Power架构云小机测试笔记

一、云小机介绍
云小机是IBM与启创卓越推出的虚拟云主机，与常见的阿里、百度、网宿的云主机不同，云小机是基于Power架构的，而传统的云主机几乎都是基于x86架构的。我有幸申请到一台云小机，下面就来测试一下云小机的各方面情况。

二、硬件摸底
首先对云小机配置的物理硬件进行摸底。
1、查看云小机的OS

点击(此处)折叠或打开

# cat /proc/version
Linux version 2.6.32-431.el6.ppc64 (mockbuild@ppc-003.build.bos.redhat.com) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) ) #1 SMP Sun Nov 10 22:17:43 EST 2013

可以看出，OS是RedHat Linux。

# lsb_release -a
LSB Version: :base-4.0-noarch:base-4.0-ppc64:core-4.0-noarch:core-4.0-ppc64:graphics-4.0-noarch:graphics-4.0-ppc64:printing-4.0-noarch:printing-4.0-ppc64
Distributor ID: RedHatEnterpriseServer
Description: Red Hat Enterprise Linux Server release 6.5 (Santiago)
Release: 6.5
Codename: Santiago

可以看出，云小机预装了RedHat 6.5企业版Linux系统。

点击(此处)折叠或打开

# uname -r
2.6.32-431.el6.ppc64
# uname -m
ppc64

可以看出，云小机是基于Power架构的，CPU为64位CPU。

2、查看CPU信息

点击(此处)折叠或打开

# cat /proc/cpuinfo
processor : 0
cpu : POWER7 (architected), altivec supported
clock : 4228.000000MHz
revision : 2.1 (pvr 004a 0201)
......
processor : 7
cpu : POWER7 (architected), altivec supported
clock : 4228.000000MHz
revision : 2.1 (pvr 004a 0201)
timebase : 512000000
platform : pSeries
model : IBM,8246-L2T
machine : CHRP IBM,8246-L2T

可以看出，云小机的逻辑CPU有8个，即8核4GHz。

3、查看内存信息

点击(此处)折叠或打开

# cat /proc/meminfo
MemTotal: 4131712 kB
MemFree: 1226560 kB
......

可以看出，云小机的内存为4GB。

4、查看硬盘信息

点击(此处)折叠或打开

# fdisk -l
Disk /dev/sda: 42.9 GB, 42949672960 bytes
64 heads, 32 sectors/track, 40960 cylinders
......

可以看出，云小机的硬盘空间大约有43GB。

5、查看云小机实时运行情况

点击(此处)折叠或打开

# top
top - 12:10:36 up 13 days, 4:50, 1 user, load average: 0.02, 0.05, 0.04
Tasks: 193 total, 1 running, 192 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.2%us, 0.1%sy, 0.0%ni, 99.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 4131712k total, 2906432k used, 1225280k free, 225600k buffers
Swap: 1048448k total, 0k used, 1048448k free, 2258048k cached

可以看出，CPU基本空闲，内存用了3个G，还剩1个G。

总结：
1）由于云小机是Power架构的，绝大多数Linux工具的RPM包是无法安装的，因为大多数工具提供的RPM包是x86架构的。这种情况下就决定了软件必须通过源码安装。
2）系统是RedHat Linux，且云小机未注册，在使用yum安装工具时会报以下错误。
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
解决方法有两种：
一是注册云小机，让yum可用。
二是更换yum源，替换成CentOS的yum源。
3）Power的生态链很薄弱，网上到处都是x86的内容。
CentOS对Power架构的支持很弱，基本上在官网和国内找不到源和镜像的下载。

6、测试云小机的带宽
# wget downinfo.myhostadmin.net/vnstat-1.10.tar.gz
# tar xzvf vnstat-1.10.tar.gz
# cd vnstat-1.10
# make && make install
一般常用的查看流量命令：
1）查看实时流量
# vnstat -l -i eth0

点击(此处)折叠或打开

Monitoring eth0... (press CTRL-C to stop)
rx: 4 kbit/s 4 p/s tx: 4 kbit/s 4 p/s
eth0 / traffic statistics
rx | tx
--------------------------------------+------------------
bytes 152 KiB | 209 KiB
--------------------------------------+------------------
max 20 kbit/s | 32 kbit/s
average 8.27 kbit/s | 11.37 kbit/s
min 0 kbit/s | 4 kbit/s

max 36 p/s | 18 p/s
average 8 p/s | 7 p/s
min 0 p/s | 1 p/s
--------------------------------------+------------------
time 2.45 minutes

2）查看最近五秒的平均流量
# vnstat –tr –i eth0

点击(此处)折叠或打开

64 packets sampled in 5 seconds
Traffic average for eth0
rx 6.40 kbit/s 5 packets/s
tx 8.00 kbit/s 7 packets/s

二、云小机的性能测试
鉴于以上情况，云小机上最好不要测试那些很占用内存的系统或应用，否则难以得到客观的测试结果。比如MongoDB，它的性能在很大程度上取决于内存的大小，内存有限的情况下，MongoDB的性能难以得到充分的发挥。

1、文件系统I/O基准测试
我选用IOzone工具。
主页：http://www.iozone.org/

下载IOzone
# wget http://www.iozone.org/src/current/iozone-3-430.i386.rpm
安装IOzone
# rpm -ivh iozone-3-430.i386.rpm
Preparing... ########################################### [100%]
package iozone-3-430.i386 is intended for a i386 architecture
此包是为x86主机准备的，在Power架构的云主机上安装不成功。
重新下载IOzone
# wget http://www.iozone.org/src/current/iozone3_430.tar

解压IOzone
# tar xvf iozone3_430.tar
# mv iozone3_430 iozone
# cd iozone/src/current
# make linux

开始测试
# cd /opt/iozone/bin
# ./iozone/src/current/iozone -Rab /home/output.xls
iozone test complete.

云计算和大数据有什么关系？

当大数据遭遇云计算从技术上看，大数据与云计算的关系就像一枚硬币的正反面一样密不可分。大数据必然无法用单台的计算机进行处理，必须采用分布式计算架构。它的特色在于对海量数据的挖掘，但它必须依托云计算的分布式处理、分布式数据库、云存储和虚拟化技术。云计算为什么能盛行呢？在互联网领域应用系统的构建：客户群体是不确定的、系统规模不确定、系统投资不固定、业务应用有很清晰的并行分割特征、数据仓库系统的构建、数据仓库规模可估算、数据仓库的系统投资与业务分析的价值和回报相关、商业智能应用属于整体应用、Saas模式构建数据仓库系统。大数据管理，分布式进行文件系统，如Hadoop、Mapreduce数据分割与访问执行；同时SQL支持，以Hive+HADOOP为代表的SQL界面支持，在大数据技术上用云计算构建下一代数据仓库成为热门话题。从系统需求来看，大数据的架构对系统提出了新的挑战： 1. 集成度更高。一个标准机箱最大限度完成特定任务。 2. 配置更合理、速度更快。存储、控制器、I/O通道、内存、CPU、网络均衡设计，针对数据仓库访问最优设计，比传统类似平台高出一个数量级以上。 3. 整体能耗更低。...

以前总是苹果的各种传闻消息占据各大科技、资讯网站头条，微软就像霜打的茄子一样默默躲在墙角抹泪——想爆料也没什么可拿得出手的。而现在，微软凭借大一统的Windows10疯狂反扑，成为当下的最热点。而其与国内互联网企业推出的免费政策，更是让微软焕发青春。不过微软并未停止激进的步伐，反而“变本加厉”，向安卓设备开始发动攻击。近日，微软与OEM厂商合作，准备在安卓设备预装微软应用。这一方面意味着微软想向OEM厂商献媚，修复彼此之间的裂痕，另一方面还想趁机渗透进更多用户的屏幕世界中，甚至还能借此攻击老对手谷歌，可谓一石三鸟。自此开始，微软开始像一头睡醒的雄狮，展现出枭雄的本色。献媚OEM厂商微软与小伙伴修补裂痕近日，微软宣布将在11家硬件厂商产品中预装微软旗下数款应用，涵盖Office系列、OneDrive以及Skype等办公、云存储和通讯领域在内的应用。可以说，微软具有生产力的应用几乎全部上阵。而且这次合作不单单是那些名不见经传的小厂商，还有许多重磅企业参与其中。如三星最新的旗舰机型、戴尔所生产的安卓设备等。此外，加拿大Hipstreet和俄罗斯DEX公司等在部分国家有一定规模的硬件厂商...
