The correct description of the SAS cabling when adding an expansion enclosure to a Dell EMC
PowerStore, for each node and expansion enclosure side, is Option D: SAS cabling goes from existing
A ports to new B ports. At the last enclosure, SAS cabling returns from the A ports to the alternate
node’s B ports.
When adding a SAS expansion enclosure to a Dell EMC PowerStore system, the cabling must be done
in a specific manner to ensure proper connectivity and performance.
The SAS cabling should start from the existing A ports on the base enclosure and connect to the new
B ports on the expansion enclosure1
.
At the last expansion enclosure in the chain, the SAS cabling should return from the A ports back to
the B ports on the alternate node1
.
This cabling method ensures that each node is connected to each expansion enclosure and that the
enclosures are daisy-chained correctly for optimal performance and redundancy1

Explanation:
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 to add 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 the Hardware page and click the Add button 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.

External hosts connect to the Dell EMC PowerStore cluster for data access through the Storage
network.
The Storage network is designed to handle the data traffic between the PowerStore system and the
external hosts.
For optimal performance and availability, it is recommended to configure dual redundant fabrics in
Fibre Channel configurations, ensuring that each PowerStore node and each external host have
connectivity on each of the fabrics12
.
This setup minimizes the number of hops between the host and PowerStore, which is crucial for
maintaining high-speed data access and reducing latency12
.
The Management network, on the other hand, is used for managing and configuring the PowerStore
system, not for data access3
.
The Service network is typically used for service tasks and is not intended for regular data access by
external hosts3
.
The Internal network is used for communication within the PowerStore cluster itself and is not
accessible by external hosts.

Explanation:
For intra-cluster management within Dell EMC PowerStore systems, the internal network is used.
This network is specifically named the Intra-Cluster Management (ICM) and Intra-Cluster Data (ICD)
networks.
Each node in a PowerStore cluster communicates with other nodes through bonded ports
that are part of this internal network12
.
The ICM and ICD networks are crucial for the cluster’s operation as they allow for the management
and coordination of data across the cluster. In multi-appliance PowerStore clusters, these networks
communicate through the top-of-rack switch network with untagged VLAN network packets that
have auto-generated IPv6 addresses.
For single-appliance clusters, starting in PowerStoreOS 1.0.2,
the ICM network communicates through the backplane within the appliance instead of through the
top-of-rack switch2
.
In summary, the internal network is essential for the functioning of a PowerStore cluster as it
facilitates the necessary communication between nodes for management and data operations. This
design ensures high availability and efficient management of the storage system.

In Dell EMC PowerStore Manager, a defective embedded module is displayed as orange with a
faulted state. This color coding is used to indicate that there is a fault with the embedded module.
The PowerStore Manager provides a visual representation of the system’s health and status, and the
color orange is typically associated with a warning or an issue that needs attention.
The procedure for identifying and replacing a faulted embedded module involves using the
PowerStore Manager to locate the faulted component. Once identified, the module displays an
orange LED to indicate its faulted state.
This is part of the system’s design to help administrators
quickly and easily identify components that require attention1
.
For detailed instructions on replacing a faulted embedded module or understanding the LED states
for troubleshooting, you can refer to the PowerStore documentation provided by Dell, which

Explanation:
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.
