Redundant Array of Independent Disks (RAID)
For optimal performance when configuring drives as a RAID volume, Dell Technologies recommends drive models that are
identical.
Specifications of OptiPlex Small Form Factor Plus 7020
21
Customer’s Internal Use Only – Confidential &amp; Subject to NDA
NOTE: RAID is not supported on Intel Optane configurations.
RAID 0 (Striped, Performance) volumes benefit from higher performance when drives are matched because the data is split
across multiple drives: any I/O operations with block sizes larger than the stripe size splits the I/O and become constrained by
the slowest of the drives. For RAID 0 I/O operations where block sizes are smaller than the stripe size, whichever drive the I/O
operation targets, determines the performance, which increases variability and results in inconsistent latencies. This variability
is particularly pronounced for write operations, and it can be problematic for applications that are latency sensitive. One such
example of this is any application that performs thousands of random writes per second in very small block sizes.
RAID 1 (Mirrored, Data Protection) volumes benefit from higher performance when drives are matched because the data
is mirrored across multiple drives all I/O operations must be performed identically to both drives, thus variations in drive
performance when the models are different result in the I/O operations completing only as fast as the slowest drive. While this
does not suffer from the variable latency issue in small random I/O operations as with RAID 0 across heterogeneous drives, the
impact is nonetheless large because the higher performing drive becomes limited in all I/O types. One of the worst examples
of constrained performance here is when using unbuffered I/O. To ensure that that writes are fully committed to nonvolatile
regions of the RAID volume, unbuffered I/O bypasses cache (for example by using the Force Unit Access bit in the NVMe
protocol) and the I/O operation will not complete until all the drives in the RAID volume have completed the request to commit
the data. This kind of I/O operation completely negates any advantage of a higher performing drive in the volume.
Care must be taken to match not only the drive vendor, capacity, and class, but also the specific model. Drives from the same
vendor, with the same capacity, and even within the same class, can have different performance characteristics for certain
types of I/O operations. Thus, matching by model ensures that the RAID volume consists of a homogeneous array of drives that
deliver all the benefits of a RAID volume without incurring the additional penalties when one or more drives in the volume are
lower performing.
OptiPlex Small Form Factor Plus 7020 supports RAID with more than one hard drive configuration.

Safety instructions
Use the following safety guidelines to protect your computer from potential damage and to ensure your personal safety. Unless
otherwise noted, each procedure in this document assumes that you have read the safety information that shipped with your
computer.
WARNING: Before working inside your computer, read the safety information that is shipped with your
computer. For more safety best practices, see Dell Regulatory Compliance Home Page.
WARNING: Disconnect your computer from all power sources before opening the computer cover or panels.
After you finish working inside the computer, replace all covers, panels, and screws before connecting your
computer to an electrical outlet.
CAUTION: To avoid damaging the computer, ensure that the work surface is flat, dry, and clean.
CAUTION: You should only perform troubleshooting and repairs as authorized or directed by the Dell technical
support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. See the
safety instructions that is shipped with the product or at Dell Regulatory Compliance Home Page.
CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal
surface, such as the metal at the back of the computer. While you work, periodically touch an unpainted metal
surface to dissipate static electricity which could harm internal components.
CAUTION: To avoid damaging the components and cards, handle them by their edges, and avoid touching the
pins and the contacts.
CAUTION: When you disconnect a cable, pull it by its connector or its pull tab, not the cable itself. Some cables
have connectors with locking tabs or thumbscrews that you must disengage before disconnecting the cable.
When disconnecting cables, keep them evenly aligned to avoid bending the connector pins. When connecting
cables, ensure that the connector on the cable is correctly oriented and aligned with the port.
CAUTION: Press and eject any installed card from the media-card reader.
CAUTION: Exercise caution when handling rechargeable Li-ion batteries in laptops. Swollen batteries should not
be used and should be replaced and disposed properly.

Safety precautions
This section details the primary steps to be followed before performing any disassembly instructions.
Observe the following safety precautions before you perform any installation or break-fix procedures involving disassembly or
reassembly:
● Turn off the computer and all attached peripherals.
● Disconnect the computer from AC power.
● Disconnect all network cables and peripherals from the computer.
● Use an ESD field service kit when working inside any desktop to avoid electrostatic discharge (ESD) damage.
● Place the removed component on an anti-static mat after removing it from the computer.
● Wear shoes with nonconductive rubber soles to reduce the chance of getting electrocuted.
● Unplugging, pressing, and holding the power button for 15 seconds should discharge residual power in the system board.
Standby power
Dell products with standby power must be unplugged before you open the back cover. Systems that are equipped with standby
power are powered while turned off. The internal power enables the computer to be remotely turned on (Wake-on-LAN) and
suspended into a sleep mode and has other advanced power management features.
Bonding
Bonding is a method for connecting two or more grounding conductors to the same electrical potential. This is done by using
a field service electrostatic discharge (ESD) kit. When connecting a bonding wire, ensure that it is connected to bare metal
and never to a painted or nonmetal surface. Ensure that the wrist strap is secure and in full contact with your skin. Remove all
jewelry, watches, bracelets, or rings before grounding yourself and the equipment.
Electrostatic discharge—ESD protection
ESD is a major concern when you handle electronic components, especially sensitive components such as expansion cards,
processors, memory modules, and system boards. A slight charge can damage circuits in ways that may not be obvious, such
as intermittent problems or a shortened product life span. As the industry pushes for lower power requirements and increased
density, ESD protection is an increasing concern.
Two recognized types of ESD damage are catastrophic and intermittent failures.
● Catastrophic – Catastrophic failures represent approximately 20 percent of ESD-related failures. The damage causes
an immediate and complete loss of device functionality. An example of catastrophic failure is a memory module that has
received a static shock and immediately generates a &quot;No POST/No Video&quot; symptom with a beep code that is emitted for
missing or nonfunctional memory.
● Intermittent – Intermittent failures represent approximately 80 percent of ESD-related failures. The high rate of
intermittent failures means that most of the time when damage occurs, it is not immediately recognizable. The memory
module receives a static shock, but the tracing is merely weakened and does not immediately produce outward symptoms
that are related to the damage. The weakened trace may take weeks or months to melt, and in the meantime may cause
degradation of memory integrity, intermittent memory errors, and so on.
Intermittent failures that are also called latent or &quot;walking wounded&quot; are difficult to detect and troubleshoot.
Perform the following steps to prevent ESD damage:
● Use a wired ESD wrist strap that is properly grounded. Wireless anti-static straps do not provide adequate protection.
Touching the chassis before handling parts does not ensure adequate ESD protection on parts with increased sensitivity to
ESD damage.
● Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and workbench pads.
● When unpacking a static-sensitive component from its shipping carton, do not remove the component from the anti-static
packing material until you are ready to install the component. Before unwrapping the anti-static packaging, use the anti-
Working inside your computer
29
Customer’s Internal Use Only – Confidential &amp; Subject to NDA
static wrist strap to discharge the static electricity from your body. For more information about the wrist strap and ESD
wrist strap tester, see Components of an ESD Field Service Kit.
● Before transporting a static-sensitive component, place it in an anti-static container or packaging.
ESD Field Service kit
The unmonitored field service kit is the most commonly used service kit. Each Field Service kit includes three main components:
anti-static mat, wrist strap, and bonding wire.
CAUTION: It is critical to keep ESD-sensitive devices away from internal parts that are insulated and often
highly charged, such as plastic heat sink casings.
Working Environment
Before deploying the ESD Field Service kit, assess the situation at the customer location. For example, deploying the kit for a
server environment is different than for a desktop or laptop environment. Servers are typically installed in a rack within a data
center; desktops or laptops are typically placed on office desks or cubicles. Always look for a large open flat work area that
is free of clutter and large enough to deploy the ESD kit with additional space to accommodate the type of computer that is
being repaired. The workspace should also be free of insulators that can cause an ESD event. On the work area, insulators such
as styrofoam and other plastics should always be moved at least 12 inches or 30 centimeters away from sensitive parts before
physically handling any hardware components.
ESD Packaging
All ESD-sensitive devices must be shipped and received in static-safe packaging. Metal, static-shielded bags are preferred.
However, you should always return the damaged component using the same ESD bag and packaging that the new part arrived
in. The ESD bag should be folded over and taped shut and all the same foam packing material should be used in the original box
that the new part arrived in. ESD-sensitive devices should be removed from packaging only at an ESD-protected work surface,
and parts should never be placed on top of the ESD bag because only the inside of the bag is shielded. Always place parts in
your hand, on the anti-static mat, in the computer, or inside an ESD bag.
Components of an ESD Field Service kit
The components of an ESD Field Service kit are:
● Anti-Static Mat – The anti-static mat is dissipative and parts can be placed on it during service procedures. When using an
anti-static mat, your wrist strap should be snug and the bonding wire should be connected to the anti-static mat and to any
bare metal on the computer being worked on. Once deployed properly, service parts can be removed from the ESD bag and
placed directly on the anti-static mat. ESD-sensitive items are safe in your hand, on the anti-static mat, in the computer, or
inside an ESD bag.
● Wrist Strap and Bonding Wire – The wrist strap and bonding wire can be either directly connected between your wrist
and bare metal on the hardware if the anti-static mat is not required, or connect to the anti-static mat to protect hardware
that is temporarily placed on the mat. The physical connection of the wrist strap and bonding wire between your skin, the
anti-static mat, and the hardware is known as bonding. Use only Field Service kits with a wrist strap, anti-static mat, and
bonding wire. Never use wireless wrist straps. Always be cautious that the internal wires of a wrist strap are prone to
damage from normal wear and tear, and must be checked regularly with a wrist strap tester in order to avoid accidental ESD
hardware damage. It is recommended to test the wrist strap and bonding wire at least once per week.
● ESD Wrist Strap Tester – The wires inside an ESD strap are prone to damage over time. When using an unmonitored kit, it
is a best practice to regularly test the strap prior to each service, and at a minimum, test once per week. A wrist strap tester
is the best method for doing this test. To perform the test, plug the bonding-wire of the wrist-strap into the tester while it
is strapped to your wrist and push the button to test. A green LED is lit if the test is successful; a red LED is lit and an alarm
sounds if the test fails.
NOTE: It is recommended to always use the traditional wired ESD grounding wrist strap and protective anti-static mat
when servicing Dell products. In addition, it is critical to keep sensitive parts separate from all insulator parts while servicing
the computer.

Transporting sensitive components
When transporting ESD sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place
these parts in anti-static bags for safe transport.
Lifting equipment
Adhere to the following guidelines when lifting heavy equipment:
CAUTION: Do not lift greater than 50 pounds. Always obtain additional resources or use a mechanical lifting
device.
1.
2.
3.
4.
5.
Get a firm balanced footing. Keep your feet apart for a stable base, and point your toes out.
Tighten stomach muscles. Abdominal muscles support your spine when you lift, offsetting the force of the load.
Lift with your legs, not your back.
Keep the load close. The closer it is to your spine, the less force it exerts on your back.
Keep your back upright, whether lifting or setting down the load. Do not add the weight of your body to the load. Avoid
twisting your body and back.
6. Follow the same technique in reverse to set the load down.

Commands such as delete and format in the operating system may remove files
from showing up in the file system. However, they can be reconstructed through
forensic means as they are still represented on the physical media. Data Wipe
prevents this reconstruction and is not recoverable.
When enabled, the data wipe option will prompt to wipe any storage devices that
are connected to the computer on the next boot.
By default, the Start Data Wipe option is disabled.

Table 39. System setup options—Passwords menu
Passwords
Administrator Password
The Administrator Password prevents unauthorized access to the BIOS Setup
options. Once the administrator password is set, the BIOS setup options can only
be modified after providing the correct password.
The following rules and dependencies apply to the Administrator Password ● The administrator password cannot be set if computer and/or internal hard
drive passwords are previously set.
● The administrator password can be used in place of the computer and/or
internal hard drive passwords.
● When set, the administrator password must be provided during a firmware
update.
● Clearing the administrator password also clears the computer password (if
set).
Dell Technologies recommends using an administrator password to prevent
unauthorized changes to BIOS setup options.
