Exam Tips:
- Supports POSIX
- HPC, ML, Big Data = Lustre
- Metadata stored on Metadata Targets (MST)
- Objects are stored on object storage targets (OSTs) (1.17TiB)
- Baseline performance based on size.
- Size - min 1.2TiB then increments of 2.4TiB.
- For Scratch - Base 200 MB/s per TiB of storage.
- Persistent offers of 50 MB/s, 100 MB/s, and 200 MB/s per TIB of storage.
- Burst up to 1300 MB/s per TiB (Credit System).
- Deployment Types:
- Scratch:
- Pure performance
- Short term of temp workloads.
- No HA
- No Replication
- Persistent:
- Has replication with one AZ only
- Backup to S3 (Manual or automatic 0-35 day retention.)
