PowerHA for SMB

I’ve heard many clients state that PowerHA is too complex or expensive for the small-to-medium IBM i environments, so this week, Steve Finnes is here on ‘i Can’ to answer a few questions.

Leveraging SSDs and IASPs with BRMS Migration

One significant change in IBM i 7.2 is the modernization of storage tiering in the BRMS migration function. In prior releases, the migration function in BRMS works only for library migration between auxiliary storage pools (ASPs) based on the specified policies for frequency of use. However, in IBM i 7.2 with PTF SI57831 applied, the BRMS migration function is enhanced to support the migration to independent ASPs (IASPs), migration of *LNK lists for IFS files, and migration of database files to different SSD and HDD storage tiers within the same ASP.

Tracking IBM i System Limits, Part 2

My last blog was an Introduction to IBM i System Limits and Maximum Capacities. In that blog, I introduced System Health Services, which allow you to track system limits. System limits tracking support is provided via Db2 PTFs, so be sure to install the latest Db2 Group PTF when you start to explore this capability. The limits tracked vary by release and Db2 Group PTF level.

How to Back Up IFS Objects on Systems With IASPs

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.

A Low-Cost External Storage Configuration With IBM i

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.
