For PowerEdge R660 servers, each server has 14 NVMe devices directly connected. This configuration is not a balanced configuration in terms of NUMA domains because it has six drives under CPU 1 and eight drives under CPU 2. For the configuration characterized, two PowerEdge R660 servers fully loaded with Dell AG 3.84TB (PM1743) E3.S PCIe5 devices were used. Nevertheless, any NVMe device supported on the PowerEdge R660 server is also supported for these NVMe nodes.
In the current configuration, our partner Kalray divided each file system block of 8 MiB into 32 subblocks of 256 KiB each. This division might have an impact on space efficiency for small files and perhaps affect performance for some benchmarks. Updates to the solution will include more investigation.
