1System overview
Introduction
The Dell™ PowerEdge™ T620 is a feature-rich, two-socket tower server with up to 24 DIMM slots,
storage capacity of up to 32 2.5-inch or 12 3.5-inch drive bays, and processing power from the
Intel®Xeon®processor E5-2600 or E5-2600 v2 product families. The T620 shines in its ability to
handle demanding workloads with up to 16 processor cores, high memory density, and high I/O
bandwidth. The T620 is an excellent platform for key applications such as business analytics and
intelligence, information management, customer relationship management, security management,
desktop virtualization, medical imaging, and graphical rendering.
Designed for demanding small- and medium-sized business environments and
enterprise data centers
The extensive 768GB memory footprint, large local storage capacity, and I/O flexibility of the
PowerEdge T620 make it an attractive platform for a wide range of applications and workloads,
including server consolidation and virtualization. The T620 features allow you to achieve space
savings, use your IT administrator’s time more efficiently, and minimize potential software licensing
fees.
The T620 is a flexible server with excellent energy efficiency and acoustical performance, allowing it
to be placed into quiet office settings. The T620 can also be rack-mounted and is fully compatible
with rack infrastructures. Businesses and organizations with remote offices need not worry, as the
T620 offers consistent worldwide support.
Safeguard your data and business
Features that protect data and help keep your server running are essential. The T620 and its large
storage capacity offer both software-based RAID and hardware RAID controller options to protect
critical business information. Features that help to keep your business up and running include
reliability, availability, and serviceability (RAS) options like hot-pluggable fans, disks, and power
supplies, along with redundant, failsafe hypervisors that minimize the need to take a server away
from productive work to replace parts.
Simplified systems management, without compromise
The Dell OpenManage™ systems management portfolio includes Integrated Dell Remote Access
Controller 7 (iDRAC7) with Lifecycle Controller. This embedded feature helps IT administrators
manage Dell servers in physical, virtual, local and remote environments, operating in-band or out-
of-band, with or without a systems management software agent installed.
OpenManage iDRAC with Lifecycle Controller integrates and connects to leading third-party
systems management solutions (such as those from Microsoft, VMware and BMC Software), so users
can maintain a single point of control and capitalize on an existing systems management investment.
OpenManage simplifies the lifecycle of deploying, updating, monitoring and maintaining Dell
PowerEdge servers.

Processor features
The Intel Xeon processor E5-2600 v2 product family has powerful new features and improves upon
many of the capabilities of the predecessor Intel Xeon processor E5-2600 series:
With up to four additional cores, 10MB more cache and a 17% increase in memory speeds,
E5-2600 v2 processors may boost performance by up to 40% in Dell PowerEdge server
platforms
Support for DDR3 1866MT/s memory provides faster connections throughout the system
Up to 24 DIMM slots and support for up to 32GB DIMMs enable memory capacity of 768GB
Dell’s exclusive Fault Resilient Memory technology provides a protected memory zone for a
hypervisor without consuming half of the total RAM in the system,
In combination with Fault Resilient Memory, E5-2600 v2 processors offer Failsafe Virtualization
for unsurpassed industry protection for virtual machines.
Intel Secure Key and Intel OS Guard deliver faster and more secure encryption
Advanced Programmable Interrupt Controller virtualization (APICv) improves virtualization
performance by reducing virtual machine (VM) exits, thereby reducing overhead required to
service every APIC interrupt
Intel Integrated PCI Express 3.0 provides up to 40 lanes per socket
Intel Turbo Boost Technology 2.0 delivers up to double the boost than the previous-generation
turbo technology
Dell Processor Acceleration Technology (DPAT), enabled through the BIOS, minimizes transition
duration when the processor functions in turbo mode, thereby decreasing jitter and allowing for
lesser latency.
Intel Data Direct I/O (DDIO) allows I/O traffic to skip the main system memory and be directed
straight to the processor cache, which can provide a significant reduction in latency as well as
allowing memory to remain in a low-power state
Intel Advanced Vector Extensions offer up to double the floating point operations per clock
cycle by doubling the length of registers, which can be useful in large-number calculations,
integral to many technical, financial and scientific computing problems.

GPU configuration options
GPU cards are installed in the PCIe x16 2.0 interfaces, which are slots 2, 4, 5 and 7; slots 5 and 7 only
work with two processors.
Note: You must select the GPU enablement kit at point of sale to install GPU or keep the system's
GPGPU capability. GPU enablement kit is not upgradable after point of sales.
With one processor installed, two GPU cards are supported with the following restrictions:
Slots 1, 2, 3 and 4 are available, therefore only two GPUs can be installed in slots 2 and 4
Since double-wide GPU cards occupy two slots, only two can be installed and slots 1 and 3 are
not available
RAID cards cannot be installed with two double-wide GPU cards
