no proprietary interconnect fabric required — and the Ethernet interface supports network-accessible compute configurations depending on how your environment is provisioned.

At 3.74 lb, the card is within the weight range typical of full-height, full-length double-wide GPU accelerators, which is the form factor expected for the L40S class. Confirm your server chassis supports the physical slot dimensions and the required PCIe slot power delivery before ordering.

Key Features

• NVIDIA L40S GPU with 48GB memory: The 48GB frame means large language model inference, multi-instance GPU partitioning, and high-resolution visualization workloads won't hit a memory ceiling the way 24GB or 16GB cards do — relevant if you're running multiple concurrent inference jobs on a single card.
• PCIe interface: Standard PCIe connectivity means the S2L70C installs into any compatible HPE server slot without requiring proprietary interconnect hardware. No additional fabric switches or cabling beyond what your existing rack infrastructure already supports.
• Dual PCIe + Ethernet interface: The Ethernet interface alongside PCIe allows for compute-as-a-service configurations where GPU resources are addressable over the network — useful in shared infrastructure deployments where direct PCIe attachment to a single host is too limiting.
• 3.74 lb card weight: This is within the expected range for a dual-slot, full-length accelerator. It's relevant for dense chassis where cumulative card weight affects rail and shelf load ratings — check your chassis documentation for per-slot weight limits before populating multiple accelerator slots.

Integration and Compatibility

The S2L70C is sourced as an HPE-branded component, intended for integration with HPE ProLiant and compatible server platforms. Verify PCIe generation and slot power delivery against your target server's technical reference before purchasing — the L40S class of accelerator typically requires a high-wattage PCIe slot or supplemental power connectors. For AI/ML pipeline deployments, confirm your software stack supports the NVIDIA L40S device identifiers through your hypervisor or container orchestration layer. Country of origin is Taiwan (TW).

Frequently Asked Questions

Q: What interface does the HPE S2L70C use?

A: The S2L70C uses both PCIe and Ethernet interfaces, supporting standard slot installation in compatible HPE servers as well as network-accessible compute configurations.

Q: How much GPU memory does the S2L70C provide?

A: The S2L70C is built on the NVIDIA L40S with 48GB of onboard GPU memory, supporting large inference batches and multi-stream workloads.

Q: What does the S2L70C weigh?

A: The card weighs 3.74 lb. Verify per-slot weight limits in your target chassis before populating multiple accelerator slots.

Q: Where is the HPE S2L70C manufactured?

A: Country of origin is Taiwan (TW).

Q: Is the S2L70C compatible with non-HPE servers?

A: The S2L70C is an HPE-branded component. While PCIe is a standard interface, compatibility outside HPE-certified server platforms is not confirmed by available evidence — verify with your platform vendor before ordering.

James Everett

The HPE S2L70C pairs the NVIDIA L40S GPU with 48GB of onboard memory and a dual PCIe plus Ethernet interface — a configuration I'd look at closely for any deployment that needs both direct-attach and network-addressable GPU compute from a single card slot.

Technical Highlights:

• 48GB GPU Memory: Enough headroom to run multiple concurrent inference workloads or partition the GPU for multi-tenant environments without hitting memory walls that force job queuing.
• Dual Interface (PCIe + Ethernet): PCIe handles the primary host-attach path; Ethernet adds flexibility for compute-sharing architectures. Both interfaces confirmed from source evidence — not an assumption.
• Card Weight (3.74 lb): Meaningful in dense chassis builds. Full-length double-wide accelerators at this weight class need chassis rails and shelf ratings checked before you populate adjacent slots.

Deployment Considerations:

• Confirm PCIe slot power delivery and generation on your target HPE server before ordering — L40S-class accelerators typically draw 350W+ and require appropriate slot or supplemental power support.
• The available source evidence does not include thermal, operating temperature, or HPE firmware certification data for this SKU — validate those against HPE's server compatibility matrix for your specific ProLiant platform before committing to a multi-card configuration.

The S2L70C is a strong fit for HPE-centric AI inference infrastructure builds where 48GB per card and network-accessible compute are both requirements — particularly shared GPU cluster deployments in enterprise data centers running HPE ProLiant rack servers.
