Availability Management - A Guide to Planning and Implementing Cross-Site Mirroring on System i5

In this IBM Redbook, we introduce the concept of cross-site mirroring as implemented in OS/400 or i5/OS at V5R3M0. Cross-site mirroring (XSM) describes the replication of data at multiple sites. This involves the use of clustering, cluster resource groups (CRGs), independent auxiliary storage pools (IASPs), and other components. A sub-function of cross-site mirroring is geographic mirroring, which describes the storage management replication function of cross-site mirroring. An additional component of this highly available technology is the Geographic mirroring function that keeps two identical copies of an independent disk pool at two sites to provide high availability and disaster recovery. These sites may be geographically close to one another or far apart, depending on the needs of the business. This Redbook is aimed at IBM, IBM Business Partners, and customers who are considering, planning, and implementing a highly available solution on System i5.
