expansion requirements. Currently, open-source distributed Block Storage includes CEpH, glusterfs, and sheepdog. Compared with CEpH, the biggest advantage is that the Code is short and well maintained, and the hack cost is very small. Sheepdog also has many features not supported by CEpH, such as multi-disk and cluster-wide snapshot. In this article, Japanese NTT researchers compared sheepdog, glusterfs, and CEpH Read and Write Performance in various circumstances. This test was announced at th

Figure 1 illustrates: The office network OpenStack uses 2 switches, the 10.40.40.2 is 24 port 10.40.40.6 is 48 port, manages the network segment to 10.40.40.2vlan1002 the virtual machine The public network segment to connect 10.40.40.6 VLAN1100. Because the 10.40.40.6 can support one interface to configure multiple network segments, another switch is not supported and is also designed to be scaled out in the future.Figure 2 Figure 3 illustrates: The K
