For 6 DAEs, the maximum number of supported 2.5 inch drives is 250 disks. For 20 DAEs, the maximum number of supported 2.5 inch drives is 1000 disks. For 10 DAEs, the maximum number of supported 2.5 inch drives is 150 disks. Review the Dell Unity System Specifications: The Dell Unity system’s Drive Array Enclosures (DAEs) have different capacities, which determine the number of drives they can support1. Match DAE Capacity to Drive Support: Each DAE capacity has a corresponding maximum number of supported drives, as outlined in the Dell VxBlock Deploy Achievement document1. Verify with Official Documentation: Cross-reference the information with the official Dell documentation to ensure the accuracy of the drive support for each DAE capacity1.

 VxBlock Central  Network  Storage  Compute  Virtualization In the Dell EMC RCM (Release Certification Matrix) Workbook upgrade plan, the sequence of upgrading VxBlock components is designed to ensure system stability and minimize disruptions. Here’s the detailed reasoning for the correct sequence: VxBlock Central: Explanation: VxBlock Central is the management and orchestration layer of the VxBlock system. Upgrading this first ensures that the management tools are compatible with the new versions of the other components and can properly coordinate and monitor the upgrade process. Reference: Dell EMC documentation emphasizes upgrading management and orchestration tools first to ensure compatibility and support for subsequent upgrades. Network: Explanation: The network forms the backbone of the VxBlock system, connecting all components. Upgrading the network components ensures that any changes or enhancements in connectivity, bandwidth, or protocols are in place before upgrading the other components that rely on network connectivity. Reference: Best practices in infrastructure upgrades recommend updating network components early to ensure they can support new features and functionalities of other upgraded systems. Storage: Explanation: Upgrading storage components next ensures that the data layer is optimized and capable of handling new features and improvements. It also ensures data integrity and performance enhancements are in place before upgrading compute and virtualization layers. Reference: Dell EMC guidelines for VxBlock upgrades often prioritize storage upgrades after network to secure the data layer. Compute: Explanation: Compute resources (servers and processing units) are upgraded next to ensure they are compatible with the updated storage and network components. This prepares the infrastructure for any new workloads or virtualization enhancements. Reference: The compute upgrade follows storage to ensure that the processing power can efficiently utilize the enhanced storage capabilities. Virtualization: Explanation: Finally, the virtualization layer (such as VMware vSphere) is upgraded. This layer is highly dependent on the underlying hardware and network infrastructure. Ensuring all underlying components are upgraded and stable first guarantees that the virtualization environment can fully leverage the improvements and new features. Reference: Virtualization upgrades are typically performed last to ensure full compatibility with all previously upgraded components and to minimize the risk of disruptions. Following this sequence ensures a structured and stable upgrade process, aligning with Dell EMC’s recommended practices for maintaining system integrity and performance during upgrades.

Based on the Dell VxBlock Deploy Achievement document, the roles and their responsibilities are matched as follows: Implementation Specialist: Connect system to power and network1. Architect: Create the logical configuration survey1. Customer Engineer: Deliver the remote knowledge transfer1. Project Manager: Plan and coordinate engagement related activities1. Implementation Specialist: This role is typically responsible for the physical aspects of the deployment, such as connecting the system to power sources and the network1. Architect: The Architect’s responsibility includes designing and creating surveys that capture the logical configuration of the system1. Customer Engineer: This role often involves interfacing with the customer and providing knowledge transfer to ensure they understand the system1. Project Manager: The Project Manager oversees the project, planning, and coordinating all activities related to the engagement1.

When planning a compute expansion in an existing VxBlock 1000 system with servers repurposed

from another VxBlock system, the required licensing includes VMware vSphere ESXi and Cisco 1000v

licenses. These licenses ensure that the new compute resources are properly integrated and

managed within the existing VxBlock environment.

Understand VxLAN: VxLAN, or Virtual Extensible LAN, is a network virtualization technology that

allows for the creation of a Layer 2 network on top of a Layer 3 network1.

Identify Key Benefit: One of the key benefits of VxLAN is that it enables vMotion to occur over Layer 3

subnets, which can span across different geographic locations1.

Recognize VxLAN Capabilities: By encapsulating Layer 2 Ethernet frames into Layer 4 UDP packets,

VxLAN allows for the extension of networks over long distances, facilitating vMotion in environments

where the physical network infrastructure is spread out1.

Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would

align with this understanding of VxLAN, highlighting its ability to support vMotion across Layer 3

subnets as a significant advantage1.
