System features
The Altos G900 is a powerful server system loaded with a host of new
and innovative features. The system offers a new standard for flexible
productivity ideal for general business applications, email, web service,
file clustering and print services.

Processors

The Altos G900 server accommodates one to four processors from the
Intel® Xeon™ processor family.

Memory

The memory board contains twelve 184-pin DIMM slots each
supporting 72-bit ECC (64-bit main memory plus ECC) registered PC-266
Double Data Rate (DDR) DIMMs. Memory is partitioned in three banks.
You may install a minimum of 512 MB (128 MB x 4) or as much as
24 GB.
• Minimum configuration: Four 128-MB DIMMs, for a total of
512 MB
• Maximum configuration: Twelve 2-GB stacked DIMMs for a total
of 24 GB
The controller automatically detects, sizes, and initializes the memory
array, depending on the type, size, and speed of the installed DIMMs,
and reports memory size and allocation to the server via configuration
registers.

SCSI controller

The mainboard includes an embedded Adaptec® 7902 SCSI controller,
which contains two independent SCSI channels. You can disable the
SCSI controller in BIOS setup. Both channels support 16-bit SE or LVD
SCSI operations at the following speeds:
• Ultra320 (320/MB/sec)
• Ultra160 (160 MB/sec)
• Ultra2 (80 MB/sec)
• Ultra Wide SE (40 MB/sec)
