My server has a Intel ESB2 SATA 3.0Gbps Raid Controller installed.
The raid controller keeps rebuilding the drives which is causing the server to continue rebooting. This is a very critical server for us.
It is our file server, which holds all of our data. Can anyone tell what is going on? I have two separate raids. Volume0 is a Raid 1, and Volume2 is a raid 10.
The Raid1 has 2 250gb drives, and the Raid10 has 4 500gb drives.

I need help please!

Highly likely problem is "TLER".  In a nutshell, you are using consumer-class disks that do not have the proper error-recovery firmware. They are unsuitable for this controller.  (Let alone the duty cycle, the problem is that the FIRMWARE itself is tweaked for non-RAID desktop error recovery.  Get a bad block or two, and the disk may go offline trying to recover for longer than the RAID controller is programmed to wait).

The drives are Seagate Barracuda 250gb 7200rpm SATA...These are the drives that were shipped from System Max. Is there anything I can to fix the problem?

Yes & No
1.  Those disks simply are incompatible with the RAID chip.  Intel has docs that verify this, you can go to intel.com, or look at some of my old posts to get links.
2.  Use software-based RAID.  There is no parity, and it will be same speed on writes, but in a perfect world could be 2X faster then reads, with zero overhead!   Software RAID will balance reads on both disks, while your RAID is actually done with a $2.00 chip and drivers anyway.  You really have a "fake-raid" controller.

you'll have to dig my old posts, or find it yourself, but just google +TLER +MATRIX  enterprise desktop disks and you will find lots of supporting info.   Or go to intel matrix website. It is there if you dig.
