WebNX Utah机房E3-1275V5 1TB SSD服务器benchmark

在webhostingtalk上看到webnx 有一款机器在on sale,配置相当不错,而我又是webnx 的超级粉,立马拿下替换了原来旧的机器,新机器的配置如下:

Intel Xeon E3-1275v5 quadcore 3.6ghz
64gb ddr4 ECC ram
1TB Enterprise SSD
/29 5x usable ip's
30Tb over 1gbps
$65 ** limited time until we burn up the stock on hand!

实话实说,这个机器还是非常有新引力的,再加上webnx 100%的SLA 和 super connected network, 真的是非常爽的价格.

我准备用它来做ESXi 新的vCSA 主控. 

在deploy ESXi之前,先来测试一下这台机器的硬件和network.

Supermicro 服务器IPMI 安装CentOS问题

现在大部分的美国服务商都是使用的supermicro 的服务器,supermicro 一般都自带IPMI.

但是在使用Intel 的E3 CPU 的时候,确会出现这样那样的问题。

总体来说,对于E3 的CPU,supermicro 有两个系列, X10 和 X11,分别专门应该E3-V3,v4 和E3-V5,V6的CPU,问题也由此而来

  1. 安装centos 7 的时候,预加载完成以后就直接黑屏,这是因为IPMI 自带的Aspeed 显卡驱动的问题,在选择安装centos 7 的时候,press tab, 在kernel 的启动选项里面append nomodeset 就可以了
  2. 除了黑屏问题,还有显示soft lock up 等等,这个也是显卡的问题,需要在kernel 的启动选项里面append nomodeset
  3. https://serverfault.com/questions/889868/centos-installer-hangs-through-ipmi, 如果出现这个页面中的问题,或者hangs on start login service,又或者hangs on XXXXX zRAM什么的,那么真的无解,只能安装centos 7 比较老的版本,比如说1511
  4. 有些以5结尾的E3 的cpu,比如说E3-1245V3,E3-1275V5等等 自带显卡,那么也会和ipmi 的显卡aspeed 2400/2500 冲突,也需要在kernel 的启动选项里面选择append nomodeset

 

国外网站关于此问题的讨论:

https://unix.stackexchange.com/questions/353896/linux-install-goes-to-blank-screen

supermicro 官方给的解决方案:

https://www.supermicro.org.cn/support/faqs/faq.cfm?faq=30162

Fedora 也遇到了这样的问题:

Debian 9 开启 BBR

Debian 9 和 10 的内核自带了google 开发的 BBR 拥塞算法,我们可以很方便的开启BBR 进行访问加速

开启方法:

echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf
sysctl -p

如果执行之后没有报错,重启一下系统就可以让配置生效.

重启之后,执行如下命令查看内核是否已开启BBR:

sysctl net.ipv4.tcp_available_congestion_control

显示以下即已开启:

root@localhost:~# sysctl net.ipv4.tcp_available_congestion_control
net.ipv4.tcp_available_congestion_control = bbr cubic reno

查看BBR是否启动:

lsmod | grep bbr

显示以下即启动成功:

root@localhost:~# lsmod | grep bbr
tcp_bbr 16384 14

 

修改office365 outlook 的OST文件的位置

outlook中的邮件(除了pop3)都存储在OST文件中,如果你的C盘不够大的话,建议还是放在其他的SSD盘(pop3邮件一般存储在pst文件中)

outlook 的OST文件默认位置是C盘,如果想修改成其他的位置,google了一上午,发现最简单和便捷的办法就是修改注册表. 其他类似于修改profile 的方式太麻烦了

1 彻底关闭outlook 365 或者2016,同时保证OST 文件没有被其他的程序使用.

2 打开注册表,可以在run中输入regedit

3 打开路径: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook, 在右边空白处右击,选择New -> Expandable String Value

4 键名写”ForceOSTPath”, 然后双击这个键,在”Edit String” 中,填写你想要的 文件路径,然后点击“OK”

5 关闭注册表,然后重启电脑即可.

英文版参见: https://www.isumsoft.com/it/change-data-file-pst-ost-location-in-outlook-2016/

Sept 2019 Updated: 我发现添加ForceOSTPath的办法只能应用于exchange/hotmail/outlook/msn的邮箱,对于IMAP 的邮箱不起任何作用。搜索了半天发现了下面两篇文章:

https://social.technet.microsoft.com/Forums/en-US/f8cf7ce8-ca4c-4619-be32-f9f1a4ffa5fe/forceostpath-not-fully-working-bug-office-2016?forum=outlook

How to move IMAP data files

原来从Outlook 2013年开始, IMAP 和 EAS *.ost 使用的是ForcePSTPath, 而不是ForceOSTPath,尽管data file 是以.ost 结尾的!!!

这个需要注意!

 

 

Windows LTSC 2019 各个版本

大家一般都喜欢在工作中部署LTSC 2019,简洁,稳定!

但是很多人在下载LTSC的时候,很容易被各种iso 弄混。其实说白了网上流传的这些iso都是微软发布的,只是不是版本而已,下面一一陈述:

2018年10月3号版本:

这个ISO 也是网上流传的最多的iso,应该是LTSC最早的版本,但是有个关于文件删除的大bug,所以微软很快就在11月发布了新版:

MSDN 和VLSC 虽然名字不一样,但是其实是同一个文件,通过md5 查询验证了这一点.
