Why Choose This Product?

• The SYS-621BT-HNC8R is a strong choice for buyers seeking four independent dual-socket nodes in only 2U of rack space. Its 4TB-per-node DDR5 capacity, mixed PCIe 5.0/4.0 NVMe-SAS storage bays, SAS3 connectivity and PCIe 5.0 expansion make it adaptable to compute- and storage-heavy enterprise workloads. The 3000W redundant power design and liquid-cooling support further suit demanding deployments, while the BigTwin architecture helps organizations consolidate infrastructure without giving up independent node operation. For procurement, it is particularly relevant to HCI, scale-out storage and container environments and to modernization projects built around 4th/5th Gen Xeon technology.
