Fungible公司成立5年后
终于在本月透露更多产品细节
关于Fungible的前世今生可参见
如此高大上的产品亮相
一定要找大佬或意向客户来站台
Juniper是老东家必须要给个面子
Samsung作为存储大厂是目标客户
还有一个重量级表态来自中国的Alibaba
“The Fungible DPU addresses critical network bottlenecks in large scale data centers,” said Yi Qun Cai, VP of Cloud Networking Infrastructure, Alibaba. “Its TrueFabric technology enables disaggregation and pooling of all data center resources, delivering outstanding performance and latency characteristics at scale.”
手握软银的投资
坐拥阿里的高端资源
令人颇感意外的是DPU芯片
核心CPU选择MIPS-64而不是ARM
在解释这个选择时答案也仅仅是缘份
very little is uniquely MIPS, but that was the best fit at the time.
到底是预判了今日ARM之乱象
还是对MIPS依然保留最深的技术情怀
抑或是江河日下的MIPS成本更具诱惑力
这个大胆的选择实在看不出是妙招还是臭棋
既然选择了可编程
就避不开P4编程语言的话题
C与P4于Fungible是两个概念
P4不是编程语言，只是配置语言
P4 is a latecomer to this game, OK? It’s putting varnish on some technology that already exists. It’s a language. It’s a configuration language, not a programing language. P4 is not a programing language. So what I distinguish between configurability and programmability is that with programmability, I can specify in exquisite detail what it is that I want to do and how it is I want to do it with, you know, the tiniest forceps I can specify what to do. The what I configurability provides you again in a limited domain and to a limited extent is some flexibility. And that flexibility – with P4 or without P4 – is rather limited. Let’s be clear about that. And it is especially limited for data centric calculations because these calculations require what is called stateful processing.
前戏有些长
因为DPU芯片太专业了
要开山立业
成就一代宗师的芯片
需要听专家的专业分析
大芯片F1和小芯片S1架构一致
大的可集成在存储和AI服务器上
小的就是做网卡可以支持各种卸载
趋势大家都可以看到
但是最后是Pensando的智能网卡
还是Fungible的DPU架构可以笑到最后
且听下回分解！
