High Availability Scenarios | |
|
||
| Time: 14:38 EST/19:38 GMT | News Source: Microsoft | Posted By: Kenneth van Surksum | ||

In general, high availability will lead you to introduce redundancy in your computing environment, so you can tolerate the failure of any single component. The idea is that you will continue to provide the service even if one of the components stops working. To be effective, you need to cover all layers involved, including servers, storage and networks. Because the presentation was focused on WUDSS, I targeted the two main scenarios for that product: File Server and iSCSI Target (using a SQL Server-based application as an example). The flow was to start with a simple scenario with no high availability and end up with a highly available SQL Server and WUDSS iSCSI storage back-end. Also note that details about certain networking and storage technologies are missing in the diagrams. This was done on purpose, so you can picture in your head the technologies commonly used in your specific environment. | ||
