Limitations in MSDP Scaleout
MSDP Scaleout has the following limitations:
It is not fully compliant with Federal Information Processing Standards (FIPS).
The internal services MSDP operator, MSDP Controller, and MDS of a MSDP Scaleout are not compliant with FIPS.
MSDP is FIPS compliant. For more information, see the NetBackup Deduplication Guide.
Does not support SELinux.
Supports only NBCA. Does not support ECA.
Node group cross availability zone is not supported for EKS.
Limited node failure tolerance.
Backup and restore can fail if AKS/EKS node fails. If MSDP operator detects the MSDP Scaleout pod failure, it attempts to restart it and perform a repair operation automatically. The repair operation can be delayed if AWS or Azure infrastructure or Kubernetes do not allow the pod to be restarted.
An Azure or AWS EBS volume cannot be attached to two different nodes at the same time. When the node which a volume is attached to fails, MSDP operator cannot run the same pod with the same Azure or AWS EBS volume on another node until the failed node is repaired or deleted by AKS or EKS.
A node auto-repair may take more than 20 minutes to finish. In some cases, it may be necessary to bring the node backup manually.
IPv6 is not supported.
Changes to MSDP Scaleout credential autoDelete, which allows automatic deletion of credential after use, is not supported. The autoDelete value can only be set during initial deployment.
