• PowerStore Hardware Information Guide PowerStore deployment models The different PowerStore models support different types of storage. Table 2. PowerStore deployment models Deployment Model numbers Supported configuration Refer to PowerStore T model appliance • • • • • 1000T 3000T 5000T 7000T 9000T Supports block (Storage Area Network (SAN)), file (Network Attached Storage (NAS)), and Virtual Volume (vVol) workloads with the software stack deployed directly on the bare metal of the system.
NOTE: The examples used in this guide describe how to cable port 0 and port 1 of the 4 port card on the base enclosure nodes. See the PowerStore Clustering and High Availability White Paper for specific steps to add more ports to provide additional bandwidth and fault tolerance. Top-of-Rack (ToR) switches PowerStore requires connectivity to a pair of Top-of-Rack (ToR) switches to ensure high availability.

Switch to switch (L2) connectivity options It is recommended to use one of the following options to connect the switches together. Table 4. Switch to 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. Reliable L2 uplinks If MC-LAG is not an option, then the next best recommended connectivity between the switches is to use reliable L2 uplinks.
Table 5. Vendor specific MC-LAG technology(continued) Vendor Proprietary MC-LAG technology 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.
Node to Top-of-Rack (ToR) switch connectivity requirements A dual switch topology requires that each of the base enclosure appliance nodes have at least one connection to each of the Top-of-Rack (ToR) switches to provide redundancy at the NIC and switch levels. Figure 13.

Topics: • • • PowerStore T model appliance networks PowerStore T model network VLAN requirements IP address requirements for initial configuration PowerStore T model appliance networks PowerStore T model requires all networks to be unique. It is highly recommended to deploy PowerStore T model with multiple and unique VLANs to separate the traffic.
Ensure that the PowerStore T model system 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 T model is utilizing. Table 6.
PowerStore T model network VLAN requirements The following table shows an example of the different type of networks with sample VLAN IDs in a PowerStore T model appliance. Table 7. PowerStore T model VLAN configuration Sample VLAN ID Network Switch used VLAN Ports Subnet 100 Remote Discovery (runs over the Native VLAN) Out-of-band management Untagged 169.254.x.x/16 100 Management Out-of-band management Untagged y.y.y.y/24 200 Storage Top-of-rack (ToR) switch Tagged y.y.x.
Table 8. PowerStore T model IP address requirements(continued) Network IP Addresses Required Grand total required per Appliance for Management and Storage 5 Grand total for a Single Appliance Cluster 7 You can choose to assign either IPv4 or IPv6 addresses to the management, or storage networks. You cannot assign different IP versions to the same network, for example, all 4 IPs assigned to the management network must all be either IPv4 or IPv6.
