No GUI Boot Screen Splash

What The No Gui Boot Tweak Does :

This tweak disables the display of the bitmap animation on startup.

 

                                  When the Windows 7 operating system is booting up, it displays to the user an animated graphical Windows logo.  Loading and displaying this logo adds a few seconds to the Windows 7 startup time, so disabling it will shave off these seconds.  The downside?  The screen is black while Windows loads, and if users are uncomfortable with that, then it is not a good idea to disable it.

                                   The logo really has no added value or benefit to display other than letting the user know Windows is loading.  If you have tweaked your system to a comfortable level, and you are comfortable not seeing this image anymore, then it is safe to disable.  Personally, it was tougher for me on Windows 7 than their other operating system, mostly because the Windows load GUI was more fun to look at than it’s predecessors.

Disable The Logo GUI Boot On Windows 7 Startup:

---

1. Select the Windows ‘Start’ button.
2. In the search box, type ‘msconfig’.
3. Scroll up and right click on the program.
4. Select ‘Run As Administrator’.
5. When the system configuration utility is loaded, select the ‘Boot’ tab.
6. Check the box titled ‘No GUI Boot’ at the bottom center of the form.
7. Click ‘Apply’.
8. Select ‘Ok’.
9. Restart your computer.

 

Hyper-V

Installing the Hyper-V Role

Now, log in using an account with local administrative privileges, and then open the Server manager. In case you aren’t familiar with the Server Manager, it’s the new tool that acts as a centralized management utility for Windows Server 2008. You can access it by entering the ServerManager.msc command at the server’s Run prompt.

When Server Manager opens, right click on the Roles container, and then choose the Add Roles command from the resulting shortcut menu. Windows will now launch the Add Roles Wizard.

You must choose the Hyper-V Role.

At this point, you will see the screen that’s shown in Figure B. Basically, this screen just tells you that you may end up needing to enable virtualization at the BIOS level prior to installing the Hyper-V roll. Some servers require this, and others don’t. The screen also tells you that after installation is complete, you can use the Hyper-V Manager to create and configure your virtual machines. The serene also contains a few links that you can use to access more information about the Hyper-V role.

This screen allows you to access more information about the role that you are installing.

Click Next, and you will be taken to a screen similar to the one that’s shown in Figure C. As you can see in the figure, your virtual machines require virtual networks in order for them to be able to communicate with other network hosts. Essentially, this screen allows you to choose the physical network adapter that you want to bind the virtual network adapter to.

You must bind the virtual network adapter to at least one physical network adapter.

You have the option of choosing multiple network adapters for load balancing, but you also have the option of using a single physical network adapter for all of your virtual machines. When you have made your selection, click Next.

You should now see a screen confirming that you are about to install the Hyper-V role, and warning you that the server may require a reboot after installing the role. Now, just click the Install button to install the role. The actual amount of time that it takes to install the role varies depending on your server’s performance, but the entire process took about 20 seconds on my server.

When the installation process completes, click the Close button, and then click Yes when you are prompted to reboot the server.  When the server reboots, log back into the server and the Server Manager should automatically load and resume the installation process. After about a minute, you should see a message telling you that Hyper-V has installed successfully. Click Close to complete the wizard.

Terminal services

Terminal services manager and Windows 7

I just found out that Terminal services manager does not exist in Windows 7. But fear not, the Remote Desktop Services Manager will do the trick. It is included in the Remote Server Administration Tools for Windows 7, which can be downloaded from here.

After some serious googling, I was also able to figure out how to actually enable the feature, in "Programs and Features", "Turn Windows Features on or off":

Go to "Remote Server Administation Tools", "Role Administration Tools", and enable "Remote Desktop Services Tools".

 There! Now you'll find the Remote Desktop Services Manager in your start menu — and can start kicking out stale remote desktop connections from your servers. :) 

RAID

RAID 

                          Redundant Array of Independent Disks is a redundant system uses multiple Hard Drive to store your data,so if one drive is fail your data is safe and accessible.

Mirroring – Multiple disk containing identical data

Striping - sequential blocks of data are split among multiple disk

Fault-tolerant – This is where parity data is stored allowing data to be recovered if a problem is detected

RAID 0

                      This configuration is the fastest of all the RAID levels, it uses a technique called data striping (see below) and requires at least 2 hard disks.

RAID 1

           This level uses a pair of hard disks at a time to provide fault tolerance (there is no performance benefit) and requires at least 2 hard disks.

Using a technique called disk mirroring (see below) the same data is written to both disks at a time, so if one hard disk crashes then the same data is available from the remaining hard disk. 

RAID 5

                 Data is striped across the drives in bytes, the parity data for one particular drive is stored on another drive allowing the data to be rebuilt using the parity technique.In the event of a disk failure, the data from the failed disk is reconstructed from parity striped across the remaining disks.

Minimum number of drives required: 3

Usable capacity will be generally be the physical capacity less one drive.

So if u have 4 1TB drives there only 3 TB of usable capacity

 

RAID 6 (double parity)

                RAID 6 is similar to RAID 5 in terms of striping and parity, with the major difference being that RAID 6 can tolerate two disk drives failing.

Minimum number of drives required: 4

Usable capacity will be generally be the physical capacity less two drive.

So if u have 4 1TB drives there only 2 TB of usable capacity

RAID 10

               Initially a pair of drives is mirrored as in RAID 1 and further striped as in RAID 0. Raid 10 is also known as RAID 1+0 .

Minimum number of drives required: 4

Usable capacity will be generally be the physical capacity less two drive.

So if u have 4 1TB drives there only 2 TB of usable capacity

TITAN Supercomputer

TITAN crowned as World's Fastest Supercomputer

Titan Cray XK7 is the latest supercomputer to be deployed at  Oak Ridge National Laboratory 

                                       The hardware comes from Cray.Titan uses 200 cabinets which has 18,688 nodes (4 nodes per blade, 24 blades per cabinet) each containing a 16-core AMD Opteron 6274 CPU with 32 GB of DDR3 ECC memory and an Nvidia Tesla K20X GPU with 6 GB GDDR5 ECC memory.The total computational power of Titan is 17.59 petaflops per second(17 thousand trillion calculations per second).There are a total of 299,008 processor cores and just over 710 TB of RAM.

The initial cost of the upgrade was US$60 million

Storage

 
               System storage is equally impressive: there's a total of 10 petabytes of storage in Titan.ORNL uses 10,000 standard 1TB 7200 RPM 2.5" hard drives. The IO subsystem is capable of pushing around 240GB/s of data






OS & Software




Titan runs the Cray Linux Environment, which is based on SUSE 11.



 
Power Delivery

Total power consumption for Titan should be around 9 megawatts under full load and around 7 megawatts during typical use.

ILO

 ILO virtual commands

 The options to restart a server using the ILO are contained under the virtual power tab.You can do one of four options:

    Momentary press – this is like pressing the power button on your laptop/pc or server, with Windows 2000 and above (if I remember correctly), it should cleanly shut down the operating system

    Press and hold – this is like pressing and holding the power button, it will turn off the computer completely and will not cleanly shut down the server

    Cold boot of the system – this effectively powers off the server and restarts it.

    Reset system – this is the ILO way of rebooting it without cleanly restarting the operating system, if your server has hung and wont respond, this might be the option you select.

God Mode

Activate God Mode

Though the name is quite misleading, the fabled God mode is a neat trick. Invoking it is pretty easy. Create a new folder titled GodMode.{ED7BA470-8E54-465E-825C-99712043E01C} and the folder’s icon will change to resemble a control panel and will contain a plethora of control options.

And you will know I am the Lord when I lay my vengeance upon you.
