Hello mailing list,
I have got two questions:
1.) I have set-up a softraid (raid level 0) with mdadm using two M.2
modules. For one module the throughput is ~350MB/s (no mdadm) for two
modules the throughput is ~500MB/s which is less than factor 1,5 of the
throughput of a single drive. The filesystem used is ext4. Is there
someone having some values for comparison? For me the throughput gain
seems to be too little. The test was done using a HP Z840 workstation.
2.) We want to configure a softraid (raid level 0) with mdadm which can
be used from within Linux but also it should be possible to write data
to the raid w/ DMA directly from the FPGA which is also connected to the
PCIe bus as a slave as well as the M.2 modules. How can that be achieved
using existing kernel infrastructure?
Many thanks for helpful replies
Eric
