Hardware Architecture
The Sun Netra CP3060 blade server is an ATCA node blade server based on the
UltraSPARC T1 processor. It is hot-swappable to an ATCA midplane and supports
two 1000BASE-T Ethernet interfaces as Base interface and two 1000 SERDES
Ethernet interfaces as Extended interface to support redundant Dual Star topology.
The Sun Netra CP3060 blade server supports eight standard DDR-2 Very low profile
(VLP) DIMMs, which can support the maximum memory of 16 Gbytes.
The I/O subsystem is designed around the JBus-to-PCI-E ASIC which is the bridge
between the processor bus (JBus) and the PCI-E links. The JBus-to-PCI-E bridge has
one PCI-E x4 link (Leaf A) and one PCI-E x8 link (Leaf B). Leaf A is wired to a
gigabit Ethernet controller which provides the SERDES Extended interface. Leaf B is
wired to the PCI-E switch ASIC (PLX8532) and provides the Base interface.
The PCI-E switch ASIC on Leaf B connects to the Southbridge, the AMC slot, the
Zone 3 RTM connector, and a gigabit Ethernet controller for the Base interface and
maintenance ports.
The Southbridge has a built-in IDE controller that provides support for Compact
Flash, and a SATA controller with four 3-Gbps SATA ports, of which two are
connected to the AMC connector and the two are connected to the Zone 3 RTM
connector.
