The internal secrets of large data centers cost as much as 0.145 billion US dollars (1) Most applications and cloud services are inseparable from data centers. But what factors have created such core systems in the online world? Equinix, a global networking and data center company, showed the world its Data Center (costing up to $0.145 billion) created in yinggrunsau last week) -The glass and steel multi-storey building will initially have thousands

CEPH displays creating when creating one or more collocated groups, and when created, the OSD in the acting set of its collocated group will be interconnected; Once the interconnect is complete, the Collocated group state should become active+clean, meaning that the Ceph client can write data to the colocation group.2.

array disk.By default, we use a group to group resources, and start the resource in the order from the top down, and if the intermediate resource stops unexpectedly, the cluster shuts down the following resources and starts from the middle, because a resource cannot exist in multiple resource groups, which of course does not meet the requirements.WORKAROUND: When the Configure is configured, group the VIP and array into a resource group, using the Order command to define the boot order, namely:
