are essential to the Sun Netra CP3060 blade server’s system architecture. Relative to
the PCI-E interconnect, the Sun Netra CP3060 blade server uses a 4x link to access
the M1575.
The major functional blocks used are listed below and described in the paragraphs
which follow:
■
UltraDMA IDE controller – The primary port is used to provide the connection to
the Compact Flash and it supports speeds of 66/100/133.
■
SATA controller with four 3-Gbps SATA ports.
Configuring the internal devices of the Southbridge is very simple. There is a central
switching/routing block inside the Southbridge chip that maps the PCI-E incoming
data to the intended downstream device. Thus the Southbridge can be viewed as a
collection of PCI devices within a single package. The functional units within
Southbridge, which appear to firmware as unique PCI devices, are listed in
TABLE 5-2
. The Southbridge’s standard PCI device configuration is used to control the
device behavior on the PCI bus and to allocate PCI Memory and I/O space address
ranges needed by the device.
PCI IDE Controller
The IDE controller is resident inside the Southbridge. This is a dual controller but
only the primary bus is utilized to connect the Compact Flash drive on the Sun
Netra CP3060 blade server. The bus can operate at DMA mode 4 speed.
Compact Flash
The Sun Netra CP3060 blade server provides the option of supporting an IDE
Compact Flash card. In order to support higher memory capacity, a Type II CF
socket is provided.
The Compact Flash card is not hot-swappable and there is no access to the CF socket
once the blade server is installed in an ATCA chassis.
SATA controller
A dual 3-Gbps SATA port is connected to the AMC connector
