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.

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