Other Planning Items
Plan the power distribution, network allocation, user management schemes, and compatibility solutions relevant to the storage devices.
Power Distribution Planning
Before installing devices, work out a power distribution plan for optimal device security.
Power Distribution Principles
Table 3-8 lists the power distribution principles that the storage system must comply with.
Scenario |
Principle |
|---|---|
Equipment room |
The power supply of a cabinet has a backup line. |
The input voltages to a cabinet must be the same. |
|
The power distribution unit (PDU) of a cabinet supports two independent power supplies. Therefore, the failure of one power supply does not affect the other power supply. |
|
The rated load traffic of the power cables meets the maximum operating power of the cabinets and devices. The breaker and power cable match design requirements. |
|
The power input terminal of a cabinet must be convenient, safe, and reliable for connection. |
|
Power distribution inside a cabinet |
Power input lines of the device whose power input is redundant connect to different branches of the power supply. |
The devices in the cabinet can be effectively protected against overcurrent and short circuit. |
|
The power distribution of the cabinet supports online maintenance of devices (excluding the devices that require device-level backup and auxiliary devices that do not affect the services in the cabinet). |
|
It is recommended that you configure a PDU in the cabinet. Connect the external power supply to the PDU, then the PDU supplies power to the devices in the cabinet. |
|
Devices in a cabinet should obtain power from the PDU of the cabinet rather than from another cabinet. |
|
The actuator directions of the breakers in a PDU are the same. If the actuator operates vertically, moving the actuator upward connects the power supply, while moving the actuator downward disconnects the power supply. If the actuator direction is horizontal, moving the actuator to the left disconnects the power supply, while moving the actuator to the right connects the power supply. |
|
The power cables and signal cables should be separately routed in the cabinet. The distance between these two kinds of cables should be greater than 3 cm. |
|
Each circuit breaker in the PDU can only connect one load. |
|
The power of the devices in the cabinet corresponds to the rated current of the protection components. The devices and system enclosures of the same model can obtain power from the protection components with the same rated current. |
|
When a breaker that needs onsite cable connection is vertically installed, feed cables from the top to the bottom of the breaker. |
Network Allocation Planning
Before installing devices, the network administrator must plan IP addresses and network parameters.
Data Plan
Before performing the initial configuration, plan and record IP addresses and related parameters for the storage system. This helps ensure a smooth configuration later.
A controller enclosure supports IPv4 and IPv6 addresses. Table 3-9 and Table 3-10 list the IP addresses assigned to the system management network ports on the controller enclosure.
IPv4 Address |
Subnet Mask |
Gateway |
|---|---|---|
Management network port 0 on the controller:_________________ |
___________ |
___________ |
Management network port 1 on the controller:_________________ |
___________ |
___________ |
IPv6 Address |
Prefix |
Gateway |
|---|---|---|
Management network port 0 on the controller:_________________ |

Management network port 1 on the controller:_________________ |

- You need to plan IP addresses and network parameters for the storage system each time when a system bay is added.
- When the storage system is configured with a key management server, you need to plan cluster IP addresses for the key management server to ensure the network connectivity between the key management server clusters.
- The key management server supports only the IPv4 address. To ensure normal communication between the storage system and the key management server, ensure that IPv4 addresses are used for both the storage system and the key management server.
Table 3-11 and Table 3-12 list alarm policy parameters.

User Account Planning
Plan management accounts with different operation and maintenance permissions and configure passwords in compliance with password policies to ensure security. For details about the accounts, see the OceanStor V500R007 Account List. If you have deployed an external key management server and want to change its management account and password, refer to its user guide for details or contact technical support engineers of its vendor.
Compatibility Solution Planning
Before installing a storage system, plan a compatibility solution to ensure smooth installation and configuration of storage devices.
The compatibility information to be planned includes, but not limited to the following: server models, operating systems, HBA models and quantity, multipathing versions, switch models and versions, cluster software, backup software. You can use OceanStor Interoperability Navigator to query detailed compatibility information.
