I don't know what Tier 2 means at Sun but my opinion is that Sun support people have a pretty good grasp on some of the most difficult aspects of storage - volume management. Here are some things that I think storage engineers should know:
- Fibre Channel networking fundamentals. How HBAs, loops and switches communicate - how zoning is applied, how LUN masking is applied.
- Volume management fundamentals, RAID, mirroring
- Backup and recovery fundamentals, media management, automation
- Basic Ethernet/IP networking knowledge
- Basic understanding of file system and database storage functions
- Basic understanding of storage virtualization. (This is almost the same as volume management but with communications differences.)
