The ASUS Z8PE-D12 motherboard is based upon Intel’s 5520 IOH (Input Output Hub). The 5520 IOH supports dual Intel Xeon CPUs with up to 6 cores and is the functional equivalent of the X58 chipset on the single CPU space. The 5520 supports all Intel Xeon LGA-1366 5 Series CPUs including the latest 5690 and below CPUs. Each Xeon CPU has a separate memory controller built into the CPU. The board itself has 12 DIMM slots that can handle up to 8GB DDR3 DIMMs or 96GB total. Each CPU has a Triple Channel memory controller, meaning that it must be installed in groups of three for each CPU to get the full benefit of triple channel memory on it. Flex-E stands for Flexible-Express. The board has the option of using a single PCI Express x16 slot or splitting the lanes into two x8 links for I/O expansion allowing the customers to use PCI-E link with more flexibility. There is also a MIO audio card that can be added to the board to offer great sound to complement the onboard integrated graphics. One of the issues with server motherboards is storage. The ASUS Z8PE-D12 motherboard supports ASUS’s PIKE (Proprietary I/O Expansion Kit Expansion) system. This is a SAS controller that plugs into a PIKE slot on the board offering up to 8 SAS ports in addition to the six SATA 2 ports on the D8PE-D12 board. Supported PIKE cards include the 1064E, the 1068E, the 1078 and the 6480 PIKE cards. The ASUS ASMB3-IKVM Upgrade Kit is an interesting concept in that it allows the administrator to remote manages the servers from anywhere and anytime. Through the integration of ASMB3 IKVM MIS is capable of remote real-time access to servers with full control by keyboard, video monitor and mouse (KVM) of a single local computer from anywhere at any time. KVM over LAN allows administrators to share the data saved to a local drive (floppy, CD/DVD-ROM, flash device HDD) to target servers.
The ASUS Energy Processing Unit is a chip that controls the Power Phases of the CPU, the motherboard, and the memory. The use of this chip on a Server motherboard allows for lower power consumption of the board especially when the system doesn’t need all of the performance available to it. Running a program like AutoCAD is much more intensive than surfing the Net on most things. The onboard graphics is in the form of an Aspeed AST2050 Mainstream PCI Graphics and Remote Management Processor. The server computer does not need a gaming video card like the HD 5870 or the workstation equivalent to run as the computer would not do gaming or other such tasks in most situations. The AST2050 uses an ARM926EJ 200MHz processor with 16KB/16KB Cache. This processor has 8MB of 200MHz DDR-II RAM allowing a maximum of 1600x1200 resolutions. Contents:
