SA3400D product photo

Status: Currently sold

A 12-bay 2U enterprise storage server from 2023 with two controllers, so if one fails the other takes over within minutes. Each controller has an 8-core Xeon D-1541 with ECC memory, and it takes dual-port SAS drives. It's built for business-critical uptime, not a small office.
