    That is normal, you can safely ignore it.

    If you only have one file system (/) you don't need any partitions on your /dev/md0. So don't worry about it.

    Thanks boss!!

    This is server i5, but its not like i5.. how can i check this is i5 server or not?

    Because quad core i used on another server..that is very fine and good..

    Is this low from quad to i5?

    You rarely see filesystems or partition tables directly on an md device. Typically, it goes:

    sdxy & sdxz form md0.
    md0 is an lvm physical volume and a member of a volume group (vg00).
    vg00 contains logical volumes (/, swap, /home, blah)

    A bit of an odd config.
