I've got few questions regarding HDS Snapshot technology in VSP G1000 and i would really appreciate if you guys could help me with answering the following questions:
- When snapshot is created is there any pause in IO?
- Where is the snapshot kept?
- How does HDS manage new writes and when snapshot is deleted is there any impact of the writes being committed?
- Any risk on growth of change blocks?
- How long can the snapshot be kept for?
- How does HDS manage application aware snapshot? Like snapshotting a SQL LUN. Does it cause any impact on the SQL front?
