Default sme server....diff. drive sizes

hey guys, been awhile since i posted here. Hope everyone is well !

i've been playing around with different NAS solutions, and at the moment i have settled on Naslite2-HDD. I'm not totally satisfied with it due to the lack features, specifically the inability to go "live" (securely) when the need arises.

The how-to related to Sme Server specifically states:
Quote:
Please note that if you use more than one hard disk, all hard disks must be identical in size!
My question is, how does the sme-server handle different size drives? what are the consequences of using different size drives? If i use all the same sized drives (160G x 3), do i have 480gigs of storage, or is it 160 gigs mirrored?

Please educate me!

Default It depends on which sme version you have

With Qty-3 160GB drives you will get the following:

SME version 7.0 or earlier sets 3 drives as RAID-5 which means 320 GB of storage (160GB for parity)

SME version 7.1 sets 3 drives with 2 in a RAID-1 mirrored array and 1 hot spare so you have 160 GB of storage.

Quote:
Your server will be automatically configured as follows:
  • 1 Drive - Software RAID 1 (ready to accept a second drive).
  • 2 Drives - Software RAID 1
  • 3-5 Drives - Software RAID 5 (4-5 drives with SME 7.1)
  • 6+ Drives - Software RAID 6
I believe you can use different sized drives but each drive will be formatted the same size as the smallest drive. If you have a 100GB and 2 160GB drives then all must be formatted to 100 GB.
Quote:
With SME 7.0 if you utilize more than one drive, they should all be identical in size and model. From SME 7.1 this is no longer a requirement

thank you for the reply,

so.....if i were to use 3-160 gig drives, and 1-250gig usb drive. Only 160 gigs of the usb drive would be utilized? or does that get treated as a hot spare?

I'm sorry for my ignorance on the subject, i have a hard time grasping the whole raid array, mirrored or not, as well as the different types of raid that can be done........guess i'm off to do some googling

thanks again

I doubt you can use a USB drive.
