Lenovo 4XC7A96457 Thinksystem Emulex LPE37102 32GB 2-PORT PCIE Fibre Channel

Lenovo 4XC7A96457 ThinkSystem Emulex LPE37102 32Gb 2-Port PCIe Gen4 Fibre Channel Adapter

Overview

The Lenovo 4XC7A96457 is a dual-port 32Gb Fibre Channel host bus adapter built for ThinkSystem servers that need direct, low-latency connectivity into enterprise SAN fabrics. Based on the Broadcom Emulex LPE37102 controller and riding a PCIe 4.0 host interface, this card delivers the bandwidth headroom modern all-flash arrays and high-density NVMe-oF storage targets demand — without the protocol overhead of iSCSI or the latency variability of converged Ethernet paths. If your storage team is running a dedicated FC fabric and your server team is provisioning ThinkSystem nodes, the 4XC7A96457 is the straightforward fit: two 32Gb ports, Gen 4 bus, hot-plug capable, sourced direct from Lenovo's channel.

Key Features

• 32 Gb/s per port (32,000 Mbit/s): Each port sustains up to 32 Gbps of FC throughput — double the bandwidth ceiling of legacy 16Gb adapters. On storage-intensive workloads like database logging, backup to tape, or virtual machine live migration over a FC SAN, that headroom prevents the adapter from becoming the bottleneck before the storage array does.
• Dual-port design: Two independent FC ports on a single card lets you present two separate paths to the fabric from one PCIe slot. That supports multipath I/O configurations (MPIO) without consuming a second slot — important on dense 1U ThinkSystem nodes where expansion slots are scarce.
• PCIe 4.0 host interface: Gen 4 PCIe doubles the per-lane bandwidth compared to Gen 3, so the bus can actually keep up with two concurrent 32Gb FC streams. If your ThinkSystem platform supports PCIe 4.0, you're not leaving bandwidth on the table at the host interface level.
• Hot-plug support: The adapter supports hot-plug, meaning it can be installed or removed from a running system without a full shutdown — relevant in environments with high-availability requirements where planned maintenance windows are tight or infrequent.
• Operating temperature range 0–55°C: Rated for standard data center thermal envelopes. The 55°C ceiling is typical for rack server accessories; it won't be an issue in a properly cooled row, but worth noting if you're deploying in edge racks or high-density blade enclosures that run warm.
• Storage temperature range -20–85°C: Broad storage range means the adapter handles cold-warehouse staging or unconditioned shipping environments without risk of component damage before installation.
• Operating humidity 5–95% (non-condensing): Covers standard data center humidity bands without requiring specialized environmental controls.
• Internal form factor: This is a standard PCIe add-in card designed for internal installation — not an external HBA. Verify your ThinkSystem chassis has an available full-height or low-profile PCIe 4.0 slot before ordering, depending on your specific server model's riser configuration.

Integration and Compatibility

The 4XC7A96457 is a Lenovo ThinkSystem option, meaning it is validated and listed in Lenovo's ServerProven compatibility program for supported ThinkSystem server platforms. The Emulex LPE37102 chipset has broad OS driver support across enterprise Linux distributions, Windows Server, and VMware ESXi — standard for FC HBAs in production SAN environments. On the fabric side, the card connects to 32Gb, 16Gb, or auto-negotiating FC switches; most enterprise directors (Brocade/HPE/Cisco MDS) will auto-negotiate down to the switch port's maximum supported speed if the switch fabric hasn't been upgraded to 32Gb yet. Verify your specific ThinkSystem server model and PCIe slot availability against Lenovo's ServerProven list before procurement — the adapter's compatibility scope is bounded by Lenovo's qualification matrix, not the Emulex chipset alone.

Frequently Asked Questions

Q: What servers is the Lenovo 4XC7A96457 compatible with?

A: The 4XC7A96457 is a Lenovo ThinkSystem option. Compatibility is validated through Lenovo's ServerProven program for supported ThinkSystem server platforms. Check Lenovo's ServerProven compatibility list for your specific server model and PCIe slot configuration before ordering.

Q: Does the 4XC7A96457 support hot-plug installation?

A: Yes. The adapter carries hot-plug support, allowing installation or removal from a running system without a full server shutdown, subject to the host platform and OS supporting hot-plug PCIe operations.

Q: What PCIe generation does the 4XC7A96457 use?

A: The adapter uses a PCIe 4.0 host interface. This provides sufficient bus bandwidth to support two concurrent 32Gb Fibre Channel streams without the host interface becoming a throughput bottleneck.

Q: Can the 4XC7A96457 connect to legacy 16Gb Fibre Channel switches?

A: The Emulex LPE37102 supports auto-negotiation with lower-speed FC fabrics, including 16Gb switches. The port will negotiate to the highest mutually supported speed. Confirm with your switch vendor's interoperability matrix for your specific fabric model.

Q: What is the maximum data transfer rate per port?

A: Each port supports up to 32,000 Mbit/s (32 Gb/s), which is double the throughput ceiling of a 16Gb FC port.

The 4XC7A96457 is one of those components that doesn't require much sales language — if you're spec'ing ThinkSystem nodes into a 32Gb FC SAN environment, this is the Lenovo-validated adapter for that job. The PCIe 4.0 interface is what separates this generation from the previous wave: with two 32Gb ports running simultaneously, you're pushing a theoretical 64 Gbps aggregate from a single slot, and Gen 4 PCIe has the per-lane bandwidth to sustain that without choking at the host interface.

Technical Highlights:

• 32 Gb/s per port: At 32,000 Mbit/s per port, each FC link runs at double a 16Gb port's ceiling — meaningful for NVMe-oF over FC workloads or high-throughput backup-to-SAN scenarios where adapter bandwidth was previously the ceiling.
• PCIe 4.0 host interface: Gen 4 x8 PCIe provides ~16 GB/s of bidirectional bandwidth — enough to fully saturate both 32Gb FC ports simultaneously without the bus becoming the constraint. Gen 3 platforms would cap this at ~8 GB/s, making the Gen 4 requirement on the ThinkSystem host side a real prerequisite to check.
• Hot-plug support: Live insertion and removal without server downtime is operationally significant in environments running rolling maintenance on HA clusters. Not all FC HBAs at this tier carry hot-plug — it's worth confirming your OS and chassis both support PCIe hot-plug before relying on it in production.

Deployment Considerations:

• Verify your specific ThinkSystem server model has a PCIe 4.0 slot available and that the riser configuration supports the card's form factor — Lenovo's ServerProven database is the authoritative source, not the chipset's generic compatibility list.
• The 10 lb weight in the distribution record reflects packaged shipping weight, not the card itself — don't use it for chassis weight-budget calculations; the bare adapter weight is not in the available evidence.

This adapter is the right fit for ThinkSystem deployments being provisioned into an existing 32Gb FC fabric — particularly where the storage team is running all-flash arrays or NVMe-based targets and the server team needs a validated, single-slot dual-path HBA without going outside Lenovo's option catalog.
