the actual virtual machines were still working, in short, an accident occurred. Therefore, we recommend that you configure the management network redundancy to avoid this happening.
So we can draw the following conclusions.
Management traffic-This interface is mainly used to configure the vsphere ha, the management of the network heartbeat transmission, if not checked, means that no vsphere ha no heartbeat network, will be configured to fail;
Other network functions are as follows:

I. Introduction to ISCSI
ISCSI, internet SCSI, also known as IP-SAN, is a standard developed by IETF to map SCSI data blocks into Ethernet packets. ISCSI is a TCP/IP-based protocol used to establish and manage the connection between IP storage devices, hosts and clients, and create a storage

Requirement: Share the/dev/sdc on the iscsi-target server for mounting and use from the windows and linux clients respectively.
Iscsi-target server IP Address: 192.168.10.50
First, the concept of iSCSI
iSCSI is a standard for data block transmission on Internet protocols, especially Ethernet, which is a new storage technology based on IP storage theory, which combines SCSI interface technology widely used in storage industry with IP network technology, You can build a SAN storage area network on an IP network, simply put, iSCSI is a
Recent experiments on VMware ESXi and Vcenter, in the experiment, need to use storage, so study the Openfiler open source storage software, the relevant configuration is now the following record:
First of all, I downloaded the openfiler ISO CD, installed in the virtual machine, the installation is very simple, and the same as the Linux installation steps, do not do too much introduction.
When the Openfiler is installed, we can log on to the Open
Use iSCSI Target to create centralized security storage (1)
ISCSI is a block-level protocol used to share original storage devices through TCP/IP networks, you can use an existing IP address and ethernet address, such as a nic, vswitch, or vro, to share and access storage through the iSCSI protocol. ISCSI target is a r

Introduction iSCSI (Internet SCSI) technology developed by IBM Research, is a hardware device used by the upper layer of the IP protocol can run the SCSI instruction set, which can be implemented on the IP network to run the SCSI protocol, Allows routing to be routed on such high-speed Gigabit Ethernet. iSCSI technology is a new storage technology that combines existing SCSI interfaces with Ethernet (Ethern
iSCSI is a SAN device and the SAN device is primarily a space for providing Server storage. iSCSI (Internet SCSI) is an ip-based data storage device compared to a traditional SAN, which is a fiber-optic transmission medium. It makes it easier for him to apply in the enterprise. 1. The normal network card can be used as iSCSI target but the disadvantage is that it
