Enterprise cloud storage management
Enterprise cloud storage management interface
Click [storage] to enter the enterprise cloud storage management interface in the console menu bar in this screen to view the current state of enterprise cloud storage, storage usage, alarm information, as well as information on memory system maintenance
1. Virtual Storage Management
Virtual Storage Manager
can manage virtual storage configuration maintenance of storage volume, hard disk, virtual disk sharing, virtual iSCSI, as well as virtual advanced configuration
1.1 storage volume management
Click the virtual storage volumes already exist, into a virtual storage volumes detail page, you can view the information capacity of the storage volume, basic information, operating status, you can also delete, and manage storage space on the storage volume
Create a storage volume - Click to create volumes in storage volume management interface to enter the interface to create virtual storage volumes, if it is the case of multi-volume required at least every three hosts in a storage volume.
Storage volume expansion - Click in the storage volume management page [expansion] will add the newly added disk to an existing host or virtual storage volumes
存储卷扩容—配置待扩容的硬盘，系统会自动设置硬盘用途，也可以手工配 置硬盘用途
存储卷扩容—配置好硬盘之后下一步进入扩容配置信息确认页面，可以看到 扩容操作对原存储卷的影响，点击确认之后扩容完成
1.2 虚拟存储网络管理
虚拟存储网络配置—在虚拟存储管理界面点击【高级配置】–【虚拟存储网 络配置】中配置虚拟存储网络组网，接口，IP参数
虚拟存储网络配置—配置管理虚拟存储通信网络模式以及存储通信网口及IP 地址
虚拟存储数据平衡
数据平衡
虚拟存储运在行过程中，主机间的各磁盘可能使用的不均匀，此时就需要用到存 储的平衡技术，让各主机，各磁盘使用量达到均衡，并且底层的数据发生过迁移 尽量不影响到虚拟机业务的运行。
数据平衡设置
1.2 虚拟存储硬盘管理
虚拟存储硬盘管理 硬盘管理可以查看加入虚拟存储的所有的磁盘状态和容量使用信息，当磁盘出现 故障时可以直观的查看到并进行相应处理。
1.3 虚拟ISCSI 管理
虚拟iSCSI管理
虚拟iSCSI是可以在虚拟存储中开启iSCSI存储服务器，对外提供iSCSI服务，可以让其他集群或者主机连接挂在iSCSI存储进行使用
配置虚拟iSCSI服务器
选择一个虚拟存储卷进行iSCSI服务器配置
配置iSCSI认证信息
配置iSCSI接入网口以及接入IP地址
管理网口复用的情况下不能用于iSCSI服务器接口， 推荐使用虚拟存储网口对 外提供iSCSI服务
创建虚拟iSCSI硬盘
iSCSI服务器配置完成之后即可在创建iSCSI磁盘，选择对应的存储卷，配置硬盘大小，可以配置可访问客户端，如果是集群使用，择需要勾选允许多客户端同时接入,创建完成之后企业云即可对外提供iSCSI服务
2. 外置存储管理
Enterprise Cloud supports the addition of external memory used to store data, you can add NFS, FC, iSCSI storage to enterprise cloud for storing data, which NFS due to poor performance, can only store data for virtual machine backup, can not be created run virtual machines.
Storage management - other storage - storage Click [Add] to show different types of storage can be added, where local storage is not added to the virtual storage local hard disk.
2.1 iSCSI Storage Management
iSCSI 是一种端到端的协议，用于在IP网络中传输存储I/O 数据块。
iSCSI 协议定义了在TCP/IP 网络发送、接收block（数据块）级的存储数据的规则和方法，将SCSI 命令和数据封装到TCP/IP 包中再通过网络转发。
Adding iSCSI storage need to set up iSCSI server connectivity in enterprise cloud configuration, add the iSCSI server. Configured automatically discovers the iSCSI iSCSI disk server when connection configuration, save the configuration.
ISCSI target to be discovered CHAP authentication is configured, you can click Save after certification.
After authentication by adding disks to be certified by the
Adding iSCSI storage has been certified by selecting the host needs to connect to, and will format the iSCSI disk after determining that added to the enterprise in the cloud
2.2 FC Storage Management
FC采用基于IP的光纤通道（FCIP）来连接TCP/IP 网络上的存储设备，FCIP 通过在IP 网络的两个端点之间建立一条隧道来传输光纤通道数据。
通常通过密集波分多路复用和暗光纤来建立存储区域网。
aCloud automatically discovers connected on a host of FC storage, but also need to add it to aCloud logical storage in order to use.
2.3 NFS storage management
NFS (Network File System) that is a network file system, FreeBSD is a supported file system, which allows a TCP / IP network to share resources between computers on the network.
In the application of the NFS, the NFS client's local application can transparently read and write files located on a remote NFS server, just like access local files.
Due to poor performance of NFS, NFS storage for virtual machine backups only, can not be used to create running virtual machine operations.
