Create Block-optimized Storage networks in PowerStore Manager

Once you have configured the Top-of-Rack (ToR) switches with iSCSI, NVMe/TCP, or Replication and Block import networks, the networks must also be created in PowerStore Manager.

This topic describes steps to configure the iSCSI, NVMe/TCP, and Replication and Block Import networks in PowerStore Manager. For steps to configure networks for Network Attached Storage (NAS) networks, see Create NAS networks in PowerStore Manager.

Get the completed Network configuration worksheet for Storage services.

The following Network configuration worksheet for Storage services has been completed with the network resources that are used in this guide. If the Top-of-Rack switches were not configured with the resources that are used in this guide, complete a new Network configuration worksheet for Storage services with the information relevant to your environment. To download a blank worksheet, see Network configuration worksheet for Block-optimized Storage services (blank).

Once you have configured the Cluster network on the switch, Cluster network configuration is automated in PowerStore Manager, and no further action is required.

By default PowerStore Manager assigns iSCSI, NVMe/TCP, and Replication to the Default Storage Network. You can change the Default Storage Network purposes in PowerStore Manager.

Table 1. Network configuration worksheet for additional Block-optimized storage services (completed)Lists the resources that are reserved in the sample configuration for the iSCSi, NVMe/TCP, and Replication and Import networks.
Resource iSCSI NVMe/TCP Replication and Block Import
Storage Network Name iSCSI_Network NVMe_Network RepBlockImport_Network
Purpose

A storage network can be purposed for iSCSI, NVMe/TCP, Replication (and Block Import), or all the protocols.

Storage (iSCSI) Storage (NVMe/TCP) Replication
(Optional) VLAN ID

For better security and performance, it is recommended that you specify a unique VLAN ID for each type of network.

If you are deploying into a single VLAN, ensure that you configure a unique subnet for the Management and each Storage network.

Use the same VLAN IDs that were used to configure your Storage networks on the switch.

200 300 400
Netmask/Prefix Length 24 24 24
Gateway 192.168.2.1 192.168.3.1 192.168.4.1
Storage Network IP addresses

You must reserve a minimum of two IP addresses for each Storage network you are adding. (One IP address per node.)

192.168.2.11-12 192.168.3.11-12 192.168.4.11-12
(Optional) Global Storage Discovery IP

It is recommended that you choose to create this IP address. It is used as the single highly available floating IP address for hosts to discover storage from your cluster.

192.168.2.10 192.168.3.10 192.168.4.10
Map Storage for Appliance/Network Interface (Include the port or Link Aggregation (LACP bond) for each appliance to which the storage is mapped). Port 2 on I/O Module 0 Port 0 on I/O Module 0 Port 2 on I/O Module 0
Network MTU Size You can provide an MTU size between 1280-9000 bytes.
NOTE:It is recommended to set the MTU size to 9000.
9000 9000 9000
  1. From PowerStore Manager go to the Settings > Network IPs > Storage tab.
  2. Click Create.
  3. Enter the network resources into the Create Storage Network wizard and select Next. When mapping the ports to the network, select the checkbox next to the name of the first port over which the storage traffic runs.
    PowerStore Manager automatically maps the network to both the port that you selected, and the corresponding port on the other node.
  4. Repeat steps 1 - 3 for each network that you are adding.
  5. To validate the Storage network was successfully configured:
    1. Go to the Hardware page.
    2. Select the appliance name and go to the Ports page.
    3. Locate the port on which you created the Storage network in the Node-Module-Name column.
    4. The Link State should be green, and the network should appear in the Mapped for Storage column.
    5. Locate the corresponding port on the other appliance node, to validate that the Link State is green, and the Storage network appears in the Mapped for Storage column.
