In my organization there has always been a need for high-performance computing, and we decided to go with Oracle SuperCluster for this reason coupled with the fact that we already use Oracle products such as Solaris (11.4), which is itself a component of SuperCluster.
As far as performance is concerned, SuperCluster is a system of machines engineered for high performance and reliability, while supporting a number of modern enterprise storage and database technologies such as Exadata and ZFS. The memory, along with Oracle's M7 servers, is also very good in terms of performance.
We use SuperCluster on-premises, with about 3,000 people who access it on a daily basis. Essentially, whoever is accessing the applications we use, is also accessing the SuperCluster. That includes our database administrators, system administrators, and many other administrators of various kinds.
