In IBM Cloud Pak for Integration (CP4I) v2021.2, App Connect Enterprise (ACE) Dashboard requires persistent storage to maintain configurations, logs, and runtime data. The supported storage type for the ACE Dashboard instance is file storage because:
It supports ReadWriteMany (RWX) access mode, allowing multiple pods to access shared data.
It ensures data persistence across restarts and upgrades, which is essential for managing ACE integrations.
It is compatible with NFS, IBM Spectrum Scale, and OpenShift Container Storage (OCS), all of which provide file system-based storage.
A. Ephemeral storage – Incorrect
Ephemeral storage is temporary and data is lost when the pod restarts or gets rescheduled.
ACE Dashboard needs persistent storage to retain configuration and logs.
B. Flash storage – Incorrect
Flash storage refers to SSD-based storage and is not specifically required for the ACE Dashboard.
While flash storage can be used for better performance, ACE requires file-based persistence, which is different from flash storage.
D. Raw block storage – Incorrect
Block storage is low-level storage that is used for databases and applications requiring high-performance IOPS.
ACE Dashboard needs a shared file system, which block storage does not provide.
