How about going through the existing documents and updating them - The "current" Hub technical brief is dated 10/13/2010 and addresses version 5.41. The current NAS doc is dated 1/7/2013 and addresses version 3.60.
The HA technical doc was just refreshed but it still speaks in generalities and addresses what looks to be an 8.2 or 8.3 UIM version. It would be nice if the document took a full 8.51 clean install and provided instruction on specifically what should be done. Especially around EMS and the semi-hidden trillix probes.
Would be nice to have instructions on generating an uptime report - It is surprisingly difficult to generate a list of outages for a server in this product.
Would be good to have a "this is what you need to monitor within UIM itself" document. Along with the how.
Would be good to have a document that addressed applying CCS to the UMP/USM so that it doesn't look so mundane and dated.
Would be good to have a document that addressed coding within UIM similar to what's done at http://www.rosettacode.org/wiki/Rosetta_Code . Pick a couple of the common tasks - create an alarm, create QoS, iterate across all hubs, execute REST call against wasp, etc and provide like solutions in all the languages (LUA, Perl, Java, Python, #net, C, etc.) that do the same thing. Sometimes it is far easier to code by example than have to learn new language.
