Key Features
A Compact Hybrid Storage Layout
Use qualified SATA HDDs or SATA SSDs in the four main bays and compatible M.2 NVMe SSDs in the internal slots. SSD use as a storage pool or cache depends on the operating system and storage design. The M.2 modules are not hot-swappable.
Processor Choice Without Ambiguity
The Pentium Gold G7400 configuration provides two cores and four threads; Core i3-12100 provides four cores and eight threads. The selector names the processor and installed memory together so two offers with the same RAM are not confused.
Start at 2.5GbE and Expand Deliberately
Two RJ45 2.5GbE ports are built in. Faster 10GbE or 25GbE networking is optional through a compatible PCIe adapter, rather than part of the base specification. Match the switch, cabling and storage performance to any upgrade.
Storage Services Beyond a Shared Folder
