Delivering Optimum Price/Performance
NEC understands the desire of companies
to bring business-critical reliability to their
computer systems without paying high prices.
The Express5800 MH4000 was built to address
today's applications at the departmental and
enterprise level while providing unprecedented
investment protection.
The MH4000 supports up to 4 Pentium Pro
processors operating at 200MHz,each with
512KB of L2 cache.It implements dual integrated
PCI Ultra SCSI controllers for maximum
system performance and throughput. With up
to 4GB of error correcting memory (ECC),
and dual PCI peer busses (132MB each),the
MH4000 delivers outstanding performance and
expansion capability to cover future requirements.
Balanced Scaleable Architecture
The modular architecture of the MH4000 is
designed to support a wide range of power,
security and storage expansion requirements
while preserving existing investments.NEC
offers server capabilities matched to today's
needs while still offering significant expansion
to cover future requirements.
• Supports two CPU boards,each with 2 ZIF
sockets for the 200MHz Pentium Pro CPUs
for easy system upgrades
• Supports up to 4GB of ECC memory with 16
DIMM sockets for increased memory flexibility
• Provides 10 I/O slots (6 PCI,4 EISA)
backed by dual peer PCI buses to provide
optimal expansion capability for new and
existing cards
• Includes six 1.6" hot plug disk bays and up
to three hot swap power supplies for
increased system availability
High-Availability Features Minimize
Down-Time
Server reliability in business critical applications is
crucial to running your business.The MH4000
runs critical applications with redundant hardware
components that minimize server downtime.
• Hot plug disks,redundant hot swap power
supplies and cooling fans for increased
system availability and reduced server
downtime
• Available RAID for optimal system
performance
• Up to 4GB error correcting memory
(ECC) for guaranteed data protection
• 16 DIMM sites for flexible memory
expansion at a lower cost
• Robust chassis design for increased system
reliability and capability
• Support for NEC network management
suite with SNMP agents that support HP
OpenView for Windows and other SNMP
compatible management systems
As small and medium businesses or
departments and workgroups of larger
enterprises create greater demand on
computing resources, companies are
looking for an Intel-based server that
delivers the scaleability and reliability
expected of a high-end server at an
affordable price.
That's why NEC delivers the powerful
Express5800
™
MH4000 server ready to
run a wide range of business critical
applications. The MH4000 supports up to
four Pentium
®
Pro processors and is built
with high availability, expandability and
unmatched price performance. Designed
for demanding multi-user environments,
it’s ideal for business critical, transaction
processing, database and Internet/
Intranet applications.
