Copy Services: Multiple Cluster Mirroring

SVC (B)

What this is► Multiple Cluster Mirroring enables Metro Mirror and

Global Mirror relationships to exist between a maximum of four SVC clusters

► A VDisk can be in only one MM/GM relationship

► One example is shown in the figure (B to A, C to A, D to A) , but other configurations (like triangle-shaped or square-shaped) are also supported

► Both Metro Mirror and Global Mirror are supported within the same overall configuration (for example B to A as Metro Mirror, and D to A as Global Mirror)

► The SVC clusters may take advantage of the maximum number of remote mirror relationships

Why it matters► Enables customers to copy from several remote sites to a single

SVC cluster at a disaster recovery site

► Supports implementation of consolidated DR strategies

► Helps customers who are moving or consolidating data centers

Copy Services: Increase number of MM/GM relationships

What this is►Creation of up to 8192 Metro Mirror and/or

Global Mirror relationships ►Relationships individually controllable

(create/delete, start/stop)

Why it matters► Improves scalability for increased data protection in

remote copy operations

► Increases the remote copy scope when using Multiple Cluster Mirroring

Copy Services: Multi-Target Reverse FlashCopyWhat this is

► Enables FlashCopy targets to become restore points for the source without breaking the FlashCopy relationship and without having to wait for the original copy operation to complete

► Supports multiple targets and thus multiple rollback points

POINT IN TIME

Why it matters► A key advantage of the SVC Multi-Target

Reverse FlashCopy function is that the reverse does not destroy the original target; thus anything using the target, such as a tape backup process, will not be disrupted; multiple different recovery points can be tested

► SVC is also unique in that an optional copy of the source VDisk can be made before starting the reverse copy operation in order to diagnose problems

Cluster: iSCSI – Host/HBA

What this is► Native attachment to SVC for host

systems using iSCSI HBAs► Not used for storage attachment, which

remains connected through Fibre Channel

► Not used for cluster-to-cluster communication, nor for communication between SVC engines in a cluster

Why it matters► Enables customers to connect host

systems to SVC using lower-cost IP networks
