This is new setup of windows 2008 server. A storage of more than 2TB being allocated to it, but it only detects it as 2.0TB although the exact space is 2.7Tb. How to make w2k8 identify it?

The disk must be converted to GPT.  MBR disks have a 2TB limit.  You will not be able to do this if this is your boot disk (unless 2008x64 is installed on an EFI-enabled system).

HI PowerEdge Tech,

That's mean the problem is on MBR of the boot disk? BTW, how to make 2008x64 is installed on an EFI-enabled system?

It is not a "problem" with it ... just a limitation of any MBR disk.  

How many physical disks do you have in the server?
How many "disks" are showing in Disk Management?
What RAID configuration are they in ?
What system do you have?  
What RAID controller are you using?

You will have to check the specs for your server to see if it is EFI-capable.  This will involve a reinstall of Windows.

I'm using IBM blade HS22, and think this blade is efi- capable. My w2k8 64bit is setup, and in the disk management, I can see the 2.7tb shared space is allocated. When I want to create a partition, a popup box shown, and present a choice - convert to gpt. Does it means that I can use the whole 2.7tb?

If this is a "data" volume then, yes, you can convert it with no problems.  If this is the same disk where Windows installed though, then you can't convert the boot disk to GPT unless your system is not only EFI-capable, but enabled.
