About the Supermicro SYS-421GL-TNRT
The Supermicro SYS-421GL-TNRT supports NVMe-oF, iSCSI, FC, NFS, and SMB protocols across flash, hybrid, and archive storage classifications, positioning this 4U rackmount system as a versatile enterprise-grade solution for demanding data center workloads. Built on the Supermicro 4U Ultra GPU chassis, the SYS-421GL-TNRT accommodates dual 4th Gen Intel Xeon Scalable processors (Sapphire Rapids) in LGA4677 sockets, delivering exceptional compute density for organizations requiring high-performance storage and accelerated processing in a compact footprint. The system provides up to 32 DDR5 ECC Registered DIMM slots—16 per CPU—supporting up to 4TB total memory capacity, while eight 2.5-inch hot-swap NVMe/SATA/SAS drive bays enable flexible storage configurations. PCIe 5.0 connectivity and support for up to 10 double-width GPU accelerators make this platform ideal for GPU-intensive workloads, further augmented by dual 100GbE QSFP28 ports via OCP 3.0 mezzanine and onboard 10GBase-T Ethernet interfaces.
Storage architects, AI infrastructure teams, and enterprise IT procurement professionals select the SYS-421GL-TNRT when they need extreme throughput, low-latency data access, and accelerated compute without sacrificing reliability. Redundant 3000W Titanium-level power supplies and hot-swap redundant fans with dedicated GPU airflow design ensure continuous operation in mission-critical environments. Supermicro's integrated IPMI 2.0 BMC with KVM-over-IP and virtual media support provides secure remote management, while AMI UEFI BIOS with Secure Boot underpins system integrity. The platform supports Windows Server, Red Hat Enterprise Linux, Ubuntu, and VMware vSphere, meeting diverse enterprise operating system requirements.
