ZFS Best Practices Guide
-
Size memory requirements to actual system workload:
-
With a *known* application memory footprint, such as database application, you might cap the ARC size so that the application will not need to reclaim its necessary memory from the ZFS cache.
-
- When a known amount of memory is always required by an application. Databases often fall into this category.
- On platforms that support dynamic reconfiguration of memory boards, to prevent ZFS from growing the kernel cage onto all boards.
- A system that requires large memory pages might also benefit from limiting the ZFS cache, which tends to breakdown large pages into base pages.
- Finally, if the system is running another non-ZFS file system, in addition to ZFS, it is advisable to leave some free memory to host that other file system's caches.
Memory and Dynamic Reconfiguration Recommendations
The ZFS adaptive replacement cache (ARC) tries to use most of a system's available memory to cache file system data. The default is to use all of physical memory except 1 GB. As memory pressure increases, the ARC relinquishes memory.
Consider limiting the maximum ARC memory footprint in the following situations:
The trade off is to consider that limiting this memory footprint means that the ARC is unable to cache as much file system data, and this limit could impact performance.

davidmerrick# Run ZFS on a system that runs a 64-bit kernel
# One GB or more of memory is recommended.
# Approximately 64 KB of memory is consumed per mounted ZFS file system. On systems with 1,000s of ZFS file systems, provision 1 GB of extra memory for every 10,000 -
