[Review]: vSphere 6.5 Update 2

vCenter 6.5 Update 2

Today, VMware has announced vSphere 6.5 U2 with lot of new features and fixes on components specially on ESXi and vCenter. vSphere 6.5 U2 has some new features that backported from vSphere 6.7 . VMware recommended upgrading vSphere 5.5 to vSphere 6, 6.5, so vSphere 6.5 U2 is good choice for upgrade virtual infrastructure with less impact, because many hardware that supporting vSphere 5.5, don’t compatible with vSphere 6.7 . Upgrading to vSphere 6.5 Update 2 from vSphere 5.5 requires a minimum version of vSphere 5.5 Update 3b prior to performing the upgrade.

[Review]: Nakivo Backup & Replication 7.4 (GA)

Nakivo Backup & Replication 7.4

The below new features are added to the new version and “Automated VM Failover” is my favorite. If disaster strikes and your virtual infrastructure goes down, fast recovery is of the utmost importance. NAKIVO Backup & Replication v7.4 features VM failover jobs, which can automate and simplify the VM disaster recovery process. The VM failover jobs include re-IP and network mapping rules, which ensure that recovered VMs can function normally at the DR site. This makes the failover process automated, seamless, and entirely effortless, even in large environments.
