I am trying to create a 5 node cluster using 1 Tb SSD disks with 2 OSD on each server.Each server will have 10G NIC. SSD disks are of good quality and as per label it can support ~300 MBps
What are the limiting factor that prevents from utilizing full speed of SSD disks? Disk controllers are 3 Gbps,so if i am not wrong this is the maximum i can achieve per host.Can ceph distribute write parallely and over come this limit of 3Gbps controller and thus fully utilize the capability of ssd disks. I have a working 3 node ceph setup deployed using ceph-deploy using latest firefly and 3.16 kernel but this is on low quality SATA disks and i am planning to upgrade to ssd can some one please help me in understanding this better.
