RAID (Redundant Array of Independent Disks)
For optimal performance when configuring drives as a RAID volume, Dell Technologies recommends identical drive models.
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 split 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 pronounced for write operations, and it can be problematic for latency- sensitive applications. 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-around” RAID level, RAID 5 strips 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 many more drives are 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 consist 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.

• Precision 7780 supports RAID with more than one solid-state drive configuration.

Keyboard shortcuts of Precision

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 Fn + Esc. Subsequently, multi-media control can be invoked by pressing Fn and the respective function key. For example, mute audio by pressing Fn + F1.

NOTE: You can also define the primary behavior of the function keys (F1–F12) by changing the Function Key Behavior in the BIOS setup program.

Table 32. List of keyboard shortcuts

NOTE: Toggle to cycle the keyboard backlight status through off, low- backlight, and high-backlight

F6| Decrease brightness
F7| Increase brightness
F8| Switch to external display Search
F10| Print screen
F11| Home
F12| End

The Fn key is also used with selected keys on the keyboard to invoke other secondary functions.
