Product Description
This white paper announces the Compaq ProLiant ML330 Generation 2 Series of servers. The
Generation 2 (G2) models support two Intel Pentium®III 1.0GHz or 1.13GHz processors with
Flip-Chip Pin Grid Array (FC-PGA) technology and either 256KB or 512KB, respectively, of
Level 2 (L2) ECC cache memory.
The ATA models have an integrated dual channel Ultra ATA 100 controller with integrated ATA
RAID that can provide a maximum internal storage capacity of 160GB by using four 40GB one-
inch ATA/100 drives (two internal drive bays and two removable media bays). In addition, the
128MB standard ECC SDRAM DIMM memory for both ATA and SCSI models is now

Processor Technology
In addition to the changes bulleted above, the 1.13 Tualatin FC-PGA2 processors now include an
integrated heat spreader above the flip-chip core, making them easier to cool. They also now
have an attached heatsink, solving the problems faced when the processor and heatsink were
separated and then reattached.
An integrated VRM 8.5 powers the first processor; a socketed +12V input VRM 8.5 powers the
second. .13 –micron technology enables smaller, less expensive chips that run faster and require
less power.
Integrated ATA RAID Configuration Utility
The Integrated ATA RAID Configuration Utility is a standard feature of ProLiant ML330
Generation 2 ATA models. It supports, configures, and manages ATA hard drive arrays.
The AMI PCI-649 ATA100 controller provides two internal 100MB/s ports for up to four drives.
Integrated ATA RAID allows the user to install the operating system onto a fault-tolerant volume.
To run the utility, press the F8 key during POST, after all hard drives have been installed and
connected. Unlike a RAID volume created with an operating system, this server’s ROM-based
setup is used to create RAID 0, 1, and 0+1 arrays and assign drives. This information is then
written to a configuration sector on the drives. For further instruction on how to use this utility
refer to the Setup and Installation Guide. (See References at the end of this document.)
Note: The ROM-based RAID setup is not part of RBSU.

Compaq ProLiant ML330 G2 Service Overview 5
Rev. 1.0 Page 5 of 20
Compaq Integrated ATA RAID Management Utility
This is an application installed from SmartStart that provides array monitoring and reporting by:
■Monitoring the drives for failures
■Sending alerts to the operating system. (Compaq Insight Manager monitors the
system separately from the ATA RAID Management Utility.)
■Initiating automatic rebuilds (either to an online spare or to the new drive.)
With integrated ATA RAID, the operating system can be installed on a pre-configured mirror
(RAID 1 volume). Regardless of which drive fails, recovery of the mirror after replacing the
drive does not require user or operating system intervention.
ROM-Based Setup Utility (RBSU)
Like its predecessor, RBSU lets you view and establish server configuration settings during initial
system startup, as well as modify them after the server has been configured. Because the file
operates from the system ROM (unlike previous configuration utilities stored on a hard drive):
■The configuration parameters are always available, even if a drive fails.
■It only takes 3 to 5 seconds to run the utility (vs. 3 to 5 minutes).
■You can quickly install the latest version by flashing the system ROM with the latest
ROMPaq version.
In addition, RBSU checks each setting as it is made and immediately resolves possible conflicts
without bothering the administrator with an audible warning message. And, because it is
embedded in the ROM, you can use the Compaq Remote Insight Lights-Out Edition to remotely
access and configure the system.
Compaq Remote ROM Flash Utility
This utility allows administrators to upgrade the system ROMs as well as the supported Compaq
Smart Array controllers on multiple servers from a remote location. The ROM upgrades can
either be flashed individually or batched together to perform multiple ROM upgrades all at once.
Redundant ROM
If the server either loses power during a ROM flash or if the flash process is otherwise
interrupted, redundant ROM allows you to restart the system with the original ROM image.
Redundant ROM also allows you to use RBSU to switch between two ROM images for testing
and evaluation purposes. Through RBSU, you can restart the server using the previous ROM
image if a new ROM flash doesn’t meet your expectations — eliminating the need to use the
ROMPAQ Flash Utility to fall back to the previous ROM version.
Automatic Server Recovery-2 (ASR-2)
Like ASR, ASR-2 resets the system in the event of a catastrophic operating system error and it
restarts the server within a predetermined amount of time after the system stops responding. For
ASR-2, however, system administrators can set the interval in the RBSU.

Next Generation Remote Insight Support
The ML330 G2 has two connectors on the system board to support Remote Insight, Lights-Out
Edition boards. The 16-pin connector will support the existing board, while the 30-pin connector
will support the next generation board.
Enhanced Fan Control
A temperature-sensing device located near the processors now monitors the temperatures of both
processors and the ambient temperature of the chassis. When any of these three temperatures
reaches a predefined limit, the fan speed increases to control the temperature in the system.
Server Feature Bus
The Server Feature Bus is a proprietary bus that has PCI and management signals. Running the
management signals through this bus eliminates the need for the System Management Interface
Cable (SMIC) that was compulsory in the first generation ML330.
Server Feature Board
The server feature bus slot, located at the bottom of the system board, houses the Server Feature
Board. This board contains the ATA or SCSI, NIC, video, and management controllers.
There are two Server Feature Boards ―one for the SCSI models, the other for the ATA models.
Other than the drive controllers and associated connectors, the two boards are identical. The
SCSI models ship with only a SCSI drive controller; the ATA models ship with only an ATA
drive controller.
NMI Debug Button
The NMI Debug button is located on the Server Feature Board. NMI is a diagnostic mechanism
that allows for crash dump files to be created in situations when a system is hung and unable to
respond to traditional debug mechanisms. The NMI Debug button can be used to diagnose
software failures by forcing the operating system to invoke the Non-Maskable Interrupt (NMI)
handler and generate a crash dump log. This log can provide critical troubleshooting information
that may be difficult or impossible to obtain through other means.
The user initiates a Non Maskable Interrupt (NMI) by pressing the NMI Debug button. The NMI
can allow a hung system to become responsive enough to generate a crash dump log. The button
is enabled/disenabled in RBSU.
Warning! The NMI Debug button causes the unit to abruptly fail, as it is designed to do.
Therefore, it should never be used during normal operation.
ASR-2 is used when an automated crash dump is desired. Normally, ASR-2 provides a system
reset; however, ASR-2 can be configured to generate the NMI Crash Dump instead of a reset.

Internal Two-Bay Hot-Plug SCSI Drive
This is an option which is installed in the server's removable media bay area which will allow the
customer to add two additional hot-plug SCSI hard drives or a combination of one hot-plug SCSI
hard drive and one hot-plug SCSI tape drive.
LEDs
In addition to the system LEDs (on the front of the server) and network controller LEDs (on the
back of the server), the ML330 G2 now includes 15 diagnostic LEDs on the system board. These
LEDs indicate error conditions, such as processor, PPM, or memory module failures. Refer to the
graphic and table on the following pages to determine what these lights indicate.
For detailed information on the system and network controller LEDs, refer to Appendix E in the
Setup and Installation Guide. (See References at the end of this document.)

one DIMM at a time in the four memory sockets provided.
Integrated ATA RAID Troubleshooting Tips
Drive Connection
■If you have two drives, connect one per channel. The performance of the array is best
with one drive per channel, with both drives residing on the master connection of their
channel.
■Use the same type of drives or drives with similar speed and capacity.
■Do not use dissimilar drives on the same channel.
■Always use 80-conductor Ultra ATA cables.
■Use appropriate jumper settings3.
■Do not connect any ATAPI devices (e.g., CD-ROM, ZIP, or LS120 drive) to the ATA
controller.
3Refer to Appendix E, “LED Indicators, Switches, and Jumpers” in the Setup and Installation Guide. (See References.)

Configuration and Setup
Important:
■If you do not run the configuration utility setup (F8), the option ROM will automatically
configure the drives to RAID 0.
■You cannot add drives or remove drives from an array that has already been configured.
■All previous settings are lost when the Auto Configure option is run for RAID 0, RAID 1, and
RAID 0+1 arrays.
■RAID configurations do not support a stripe size less than 32KB.
■You cannot change the stripe size of an array that has already been configured.
■Enabling write cache (under WC-OFF) may cause data loss or corruption during an
unexpected power loss.
If you need to change array configuration, first back up your data. When an array configuration
changes, previous data in that array is lost. Use the table below to troubleshoot configuration and
setup problems:
