Requirement Configuration
performance impacts for the users after failover.
Network
adapters
You must map at least one NIC from the source to one NIC on the
target. If the source has more NICs than the target, some of the source
NICs will not be mapped to the target. Therefore, the IP addresses
associated with those NICs will not be available after failover, unless
you configure the advanced options. If there are more NICs on the
target than the source, the additional NICs will still be available after
failover.
File system
format The source and the target must have the same file system format. For
example, an NTFS volume cannot be sent to a FAT volume.
HAL type and
version
The Windows hardware abstraction layer (HAL) refers to a layer of
software that deals directly with your computer hardware. The HAL
type and version do not have to be identical, but they must be
compatible between the source and the target. If the two are
incompatible, Storage Mirroring Recover will warn you. In that case,
you must upgrade or downgrade the target.
Administrative
shares The Full-Server Failover Manager console must be able to access
administrative shares on the source and the target.
Boot volume
configuration
The target boot volume cannot be a dynamic disk configuration. The
boot volume is the disk volume that contains the Windows operating
system and supporting files. By default, the operating system files are
in the \Windows folder, and the supporting files are in the
\Windows\System32 folder. The boot volume might be the same
volume as the system volume, but that configuration is not required.
System
volume
The target must have the same system volume as the source. The
system volume is the disk volume that contains the hardware-specific
files that are needed to start Windows. The system volume might be
the same volume as the boot volume, but that configuration is not
required.
Logical
volumes
There are no limits to the number of logical volumes, although you are
bound by operating system limits. The source and the target must have
the same number of logical volumes, and the source and the target
must have the same drive letters. For example, if the source has drives
C: and D:, the target cannot have drives D: and E:. In this case, the
target must also have drives C: and D:.
