Overview

The ThinkSystem RAID 940-8i, part number 4Y37A09729, pairs a PCIe 4.0 interface with an 8GB flash cache. It offers eight internal ports for 12Gb SAS and 6Gb SATA drives.

Supported RAID levels are 0, 1, 10, 5, 50, 6 and 60, which includes single and dual parity. The large cache helps write-heavy workloads such as databases and virtual machine storage, and the flash design protects data held in cache.

It fits ThinkSystem servers with PCIe 4.0 slots where you want hardware RAID with serious caching. Confirm server compatibility and cabling before ordering, and decide which RAID level matches your capacity and protection goals.

The adapter is offered new or refurbished, each with 1 year or 3 years of warranty. No used offer is listed. Include the number of adapters in your RFQ and a price will follow by email.
