To improve network reliability and security requirements, we may want to separate the control and storage networks of openstack, that is, to configure the iscsi private network. Taking the kvm + lvm + iscsi ubuntu environment as an example, consider a simple deployment model, a computing node (nova-compute), a storage

Different storage vendors have different iscsi configurations. Currently, three approaches are available: 1) directly add the target IP address on the host, and then discover the target. The UIT low-end server architecture storage has been discontinued) 2) some users need to add the iscsi initiator number on the target

theory that can be used is less than the actual one.LUNsYou can also connect multiple logical devices (such as disks, volume groups, and so on) under each SCSI target device (target), so that each logical device has a LUN (Logical Unit number) to identify itself, in order for the system to differentiate between each logical device. Each SCSI ID has a maximum of 32 LUNs, which starts from 0 by default (although 0 is occupied), and each LUN corresponds to a logical device.SCSI Communication Model

Induction:LinearContinuous storage of "arrays"Advantage: Fast access (element can be directly located)Cons: Insertion of deleted elements is slow (because you want to move other elements), space is usually limitedDiscrete storage "linked list"Advantage: No space limit, insert delete element quicklyCons: Access speed is slow (to one traversal, one for one)Application of linear structure:1.

In general, small companies have lower overall storage requirements and fewer users, so the capacity and performance requirements are less stringent. and medium-sized storage companies pay more attention to whether the price is reasonable, the use is convenient. The midrange disk array has a limited number of disks, and prices are much cheaper than those of large

The storage structure of the graph holds two types of information:1) Vertex data2) The relationship between vertices Sequential storage: Any two vertices may be associated, and the relationship between elements cannot be represented by the physical location of the element in the store.Multi-linked list: Similar to a tree, wasting storage units
