Principles:
First choice: cascading onboard back-end ports. Second choice: configuring hot-swappable
back-end modules.
Each back-end port first conducts level-one cascading, then considers level-two. When the
level-one cascading is fully loaded, use level-two .
Advantages:
Access of multiple front-end hosts + Expansion of
multiple back-end disk slots

Модули ввода-вывода
8/16/32 Gbit/s Fibre Channel and 10GE/25GE ALL-IN-ONE
A 4-port interface module for multiple protocols that only requires optical module
replacement.
TCP/IP Offload Engine
The Hi1822 chip developed by HiSilicon supports the TOE function. Processing the
TCP/IP protocol is offloaded from the CPU to reduce the I/O processing latency by
10%.
FastWrite
FastWrite reduces the four handshakes of the transmission protocol to two, improving
transmission efficiency and performance by 10%+ in long-distance transmission (such
as active-active).
