Optimal Server Room Temperature
My boss asked me today “What is the optimal server room temperature?” My first thought was 65 F. I took a look around the campus and all the server rooms were around 65 F. The temperature around campus only means we are running at 65 F. I took a look on the net and found out my answer was right on. The optimal server room temperature is 60 F to 70 F and not below 50 F also not above 80 F.

People keep asking me "What is cloud computing?" Well to keep it simple cloud computing is a bunch of servers at some location running the service that is requested. 
Let's look at Google for this. A lot of people are submitting request to Google at any given time. Now when I say Google I mean all of Google services--Gmail, Search and so on. Google has a cluster of servers in one geographic location to handle the requests. This cluster shares the load of that geographic location. There may be 1500 or more request coming in to Google at any one time. Google has software designed to split the load.
There are many other types of clouds out there. Some clouds let you host your own servers and other let you store data. The bottom line is a cloud let's the user access endless amounts of resource without having servers at their business or home.
Hope this helps.

Amazon Elastic Compute Cloud (Amazon EC2)
Should you host your server on the Amazon EC2? First you need to know what is Amazon EC2. The Amazon EC2 is a cloud base scalable server solution. Acording to http://aws.amazon.com, “Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. So the questions becomes do I need a scalable solution? Hmm...Power just for the sake of power the Jedi way is not (I know I am bad Yoda).
Amazon Elastic Compute Cloud (Amazon EC2) is a good solution if the company is planning to grow. If you are building a large site and don't have the funds up font to start with, using Ubuntu and scaling out to EC2 is a good plan.

Why is RAID 5 Dead?
A buddy of mine told me how bad RAID 5 was so here it is. Like every technology RAID 5 has been over taken by better technologies. Here are the reasons why:
Disks fail
Disk to fail and when more than two disk fail the array is done for causing hours of wrk getting the system back online and you better have a backup ready.
Disk capacities double
With RAID 5 you lose a lot of disk space. I do not like to give up disk space
Now What?
There are many technologies out today that are better than RAID 5.RAID6 is a bit better but the most common file system people are moving to is ZFS. ZFS gives you many option and right speeds out of this world.

Network Time Protocol (NTP)
Network Time Protocol (NTP) is a protocol that system administrators use to update time on network devices or host on a packed switched network. Clients and servers on the the same network should have the same time because of security and troubleshooting. Time is important in the server world with out it administration would be difficult at best.
How is Network Time Protocol (NTP) Implemented
Normally Network Time Protocol (NTP) is implemented in the operating system (OS) of the network host. Linux and Unix systems use a daemon that runs around the clock and this daemon process is called NTPD. Windows systems 2000 and above have the Windows Time Server. Windows and Linux NTP clients synchronizes with a server regardless of the OS.
How dose Network Time Protocol (NTP) help Troubleshooting
The time on a system helps troubleshooting by setting the time for all the system task and files. For example, log files with an accurate time will give the system administrator a better feeling for what the server is doing. Also, system files being created with the right times can help tremendously. Being able to modify files and system tasks by timestamps can speed up task.
