Storage Hardware and Software Trends
2
• Lack of organic support for leveraging in-storage compute for
I/O and data processing operations and reducing I/O overheads
• Hardware trend: fast microseconds latency devices with
increasing in-storage compute capabilities
• Software trend: fast user-level file systems to bypass the OS for
reducing software overheads (“boundary crossing”)
• Unfortunately, dominating I/O overheads like data copy, system
calls, PCI communication costs remain
