Hi,
I have 16 SAS disk on a LSI 9266-8i and 4 Intel 520 SSD on a HBA, the
node has dual 10G Ethernet. The clients are 4 nodes with dual 10GeB, as
test I use rados bench on each client. The aggregated write speed is
around 1,6GB/s with single replication.
In the first configuration, I had the SSDs on the raidcontroller as
well, but then I saturated the PCIe 2.0 x8 interface of the
raidcontroller, therefore I use a second controller for the SSDs.
