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
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

A complex password is a firstmost requirement for any system that simply uses username/password (no RSA, 2Factor authentication kinda thing) for authentication. For a windows or unix/linux based systems, system administrators used to push complex password requirements via AD/LDAP.
The ESXi Shell provides access to maintenance commands and other configuration options. Esxi shell and SSH comes in handy when there are certain tasks that can’t be done through the Web Client or other remote management tools.
Enabling local and remote
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
To authenticate against vCenter SSO, solution users uses certificates to establish a secure connection. A solution user presents the certificate to vCenter SSO in 3 cases:
- When solution user authenticates against sso for very first time.
- After a reboot, and
The data that travels between clients and ESXi hosts is encrypted to ensure that the transactions are private and authenticated. The SSL is used to create a secure connection between the clients, ESXi hosts, and/or the vCenter Server. Read More
To improve security in your virtualized environment, it is advisable to use the signed certificates because ‘self-signed’ certificate will not be trusted by default in it’s communications with other systems. There are various ways to deploy signed certificates on your Esxi hosts
VMware Endpoint Certificate Store (VECS) serves as a local repository for certificates, private keys, and other certificate information that can be stored in a keystore. You can decide not to use VMCA as your certificate authority and certificate signer, but you
vSphere 6.0 brought many enhancements with it and one of the most significant among them was VMware Certificate Authority which is VMware’s own CA and it eases the pain of certificate management in vSphere 6.
