34 Board Set Description

35MAXDATA PLATINUM 90002R Server System

 NOTE

The BIOS automatically detects, sizes, and initializes the memory array, depending on the type,

size, and speed of the installed DIMMs. The BIOS reports memory size and allocation to the system

through conguration registers.

The system does not support mixed-sized DIMMs or DIMMs from different vendors within the same

row.

DIMMs must be populated in groups of four, referred to as a row. Row 1 consists of DIMM sockets

1-4 and row 2 consists of DIMM sockets 5-8. The DIMM sockets in each row are not side-by-side;

see Figure 18 to identify each socket and row.

Within a single row, all DIMMs must be identical, both in DIMM size and the number of devices on the

DIMM. Each of the two DIMM rows can be populated with DIMMs that use different technologies,

but for the best performance, the amount of memory on each MRH-D DDR branch channel should

be the same to enable the benets of memory interleaving.

SCSI Controller

The LSI-531030 SCSI controller (U320) on the main board provides one primary channel to internal

SCSI backplane and a secondary channel via an external SCSI connector at the rear of the chassis.

This device interfaces to the SIOH at clock frequencies up to 133 MHz through one channel of the

primary P64H2, also located on the main board. The 53C1030 is a fully autonomous device, capable

of managing multiple I/O operations and associated data transfers from start to nish without host

intervention.

While the internal channel supports only Low Voltage Differential (LVD) signaling, the external channel

supports both LVD and SE (single-ended) signaling. With LVD signaling, the channels can each support

a maximum data rate of 320 MB/sec.

Network Interface Controller

The onboard network interface is comprised of one Intel

82546EB Dual Port Gigabit Ethernet controller

connected to the second channel of the primary P64H2 PCI-X bridge, located on the main board,

at clock frequencies up to 133 MHz. The 82546EB is a single component with two fully IEEE 802.3

compliant Ethernet interfaces. It provides two stacked RJ45 ports at the rear of the chassis.

This network interface supports Ethernet applications at 1000Base-T, 100Base-T, and 10Base-T (802.3,

802.3u and 802.3ab) and enables network manageability implementations required for remote control

and alert over LAN.

Video Controller

The onboard, integrated ATI RAGE XL 64-bit SVGA chip contains an SVGA controller that is fully

compatible with industry video standards. The video sub-system implements 8 MB of 10-nanosecond

onboard video memory.

The video controller supports pixel resolutions of up to 1600 x 1200 and up to 16.7 million colors

and provides hardware-accelerated bit block transfers of data. The SVGA controller supports analog

VGA monitors (single and multiple frequency, interlaced and noninterlaced) with a maximum vertical

retrace noninterlaced frequency of 100 Hz.

Video connectors are located at both the front and the rear of the chassis. The connectors are auto

sensed and only one can be used at a time. The connector at the front of the chassis supports

resolutions up to 800 x 600.
