Interface Trends

• Development Focus:
  • Increasing Speed: Enhancing how quickly interfaces allow peripherals and computers to communicate.
  • Wireless Communication: Facilitating wireless communication between peripheral devices and the CPU.
• I/O Consolidation Competition:
  • iSCSI
  • Fibre Channel
  • InfiniBand

Why I/O Consolidation?

• Factors Driving Consolidation:

  • More Powerful CPUs: Multicore and multisocket architectures
  • Server Virtualization: Efficient management of virtual environments
  • High Demand for I/O Bandwidth: Increasing need for data transfer capacity
  • Reduction in Cables and Power: Minimizing physical connections and power consumption
  • Limited Number of Interfaces: Need to optimize and consolidate available interfaces

• Current Competition:

  • SCSI and iSCSI
  • Fibre Channel
  • InfiniBand

SCSI and iSCSIand Fibre Channel are favored due to the popularity of Ethernet.
