The most valuable features include distinct storage within the Oracle PCA. This separate storage is crucial as it serves both primary and secondary purposes. Additionally, high-priority elements encompass Lava switches for network functionality. Recent efforts have focused on efficient patching of the entire PCA stack, covering the master node, computing nodes, network switches, and storage components.

• Flexibility to run mixed workloads for Oracle and non-Oracle environments.
• One stop to all your applications; for example, consolidation of various platforms, Linux, RHEL, WM Windows and Solaris into one single system.
• Provisioning for rapid application deployments (in just a few hours).
• Also, cloud-ready solutions.

• Scalability is a valuable feature, as compute nodes can be added as required. There is no force to increase form 1/8 Rack to 1/4 Rack as in Exalogic, for example. 
• All shipped SW is free, such as OVM and SDN. 
• Supports mixed compute node version, such as X4-2, X5-2 X6-2, etc., and capacity On Demand feature for both HW and Oracle licenses. 
• Fabric Interconnect Xsigo switches, which are used to connect PCA to the customer datacenter core switch or to the SAN switch, are very flexible and support all type of connectivity, such as QSFP, SAN port 16Gb, InfiniBand connectivity, etc.
• Supports connection to most of network topology, such as VLAN and network segmentation. 
• Oracle provides Linux and Solaris OS templates ready to create VM servers for PCA in OVA format.       

It's considered a converged system, so one of the real interesting things about it, you can have mixed workloads. You can install web server, app server, databases, rack, all those things, so it's pretty much an open-ended environment where you can install pretty much anything that you want to install on it as it's x86.
