When planning for a Dell PowerStore T implementation, how many IP addresses are required for the storage network?

For a standard Dell PowerStore T model implementation, the storage network requires a minimum of two IP addresses. A PowerStore T appliance is built on a dual-node architecture for high availability. For iSCSI host connectivity, each of the two nodes requires its own dedicated IP address on the storage network. This configuration allows for redundant paths and load balancing, ensuring continuous data access if one node or path becomes unavailable.

B. 1: A single IP address would introduce a single point of failure, which contradicts the high-availability design principles of the PowerStore T architecture.

C. 3: This is the number of IP addresses required for the management network (one cluster management IP and one for each of the two nodes), not the storage network.

D. 4: While four or more IPs could be used by configuring multiple storage network ports on each node, the fundamental requirement for a basic, resilient implementation is two.

1. Dell PowerStore: Networking Guide for PowerStore T Models (June 2023). In the "Network IP address planning" section, the table titled "PowerStore T model appliances" explicitly states for the "Storage network": "Two IP addresses are required for the storage network. These IP addresses are used for iSCSI host connectivity." (Page 13).

2. Dell PowerStore: Planning Guide (April 2023). The "Network considerations" chapter contains a table, "IP address requirements for a PowerStore T model appliance," which specifies a quantity of "2" for the "Storage network," with the description "One per node for iSCSI traffic." (Page 23).
