The vendor's specifications and advertising content usually indicate the total parameters (360 processor kernels and 2.9 TB RAM for full rack). An X3-2 model was announced in 2012 with newer processors and more memory. Since late 2013 an X4-2 model is commercially available, it has yet more processor cores and four times as large capacity of solid-state drives.
The latest version of Exalogic compute nodes have two Intel E5-2699v3 2.3 GHz Xeon (18-core) processors and eight 32 GB DDR4 2133 MHz RAM for a total of 256 GB per node. Two 400 GB SSDs (RAID1) and redundant power supplies

, presumes that any appliance principally lacks scalability for the end-user compared with the infrastructure, supplied as service, and notes that the Exalogic approach is actually a rollback to the obsolete mainframe computer concept. Also, commentators have expressed concerns about the appropriateness of placing the word "elastic" in the name, because, despite the ability to load balance, there are obvious computing limits of the box, and those limits cannot be transcended like they should be in a true elastic environment; the same criticism applies to all solutions designed for private cloud computing, in particular, it applies to
