Overview
The Netra X4200 M2 server features two CPU sockets that support Next-Generation AMD Opteron,
model 2214 HE (L1 socket) embedded class processors. The server is supported with one or two
processors and each processor controls 2 pairs of DIMM slots, for a total of eight DIMM in a two CPU
system. There is a 6.4 GB/sec. access between processor and memory and one 1GHz 16x16
HyperTransport link between the two processors (8 GB/sec. Bandwidth).Through HyperTransport, each
processor can access the other processor's memory. In a system with a single CPU, the processor must be
placed into the designated processor slot0 that connects to the rest of the I/O infrastructure; this processor
only has access to 2 pairs of memory slots or maximum of 16GB using 4GB DIMMs.
The Netra X4200 M2 server supports 1 GB, 2GB and 4 GB registered DDR2-667 memory, for a system with up to
a total of 32 GB of memory. For optimal performance in both servers, memory DIMMs need to be
installed in pairs so the processor is able to run in 128-bit ECC mode. Systems with an odd number of
DIMMs are supported, but the processor will run in 64-bit ECC mode, reducing performance.
On-board management for the Netra X4200 M2 server is provided by a separately-powered Service
Processor (SP) based on a Motorola MPC8248 microcontroller that communicates with the two main
system processors and the rest of the system . Accessible to the end user through a serial port and a
dedicated 10/100 Ethernet NIC, ILOM provides the administrator with full lights-out manageability of
the these servers which includes the ability to power cycle, setup, manage, monitor and maintain the
system locally or remotely. ILOM supports both local and remote management, including remote KVM
and media connectivity. ILOM also provides industry standard GUI and CLI interfaces. IPMI 2.0 and
SNMP V1, v2c, V3 support also enable fast integration into a customers' existing monitoring schema.

Expansion Slots
The Netra X4200 M2 server is well equipped with both legacy PCI-X slots, and the more current PCI-E
high-speed slot.
• PCI-Express Slots
PCI-Express (PCI-E) is a high speed, point-to-point dual simplex chip interconnect. It is designed as
the next-generation system bus interconnect, replacing the aging PCI bus. PCI-E operates at 2.5GHz
and supports lane widths of x1, x4, and x8 in the Netra X4200 M2 server.
One x8 PCI-E slot is provided. The slot can also accommodate x1 or x4 cards. Most cards, including
InfiniBand cards, currently do not require more than a x4 slot for full bandwidth operation. Graphics
cards are the only currently available device that can come close to requiring the full x16 operation
that PCI-E can offer. These larger slots are usually provided specifically for graphics cards in high-
end 3D visualization-oriented workstations.
• PCI-X Slots
Three PCI-X slots are provided on the Netra X4200 M2 server to allow customers who need older
PCI or PCI-X I/O cards to continue using the older generation of cards. The PCI-X slots are all full-
height and two are full-length while one is half-length. They were designed to be able to support
legacy telco PCI cards that are still full height and full length.
The provided slots are both 133MHz, 64bit wide, 3.3V providing the highest speed available for the
older cards that are available in PCI-X configurations.
