Today’s SQL Server Challenges
How do I consolidate instances? How do I migrate onto another storage platform? How do I accelerate implementations?

How do I minimize downtime?

What service levels can I promise my customers?

How do I minimize complexity? How do I optimize performance?

Where do I find the resources?

Increasing Application Uptime
Reality: System maintenance or component outages are common, both causing downtime…
1.

AutoStart manages automated application and data restart on an alternate server, either local or remote.
SRDF/A, SRDF/S or RepliStor

2.

AutoStart seamlessly transfers control of application and storage resources to a local or remote facility in the event of an outage. AutoStart provides functionality to assist in automating fail back of services, apps and data.
