看完这篇文章后面的评论，才比较清楚的了解了 OpenSolaris? 的许可问题，原来是彻头彻尾的反 GNU 的。
如果说要停止开发的话，也可以理解，开源社区的人们应该额手相庆了。这个评论是这样写的：

Operation System or Operating system ?
2010-07-18 15:53 
老徐 新来的实习生，把 Operating System 写成了 Operation System ，怎么看都觉得有点别扭。他说是字典上查询来的，绝对不会有错。刚才去了一把? Wikipedia ，搜索 Operation System 自动定向到 Operating System 了。
或许这个实习生没有说错，但是作为计算机应用专业的硕士，这个词应该是放在口头上的，就像自己写一个不常用的中文字，看来看去不顺眼，估计是有那里写错，但是找不出错的地方。
这位小兄弟，还把 Leadership 写成了 leadship 。? 
数据中心设计的五大趋势
2010-07-18 15:42 老徐 低碳，绿色的数据中心必将是趋势。这篇文章介绍了数据中心的五大趋势，对于企业的 IT 运营和 IT 服务提供商都具有借鉴价值。
1. Energy costs outweigh capital costs
2. Modularity matters
3. Cooling is key
4. Virtualized everything
5. Self-diagnosing data centers
云计算改变世界最早的报纸发行商
2010-07-18 15:37 老徐 看完这篇报道，会对 “IT Doesn’t Matter” 有更加深的感触。 每一个 IT 人都应该很清楚自己的角色。当 CEO? 削减成本的大斧砍下的时候，由规模化提供服务的 SaaS 模式必将盛行。
从以前的 ASP (Application Service Provider) 到 SaaS，标准化和规模经济导致的低成本，将是云计算大展前途的地方。

ZT: Ethernet Bonding (Linux)
2010-04-11 12:03 老徐 Ethernet Bonding (Linux)
Bonding ethernet channels in Linux is easy. With the right configuration and hardware, it can be done in minutes.
In this example, I have a 4 port intel Gigabit card and I wanted to utilize this and my Network switches LACP/LAG?capability. Lets?assume?we have the Network switch part already configured to have its ports utilize LACP/LAG.
On the RHEL 4.3 server that is hosting my samba file server below are the steps outlined to configure ethernet channel bonding/teaming on the RHEL 4.3 server.
Edit the?/etc/modprobe.conf file and add the bonding kernel module and its mode.
# vi?/etc/modprobe.conf
#regular network card (built-in)
alias eth0 e1000
alias eth1 e1000
#the bond interface
alias bond0 bonding
#bond interface mode.?mode=4 (802.3ad/link aggregation)
options bond0 mode=4 miimon=100
#Intel 4 port Gigabit ethernet card
alias eth5 e1000
alias eth3 e1000
alias eth4 e1000
alias eth2 e1000
alias scsi_hostadapter ahci
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
Now make sure to edit the /etc/sysconfig/network-scripts/ifcfg-ethX (where X are the ethernet ports that will be part of the bond0 LACP interface)
# vi /etc/sysconfig/network-scripts/ifcfg-eth2
DEVICE=eth2
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
TYPE=Ethernet
Now we don’t want to edit every single file as its a boring and error prone process
# for i in {3..5} ; do cp /etc/sysconfig/network-scripts/ifcfg-eth2 /etc/sysconfig/network-scripts/ifcfg-eth$i ; done
#for i in {3..5} ; do sed -i “s/DEVICE=eth2/DEVICE=eth$i/g” /etc/sysconfig/network-scripts/ifcfg-eth$i ; done
Now create the bond0 interface configuration file.
# vi /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
IPADDR=192.168.1.30
NETWORK=192.168.1.0
NETMASK=255.255.255.0
USERCTL=no
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
Load the bonding kernel module.
#?modprobe bonding
Now bring up the bond0 interface
# ifup bond0
Verify the bond0 interface
# cat /proc/net/bonding/bond0

You can now try transferring files to/from the samba servers shared folders, once the transfer process is on-going, try unplugging the network cables that are part of the bond/LACP/LAG on the Network switch or on the configured 4 port Intel ethernet card.
