Expanding RAID1

Majority of time I build RAID5 configuration however a client is requesting a RAID1 for SBS2011 and costs are a concern. The server looking at is RAID1 with 4 bays, question what is involved expanding RAID1. Thank you.

There is no expansion of Raid1.  If additional space is needed, would need to add disks and create another RAID.

Well, some controllers can do an online migration from RAID1 to a 3 or 4 disk RAID5; or a RAID1 to a RAID10...

But if they want to expand a RAID1, the simplest way to do this that works with all controllers it to expand by adding a 2nd RAID1, and moving files/applications around to balance the load.

Remmett70 is correct.  In normal situations you would install another set of drives and create a new mirror.

When we are installing SBS 2011 we tend to use 2 x 250 / 500GB drives for the OS and then a pair of 1TB/2TB Drives for the Data.  Obviously every customer is different but that suites about 90% of mine.

What server and controller model are we talking about here?  and what size are the disks?

There is still a way. If you need to expand the size of the RAID1 then you buy new bigger drives and replace the existing pair of smaller size. One at once. Let them remirror and then extend the size in Windows.

Noxcho's idea will not work on most Dell controllers ... your options depend on your configuration.

Works with almost all HP ones though, if you have a battery.
