Sun Fire X4500
In July 2008, Sun announced the X4540 model (code-named Thor), which doubles the processing power of the X4500.
In November 2010, Oracle designated that the X4540 is end-of-life and has no next-generation replacement model. 
Thumper was developed by Palo Alto, California based company Kealia inc. Kealia was founded in 2001 by Stanford University professor David Cheriton and Sun co-founder Andy Bechtolsheim. When Sun bought Kealia in 2004, Thumper became the basis for the X4500 model.
The Sun Fire X4540 supports two quad- or six-core AMD K10 (Barcelona) processors and up to 128 GB RAM. The new model also uses PCI Express IO technology, and added a compact flash disk slot for booting the operating system.
A significant feature of both systems is that the I/O framework was designed to handle high throughput on all disks simultaneously. These were the first systems designed specifically with ZFS in mind, so no hardware RAID is included.
