With all the industry news and talk about how to manage big data, I wanted to write a follow-up to my post on IASPs last week. If you are using IASPs, how are you managing the growth and ownership of that data? How are you alerted when you get close to exceeding your thresholds?
Because they are lowering the cost of storing data on IBM i, external disk units will, over time, result in all of us keeping more data. As a result, the importance of tracking IASP data will also grow.
Unfortunately, many tools for tracking disk consumption don’t work with IASPs. RTVDSKINF does collect IASP data, but it generates reports, and you are responsible for maintaining and graphing its results.
As an administrator, you don’t have that kind of time—especially if you have to write scripts to analyze data—so Robot Space does the work for you, maintaining and making visible (in lists or graphs) the collected results on the day or the week.
To help you keep proactive, Robot Space warns you if you get close to exceeding thresholds. And in addition to tracking our objects, it can identify common ones for duplication and even clean up redundancies left over from development or other administrators.
With this explosion in disk space consumption, you can’t ignore this area as you evolve to PowerHA or IASP technology.
