The Converged Systems Administration Guide includes a complete list of tools used to perform a

VxBlock 1000 upgrade. This guide provides detailed instructions and necessary resources for

administrators to manage and upgrade VxBlock systems.

Best practices for system upgrades and administration.

The data layout technique used on an Isilon cluster is Forward Correction Error (FEC). This method

ensures data integrity and availability by distributing error correction information across the nodes in

the cluster, allowing for data recovery in the event of hardware failures.

When creating an NSX logical switch, a required step is to create a new name for the logical switch.

Naming the logical switch is necessary to identify and manage it within the NSX environment.

VMware NSX documentation on creating logical switches.

Best practices for network virtualization.

In the RCM (Release Certification Matrix) Upgrade Process RACI (Responsible, Accountable,

Consulted, Informed) matrix, the pre-upgrade questionnaire used during the Initiation Phase is

typically the responsibility and accountability of the Project Manager and the Customer. The Project

Manager ensures the completion of the questionnaire to gather necessary information for planning

the upgrade, while the Customer provides the required data.

Standard RACI matrix practices in project management.

Review the VxBlock and Nexus Documentation: The VxBlock 1000 system documentation and the

Nexus 93180YC switch documentation should be reviewed to understand the supported routing

protocols1.

Consider the Juniper Switch Capabilities: Since the customer is using a Juniper switch as the core

switch, it’s important to consider the routing protocols supported by Juniper switches. Juniper

switches support a variety of routing protocols, including OSPF2.

Evaluate Routing Protocol Options: EIGRP is typically Cisco proprietary and not supported on Juniper

devices. IGMP is not a routing protocol but a multicast management protocol. IGRP is an older Cisco

proprietary routing protocol and is less commonly used today2.

Recommend OSPF: OSPF (Open Shortest Path First) is a widely supported, robust, and scalable

dynamic routing protocol that is suitable for diverse environments, including mixed vendor setups

like Cisco’s Nexus and Juniper switches2.

Validate with Best Practices: Best practices and recommendations from both Cisco and Juniper

suggest using OSPF for dynamic routing between devices from different vendors2.

Locate the validation procedures and support documentation: The Implementation Specialist must

locate the necessary validation procedures and support documentation that are essential for the

deployment of the VxBlock Systems1.

Connect the VxBlock System to the customer network: After locating the documentation, the

specialist is responsible for connecting the VxBlock System to the customer’s network1.

Validate a VxBlock 1000 installation using the LCS and Test Plan: The specialist must validate the

VxBlock 1000 installation using the Lifecycle System (LCS) and the Test Plan to ensure that the system

is correctly implemented and functioning as intended1.

Describe how to perform knowledge transfers: Part of the specialist’s role is to describe the process

of knowledge transfer, ensuring that the customer’s staff is adequately trained and informed about

the system1.

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.

VMware licensing documentation.

Cisco licensing guides for UCS and network components.

Review Project Closure Documents: The project closure phase involves several key documents that

need to be reviewed and signed off to formally close the project1.

Identify Required Document: In addition to the Final Test Plan and Customer Satisfaction Survey, the

Final Project Signoff is a crucial document that must be signed by the customer at the Project Closure

Meeting1.

Understand the Significance: The Final Project Signoff serves as the customer’s formal acceptance of

the project deliverables and confirms that all contractual obligations have been met1.

Ensure Compliance: It is important to ensure that the Final Project Signoff is completed and signed

by the customer to officially close the project and release the project team from further

responsibilities1.

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.

Match each team member with their RACI role as follows: Project Manager: Primary point of contact; manages overall project and communications Assessment Team Lead: Ensures proper assessment execution and validates upgrade sequence plan Assessment Team: Communicates upgrade progress and issues to the PM Delivery Manager: Transitions requirements and upgrade plan to the upgrade team Upgrade Team: Point of contact for internal escalations Project Manager: Primary point of contact; manages overall project and communications The Project Manager is responsible for overseeing the entire project, coordinating all activities, and serving as the main point of contact for stakeholders. Assessment Team Lead: Ensures proper assessment execution and validates upgrade sequence plan The Assessment Team Lead oversees the assessment phase, ensuring that the evaluation is thorough and that the upgrade sequence is properly planned and validated. Assessment Team: Communicates upgrade progress and issues to the PM The Assessment Team members are responsible for executing the assessment tasks and reporting progress and any issues encountered to the Project Manager. Delivery Manager: Transitions requirements and upgrade plan to the upgrade team The Delivery Manager is responsible for ensuring that all requirements and the upgrade plan are effectively communicated and handed over to the upgrade team for execution. Upgrade Team: Point of contact for internal escalations The Upgrade Team handles the actual upgrade process and serves as the primary point of contact for any internal escalations that may arise during the upgrade.
