Lenovo ThinkSystem DB730S
The ThinkSystem DB730S is Lenovo's flagship Gen 7 Fibre Channel enterprise SAN switch, built on OEM Brocade G730 hardware. Providing ultra-dense 64Gb/s connectivity across up to 128 line-rate ports in a compact 2U form factor, it utilizes 96 SFP+ ports alongside 16 double-density SFP-DD optical ports to maximize port count without sacrificing rack space. The switch cuts latency by up to 50% compared with Gen 6, making it ideal for NVMe over Fibre Channel flash storage clusters and high-frequency transactional financial platforms. Buyers in the refurbished market should check Fabric OS version compatibility, verify licensed port allocations, and confirm that dual 1100W power supplies and high-velocity cooling fans operate cleanly.
