WekaFS does not use any internal memory to temporarily cache write data to the underlying storage system. All writes are commited directly to the storage disk, and protected via WekaFS Distributed Data Protection (4+2 in this case). There is no need for any RAM battery protection. In an event of a power failure a write in transit would not be acknowledged.
The system under test consisted of the 8 client servers and 6 storage servers. The 6 storage servers each have 2x dual-port network interfaces connected to a 200GbE switch. The 8 load generating client servers each have a dual-port network interface also connected to a 200GbE switch.
None
One of the 8 client servers acted as benchmark's prime client to initiate the tests. The benchmark load is distributed accross the 8 Dell R7525 client servers using a single mount point per client.
None
The solution under test was a standard WekaFS cluster in dedicated server mode. The solution will handle both large file I/O as well as small file random I/O and metadata intensive applications. No specialized tuning is required for different or mixed use workloads. None of the components used to perform the test were patched with Spectre or Meltdown patches (CVE-2017-5754, CVE-2017-5753, CVE-2017-5715).
