1. What is the maximum number of child clones/child
1. What is the maximum number of child clones/child databases can be supported by one parent database PURE snapshot?
1. What happens to performance of the parent and child databases over time? If performance degrades, how is the best way to improve it? Get a new snapshot?
1. Once data updates/inserts/deletes begin on either the parent or the child, the changes begin to accumulate compared to the original snapshot. Is there a limit to the number of changes or size of the accumulated changes (delta) for either the master or the child?
1. Is there a time limit to how long a snapshot will last before a refresh is required?
1. What, if any, are PURE’s recommendations for maximum changes/delta, best practices, number of clone limits per array, etc.?
1. How many snapshots can one PURE array support?
1. What are some of the best practices for running multiple snapshots with multiple PURE arrays? Single arrays?
1. Can we create snapshots on one PURE array and move to another (parent and child on separate arrays)?
1. Is there a size limit to a snapshot?
1. Is there a size limit to a parent database with PURE snapshots?
1. Is there a size limit to a child database with PURE snapshots?
1. Do PURE snapshots have any issues supporting MySQL databases?
1. Are any data types not supported via PURE snapshots?
1. What happens if a PURE array should panic or shutdown? Any impact to the parent or child databases using snapshots?
1. Is it possible for a single parent server snapshot to support child clones on multiple PURE arrays?
1. Is it possible to have multiple parent servers for one child?
1. Can a replicated database living on virtual volumes be a candidate for snapshots? (Ex. could a DR environment be used to create a snapshot for a QA environment)
1. Can you have grandchild databases based on snapshots from a child database which is based on a snapshot from a parent database
1. Are there any other database architectural changes we might want to consider/test as a result of this technology?
1. Would moving our source system’s OS to Linux from Windows change any of the snapshot capabilities? Can we test this?
1. What do we think about the PURE monitoring tool for managing snapshots? Would we need additional tools for proper monitoring?
- Good.
