考虑给东图集群续命
东图集群4台esxi都是16G，要不要加内存？ 想法：
- mirrors现在需要内存，但ddr3比较老，james想换机器。有一种办法是先给现在的mirrors加内存，换机器的话把内存拆下来给集群 —— 不兼容，集群机器太老了
- mirrors的git服务考虑放到集群上
- 日常使用内存是否紧张？ --- 看来目前不紧张
需要掌握的信息：
-
支持内存的型号，空余的内存条数
- 现有内存型号
- 主板信息
- 现有内存型号
-
shinobu坏掉的时候还有几条内存条是好的，可以直接装（分不清了，要想办法查错
-
集群在机架中摆放的方式不正确，很难拆开，需要办法
既然 nginx，vsftpd，rsync 这些服务需要的内存不太多，mirrors 的 oom 主要是由 git 引起，建议把 git 服务搬到东图集群的虚拟机上。
东图集群的三台 vcenter 现有 24G 左右的空闲内存。现东图集群的内存需求主要包括：
- mirrors 的 git 服务搬过来（16G）
- gitlab 增加内存（4G 增加到 16G）
淘宝上（二手？）DDR2 ECC 内存的价格很便宜（8G 100-150 元），也可以考虑买一些用来增加东图集群的内存。遗憾的是，根据 Alkaid 提供的主板信息，这批机器 6 个内存插槽，每槽最多支持 4G，现在已经插了 4 条 4G，所以最多每台机器加 8G 了。

比 mirrors 更老的内存 😂

建议将这批机器淘汰掉，已经有故障的征兆了.....

这么严重啊，确实应该淘汰掉了。如此看来之前 vcenter 频发的故障也可能是硬件问题所致，不一定是软件 bug。
现在少院 freeshell 集群是否有硬件故障发生？这批机器也挺老的（2009），不过当年少院是作为小超算买的，稳定性可能稍微好些。既然现在 freeshell 处于半死不活的状态，要不要把这批机器作为新的 vcenter 呢？

freeshell 处于半死不活的状态，要不要把这批机器作为新的 vcenter 呢？
可行，短时间内可以一续
现在少院 freeshell 集群是否有硬件故障发生？这批机器也挺老的（2009），不过当年少院是作为小超算买的，稳定性可能稍微好些。
一号结点报过BIOS firmware BUG其它结点还好
迁移vcenter很折腾的，还有一个问题是freeshell的硬盘位（一个机器两个）只认2T空间，多了不认 这个问题是上次想用freeshell拷贝tuna寄来的硬盘时发现的。此外，考虑服役时间、硬件年龄、机房条件，我不认为是个好方案，极有可能花大力气弄好结果撑不住多久。 此外，@gaoyifan 猜你不想踩这个坑了吧，派谁踩呢？ 上次给james发邮件没有问出来有没有要/已经报废的机器，我觉得追问一下？ 认为还是找那种刚退役的机器比较合适。不过想不到什么地方有而且愿意给。
PS：假期在许老师实验室听到他们要买一批新机器跑实验，不知道是本身不够用还是要淘汰旧的。 我们要不要在bbs上发消息（或者其他方式找这种实验室），再用vpn换报废机器？
@Alkaid Freeshell 的硬盘位只支持 2T 啊，这也是太老了……我赞同你的提议，尽量去找一些稍微新一些的来，不要折腾这些老服务器了。
sonnie 很久之前说过图书馆有空闲的退役服务器，要不要去问问？还有科大云，两年前升级到新版的时候也应该退休了一批服务器。上次 james 没有提报废机器，可能是 james 认为买新机器更适合 mirrors 这种比较重要、负载又高的服务，可以再追问一下。我感觉做云计算、高性能计算相关的实验室淘汰下来的机器配置应该是不错的。
Sonnie 上次还跟我闲置刀片、阵列的事情。还说到 Mirrors 机器太旧的话，用图书馆换机器也行。（虽然我说已经要换了，不过当备份或其他服务也好）
只是他忙别的事一直也没捣腾。机器应该是现成的，装系统之类的LUG自己来就好了吧。
@Alkaid-Benetnash 之前去配置新mirrors时，james提到下学期可以给我们换一些新服务器。他说旧服务器太不节能了，网络信息中心缺电.......
收到，再开学发邮件联系（现在都放假回家了吧）。 网络中心除了mirrors也没有我们其他物理机啊？是要换旧mirrors？ 东图的机器也费电，希望sonnie下学期开学不忙。
这些机器还能开机？
实际情况是，2019 年暑假我接手的时候已经坏了一个了，2021 年 3 月又坏了一个。这几年间 yifan 学长和 sonnie 老师陆续送了我们几台淘汰的机器（但都不算太旧），我们有了足够多和足够好的替代品，所以到了 2023 年 7 月，我们就把剩下两台没坏的机器也一起处理掉了（其实它们还能开机）。

看起来二手服务器的稳定性比想象的好，我们的 AI serving cluster 也是用一些二手服务器和 4090 搭的，虽然我们的几台二手服务器还没坏过，我还总是担心这些服务器不够稳定，毕竟比新机器便宜太多了。
