This article discusses QLogic QL45xxx series 100GbE NICs, with capability to breakout into 2x50GbE or 4x25GbE. It covers the OEM parts, firmware and cross flashing between different models in the series.

The article is split into two main parts: a story, and a guide. The story covers how I get familiar with the cross-flashing process, and the guide aims to provide a precise, step-by-step instruction for cross-flashing QLogic QL45xxx series NICs. The guide is based on the experience gained from the story, and is intended to help others who want to perform similar cross-flashing tasks.

DISCLAIMER: Cross flashing firmware can be risky (and involves soldering the EEPROM chip), and, if done incorrectly, can brick / permanently damage the device (especially when you’re not good at soldering). MAKE REALLY SURE THAT YOU UNDERSTAND THE RISKS, AND I AM NOT RESPONSIBLE FOR ANY DAMAGE THAT MAY OCCUR.

前两天 ylw 给我扔了块板子, 说是不知道谁给的, 是个树莓派类似物, 本来是机顶盒 (好像), 被前主人刷成了 ArmBian, 后来就流转到了 ylw 那里. 到了这里, 没有密码, 没有 sudo, 好像啥也没有…? 但是开机之后会自动进入图形化界面 (自动登录), 所以我们相当于有了一个普通用户的权限.

但是这显然不够, 于是经过了 ~1h 的斗争, 我成功拿到了 root 权限, 以下是一些记录. (本来想去截两张图的, 但是截至写博客的时间, 这个板子)

故逝是这样的… 昨天凌晨调试 SA5212M4 的阴间 BMC 到晚上一点, 困死了, 遂睡觉. 早上起来翻看邮件发现天塌了, Grafana 给我发了 10 封告警邮件. 放在 新系馆 的服务器上面所有服务都崩了. 我 连夜 用手机打开 iDRAC, 进去之后就看到了不幸的消息, Correctable memory error rate exceeded for DIMM_B10. 但是暑假老师们都放假了, 机房值班的老师比较忙, 我也在实习过程中抽不开身去机房. 于是我开始思考一个问题: 我能不能在不物理介入的情况下暂时解决这个问题呢?

前两天试图上线机房里面的两台 R630 服务器, 惊奇地发现这两台的 License 都是 Express, 没有 Remote Console. 那么怎么才能搞到 Enterprise License 呢? 官方已经停止支持了, 买不到了. 打开淘宝, 上面有卖的, 但是总觉得买了会被坑. 遂上网查了查, 得到了一些方法. (侵删)
