Techopedia explains Exadata
Exadata is a database appliance that has the capability to provide support to a combination of database systems such as OLTP and OLAP, the transactional and analytical database systems. Exadata was initially designed in a collaborative effort between Oracle and HP, in which Oracle powered the Linux-based OS and database software, while HP designed the system's server hardware. However, after Oracle acquired Sun Microsystems in 2010, Exadata Version 2 came to use Sun Microsystems Storage Systems technology.
