This chapter contains the following information.

Topics:

• PowerStore X model Network Setup Preparation Worksheet

• Initial Configuration Worksheet

PowerStore X model Network Setup Preparation

Worksheet

Work with your network administrator to complete the Network Setup Preparation Worksheet to reserve the necessary

information to configure the switches.

It is recommended that you work with your network administrator to also complete the Initial Configuration Worksheet while

completing the Network Setup Preparation Worksheet.

For a sample of a Network Setup Preparation Worksheet completed for Dell EMC PowerSwitch Series S4148-ON switches see,

PowerStore X model Network Setup Preparation Worksheet completed example.

Table 2. PowerStore X model Network Setup Preparation Worksheet (blank)

Step Step details Notes

1. Print this table to record the reserved resources.

2. Print out the Initial Configuration Worksheet to record the additional network resources you will need to create

networks in PowerStore X model the first time you create a cluster.

3. Determine which of the Top-of-Rack (ToR) switch ports will be connected to the PowerStore X model appliance base

enclosure nodes.

At a minimum, ports 0 and 1 of the 4-port card must be connected to the ToR switches. When cabling the nodes to the

ToR switches:

● Port 0 and Port 1 on the same node must connect to opposite switches

● Port 0 on Node A, and Port 0 on Node B must connect to opposite switches

● Port 1 on Node A, and Port 1 on Node B must connect to opposite switches

Record the ToR switch ports required to connect to:

Node A, Port 0 to

Node A, Port 1 to

Node B, Port 0 to

Node B, Port 1 to

4. Record the switch port to use for discovery while

configuring your switches.

5. Record the VLAN IDs that will be used for system management:

Remote Discovery (untagged)

Management (tagged)

6. Record the VLAN IDs that will be used for production:

Storage network (tagged)

7. Reserve and record the IP addresses necessary to configure the switch below:

Management IP address for switch 1

Management IP address for switch 2

Default gateway

NTP server

8. Dell EMC supports deploying PowerStore X model with two Top-of-Rack (ToR) switches with a layer 2 interconnect

link.

Choose which type of layer 2 interconnect you will use:

Highly Recommended: Multi-chassis Link Aggregation Group (MC-LAG)

If you will be using MC-LAG, record the ports you will use to connect the switches together.

Switch to switch port pair 1

Switch to switch port pair 2

Alternatively, L2 uplinks without MC-LAG

9. If using MC-LAG, enter the Domain ID.

10 If using VLT for the Layer 2 interconnect, record the:

VLT MAC address to use for both switch 1 and switch 2.

Use the same VLT MAC address for switch 1 and switch

2.

NOTE: You cannot use all zeros

(00:00:00:00:00) for the VLT MAC address.

VLT priority for switch 1

VLT priority for switch 2

11. Record the ports on the ToR switches that will be used to connect to the uplinks.

Uplink A to ToR 1

Uplink B to ToR 1

Uplink A to ToR 2

Uplink B to ToR 2

12. Record the port channel ID used for connectivity between the ToR switches, and the uplinks.

If deploying with MC-LAG, enter the port channel ID for

the uplink.

Only a single port channel ID is required for MC-LAG.

Alternatively, record the uplink port channel IDs required for L2 uplinks without MC-LAG.

L2 uplinks without MC-LAG connectivity requires two port channel IDs.

1. Port channel ID for L2 uplinks without MC-LAG

2. Port channel ID for L2 uplinks without MC-LAG

13. As a best practice it is recommended to add a spanning tree protocol to the ToR switches. Record the spanning tree

protocols to set on each switch.

Prepare to configure switches and networks 9

14. Once you have completed steps above, you have the necessary information to configure the switches. Continue to

work with your network administrator to complete the Initial Configuration Worksheet now to ensure that:

● Your network configuration on the switch aligns with the network configuration that will be done in PowerStore X

model.

● You reserve the necessary network resources to complete deployment of PowerStore X model networks.

15. Determine if you will use a direct connection or a remote connection to discover your PowerStore.

Once you have successfully discovered your PowerStore, you will be guided through the Initial Configuration Wizard

to create your PowerStore cluster.

Initial Configuration Worksheet

Work with your network administrator to complete the Initial Configuration Worksheet. Once completed the worksheet will

provide the necessary information to setup up the networks during initial configuration of PowerStore X model.

It is recommended that you work with your network administrator to also complete the Network Setup Preparation Worksheet

while completing the Initial Configuration Worksheet.

NOTE: Once set, the drive failure

tolerance level for an appliance cannot be

changed.

Networks

Your cluster requires a dedicated set of IP addresses for each type of network.

NOTE: VLAN information for management, storage, and vMotion networks are optional and default to 0. It is a marker

used to indicate that the network traffic is not tagged and native VLAN is applied through the switch. For better security

and performance, it is recommended that you specify a unique VLAN information for each type of network.

If you are deploying into a single VLAN, it is recommended that you configure a unique subnet for each type of network.

Cluster IP Address

PowerStore X model: Network configuration

requirements

This chapter includes the following information.

Topics:

• Top-of-Rack (ToR) switch connectivity options and requirements

• PowerStore X model networks

• PowerStore X model networks VLAN options

• IP addresses for network configuration

Top-of-Rack (ToR) switch connectivity options and

requirements

PowerStore requires connectivity to a pair of Top-of-Rack (ToR) switches.

This section describes the requirements for:

● Switch to switch (L2) connectivity

● Node to ToR switch connectivity

Top-of-Rack (ToR) switch to ToR switch (L2) connectivity options

Use one of the following options to connect the two ToR switches together.

Table 4. ToR switch to ToR switch interconnect options

Switch interconnect

options

Recommendation

1. Multi-chassis Link

Aggregation Group (MC-LAG)

Dell highly recommends using MC-LAG for connectivity between the switches.

2. L2 Uplinks without MC-LAG If MC-LAG is not an option, then the next best recommended connectivity between the

switches is to use reliable L2 uplinks.

NOTE: If neither of the switch interconnect options are available then you can use a Direct Trunk Link, but this is not

recommended.

Multi-chassis Link Aggregation Group (MC-LAG) interconnect

It is highly recommended that you deploy PowerStore with an MC-LAG interconnect between the two ToR switches.

In an MC-LAG environment, the two switches are treated as one logical switch. This allows you to add all the uplinks from both

switches into a single port channel that will span the MC-LAG.

NOTE: Port location for the reliable high speed uplinks may change depending on switch vendor or model.

MC-LAG is a switch interconnection technology that joins a number of independent Top-of-Rack (ToR) switches into a single

virtual chassis. MC-LAG allows the link aggregation (LAG) port groups to span multiple chassis, enabling better resilience of

the LAG connection. Additionally, MC-LAG enables traffic going from switch to switch using the full bandwidth of the available

connection, without using spanning tree protocol (STP), which would disable some links to prevent loops.

MC-LAG is a general name for the technology, however certain vendors use their own proprietary terminology to define

MC-LAG connectivity.

Table 5. Vendor specific MC-LAG technology

Vendor Proprietary MC-LAG technology

Dell Virtual Link Trunking (VLT)

Cisco Virtual PortChannel (vPC)

Brocade Multi-Chassis Trunking (MCT)

NOTE: Refer to your vendor's documentation to determine their technology for MC-LAG.

MC-LAG connectivity requirements are:

● A minimum of two connection cables in parallel with a high speed reliable connection.

● Connections must be made through the high speed ports on the switch. Verify with your switch provider documentation

where the high speed ports are located on your switch.

● Use two cables that support connectivity between the high speed ports. For example 100Gbps Direct Attached Cables

(DAC) would be required to connect the MC-LAG ports together.

L2 Uplinks without MC-LAG

Using L2 (Ethernet level) uplinks without an MC-LAG connection to connect the ToR switches is an acceptable alternative to

MC-LAG for PowerStore deployments.

With a non-MC-LAG L2 connection you can port-channel the uplinks on each physical switch, which requires creating two

port-channels instead of one.

NOTE: Port location for the reliable high speed uplinks may change depending on switch vendor or model.

Non-MC-LAG L2 connectivity requires redundant, high speed connections.

Node to Top-of-Rack (ToR) switch connectivity

Deploying with Top-of-Rack (ToR) switches requires that each of the base enclosure appliance nodes have at least one

connection to each of the ToR switches to provide redundancy at the NIC and switch levels.

Figure 3. Node to ToR switch cabling

When cabling the nodes to the switches:

● Port 0 and Port 1 on the same node must connect to opposite switches

● Port 0 on Node A, and Port 0 on Node B must connect to opposite switches

● Port 1 on Node A, and Port 1 on Node B must connect to opposite switches

18

PowerStore X model: Network configuration requirements

PowerStore X model networks

PowerStore X model requires all networks to be unique. It is highly recommended to deploy PowerStore X model with multiple

and unique VLANs to separate the traffic. However, if only one VLAN is available, you have the option to deploy PowerStore X

model with a single VLAN and multiple unique subnets as demonstrated below.

Figure 4. PowerStore X model network traffic

Ensure that the PowerStore X model interfaces are able to communicate to each other through the VLANs shown above.

Consult your network vendor documents to ensure all proper L2 and/or L3 traffic is being routed properly for all networks that

PowerStore X model is utilizing.
