Question IBM System x3850 x5 How can i solve this problem?

[clarkvo]

Hello guys
I have a System x3850 x5 from IBM
Now its running with 4 2.5'' SAS RAID 5(300GB per HDD SAS), and there are still 4 empty intetnal storage drives that i didn't use to upgrade my storage
Last week, it became nearly full. So my boss request to upgrade the storage.
So now, this is my problem.
if i use 4 2.5" SAS with 1TB per HDD, so will it run with those 300GB had installed before?
And can i create 2 raids running together?
I have searched many websites on IBM but no results. Please help

What is your RAID card? I have multiple raids setup on my Dell R7425s all on the same card.

My RAID card is ServeRAID M1015. Does it will setup multiple raids? and will it running both 1TB SAS HDD + 300GB SAS HDD together if i install them?

I cannot find anything that says it supports multiple RAIDs at once, but it will do 16 logical volumes. https://lenovopress.com/tips0740-serveraid-m1015
Are you wanting to run the 1TB & 300GB together on the same RAID volume?

Yes. That's what i mean.
I want to run 1TB + 300GB together in the same RAID volume. So will it run?

While it can technically be done, you don't run disks of different sizes in the same RAID volume. Reason is you will be limited on the per disk size to that of the smallest disk. Therefore you would just be wasting 700GB of space on each 1TB drive.

Thanks for your replying to me
All things are running good here now. And i just replaced all 4 SAS HDD drive with 300GB each of them by 1TB. It was a hard time, because of the database, i needed to transfer it to new storage.
