Planning Networks

Before configuring a storage system, plan the network structure, including IP addresses and port information.

Planning the Network

Hosts and storage systems can be connected in various modes. For details about connection modes, see "Planning Connectivity" in the Huawei SAN Storage Host Connectivity Guide for XXX. XXX represents a specific operating system, for example, Windows.

SAN Services

Table 3-10 describes how to plan a SAN network.

Table 3-10 Planning a SAN network

Planned Item	Description
Management port of a storage system	The default management port IP addresses of controller A and B are 192.168.128.101 and 192.168.128.102, respectively. The default subnet mask is 255.255.0.0.
Service port of a storage system	Service port that connects to an application server, including the port ID, IP address, and subnet mask. NOTE: The storage system supports bond ports. You must set the link aggregation mode for switch's port connecting to a bond port. For example, on Huawei switches, you must set the static LACP mode for a bond port. Link aggregation modes vary with the switches' manufacturers. For SAN services, an application server and a storage system must use the multi-link mode for interconnection. If the single-link mode is used for interconnection, services will be interrupted upon a link failure. You are advised to install UltraPath. Otherwise, services may be interrupted during the system upgrade process. For details about how to use UltraPath, go to Huawei enterprise support to download its installation guide.
Gateway	Gateways of the storage system and application servers.
Service port of an application server	Service port that connects to the storage system, including the port ID, IP address, and subnet mask.
Initiator name	Initiator for an application server to connect to the storage system.
iSCSI CHAP	Plan iSCSI CHAP to control access to the storage system. CHAP is a method of verifying the identity of the peer using a 3-way handshake. This verification is based on a ciphertext or cipher key. During the establishment of a link, the authenticator sends a random challenge message to the peer. The peer encrypts the random challenge message using the password and algorithm and responds with the ciphertext. The authenticator checks the response against its own ciphertext obtained by encrypting the random challenge message using the peer's password and algorithm that have been saved. If the two ciphertexts match, the authentication is acknowledged. Otherwise, the connection is terminated. After CHAP authentication is enabled on the storage system, you must enter the CHAP user name and password when accessing the storage system from an application server. When planning CHAP, note the following: User name for CHAP authentication The name must contain 4 to 223 characters. The name only contains letters, digits, and special characters. Special characters include: !"#$&%'()+,-./:;<=>?@[\]^_`{\|}~ The first character must be a letter or digit. Password for CHAP authentication The password must contain 12 to 16 characters. The password must contain three of the following four types of characters: Uppercase letters Lowercase letters Digits Special characters (including space) !"#$&%'()+,-./:;<=>?@[\]^_`{\|}~ The password must not be the same as the CHAP user name or the reverse of the user name. Mapping between CHAP user accounts and initiators CHAP user accounts must be created and assigned to corresponding initiators. NOTE: For details about how to enable CHAP authentication, refer to Creating an Initiator.

VM Services

Table 3-11 describes how to plan a VM network.

Table 3-11 Planning a VM network

Planned Item	Description
Management port of a storage system	The default management port IP addresses of controller A and B are 192.168.128.101 and 192.168.128.102, respectively. The default subnet mask is 255.255.0.0.
Management port of a VM	After a VM is installed, the management port of the storage system is used to manage the VM by default. The maintenance port of the storage system cannot be used to manage the VM. To assist with VM management using RDP (Windows) or SSH (Linux), configure the management port IP address of the VM and subnet mask in the VM.
Service port of a VM	VMs use service ports to provide VM services. After VMs are installed, you must add service ports to the VMs, including the port IDs and IP addresses configured in the VMs.
Gateway	Gateway used by VMs to provide services.
