接着的那个是硬盘吗？很少看到服务器硬盘就这么露在外面的呀。

硬盘下面是啥，主板么？
不会用这么多主机垒吧
最顶上那个是啥玩意?

这么牛！没完没了的高，集成度很高。

好象应该是很早的照片了吧。看照片，像用的intel559的网卡，昆腾的硬盘，pII级别的单处理器，还用了两根内存。

一层是两台机器，屁股到屁股或脸对脸放的。

每台机器出两根线，应该还有个终端线，kvm之类用的，所以上面的两个大家伙应该只有一个是交换机，另一个应该是kvm。

不会是刀片机吧。

Server hardware and software

[edit] Original hardware
The original hardware (ca. 199 that was used by Google when it was located at Stanford University, included:[5]

Sun Ultra II with dual 200 MHz processors, and 256MB of RAM. This was the main machine for the original Backrub system.
2 x 300 MHz Dual Pentium II Servers donated by Intel, they included 512MB of RAM and 9 x 9GB hard drives between the two. It was on these that the main search ran.
F50 IBM RS/6000 donated by IBM, included 4 processors, 512MB of memory and 8 x 9GB hard drives.
Two additional boxes included 3 x 9GB hard drives and 6 x 4GB hard drives respectively (the original storage for Backrub). These were attached to the Sun Ultra II.
IBM disk expansion box with another 8 x 9GB hard drives donated by IBM.
Homemade disk box which contained 10 x 9GB SCSI hard drives.

[edit] Current hardware
Servers are commodity-class x86 PCs running customized versions of Linux. Indeed, the goal is to purchase CPU generations that offer the best performance per dollar, not absolute performance. Estimates of the power required for over 450,000 servers range upwards of 20 megawatts, which could cost on the order of US$2 million per month in electricity charges.

Specifications:

Upwards of 15,000 servers[4] ranging from a 533 MHz Intel Celeron to a dual 1.4 GHz Intel Pentium III (as of 2003); a 2005 estimate by Paul Strassmann has 200,000 servers,[6] while unspecified sources claimed this number to be upwards of 450,000 in 2006.[1]
One or more 80GB hard disks per server (2003)
2–4 GB of memory per machine (2004)
The exact size and whereabouts of the data centers Google uses are unknown, and official figures remain intentionally vague. In a 2000 estimate, Google's server farm consisted of 6000 processors, 12,000 common IDE disks (2 per machine, and one processor per machine), at four sites: two in Silicon Valley, California and two in Virginia.[7] Each site had an OC-48 (2488 Mbit/s) internet connection and an OC-12 (622 Mbit/s) connection to other Google sites. The connections are eventually routed down to 4 x 1 Gbit/s lines connecting up to 64 racks, each rack holding 80 machines and two ethernet switches. The servers run custom server software called Google Web Server.
