DGXC Cluster IP address must be non-conflicting with existing NVIDIA private IP space. | Req ID | Test Details [(Legend)](/dsx/ncp/nvidia-requirements-for-ai-clouds/appendix#test-legend) | Requirement Area | Description | | :-------- | :--------------------------------------------------------------------------------------- | :------------------------------------------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **NET03** | add | Non-Conflicting IP Space Allocation for the DGXC Cluster | **Bring Your Own IP (BYOIP):** NCP shall support the ability for NVIDIA to bring and allocate its own IP private address space for DGXC GPU clusters. **Stable IP**: NCP shall provide a possibility to create static IP allocations that persist across instance restarts and re-creations. That includes floating IP allocations. **DoD space:** NCP shall support allocation and use of the 7.0.0.0/8 IPv4 address space for DGXC GPU cluster deployments. This IP space shall be considered equivalent to RFC1918 addresses **Routing Support:** NCP must support advertising and routing of BYOIP prefixes within the NCP environment and across interconnects (Private Cloud Interconnect, IPSec, etc.) | #### Connection to NVIDIA CorpIT Network **Purpose:**\ Provide connection from DGXC GPU clusters within NCP to NVIDIA CorpIT for internal Command & Control and admin access. | Req ID | Test Details [(Legend)](/dsx/ncp/nvidia-requirements-for-ai-clouds/appendix#test-legend) | Requirement Area | Description | | :-------- | :--------------------------------------------------------------------------------------- | :---------------------------------- | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **NET04** | INFO | Connection to NVIDIA CorpIT Network | **Bandwidth**: Low bandwidth (Up to 10Gbps). **Transport**: Private Cloud interconnect + VIF + BGP (preferred for better performance/security). DGXC will establish connectivity to NCP through a mutually agreed Point of Presence (POP) using Private Cloud Interconnect, functionally equivalent to AWS Direct Connect, GCP Dedicated Interconnect, Azure ExpressRoute, and OCI FastConnect. Connectivity will be provisioned with a Virtual Interface (VIF) and routing established via BGP. The interconnect will be used to exchange private IP space (RFC1918, as well as 7.0.0.0/8) between DGXC and NCP. | ![Corporate network connectivity diagram](https://files.buildwithfern.com/nvidia-dsx.docs.buildwithfern.com/dsx/e7322e7d82e5937f2a765bd5e0508182c5f9e243dfe061efed6860d55b44b667/_dot_dot_/docs/ncp/nvidia-requirements-for-ai-clouds/assets/images/nrac-corpnet-connectivity.png) Figure: Private Cloud interconnect + VIF + BGP for CorpIT access #### Connection to DGXC Storage **Purpose:**\ Enable high-bandwidth, end to end MACsec-encrypted (fail-closed) access between the DGXC GPU clusters within NCP and NVIDIA DGXC on-premises object storage for large-scale data movement. | Req ID | Test Details [(Legend)](/dsx/ncp/nvidia-requirements-for-ai-clouds/appendix#test-legend) | Requirement Area | Description | | :-------- | :--------------------------------------------------------------------------------------- | :------------------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **NET05** | INFO | Connection to DGXC Storage | **Transport**: Private Cloud interconnect + VIF + BGP (preferred for better performance/security).

These persistent IP addresses must be used exclusively for DGXC traffic and shall not be shared with or carry traffic from other NCP tenants. **Availability:** Must support redundant upstream paths to ensure connectivity under failure. | ![Internet access diagram](https://files.buildwithfern.com/nvidia-dsx.docs.buildwithfern.com/dsx/d7d229f4a7197a319251575483a0b8c7a441987f3d9b809a2f0f7eb099b3e9ae/_dot_dot_/docs/ncp/nvidia-requirements-for-ai-clouds/assets/images/nrac-internet-access.png)\ Figure: Public internet for DGXC hosted Services access
