vSphere Networking : Virtual Switch VLAN

VLANs intro
 VLANs (Virtual LANs) are logical groupings of devices in the same broadcast domain.  They are usually configured on switches by placing some ports into one broadcast domain and other ports into another. VLANs can spread across multiple switches, enabling communications as if all virtual machines or ports in a VLAN are on the same physical LAN segment. Here in networkRead More…

Connect ESXI to NFS storage Part I :Introduction

NAS vs NFS
before diving inside , we have to  differentiate between NAS and NFS. NAS is a type of network design. NFS is a type of Protocol used to connect to a NAS. Network Attached Storage (NAS) is a device that allows users to access files through a network. It allows users to access and share files from their individual stations through a central server.  NFS (Network File SystemRead More…

Connect ESXI to ISCSI storage Part I :Introduction

ISCSI introduction
ISCSI stand for Internet Small Computer System Interface   iSCSI is an industry standard protocol which allows sharing of block storage over Ethernet. It is a protocol for communicating with I/O devices, chiefly storage devices. iSCSI is an IP-based standard for connecting data storage devices over a network and moving data by carrying SCSI commands over IP netwRead More…

ESXI Storage introduction Part II

What is a datastore?
DataStores in VMware vSphere are storage containers for files. They could be located on a local server hard drive or across the network on a SAN.  DataStores hide the specifics of each storage device and provide a uniform model for storing virtual machine files. DataStores are used to hold: virtual machine files, templates, and ISO images.  They can Read More…

ESXI Storage introduction Part I

ESXI storage introduction
 ESXi hosts support host-level storage virtualization, which logically abstracts the physical storage layer from virtual machines. The following storage technologies are supported by ESXi: Direct-attached storage  internal hard disks or external storage systems attached to the ESXi host through a direct connection using protocols such as SAS or SATA. ThisRead More…

vSphere Networking : Virtual Switch VSS

Standard Virtual Switch VSS introduction standard switch (sometimes called vSwitch) is created by default when ESXi is installed.

Virtual Machine Files Structure

introduction
When you create a virtual machine, ESXI creates a set of files for that specific virtual machine. Virtual machine files are stored in either the virtual machines directory or the working directory : Both directories are typically on the host system. this is small article that will give you some details about VM file structure 
Where VM files located
