In our conclusion of High Availability article , we have mentioned one disadvantage of HA : which downtime We said that downtime normally 5 minutes and could be extended to 10 minutes , which could be acceptable for some VMs But unfortunately In some high critical application VM , it’s NOT acceptable >> so we have to find a solution that could decreRead More…
introduction
in previous article : we have seen how to configure and test HA in this article : we will advanced feature of HA and expert recommendation just to mention
you are NOT obligated to practice all advanced HA features below
just try practice whatever you see important for your environment

as we usual do in all our configuration , it;s better to understand network diagram to ease Read More…
DRS introduction
in previous article : we have used vMotion to Manually migrate VM from ESXI host to another and from Datastore to another its good feature : the bad thing it’s Manually let us to suppose ESXI151 get overloaded in CPU or RAM > then some VM will stop working , unless we Manually migrate VM to another ESXI we need some feature that automatically moRead More…
introduction in previous article vMotion Part I here : we have explained the concept of vMotion in this article : we will practice vMotion in many perspective we will move VM file from local storage to ISCSI remote shared storage > storage vMotion then we will migrate running VM ut self from ESXI153 to ESX151 vMotion Setup LAB Read More…
introduction
sometimes you need to move VM from host to another or from DataStore to another , because of many reasons linke : lake of host resources : CPU ,RAM insufficient space maintenance purpose troubleshooting purpose VM could be online running or suspend or even offline , shutdown Migrating a virtual machine [vMotion ] meansRead More…
VDS introduction Vswitch [which was configured previously on three ESXI ] was standard VSS è which require us to do same settings on three ESXI HostsAnd change on one ESXI host à should be done also on same ESXI host à to avoid error configurationVDS [Virtual Distribution Switch ] is centralized management of VswitchAn Enterprise Plus license is required to add a host to a v Network DiRead More…
introduction in previous articles here : we have discuussed how to create VSS virtual standard switch and how to create port group to manage multi network traffic types this article considered as complementary to that article so please make sure you have understand previous article before diving here today we will talk about some advanced topic of VSS : Switch network security poRead More…
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…
NFS network Diagram ESXI NFS network diagram as we do always in networks pioneers : it’s better to have a a look to network diagram above to understand the concept we have Suse Linux Enterprise Server as NFS Server name SLES123.pioneers.lab management ip address 172.16.100.123 connected to DMZ called [server farm ] another NIC connected to DMZ witRead More…
NFS server Steps
Configure SLES123 as NFS server include the following step: install NFS services start and enable NFS service create firewall rule on SLES to pass service NFS create folder /store/DS05 [you can set any name ] and set permission share folder /store/DS05 export file verify NFS folder exported Step 01 : install paRead More…
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…
Note : before move to ISCSI configuration : please see previous article here ISCSI Network Diagram For Better View > Open Image in different TAB to understand ISCSI – lets to have a look to Pioneers Diagram above we have windows server called iscsi103 with RIAD HDD with capacity 15TB interface for management with DMZ [Read More…
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…
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
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…
Standard Virtual Switch VSS introduction standard switch (sometimes called vSwitch) is created by default when ESXi is installed. Like its physical Ethernet counterpart, a standard switch works at layer 2, forwards frames to other switch ports based on the MAC address, and supports features such as VLANs and port channels. Standard switches have to be connected to the ESXi host’s phRead More…
introduction For Better View > Open Image in different TAB in previous articles [ ESXI best practice ] , we have mentioned that there so many network traffic between ESXI host , including but NOT limited to : network traffic to manage ESXI host it self : either by web client or by vcenter application network traffic to move VM from host to another , which called [ vMotion ] netwRead More…
introduction After we install vCenter Server, we have to access vcenter and Consider these post installation options before adding inventory for the vCenter Server to manage , like licensing vCenter create Datacenter Create Cluster vCenter License When you install a vCenter Server system, it is in evaluation mode. An evaluation mode license of a vCenter Server system expiresRead More…
introduction before start vcEnter installation : I found it ‘s better to make some comparison between vcenter as basic installation and best practice deployment this article aim to give you an overview about new concept in vcenter in advanced mode , if you can understand about 50:% of these advanced concept : it’s more than enough because we will fully cover these features in next cRead More…
introduction in previous article : we have got some brief intro about vCenter and we differentiate between [basic installation] VS [best practice deployment ] in this article we will start installation vCenter 6.7 as VCSA it’s good idea to look at network diagram below For Better View > Open Image in different TAB we have 3 ESXI servers as the following ESX151 with IP 172.Read More…
introduction previously : we have discussed how to manage ESXI server and we mentioned that the good tool is vsphere web client like https://172.16.100.151 but also we mentioned that the great and magic tool is to use Vcenter so … what is Vcenter ? vCenter Server is an application that enables you to manage your vSphere infrastructure from a centralized location. It acts as a ceRead More…
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
