Recently I've done some review to few hard disk which configured with hardware RAID related cases, found that most of the hard disk replacement that lead to OS 'crash' is due to the server did gone through ChkDsk, either trigger by user or start automatically.
I do not know why until I found this article with the below statements:

"....Chkdsk is not RAID-aware. Its algorithms only work in the simplest cases. In general, it must be avoided. If chkdsk attempts to repair one or more member disks, the RAID data patterns will be destroyed, usually beyond recovery."

Frankly, I have no idea how true is the abovementioned statements, as I can't find any relevant info from Microsoft site. However, the experiences that I gone through with customer are real. In this moment, I think we should try to avoid running the Chkdsk when there is any hard disk failure (with hardware RAID configuration).

For more info, you may go to the link below:

#2 In "BIOS", you can easily know what is the current BIOS version and the release date.

#3 "Fans" - shows the total amount of fans, and the RPM.

#4 "Firmware" - refers Baseboard Management Controller (BMC) version.

#5 "Intrusions" - If user did open the chassis for certain purpose such as re-seat the PCI components, intrusion alert will triggered. If the chassis cover was not close properly afterwards, the status will become a red 'X'.

#6 "Memory" - is very straight forward, showing the total amount of memory that a server currently have.

#7 "Network" - all about the Network Interface Card (NIC) includes integrated or PCI NIC.

#8 "Ports" - all about USB or parallel port

#9 "Power Supplies" - You can easy access the Power Supply's status from here

#10 "Processors" - if you need to get the Processor spec, you can have it here

#11 "Remote Access" - Due to most of the Dell 11th Gen server is come with iDRAC, so this function is a 'must-have' option from OMSA.

#12 "Slots" - showing info of which type of PCI card occupied the slot 

#13 "Temperature" - Chassis temperature. This will determine the RPM of the System Fan.

#14 "Voltage"

Generally, the new interface is more user-friendly than the previous version. It is highly recommend to have it for your Dell Server for monitoring and troubleshooting if needed.

On and off, I still received calls that customer still request support or escalation to Microsoft for Windows 2000. I remember few weeks ago, a Singaporean request support for this Operating System (OS), even though result from the troubleshooting shows that the issue from the OS but not hardware. Furthermore, his server already out-of-warranty but still requesting the support with the arrogant tone.
