What describes Dell PowerStore X front-end cabling?

Full set: 95 questions

Domain PowerStore Initial Configuration and Administration

Answer options
A: Uses internal VMware virtual switching and does not require a management network
B: Storage and management use the same LACP bonded cable connection
C: Uses VLTi data switch interconnectivity to support vMotion networks
D: Management and discovery use the same cables and connections as storage Correct answer
Correct Answer:
D. Management and discovery use the same cables and connections as storage
Explanation

In a Dell PowerStore X model, the architecture is hyperconverged, running the PowerStoreOS within a virtual machine on a VMware ESXi hypervisor. This design utilizes a converged network approach for front-end connectivity. The same physical 25/10 GbE ports on the embedded module are used for multiple traffic types, including system management, initial discovery, storage traffic (iSCSI), and vSphere traffic such as vMotion. These traffic types are segregated logically using VLANs and virtual switches within ESXi, but they all traverse the same physical cables and switch connections.

Why Incorrect

A. PowerStore X requires a management network for initial discovery, configuration, and ongoing administration. While it uses internal VMware virtual switching, the management network is mandatory.
B. While Link Aggregation Control Protocol (LACP) can be configured on the network switches and vSphere Distributed Switch, it is not the default or required configuration. The fundamental concept is shared physical connectivity, not a specific bonding protocol.
C. Virtual Link Trunking interconnect (VLTi) is a feature of Dell network switches used to create a high-availability, loop-free network fabric. It is a recommended network design but describes the switch infrastructure, not the PowerStore appliance's cabling.

Reference: Page 11, Section "Network considerations for PowerStore X models".

Quote/Content: "For PowerStore X models, the management, storage, and vMotion networks are configured on the embedded module 25/10 GbE ports 0 and 1. These ports are used for system management, iSCSI storage traffic, and vSphere activities such as vMotion." This directly supports that management and storage use the same connections.

Reference: Page 16, Section "PowerStore X model appliances".

Quote/Content: "The PowerStore X model leverages the same hardware platform as the PowerStore T model, but it runs the PowerStore OS in a virtual machine (VM) on a VMware ESXi hypervisor... This allows the appliance to support both native PowerStore block and file services, and VMware vSphere virtualized workloads on the same appliance." This architectural description implies the need for shared front-end networking for both storage and hypervisor management.
