HP ML 110 G5 server RAID 1 - Is it possible to add a secondary hard disk for more space?

Dear Experts,

This is the setup: HP ML 110 G5 server RAID 1

I have RAID 1 setup in two identical 250 GB hard disk, now the server has 250 GB space with RAID 1 setup.

I need to have a 1 TB hard disk attached to this server for more space, will it work properly or is it possible?

Please advise!

Thank you in advance.

Sure, pop it in and config the new HDD to be a different logical disk.  i.e, usable increases from 250GB RAID1 to   250GB RAID1 + 1 TB non-RAID

If, however, you want to migrate to RAID5, then you will end up with 500GB usable.

.. plus that 500GB will be much slower at writes then what you have now.  If it was me, I would buy a 2nd 1TB, and set up a 2nd RAID1 with it.    Make sure that the disk is qualified for the controller.   Garbage in ==> garbage out.

Thanks for your quick reply!

Someone told me that I could not use the 1 TB with the existing RAID 1, I do not want this to be linked with the RAID 1 (controlled by the existing chip in mother board), can you please confirm I can add this 1 TB with this server model

"HP ML 110 G 5"

Please confirm.
>>> You:: pop it in and config the new HDD to be a different  logical disk.
I am not sure how I should setup this in BIOS for telling the server to treat this outside RAID 1. Please help me do that.

I am not planning to go for the RAID 5.

>>> You::  If it was me, I would buy a 2nd 1TB, and set up a 2nd RAID1 with it.     Make sure that the disk is qualified for the controller.   Garbage in  ==> garbage out.  

Yes, I could do that but the RAID 1 is running for some time and I may have some problem in moving that to 1 TB right?

I think this server support 1 TB RAID anyway I am not sure I understood your last bit.  Garbage in  ==>  garbage out.  

Thanks so much!

You can not make the disk part of a RAID1 set.  You can stick it in the computer so that it is connected to the same RAID controller, and configure it through the HP array manager BIOS as a standalone disk.  It will still be controlled by the controller, but not married to the RAID1 in any way.

The garbage in-out refers to making sure the disk is qualified.  You just can't plug in anything and expect it to work, or even work well.  What is make/model of disk?

Thank you for the confirmation, I will give you the model number as soon as I get the new hard disk (on it's way) I wanted to try another 1 TB (not sure about the model) but I have ordered a new 1 TB for the ML 110. I will update you soon (let me take 2 days for this)

Thank you. You have my points in any case!

Cheers!

thx - for what it is worth, i wrote a somewhat meandering manifesto on good stuff in general for disks, raid, etc. last night.  
There are a few tips there that would be good for you to read.  Comments appreciated
