Lenovo ThinkSystem RAID 940-8i 8GB Flash PCIe Gen4 12Gb/s Adapter

Same 940-8i backbone as the 4GB model, but double the flash-backed cache. If your workload is write-heavy — database commits, virtualisation snapshots, batch processing that hammers the disk queue — that extra 4GB of cache is the difference between steady throughput and a latency spike that makes your users notice. Eight internal ports, PCIe Gen4 host link, 12Gb/s drive interface. Slot it in, build your arrays, and stop watching your I/O wait times climb

• 8 internal SAS/SATA ports for ThinkSystem servers
• 8GB flash-backed write cache — double the buffer of the 4GB variant
• PCIe Gen4 host interface with 12Gb/s drive links
• Hardware RAID offload keeps CPU free for application workloads
• Genuine Lenovo ISG component, managed via XClarity
