The Gateway ALR 9200 Server is the newest addition to the ALR Server series that offers the combined technologies of Gateway 2000 and Advanced Logic Research (ALR), which is now a Gateway business unit. The ALR 9200 is Gateway's enterprise quad Xeon server system for transaction-intensive applications. At only 18" high, 12.25" wide, and 25.5" deep, the ALR 9200 fits both office and computing environments.

Inside the System
The ALR 9200's cabinet design isn't tool-less but only requires loosening three screws on the system's back to remove the side panel and gain access to card slots and memory. Molded foam inserts hold the cooling fans in place and direct the airflow within the system. The system I tested had five cooling fans (with room for three more), which provided ample cooling for the system components. The Seagate Cheetah 10,000rpm hard disks in hot-swappable disk bays are equipped with heat sinks to promote the necessary cooling for extended hard disk life.

Removing two additional screws lets both the front hard disk cage and the rear electronics cage pivot out and provide access to cable connectors on the motherboard. In this ALR 9200 system, a RAID controller connected five disks, which left one hot-swappable hard disk bay unused. First, I chose to configure all the disks for fault tolerance. For the boot volume, I configured two of the disks for RAID 1 (mirroring). Then, I configured the other three hard disks for RAID 5, which created an 8.5GB data volume. Because the ADAC Ultra 2 model S466 RAID controller doesn't incorporate battery-backed cache, I configured it for data security with the write-through and direct I/O options. (The Gateway's model S438 three-channel controller, which is based on AMI technology and customized to Gateway's specifications, has battery backup for the cache, so I would feel more comfortable configuring this controller for performance with the write-back option.) For more information about controller configuration, see the sidebar "RAID Performance Configuration," page 160. To accommodate attachment to the Lab's four benchmark network segments, I replaced the 3Com 10/100 Ethernet card with a four-port Cogent 10/100 Ethernet card. Access to memory slots in the ALR 9200 is painless because the memory card, which has 16 DIMM sockets, slides easily out of the cabinet.

I installed Windows NT Server 4.0 with Service Pack 3 (SP3) without incident to a 2GB hard disk volume on the mirror set. The installation required minimal reference to the system manuals. In addition to the User's Guide, which covers the system's basic operation, Gateway also includes Maintaining and Troubleshooting the Gateway ALR 9200 Server, which thoroughly covers BIOS and hardware configuration and how to use the system utilities.

Systems Management
The ALR 9200 has two features that support remote systems management: the Intel Server Control (ISC) software and the Emergency Management Port (EMP) Console. You'll find both the ISC and the EMP Console on the System Utility CD-ROM.

ISC. ISC uses the server's implementation of Desktop Management Interface (DMI) 2.0 to provide current operational status information for server hardware components. In addition, you can use ISC in conjunction with the supported enterprise management platforms (i.e., HP OpenView Network Node Manager, Intel LANDesk Server Manager, and Computer Associates Unicenter TNG) to generate alerts. Because Intel wrote ISC as an ActiveX control, in standalone mode you can access ISC through a Web browser that supports ActiveX or a container application, such as the Microsoft Management Console (MMC).

I chose to use the MMC to test ISC. ISC's ActiveX control first presents a list of managed servers by OS. For each server on the list, ISC displays icons for two components: the ISC console and the Intel DMI Explorer. The DMI Explorer lets you view or set attributes for each DMI-compliant component on the system. The DMI Explorer presents the attributes as mostly undefined numeric codes, which provide little value without a fundamental understanding of the data.

The ISC console provides the functionality. Screen 1 displays a hierarchical tree structure of servers and monitored components in the ISC's left pane and a the selected folder's configuration information in the right pane. When you expand the server folder to show the monitored component categories, an indicator of the server's overall health displays at the top. (I would rather have the health icon display beside the collapsed server folders to provide a compact visual representation of the health of several servers.) The icon is green to identify a healthy state and turns red (i.e., critical) or yellow (i.e., noncritical) for unhealthy states. You can select the health item to display a summary of all sensors reporting error conditions, which lets you quickly drill down into the subsystem that is reporting a problem.
