FAQs

Q: What is the memory configuration for each node?
A: Each node supports 20 DIMM slots (16 standard DDR4 slots plus 4 Intel Optane Persistent Memory slots). Maximum capacity is up to 4TB using DDR4-3200 ECC RDIMMs, or up to 6TB when combining DDR4 with Intel Optane Persistent Memory 200 Series.

Q: How many storage drives can the entire system support?
A: The SYS-620BT-HNC8R supports a total of 12 hot-swap 3.5-inch drive bays (3 per node x 4 nodes) with NVMe, SAS, or SATA compatibility. Additionally, each node has 2x M.2 slots for boot drives or caching, providing flexible storage architecture for hyperconverged deployments.

Q: What networking options are available?
A: Each node features an AIOM (Advanced I/O Module) slot that is OCP 3.0 compliant, allowing flexible installation of 1GbE, 10GbE, 25GbE, or higher-speed network cards. Each node also includes a dedicated RJ45 port for out-of-band IPMI 2.0 management.

Q: Can each node be managed independently?
A: Yes, each node has independent IPMI 2.0 management with dedicated LAN port, providing remote KVM access, virtual media mounting, and health monitoring. Nodes can be hot-swapped for maintenance without impacting the other three nodes in the chassis.

Q: What are the ideal use cases for this BigTwin platform?
A: The SYS-620BT-HNC8R is optimized for hyperconverged infrastructure (HCI), scale-out file storage, container orchestration, and software-defined storage deployments. The high-density 4-node design maximizes compute and storage capacity per rack unit while shared power and cooling reduce operational costs.
