In my current role I have the privilege of managing the Performance Lab in SAS R&D. Helping users work through performance challenges is a critical part of the Lab’s mission. This spring, my team has been actively testing new and enhanced storage arrays from EMC along with the Veritas clustered
I look forward to SAS Global Forum each year and this past conference ranked up that as one of the best I've ever attended. This year there were so many wonderful presentations, Super Demos and workshops on the topic of administration of SAS and the underlying hardware infrastructure needed for SAS
With memory being affordable now, we are constantly being asked by customers about doubling and tripling the amount of RAM that SAS recommends. More is better, right? Often, but we have found a specific scenario using SAS datasets where that is not the case. Remember, that increasing memory generally means a commensurate

My Performance Validation team in SAS R&D is constantly working with our partners to test how their storage arrays work with SAS. In late 2014, we finalized several papers that discuss how a mixed analytics workload performs on several storage arrays. While doing this testing, we also listed lessons-learned in
With the growing use of SAS on commodity hardware, many organizations are running lots of SAS servers on separate instances of operating system in a SAS infrastructure. This configuration is great for optimizing resources, but when these SAS servers have to share data, then SAS recommends the use of a clustered
