The IBM System Storage DS3400 Model 41E (part 1726HC4) is a 2U rack-mountable disk array designed for mid-range enterprise storage environments. It features 12 SAS drive bays with dual Fibre Channel 4Gbps controllers for redundancy and load balancing. The array supports mixed SAS drive configurations and includes integrated RAID capabilities (RAID 0, 1, 5, 6, and 10) for data protection. Typical deployments include virtualization hosts, database servers, and consolidated file storage where moderate to high throughput and availability are required. The external form factor integrates with standard 19-inch racks and connects via Fibre Channel to SAN-attached servers, compatible with IBM's enterprise storage management tools and Windows, Linux, and AIX operating systems. Each unit has been tested and is guaranteed; available via quote from G5 Network Group.
