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

Intelligent DAE contains 2 cascading boards, each with 4x 100GE ports : 2 for uplink, 2 for downlink.

2x uplink ports : 1 for engine #0, the other for engine #1, thus the intelligent DAE is shared by 2 engines (8 controllers).

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).

DFX

Online hot-swappable and online firmware upgrade
