This whitepaper examines some common practices in enterprise storage array design and discusses opportunities for improving enterprise storage strategy by thinking with random I/O rather than sequential.
A good enterprise storage array attempts to sequentialise the workload seen by the hard drives, regardless of the native data pattern at the host level.
A single Solid State Drive (SSD) is capable of random I/O that would require hundreds of hard drives to match. However, obtaining this performance from an SSD is challenging.
A new class of enterprise data storage system doesn’t substitute flash, but engineers an entirely new array to unlock flash’s full performance potential and deliver array-based capabilities
