FAQs

Q: What processor generations does the SYS-621C-TN12R support?
A: The system supports dual 5th and 4th Generation Intel Xeon Scalable processors in Socket E (LGA-4677) configuration, with TDP support up to 270W per processor, providing flexibility for both current and next-generation CPU deployments.

Q: Can I mix NVMe, SAS, and SATA drives in the same system?
A: Yes, all 12 front drive bays support hybrid NVMe/SAS/SATA configurations. You can deploy any combination of 3.5-inch or 2.5-inch drives across these interfaces, allowing for tiered storage architectures that balance performance and capacity needs.

Q: What GPU configurations are supported?
A: The SYS-621C-TN12R supports up to 2 double-width GPUs (such as NVIDIA H100, L40S, or L40) or up to 6 single-width GPUs through its PCIe 5.0 x16 slots. This makes it suitable for AI inference, GPU-accelerated compute, and virtualized graphics workloads.

Q: How does the AIOM networking work?
A: The system includes dual AIOM (OCP 3.0) slots that accept modular networking cards supporting 1GbE, 10GbE, 25GbE, or 100GbE speeds. This allows you to configure networking bandwidth precisely to your requirements without occupying PCIe slots, and swap network cards tool-free as needs evolve.

Q: Is this server suitable for virtualization platforms?
A: Absolutely. The SYS-621C-TN12R is certified compatible with VMware ESXi, Citrix Hypervisor, Microsoft Hyper-V, and KVM. With high memory capacity, flexible storage, and Intel VT-x/VT-d support, it excels in virtualized data center and private cloud deployments.
