os10-disk-1.0.0.vmdk typically refers to the virtual disk image for Dell EMC Networking OS10

, often used for running the switch operating system within virtualized lab environments like VMware ESXi

To "put together a post" about this, here is a structured guide you can use for a technical blog or internal documentation: Dell OS10 Virtual Lab Setup Guide 1. Overview

Dell EMC Networking OS10 is a Linux-based open networking operating system. The

file is the virtual disk used to boot the OS in a Virtual Machine (VM). This setup is ideal for testing configurations, automation scripts (Ansible/Python), or learning the OS10 CLI without physical hardware. 2. Prerequisites os10-disk-1.0.0.vmdk Hypervisor: VMware Workstation, ESXi, or a lab simulator like Resources (Minimum): 1 Management Interface + multiple data interfaces. 3. Deployment Steps Create the VM Shell: Create a new "Other Linux 64-bit" VM. Attach the Disk: Replace the default new hard disk with your existing os10-disk-1.0.0.vmdk In ESXi, you can use the Add Second Virtual Disk

method to ensure the disk is correctly mapped to the SCSI controller. Configure Network Adapters:

Ensure the first adapter (Network Adapter 1) is mapped to your Management network. Subsequent adapters act as front-panel switch ports. Initial Boot:

Power on the VM. It will take several minutes to initialize the database and services. 4. Initial Configuration Access the CLI via the console connection to perform the first setup: Default Credentials: Command to enter configuration mode: configure terminal Set Management IP: interface mgmt no ip address dhcp ip address no shutdown Use code with caution.

Always take a snapshot immediately after the first successful login. OS10 can be sensitive to "dirty" shutdowns.

Some OS10 images boot into ONIE (Open Network Install Environment) first. Ensure you select the "OS10 Install" or "OS10" boot option if prompted. technical forum

The file os10-disk-1.0.0.vmdk is a primary virtual disk component used to deploy the Dell EMC SmartFabric OS10 switch operating system in virtual lab environments like EVE-NG, GNS3, or VMware. It acts as the base storage drive where the OS installer places the system files during the initial boot process. Guide: Setting Up Dell OS10 in Your Virtual Lab

This guide explains how to use the os10-disk-1.0.0.vmdk file to build a sandbox for testing open networking concepts. 1. Prepare Your Image Files

To create a working node, you typically need three specific files extracted from the Dell virtualization ZIP archive: OS10-Disk-1.0.0.vmdk (The base disk) OS10-Installer-VERSION.vmdk (The installation media)

OS10-platform-S6010-VERSION.vmdk (The platform-specific disk) 2. Import into EVE-NG

If you are using EVE-NG, follow these steps to convert the files for QEMU:

Create Directory: mkdir /opt/unetlab/addons/qemu/dellos10-YOUR_VERSION

Upload Files: Use WinSCP or FileZilla to move all three .vmdk files into that folder.

Convert to QCOW2: Run these commands inside the folder to make them compatible with the hypervisor:

qemu-img convert -f vmdk -O qcow2 OS10-Disk-1.0.0.vmdk sataa.qcow2

qemu-img convert -f vmdk -O qcow2 OS10-Installer-VERSION.vmdk virtiob.qcow2

qemu-img convert -f vmdk -O qcow2 OS10-platform-VERSION.vmdk virtioc.qcow2 Clean Up: Delete the original .vmdk files to save space.

Fix Permissions: Run /opt/unetlab/wrappers/unl_wrapper -a fixpermissions. 3. First Boot & Credentials

When you add the node to a lab and power it on for the first time, it will automatically install the OS onto the sataa.qcow2 disk. 💡 Key Credentials: Default Username: admin Default Password: admin Linux Shell Account: linuxadmin (Password: linuxadmin) Resources for Advanced Setup Dell OS 10 - - EVE-NG

The file os10-disk-1.0.0.vmdk is a critical component for running Dell EMC SmartFabric OS10 in a virtualized environment. It acts as the base virtual disk image, allowing network engineers to simulate high-end Dell switches on their laptops for testing and labbing. 🛠️ What is it used for?

This specific .vmdk file is typically part of a three-file set required to boot a Dell OS10 virtual appliance: os10-disk-1.0.0.vmdk: The system disk image.

OS10-Installer-xxx.vmdk: The installation image containing the OS.

OS10-platform-xxx.vmdk: Defines the hardware personality (e.g., S6010 or S5248F). 🚀 How to set it up (The "Interesting" Way)

While you can run this in VMware, most pros use it in network simulation tools like GNS3 or EVE-NG to build massive virtual data centers. 1. The EVE-NG "Conversion" Trick

EVE-NG doesn't use .vmdk files directly; it prefers the more efficient .qcow2 format. You’ll need to convert it using the QEMU command-line tool:

# Convert the disk to qcow2 format qemu-img convert -f vmdk -O qcow2 os10-disk-1.0.0.vmdk sataa.qcow2 Use code with caution. Copied to clipboard

Tip: Rename the output to sataa.qcow2 so the emulator recognizes it as a SATA drive. 2. Importing into GNS3

If you prefer GNS3, you can use the Dell OS10 Appliance template. Drag the OS10 node onto your workspace.

When prompted, upload os10-disk-1.0.0.vmdk alongside the Installer and Platform files.

Pro Move: Set your console type to VNC initially to watch the ONIE (Open Network Install Environment) boot process—it's like watching a switch being born in real-time. 💡 Pro Tips for your Lab

Snapshots are your friend: Before you start making complex configuration changes, take a snapshot in your hypervisor. If you break the routing table, you can revert in seconds.

Resource Management: Dell OS10 is "heavy." Ensure your host has at least 4GB of RAM and 2 vCPUs dedicated just to this one virtual switch.

ONIE Boot: On the first boot, the system will look for an installer. Make sure your OS10-Installer vmdk is also connected, or it will sit in a "discovery" loop forever.

Part 10: Real-World Use Case – Virtual Network Lab

Imagine you are a network engineer testing BGP EVPN. You have os10-disk-1.0.0.vmdk as the base image for four virtual switches.

1. Clone the VMDK four times using vmkfstools -i (linked clones to save space).
2. Attach each to a separate VM with 2 vCPUs, 4GB RAM.
3. Connect via a virtual distributed switch (VDS) with VLAN trunking.
4. Configure OS10’s RESTCONF API or CLI over SSH.

The version string 1.0.0 ensures all switches run identical firmware, eliminating version-related routing bugs.

Note:

You’ll likely need the accompanying .vmx (VM configuration file) or create a new VM and attach this .vmdk as an existing disk.

The file "os10-disk-1.0.0.vmdk" appears to be a virtual disk image file, specifically in the VMDK (Virtual Machine Disk) format. This format is commonly used with VMware virtualization software.

Part 1: Decoding the Nomenclature

Before diving into technical details, let’s break down the filename os10-disk-1.0.0.vmdk:

| Component | Meaning | |-----------|---------| | os10 | Typically refers to Operating System 10. In many networking contexts, this points to DNOS10 (Dell Networking Operating System 10) or a similar network OS. It could also denote a generic "OS version 10" from a custom appliance. | | disk | Indicates this is the primary virtual hard disk (as opposed to a floppy, CD-ROM, or NVRAM file). | | 1.0.0 | A semantic version number (Major.Minor.Patch). This suggests the disk image is tied to release 1.0.0 of the OS. | | .vmdk | Virtual Machine Disk – VMware’s proprietary (but open-spec) format for virtual hard drives. |

Key Insight: If you find this file in a production environment, it likely belongs to a virtualized network switch (like Dell S-Series or N-Series) or a specialist embedded OS appliance, not a standard Windows or Linux desktop.
