How important is array level synchronous replication these days?
When I consider all the synchronization techniques being introduced at higher levels in the I/O stack, I wonder if this feature of the new Violin kit is really a differentiating factor that will encourage new customers to go for the kit? Doesn't it just double up the cabling that would be required for a vMotion or Software Defined Storage type of environment?
Perhaps there are specific high performance applications that might benefit from this array-array synchronization, but I'm not sure it is going to boost sales enough to get the firm back into favour with the stock market.
