KEY PRODUCT FEATURES & USER BENEFITS

Next-generation Xeon Processing and Enhanced System Architecture

NEC Express5800/120Rf-2 is built to take full advantage of the latest Xeon processors from 2.80BGHz up to 3.20GHz. These processors are packaged in the new FC-mPGA2 form factor, a 603-pin socket version of the Xeon.

The design of NEC Express5800/120Rf-2 is built upon a 533MHz Front Side Bus (FSB), the E7501 chipset from Intel and DDR266 SDRAM memory. The Intel Xeon processor for dual- processing servers offers users several new system performance boosts, with the Intel Netburst microarchitecture on Intel’s 0.13-micron manufacturing process, Hyper-Threading technology, a larger cache size and the E7501 server chipset.

The Intel E7501 chipset supports DDR memory technology and is optimized for the Intel Xeon processor. The new chipset will accelerate memory access to increase platform performance and deliver new levels of performance for I/O intensive server applications.

This chipset also allows increased throughput and enhanced overall system performance through	Xeon TM processor
the high-performance 533MHz FSB and full-speed 266MHz memory access.
The I/O subsystem of NEC Express5800/120Rf-2 is built on a dual peer PCI bus architecture
that provides concurrency of data transfers between the different high speed I/O channels and
CPU or memory. I/O traffic is balanced as follows:
- First PCI bus (32-bit): IDE, graphics and I/O ports
- Second PCI bus (64-bit): Dual-port LAN and 3x 64-bit full-height PCI slots
- Third PCI bus (64-bit): Ultra 320 SCSI channels and 3x 64-bit low-profile PCI slots

Improved Memory Architecture

NEC Express5800/120Rf-2 offers 6 DIMM sockets for industry-standard 128MB, 256MB, 512MB, 1GB or 2GB SDRAM DDR266 DIMM. The Express5800/120Rf-2 allows easy expansion of system’s capabilities to memory-intensive environments (scalability up to 12GB) and comes standard with 9-bit parity/ECC 266MHz SDRAM for maximum data integrity.

High-performance Ultra 320 Disk Drives and Flexible Storage Configurations

NEC Express5800/120Rf-2 supports the latest disk drives with Ultra 320 SCSI technology (10Krpm or 15Krpm), giving data rates of up to 320MB/s for maximum throughput.

The Express5800/120Rf-2 includes a 3.5- inch diskette drive, a CD-ROM drive, six hot-swap SCSI hard disk drive bays, and removable media device bay.

The hot-swap SCSI hard disk drive bays support up to seven 1-inch SCSI hard disk drives that can be swapped in or out of the system without powering it down, if RAID functionality is configured in the system.
