Integrated Ultra 320 I/O Controller
NEC Express5800/120Rf-2 system board features an integrated dual-channel SCSI controller providing Ultra 320 SCSI interfaces for the support of Ultra 320 hard disk drives and SCSI media devices (DAT, AIT).
The system board also includes a single channel EIDE controller providing support for the internally mounted CD-ROM.
Multiple RAID Options
NEC Express5800/120Rf-2 comes with a complete range of optional high-performance Ultra 320 RAID boards. These boards give top levels of performance, maximum reliability and fault tolerance when running demanding server applications.
•The 64bit RAID controller features 2x Ultra 320 SCSI channels, Intel GC80303 processor and 128MB of cache with battery backup unit.
•The 64bit RAID controller features 1x Ultra 320 SCSI channel, Intel GC80302 processor and 64MB of cache without battery backup unit. It is possible to add optional battery backup unit.
Embedded Auto-sensing 10/100/1000Mbps Ethernet
NEC Express5800/120Rf-2’s system board includes a dual-channel gigabit network interface controller based on the Intel 82546EB. The 82546EB is a highly integrated PCI LAN controller in a 21 mm2 PBGA package. The controller supports 10/100/1000 operation on both the channels and it supports alert-on-LAN functionality.
The 82546EB controller supports the following features:
-64-bit, 100MHz PCI-X interface
-Integrated IEEE 802.3 10Base-T, 100BASE-TX, and 1000Base-T compatible PHY
-IEEE 820.3u auto-negotiation support
-Chained memory structure similar to the 82559, 82558, 82557 and 82596
-Full duplex support at both 10 Mbps, 100Mbps and 1000Mbps operation
-Low power +3.3 V device
The auto-sensing PRO/100+ Server Adapter from Intel can also be supported on NEC Express5800/120Rf-2. By installing multiple PRO/100+ boards, high-availability (load balancing, fault tolerance) and top performance features are provided for the most demanding networking environments.
