Note:

You can install the Foundation Edition on a target running other server
Windows editions, so you do not have to pay extra for an upgraded Storage
Mirroring Recover license. When the Foundation Edition is installed on a target
running these other server Windows operating systems, the following limitations
will apply. 1) The server will function in a target role only. 2) The target-only
server can only protect a source that is running the Storage Mirroring Recover
Foundation Edition and one of the operating system editions listed for the
Foundation Edition. 3) Full-server failover is the only supported method of
failover.

Microsoft Server Core is supported when you are protecting data workloads or
entire server workloads, but you will be unable to launch the installation
automatically. You can run the setup.exe for your architecture (i386 or x64), or
you can push the installation by performing an

automatic installation

by using

the Enterprise Install Console.

File system—Storage Mirroring Recover supports the same file system format that
Microsoft supports: FAT, FAT32, and NTFS.

System Memory—There are different memory requirements depending on the
operating system you are using. Be sure you have at least the minimum amount of
memory for your environment. You may want to consider having at least the
recommended amount of system memory.
