The correct procedure for a Storage Administrator to add a new PowerStore 9000T appliance into an existing single appliance Dell EMC PowerStore 3000T cluster is toadd the new 9000T appliance into the cluster per the procedure; mixed models of the same type are supported.

Dell PowerStore allows for the addition of appliances to an existing cluster, enabling both scaling up and scaling out.

When adding a new appliance to an existing cluster, it is important to ensure that the appliance is uninitialized and that both the new appliance and the existing cluster are in a healthy state1.

The process of adding an appliance is facilitated through the PowerStore Manager.The administrator should navigate to theHardwarepage and click theAddbutton to present the available unconfigured appliances that can be added1.

It is not necessary to configure additional VLT links on the ToR switching specifically for the 9000T to support the increased inter-switch network load as part of the initial addition process1.

There is no requirement that the appliance model and type must match when clustering appliances together, allowing for mixed models of the same type within a cluster1.

Removing NVMe NVRAM drives from the 9000T is not a standard procedure for clustering and is not required for the caching configuration of all clustered appliances to match1.

For detailed procedures on adding appliances to a Dell EMC PowerStore cluster, it is recommended to refer to the official Dell PowerStore Clustering and High Availability documentation or contact Dell EMC support for guidance.

The Dell EMC PowerStore base enclosure contains two nodes.These nodes are configured in an Active-Standby mode to ensure high availability and load balancing1. Each node is 1U in size and stacks vertically within the base enclosure, with the top node inverted to fit within the compact design.This configuration allows for one node to be actively handling workloads while the other stands by ready to take over in case of a failure or maintenance event, ensuring continuous operation and data accessibility1.

For more detailed information on the node configuration within the PowerStore base enclosure, administrators can refer to the Dell PowerStore Introduction to the Platform documentation, which provides insights into the system’s architecture and design considerations1. It is important to understand the node roles and configurations to effectively manage and maintain the PowerStore system.

A Dell EMC PowerStore node can tolerate one fan module failure.The system is designed with redundancy to ensure that if a single fan module fails, the remaining fan modules can compensate for the loss and maintain proper cooling to prevent overheating1. The system will increase the speed of the remaining fans to ensure continued cooling.

When a fan module failure occurs, the system will generate an alert to notify the administrator of the fault. The administrator should then take the following steps:

Acknowledge the alert in the PowerStore Manager.

Plan for the replacement of the faulted fan module as soon as possible to restore full redundancy.

Follow the replacement procedures as outlined in the Dell PowerStore Installation and Service Guide1.

It is important to address fan module failures promptly to ensure the long-term health and performance of the PowerStore system. The increased fan speed is a temporary measure to maintain operations until the faulted fan module can be replaced.

When planning for a Dell EMC PowerStore T implementation, the minimum number of IP addresses required for the storage network is two. This is because each PowerStore T appliance requires a minimum of one IP address per node for the storage network.Since the PowerStore T model typically comes with two nodes (Node A and Node B), you will need at least two IP addresses—one for each node1.

It’s important to note that while two IP addresses are the minimum requirement, having additional IP addresses can be beneficial for optimization purposes.For example, the PowerStore 3000X, 5000X, 7000X, and 9000X models recommend having six IP addresses minimum per appliance for the storage network, with eight being recommended for optimization2.

In summary, for a basic PowerStore T setup, two IP addresses are required for the storage network to accommodate each node within the appliance. However, depending on the specific model and the scale of your implementation, more IP addresses may be recommended to ensure optimal performance and management of the storage network.
