Achievements in Last Period

There has been no activity on this project this month due to other project activity and also another investigation into service resilience architecture that may provide a better solution to the one being developed here.

The issue we now have is that in order to make SRM work we would need to rearchitect our entire cluster to not present the storage at both sites. Since we are likely to be building a metro-stretch cluster for high availability, this calls into question our strategy of using SRM. The project scope is likely therefore to change without a deployment of a live service and will just report on the issue with a recommendation for further work if we want to use SRM.

​Issues and Risks

• Timescales are affected by the above and milestones have been adjusted as a result though the project is still on track to deliver by the end of July.
• Testing has shown the failover process to be less automated than may be wished and an alternative approach is being looked at.

Next Steps

• Continue testing the new storage configuration to see if it resolves the problem.
• Contact Dell to have it confirmed what we have found.
• Produce an options report for future deployment based on the restrictions we have encountered and if necessary change scope and milestones.
