-It doesn't work like that.
-What I suggest, instead of play with your existence Raid, just put two new HDD 300GB and make them as Raid 1 mirror, then it will become D: drive and you can move your database or any other folders or file to this drive. This is safest way to upgrade the space.

You can add it to the current array but you would only get 150GB* worth of extra space and the controller would change the RAID level to RAID 5 which is slow, also you need a cache battery to do RAID level migration and array expansion.

If you do want to add 146GB of extra space then open the ACU, select the controller and under "more information" button check the battery count. If it is 0 then buyy a cache battery, if not carry on. Add the drive physically with the server powered on, highlight the array and under tasks select to expand it, you'll get a warning that logical drives with RAID 1+0 will be  migrated to RAID 5. After that's complete which takes several hours you can highlight the logical disk and extend it. Then to extend C: you'll need disk administrator if win 2008 or an offline tool such as gparted.

Much easier as piji says to add two 300GB disks as D+:

*Presumably your current disks are 146GB which means they are SAS, 300GB ones are also SAS, you can't mix SAS and SATA in the same array.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

If you have 2 * 600GB disks I would add them as another array as piji suggested. Expanding arrays is a bit of a waste if the new disks are bigger than the old ones.

You must have a P410i/zero Smart Array controller if all it offers is RAID 0, 1, and 10. You'll have to add a cache module and for performance it would be advisable to have battery/flash backed write cache. Your options are as below, Any of them will enable you to use RAID 5, The flash backed cache keeps the cache contents valid during power-outage indefinitely, the battery backed ones keep cache contents valid for up to 72 hours. No battery/flash as with 462968-B21 and the write cache is disabled so write performance is poor.
