Server/Cluster Specification
Log devices boost write performance by committing a copy of all data writes to fast NVMe/SSD storage first which enables the system flush data out to HDD devices asynchronously and more efficiently in larger blocks.
Storage Configuration
Compression % indicates the amount of additional usable capacity is gained due to data compression. If the data is pre-compressed such as images, video or pre-encrypted files set this to 0%.
Reserved free-space (overhead) indicates the amount of space that will not be used in order to avoid performance degradation. Large archive configurations which are generally write-once-read-many can set this to a low value like 5%. Database and server/desktop virtualization storage should set this to a higher value like 20%.
Reserved drive slots indicates the percentage of drive bays that should remain empty for future expansion. This is helpful for starting the cluster with a larger number of servers that are partially populated.
