Infinio CEO: It’s VNAS not VSAN. Chuh!
Centralised storage often represents the performance bottleneck of the data centre stack. The storage array sits far away from the application and has to deal with changing I/O from multiple applications. As a result, latency to a busy storage array is high and performance can be unpredictable.
Moving storage closer to the application is a great way to solve the problem. Server side flash is close to the application and can act as a buffer to steady reads and writes to the centralised storage array.
