Integrating NSX for virtual networking while retaining ACI for physical networking is possible, but it may be cost prohibitive. This approach requires careful planning and management of both virtual and physical network environments, potentially leading to higher operational costs and complexity.

Review XtremIO X2 Specifications: The XtremIO X2 storage array is designed to support a scale-out architecture, allowing for the addition of multiple X-Bricks to increase capacity and performance1.

Identify Maximum X-Bricks: According to the specifications, a single XtremIO X2 array can be scaled out to a maximum of 8 X-Bricks1.

Understand Capacity Expansion: This scale-out capability enables the XtremIO X2 array to reach a large physical capacity, accommodating the storage needs of various applications and workloads1.

Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would align with this information, providing details on the scalability options for the XtremIO X2 storage array1.

Review the RCM Assessment Workbook: The RCM (Release Certification Matrix) Assessment Workbook is a tool used during the upgrade process of VxBlock systems1.

Understand the Workbook's Purpose: Its primary use is to identify items and components within the VxBlock system that require remediation before an upgrade can be performed1.

Utilize the Workbook: By using the RCM Assessment Workbook, engineers can systematically review the current state of the system and pinpoint areas that need attention1.

Ensure Compliance: This step is crucial to ensure that all components meet the necessary standards and are compatible with the new RCM version1.

The Distributed Logical Router (DLR) is the NSX component that abstracts the physical network and provides access-level switching in the hypervisor. The DLR enables routing between different virtual networks and operates at the hypervisor level, providing high-performance distributed routing capabilities.

In a VxBlock 1000 system running VMware vSphere 6.7, the Fabric Interconnect should be mapped to the access switch in a traditional data center architecture. The Fabric Interconnect is responsible for aggregating traffic from the servers before it is sent to the upstream network, functioning similarly to an access switch which connects end devices to the broader network infrastructure.
