Description

The 01KR581 is Lenovo’s official **ThinkSystem QLogic QL45212 Flex 50 Gb 2‑Port Ethernet Adapter**, a high-performance networking card designed for Flex, BladeCenter, and ThinkSystem servers. Based on Cavium’s 8th-gen FastLinQ ASIC, it delivers up to 50 Gb/s speeds via PCIe 3.0 x16, with features like RoCE, RoCEv2, iWARP, SR-IOV, and NIC partitioning for robust virtualization and scaling support .

Available new from resellers like ServerSupply with a 90-day warranty, or refurbished from Renewtech (35+ units, 1-year warranty) the adapter balances cutting-edge networking capability with broad support and cost flexibility.

Withdrawn from active marketing (per Lenovo Press, last updated Sep 30, 2024), it remains highly relevant for legacy and transitional infrastructure moving to 25/50Gb Ethernet while ensuring coexistence with existing 10Gb networks.

Key Features

  • Dual 50 Gb/s Ethernet ports over PCIe 3.0 x16
  • Support for RoCE, RoCE v2, iWARP, SR‑IOV, and NIC partitioning technologies 
  • Perfect for Lenovo Flex System, Blade, and ThinkSystem servers
  • Backward-compatible with 10/25 Gb networks using flexible speeds 
  • Designed for virtualization and high-throughput use cases
  • Available new (90-day warranty) or refurbished (1-year warranty) options
