Dell PowerEdge T420
The Dell™ PowerEdge™ T420, a 2-socket tower server, delivers performance,
expandability and reliability in a quiet office setting.
The Dell PowerEdge T420 is a powerful and
reliable 2-socket tower server that delivers
performance and built-in capacity for
non-disruptive growth. The T420’s acoustical
profile allows it to fit unobtrusively into quiet
office environments and data centers alike.
This tower server is an excellent fit for generalpurpose small and medium business workloads
such as database, file and print sharing, retail
and email. The T420 also fulfills platform needs
in small offices with the growing trend of virtual
desktop infrastructure (VDI). Hot pluggability
of key components, combined with leading
manageability, make it an excellent server for
branch offices and other remote sites where IT
skills might not be present. Consistent worldwide
support makes it highly appealing to multinational
businesses and organizations with remote offices.
A versatile workhorse
Featuring the extensive performance of two
Intel® Xeon® E5-2400 processors, and
complemented by substantial memory capacity
and broad I/O bandwidth, the T420 provides
high, balanced performance and built-in room
for growth. Its twelve DIMM slots and six PCIe
slots provide memory density and wide I/O
bandwidth to support both memory-intensive
and data-intensive applications and databases.
Built-in capacity for up to eight 3.5-inch or
sixteen 2.5-inch hard drives accommodate
data storage as your business or organization
grows. These combined technology features are
necessary to support consolidated and virtualized
environments, a role in which the T420 also
To protect your virtualized workloads, the
PowerEdge T420 offers dual SD media making
your hypervisors redundant and failsafe. Other
reliability and availability features include
