Explanation:
A:Replication options:
*One-to-One Mirroring: This is the most straightforward and popular approach to mirroring.
Thereare one Master system and one Target system in this configuration and is described above.
*Many-to-One Mirroring:
In Many-to-One mirroring, several Master systems are mirrored to a single Mirror target. ManytoOne mirroring is frequently used by customers for Disaster Recovery purposes, to collect exact
duplicates of multiple systems at multiple remote locations at a single, central site, where
recovery scenarios can be centrally managed.
*Bi-directional Mirroring:
Bi-directional Mirroring refers to the ability for systems at sister locations to mirror to each other.
For instance, a system in Los Angeles may be configured to mirror its volumes to a sister system
in Houston, which in turn and simultaneously mirrors its volumes to the Los Angeles system. In
the event either site experiences a problem, the data is readily available at the sister site.
*One-to-Many Mirroring
In One-to-Many mirroring, a single Master system is mirrored to multiple targets. This isfrequently used to distribute data to multiple sites (i.e. remote offices of large corporations), or to
setup several recovery points for disaster situations.
D:The Sun Storage 7000 Remote Replication can be used to create a copy of a project (group of
filesystems, LUNs) from any Storage 7000 System (source) to another 7000 system (target) at a
remotelocation through an interconnecting TCP/IP network that is responsible for propagating the
data betweenthem.
