Server & Cluster Specification

201 All-flash meta-data pool devices are generally required for configurations using HDDs as the data device media as HDDs are too slow for filesystem meta-data storage.
204 Boost read & write performance through write-ahead-logging (WAL) and metadata offload (MDB) to SSD/NVMe media.
10010 Our general recommendation is to have a 1:1 ratio where a GB of RAM is added to the server for each TB of usable capacity. For most backup and archive configurations the required RAM requirements are lower and a reduced ratio may be used.
10010 For HDD based systems the mirrored SSD cache capacity should be between 2% and 4% of the total HDD capacity.

Storage Configuration

8010 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%.
4010 Reserved free-space (backfill space) indicates the amount of space that will not be used in order to avoid performance degradation and ensure uptime in the event of a server outage.
900 Reserved drive slots indicates the percentage of drive bays per system that should remain empty for future expansion.
