WASHINGTON (Reuters) - Pending sales of previously owned U.S. homes
unexpectedly rose in February, a trade group said on Monday, pointing to a
modest pick-up in home sales.
The National Association of Realtors said its Pending Home Sales Index,
based on contracts signed in February, increased 2.1 percent to 90.8.
Economists had expected the index, which leads existing home sales by a
month or two, to fall 1.0 percent after a previously reported 2.8 percent
decline.
"We may not see notable gains in existing-home sales in the near term, but
they're expected to rise 5 to 10 percent this year with the economic
recovery, job creation and excellent affordability conditions providing
confidence to buyers who have been on the sidelines," said NAR chief
economist Lawrence Yun.
Compared to February last year, the index was down 8.2 percent.

想买个二手服务器,在家搞bioinformatics计算。ebay上Dell poweredge R900, 2950;
HP DL380 G7 server 之类。内存100G左右,2或4个 Xeron CPU.不带硬盘大约$300-
500左右。自己装ubuntu.
请问这样的服务器划的来么。是不是噪音比较大,比较耗电。

没参观过贵公司机房?没错就是噪音大耗电,此外没啥缺点。

噪音太大。机器内部空间太小。放在家里,不如Dell workstation。

买了个R620,双E5-2670,256GB内存,4个硬盘槽,少了点,而且是2.5寸,这个不太爽。
idle能耗100瓦,如果不长时间靠近噪音还能接受,放在车库。
2950太老,完全不值得。R710勉强,R720, R620性价比可以。
如果你的bioinformatics计算不用大内存又可以用GPU,强烈推荐使用GPU而不是多核服
务器。一块1070秒杀2xE5-2670这16个core。

一般情况下高频好。
