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
2
in a 21 mm
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:
-

-
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.
