Eight ports wasn't enough. You're running a denser build — maybe a storage node, maybe a SAN back-end with more drives than the last card could handle. The 4350-16i doubles it: sixteen internal SAS or SATA ports at 12 Gb/s on one card. No RAID controller in the middle, no translation overhead. Just direct drive access to your ThinkSystem server's OS. Lenovo ISG made it, so the fit is clean and the cabling maps straight through. One card, sixteen drives, done
