DRS Automation Level and Migration Threshold

DRS migration threshold allows you to specify which recommendations are generated and then applied (when the virtual machines involved in the recommendation are in fully automated mode) or shown (if in manual mode). This threshold is also a measure of how much

Configuring EVC in vSphere 6

The evolution of vSphere has forced the hardware vendors to add more enhanced functionalities in server hardware in order to bring the best out of virtualization.  Enhanced vMotion Compatibility comes into picture when a all Esxi hosts in a cluster are not

Configuring DPM in vSphere 6

What is vSphere Distributed Power Management (DPM)

Consolidation of physical servers into virtual machines that share host physical resources can result in significant reductions in the costs associated with hardware maintenance and power consumption.

vSphere Distributed Power Management provides

Esxi Host Power Management Policies in vSphere 6

One of the advantages which virtualization brought with itself was “POWER SAVINGS” as it enabled administrators to consolidate workloads on fewer number of physical servers and thus save some power and reduce carbon footprint in the datacenter. Sunny Dua rightly mentioned in

Enable and Configure ESXi Host Lockdown Mode

To enhance the security measures in a virtualized environment, it is often advisable to limit direct access to Esxi hosts and this is when lockdown mode concept comes into picture. Lockdown mode is used on Esxi hosts in order to improve

Backup and Restore vDS Configurations

You can export vSphere distributed switch and distributed port group configurations to a file. The file preserves valid network configurations, enabling distribution of these configurations to other deployments.

This functionality is available only with the vSphere Web Client 5.1 or

Distributed Switch Port Group Bindings

In a vSphere environment where vDS is being used for networking connectivity, there are several options available for what should be the type of port binding that is to be used for a portgroup. Have you ever wondered which Port Binding setting is most

Network IO Control in vSphere 6

In this post we will discuss about what is NIOC and why we need it. We will also configure NIOC in lab. 

What is Network IO Control (NIOC)?

Network I/O Control (NIOC) was first introduced with vSphere 4.1 and it

Switch Discovery Protocols

In physical networking space, switches are connected to one or more adjacent switch forming a web of switches which can talk to each other. This web of switches is referred as “neighbourhood of switching”.

Virtual switches (standard or vDS) are connected

Configuring and Managing VMkernel TCP/IP Stacks

While working through VCAP6-Deploy blueprint I stumbled upon topic TCP/IP stack configuration. I have seen this many times in my lab while configuring networking stuffs and had a basic idea of what is the purpose of using custom TCP/IP stack. Suprisingly this

VMFS Locking Mechanisms

In a shared storage environment, when multiple hosts access the same VMFS datastore, specific locking mechanisms are used. These locking mechanism prevent multiple hosts from concurrently writing to the metadata and ensure that no

iSCSI Port Binding in vSphere 6

My first interaction with iSCSI and port binding was back in 2013 when we introduced an iSCSI based SAN (Dell MD3200i) in our environment. We were a small SMB entity and introduction of SAN

VMFS Re-Signaturing

When you create a new datastore in vSphere, each VMFS volume is assigned a unique identifier (UUID) and this UUID info is stored in a metadata file as unique hexadecimal number.
