Zachary, Doing things correctly should be defined more clear as there are many different players with different interests in this game. There is: 1/ Your business goals with the internal business sponsor. This is the where the ROI/TCO must be done. The BIA Business Impact Analyses at this area will make the requirements for the Confidentiality Integrity Availability (CIA) classifications that will lead to the IT implementations and specifications of the SAS installation. This is the theoretical approach, you have started with an installation and now trying to correct what is done to now known specifications. 2/ There is some in house IT department that is delivering IT that as some service (desktops applications Windows servers AD etc). These guys are important as when you are not aligned with them you will come into nasty troubles in the short or long term. The bad start is the were not involved from the beginning. The good is they have let you do al lot on you own and you someone talking their language. The common misalignment between IT departments and business is these days temporary overruled by the devops strategy. I don not know what your position is in your organization just make your plan with that. 3/ External suppliers like SAS or a fulltime external admin. They are commonly not aligned with your business goals they have their own. Let me start with your Installation verification (renewal updates/fixes) and a DR machine. There should be something noted about that in you contract with SAS when it is machine based. When it is user based that could be little bit different. You will need 2 other machines from your internal IT department for that. The DR can be a cold standby, the Inst/verify machine must be up and running continuously as long as you are working on that. According to European law http://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32009L0024&from=EN (article 6) there should be no need for additional costly sas licenses for those additional machines. You need to mention those to sas. It can be sas is claiming following those laws is illegal and wanted to be paid for those. There is your fist challenge to get tackled. Having those additional machines you have to achieve: a/ operational machine -> DR -machine (image to be copied) will that run in your business DR policies Question: what about the more easy backup/restore issues? b/ installation/verification -> operational machine (image to be copied fall-back scenario to be verified). Question: would you think a redeploy of an image or a manually build new system by instructions (sdw) is the way to go? The other is your performance and hardware design setup question. You have seen that SAS is very IO intensive. The best thing is to optimize that IO. That is using internal hardware like SSD's top be used for SASWORK and having all data local on that machine. As network connections are always much slower they should be avoided. The SAN's however have the advantage of good availability (backup restore). Check the papers on performance by M.Crevar like http://blogs.sas.com/content/sgf/2014/10/08/configuring-sas-what-to-know-before-you-install/ As you are Eminer I am little surprised by your focus on using SMC for libnames. Eminer does not benefit from that very well. The SMC is hiding the libname and possible other options on you system. Your time could be better invested on those parts of tuning your system and getting to know how to optimize resource usage and/or appropriate algorithmes.
