About the 4XC7A77485
4XC7A77485 is Lenovo's dual-port Gen 7 64Gb Fibre Channel host bus adapter for ThinkSystem V3 servers, based on the Broadcom Emulex LPe36002 silicon. Built for PCIe 4.0 architectures and all-flash NVMe SAN deployments, it delivers up to 5.0 million IOPS and provides line-rate 64Gb/s throughput on each port with end-to-end NVMe over Fibre Channel hardware acceleration.
Compatibility
Engineered specifically for ThinkSystem V3 rack servers including SR650 V3, SR630 V3, SR645 V3, and SR665 V3. Plugs into PCIe 4.0 x8 or x16 slots. Auto-negotiates with 64Gb, 32Gb, and 16Gb Fibre Channel fabrics. Fully supported on VMware ESXi 7.0/8.0, Red Hat Enterprise Linux 8/9, and Windows Server 2022.
How to identify a genuine unit
The low-profile card features two 64Gb SFP+ cages and an advanced silver heatsink covering the Emulex Gen 7 controller. Lenovo option part number 4XC7A77485, FRU part number 4XC7A77486, and feature code BNJ3 are clearly printed on the barcode label. Reports subsystem vendor ID 17AA in system management tools.
Buying used
Inspect both 64Gb SFP+ optical transceivers for intact release bails and clean optical interfaces. Confirm that the card establishes 64Gb link speed on Gen 7 switches. Verify that the server UEFI reports valid WWPNs and that firmware updates via Lenovo XCC succeed.
