Dell PowerStore PowerStore T and Q Networking Guide for Storage Services

Get the completed Switch resources for Storage services worksheet

Before configuring PowerStore T model, you should have worked with your network administrator to reserve network resources, and complete the Switch resources for Storage services worksheet.

The following Switch resources for Storage services worksheet has been completed with the network resources that are used in the configuration steps that are provided in this document. You can use this worksheet exactly as it is when deploying your PowerStore T model networks with Dell PowerSwitches Series S4148 switches.

If you are not configuring your switches and networks with the resources that are used in this guide, you can complete a new Switch resources for Storage services worksheet with the information relevant to your environment. To download a blank worksheet, see Switch resources for Storage services worksheet (blank).

Table 1. Switch resources for Storage services worksheet (completed)The entries in this worksheet provide the information that is used to configure the switches for the sample configuration provided in this guide.
Step Details Notes
1. Print this table to record the reserved resources.
2 Reserve and record the IP addresses necessary to configure the ToR switches below:
Management IP address for ToR Switch 1 100.0.100.10/24
Management IP address for ToR Switch 2 100.0.100.11/24
Default gateway 100.0.100.1
NTP server 100.0.100.200
3. 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.

Spanning tree protocol for ToR Switch 1 40960
Spanning tree protocol for ToR Switch 2 45056
4.

Choose which Layer 2 interconnect to configure between the switches:

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

Continue to step 5.

Yes
Direct Interconnect not using MC-LAG

Continue to step 6.

N/A
No direct interconnect between the switches

Continue to step 6.

N/A
5. If you are using MC-LAG, record the ports to use to connect the switches together.

ToR Switch 1 to ToR Switch 2-port pair 1

25 to 25
ToR Switch 1 to ToR Switch 2-port pair 2 26 to 26
Enter the port channel ID used for connectivity between the ToR switches and the uplinks.

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

port channel 50
If using MC-LAG, enter the Domain ID. VLT domain ID 1
If using uplinks for Layer 2 connectivity between the switches, continue to step 6. N/A
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.
00:00:00:00:00:01
VLT priority for ToR Switch 1 1
VLT priority for ToR Switch 2 8192
MTU setting for Jumbo Frames
NOTE:It is recommended to configure jumbo frames with an MTU setting of 9216. The same MTU size must be set on both switches for both node ports.
9216
6. If configuring the ToR switches with a direct Interconnect not using MC-LAG, or without a direct connection between the ToR switches, record the ports on the ToR switches to use to connect to the uplinks.
Uplink A to ToR Switch 1 port 29
Uplink B to ToR Switch 1 port 30
Uplink A to ToR Switch 2 port 29
Uplink B to ToR Switch 2 port 30
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 N/A
2. Port channel ID for L2 Uplinks without MC-LAG N/A
7. Reserve the network resources required to configure the networks and the ports to connect from the PowerStore appliance nodes to the Top-of-Rack (ToR) switch ports for each Storage network to configure.

You can put multiple storage networks on the same ports, or you can connect each storage network through different ports.

When cabling from the node ports to the ToR switch ports, the corresponding ports on Node A and Node B should connect to opposite switches.

NOTE:Ports 0 and 1 of the 4-port card are reserved for the cluster network with all PowerStore appliances. If deploying a PowerStore 500T appliance, ports 2 and 3 of the 4-port card are reserved for connectivity to the 24 Drive 2.5-Inch NVMe (ENS24) expansion enclosures.

Network Attached Storage (NAS) must be configured in an LACP bond.

It is recommended that you configure the bond with one port from different I/O modules.

When configuring an LACP bond:

  • The PowerStore appliance node ports that are cabled for LACP must be the same speed.
  • LACP can be configured using two or four ports on each node, however the same number of ports must be configured for LACP on both nodes.
