RAID (Redundant Array of Independent Disks)
For optimal performance when configuring drives as a RAID volume, Dell Technologies recommends drive models that are
identical.
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 determine the performance, which increases variability and results in inconsistent latencies. This variability is
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 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, results in the I/O operations completing only as fast as the slowest drive. While
this does not suffer 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 writes are fully committed to non-volatile 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.
RAID 5 as the most common and best "all-round" RAID level, RAID 5 stripes data blocks across all drives in an array (at least 3
to a maximum of 32), and also distributes parity data across all drives. In the event of a single drive failure, the system reads
the parity data from the working drives to rebuild the data blocks that were lost. RAID 5 read performance is comparable to
that of RAID 0, but there is a penalty for writes since the system must write both the data block and the parity data before the
operation is complete. The RAID parity requires one drive capacity per RAID set, so usable capacity will always be one drive less
than the total number of drives in the configuration. Not suited for applications requiring many small random data writes due to
poor random data write performance.
RAID 10 (sometimes referred to as RAID 1+0) combines RAID 1 and RAID 0 to offer multiple sets of mirrors striped together.
RAID 10 offers good performance with good data protection and no parity calculations. RAID 10 requires a minimum of four
drives, and usable capacity is 50% of available drives. It should be noted, however, that RAID 10 can use more than four drives
in multiples of two. Each mirror in RAID 10 is called a "leg" of the array. A RAID 10 array using, say, eight drives (four "legs," with
four drives as capacity) will offer extreme performance in both spinning media and SSD environments as there are many more
drives splitting the reads and writes into smaller chunks across each drive. Ideal for applications requiring many small random
data writes due to superb random data write performance.
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 volumes are consisted 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.

System management features
Dell commercial systems come with a number of systems management options that are include by default for In-Band
management with our Dell Client Command Suite. In-Band management meaning that the Operating System is functional and
the device is connected to a network so that it can be managed. The Dell Client Command Suite of tools can be leveraged
individually or with a systems management console like SCCM, LANDESK, KACE, etc.
We also offer Out-of-Band management as an option. Out-of-band management is when the system does not have a functional
operating system or is turned off and you still want to be able to manage the system in that state.
Dell Client Command Suite for in-band systems management
Dell Client Command Suite is a free toolkit available for download, for all Latitude Rugged tablets at dell.com/support, that
automates and streamlines systems management tasks, saving time, money, and resources. It consists of the following modules
that can be used independently, or with a variety of systems management consoles such as SCCM.
Dell Client Command Suite's integration with VMware Workspace ONE Powered by AirWatch, now allows customers to manage
their Dell client hardware from the cloud, using a single Workspace ONE console.
Dell Command | Deploy enables easy operating system (OS) deployment across all major OS deployment methodologies and
provides numerous system-specific drivers that have been extracted and reduced to an OS-consumable state.
Dell Command l Configure is a graphical user interface (GUI) admin tool for configuring and deploying hardware settings in a
pre-OS or post-OS environment, and it operates seamlessly with SCCM and Airwatch and can be self-integrated into LANDesk
and KACE. Simply, this is all about the BIOS. Command l Configure allows you to remotely automate and configure over 150+
BIOS settings for a personalized user experience.
Dell Command l PowerShell Provider can do the same things as Command l Configure, but with a different method.
PowerShell is a scripting language that allows customers to create a customized and dynamic configuration process.
Dell Command l Monitor is a Windows Management Instrumentation (WMI) agent that provides IT admins with an extensive
inventory of the hardware and health-state data. Admins can also configure hardware remotely by using command line and
scripting.
Dell Command | Update (end-user tool) is factory-installed and allows admins to individually manage and automatically
present and install Dell updates to the BIOS, drivers, and software. Command l Update eliminates the time-consuming hunting
and pecking process of update installation.
Dell Command l Update Catalog provides searchable metadata that allows the management console to retrieve the latest
system-specific updates (driver, firmware or BIOS). The updates are then delivered seamlessly to end-users using the
customer's systems management infrastructure that is consuming the catalog (like SCCM).

Dell Command | vPro Out of Band console extends hardware management to systems that are offline or have an un-
reachable OS (Dell exclusive features).
Dell Command | Integration Suite for System Center - This suite integrates all the key components of the Client Command
Suite into Microsoft System Center Configuration Manager 2012 and Current Branch versions.

Keyboard shortcuts of Precision 7780
NOTE: Keyboard characters may differ depending on the keyboard language configuration. Keys that are used for shortcuts
remain the same across all language configurations.
Some keys on your keyboard have two symbols on them. These keys can be used to type alternate characters or to perform
secondary functions. The symbol that is shown on the lower part of the key refers to the character that is typed out when the
key is pressed. If you press shift and the key, the symbol that is shown on the upper part of the key is typed out. For example, if
you press 2, 2 is typed out; if you press Shift + 2, @ is typed out.
The keys F1-F12 at the top row of the keyboard are function keys for multi-media control, as indicated by the icon at the bottom
of the key. Press the function key to invoke the task represented by the icon. For example, pressing F1 mutes the audio (refer to
the table below).
However, if the function keys F1-F12 are needed for specific software applications, multi-media functionality can be disabled
by pressing
example, mute audio by pressing Fn + F1.
NOTE: You can also define the primary behavior of the function keys (F1–F12) by changing Function Key Behavior in
BIOS setup program.
