We are using VPLEX as part of a corporate-wide high availability strategy providing us with a means to achieve data center and storage failover for all of our corporate production application and files. We are running this between two data centers creating a distanced RAID and creating a more robust infrastructure and ensuring business continuity.
- High Availability
- Fail Over
- Business continuity
- Requires high bandwidth low latency connectivity between sites.
- Cost wise it is expensive because you have to purchase with a mirror in mind.
- Configuration can be difficult.
This works in two fold. First it creates a copy of the data in two locations, protecting the data from a SAN or a NAS failure. Second, it provides a data point in a second location that can be used as storage for a stretched virtual cluster, giving a virtual stack a means to continue operation.
