Any chance this could be a Via-NSM chipset? Recent agreements between these two seem ominous for Intel.

wouldn't be using Intel chipsets. That's why I want to find out what chipset they're using.

Tenchusatsu,

Most motherboards based on Intel chipsets feature five PCI slots, not six. Remember that the article said Compaq's server will have five Ethernet cards, not jacks. With all five slots gone, where does that SCSI card go?

Supermicro make several motherboards with 5 PCI slots, AGP slot and on-board Ultra 2 SCSI.

The P6DBU uses the 440BX chipset and supports 1Gbyte registered DRAM, while the P6DGU uses the 440GX chipset and supports 2 Gbyte ram.

These are both dual processor motherboards, but I believe they will work with a single Celeron.

Ten, <With all five slots gone, where does that SCSI card go?>
<There are only two Intel chipsets currently being
manufactured that support more than 512MB>

Kid, slow down. Example:

asus.com.tw
(440BX, 6 PCI, 1GB DRAM)

<why would anyone want to put six bandwidth-hungry
PCI cards onto one PCI bus?>
Each 100mbit Ethernet is only 10MB/s, times 6 = 60MBytes/s,
which is about half of PCI-33 bandwidth. Actually the whole
thing will be limited by SCSI subsystem.

You should know better the infrastructure your company
sells into.

Ten,

OK, 810 supports at most five PCI slots and 512MB. So they use a BX which will do 1GB.

The article writers ability to differentiate ports/cards/slots may be in question.

Here's a standard motherboard that supports 8 IDE hard drives using a BX chipset.

Ten,

Regarding bandwidth, a 10Mb NIC will rarely reach 50% of rated throughput in any box, same for the 100Mb. So your bandwidth calculations can be halved to start with, same for the SCSI devices, or IDE for that matter, even when RAID'd together the throughput is no where near the theoretical limits. Oh, by the way, RAID, now that would be a good way to get six or more disks in a box off a single controller IDE/SCSI.
