Can virtual I/O eliminate an entire hardware layer from a data center architecture to save cost and simultaneously increase performance?
An IT manager I met with last week thinks so.
This New York-based IT manager is evaluating virtual I/O to solve a server failover problem – an issue for which I/O virtualization does not seem particularly relevant. However, it turns out that for him virtual I/O can indeed provide a dramatically better solution.
Here’s the basic problem. His datacenter has a number of servers that process transactions submitted by groups of clients. Different servers handle requests from different client groups.
When a server fails, clients must be re-assigned to other servers. They must either be moved to a spare server, or moved to another active server. Either way, the move must be fast and must remain transparent to the clients.
