Although the LSI SAS1064 controller is capable of supporting both SAS and SATA drive types, the Sun Fire
X4600 server will only support the SAS hard disk drives, which provide higher performance and better reliabil-
ity. Currently, high-density, 10,000-RPM, 73-GB hard disks are supported.

Intel 82546GB Dual Port Gigabit Ethernet Controllers
Sun Fire X4600 server is equipped with two Intel 82546GB Dual Port Gigabit Ethernet controllers that provide
quad Gigabit Ethernet interfaces to the server platform. These servers are the first x64 rack-optimized servers
available with four on-board Gigabit Ethernet ports for reducing network complexity. The Intel 82546GB Dual
Port Gigabit Ethernet controller provides two 64-bit fully integrated Gigabit Ethernet Media Access Control
(MAC) and physical layer (PHY) functions. It is capable of transmitting and receiving data at
10/100/1000MB/sec. data rate with half or full duplex capability. Additional features of the Intel 82546GB Dual
