Who's Afraid of IASPs?
Three Benefits of IASP Technology
IASPs support your IFS and library file systems. Traditionally, the library structure is where OS/400 files and programs reside. Now, after 7.1, virtually all objects can exist in IASPs. However, the *SYSBAS ASP, which holds the OS and some other objects, still must reside in the system's base pool, or System ASP 1. (If you run 6.1 or 5.4, more objects will have to stay in *SYSBAS ASP.) Moreover, all customer data, apart from user profiles and some configuration objects, can be stored in an IASP. To learn more, scan the IBM Information Center for documentation.
IASPs can be used as a directory system. IBM and its vendors have used it to host non-traditional applications like Domino, SAP, EnterpriseOne, UNIX, and more. By using this technology for an HA environment instead of software replication, you can replicate/split the disk on demand or spin it up with very little downtime—not to mention less day-to-day maintenance.
In addition to supporting IASPs, Robot products are designed to enhance it. Robot Schedule makes running your business applications through IASPs easier and can itself be installed and run in an IASP. Robot Space tracks IASP space usage patterns and more.
