KEY PRODUCT FEATURES & USER BENEFITS

Next-generation Xeon Processing and Enhanced System Architecture

NEC Express5800/120Lh is built to take full advantage of the latest Xeon processors. The new Xeon processor incorporates Extended Memory 64 Technology (EM64T). By supporting EM64T, memory addressing has been extended to run 64-bit code, allowing traditional processors to access larger memory amounts of higher than 4GB.

The design of NEC Express5800/120Lh is built upon a 800MHz Front Side Bus (FSB), the E7520 chipset from Intel and PC2700 SDRAM memory. The E7520 chipset offers higher processor speeds for dual-processor allows increased throughput and enhanced overall system performance through the high-performance 800MHz FSB.

The I/O subsystem of NEC Express5800/120Lh provides concurrency of data transfers between the different high speed I/O channels and CPU or memory.

Improved Memory Architecture

NEC Express5800/120Lh offers 8 DIMM sockets for industry-standard 256MB, 512MB, 1GB and 2GB SDRAM PC2700 DIMM. The Express5800/120Lh allows easy expansion of system’s capabilities to memory-intensive environments (scalability up to 16GB) and comes standard with DDR 333MHz SDRAM for maximum data integrity.

NEC Express5800/120Lh supports chipkill memory, memory mirroring and on-line spare memory to ensure continuous system operation.

High-performance Ultra 320 Disk Drives

NEC Express5800/120Lh supports the advanced disk drives with Ultra320 SCSI technology (10Krpm or 15Krpm), giving data rates of up to 320MBps for excellent throughput. The system is equipped with 6 hot-swap disk bays. In addition, three more hard disk drives can be added by installing the HDD Adapter Kit for Device Bay in the 5-inch device bays. (two device bays are occupied)

Integrated Ultra 320 I/O Controller with Integrated RAID0/1

NEC Express5800/120Lh system board features an integrated two-channel SCSI controller, providing Ultra320 SCSI interfaces to support Ultra320 hard-disk drives and SCSI media devices such as DAT and AIT.

This SCSI controller supports RAID 0/1 as standard. This prevents loss of important data and allows higher system availability in the event of a disk failure, while reducing the cost for the extra device.

The system board also includes a single-channel EIDE controller, providing support for the internally mounted CD-ROM drive.
