S3DF Dependencies

• Kubernetes

• SLAC LDAP to authenticate to the vCluster

• Internet connectivity to receive logical replication updates. Access is tied to the SLAC NAT address of 134.79.23.9

• DNS resolution for the SBN address

• Weka storage for Kubernetes. The database uses a persistent volume claim.

Associated Systems

Network

The mpcorb-replica depends on Internet connectivity to receive updates from the MPC Annex. The SLAC IP 134.79.23.9 was shared with the MPC Annex as the NAT addresses used for outbound connectivity with SLAC. If this address changes the MPC Annex will need to be notified.
