If an IBM i system has one or more independent auxiliary storage pools (IASPs) available and a Backup, Recovery & Media Services (BRMS) control group with a *LINK backup item for ASP device *ALLAVL is used to save integrated file system (IFS) objects, a single media file will be generated. The media file will contain objects from the system ASP, user ASPs and IASPs. BRMS will produce a saved item for objects in the system ASP and user ASPs and saved items for objects on each of the IASPs. Each of the saved items refer to the same media file.

I want to tell you about a recently announced enhancement to IBM i 7.1 that allows you to natively attach entry-level external storage even to a Power Systems Express Model 710 or 720. Some of the supported configurations do not require a switch. This gives you a low-cost entry point into an external storage configuration that is a building block for some of the newer Power Systems and IBM i technologies, and gives an option for adding additional storage to the Power Systems Express systems that cannot attach an additional I/O drawer.

Last week, as part of the IBM i 7.1 TR6 announcement, we also announced several new enhancements to PowerHA SystemMirror for i. These enhancements will be available by the end of March via PTFs (SI48371, SI48522, and SI48540). All the changes will be available for the 7.1 release in every language currently supported by PowerHA.

The types of storage used by IBM i customers have become as varied as the types of business that run on IBM i. As virtualization becomes more common and clients move into an external storage environment, PowerHA has technologies that integrate the replication capabilities on those external storage servers with IBM i.

Remote Journaling has been available on IBM i for many releases. It provides an efficient way to replicate journal entries from one system to another and is often part of a high availability or disaster recovery solution. As HA and DR have become a high priority in recent years, remote journaling has become more heavily used and multiple enhancements have been made in recent releases.

The work-management team recently made available some changes with PTFs to help control the behavior of job creation for cases when a program may get in a loop submitting jobs. The change made with the PTF is to slow down the creation of new jobs when the system is approaching the limit for the maximum number of jobs (QMAXJOB system value). This support is in the base operating system in 7.1 and later releases.
