25 October 2012
Comments off

Reading Time: 2 minutesWith the new Windows Server 2012 there are several improvements in the storage part, expecially when we apply to a Hyper-V enviroment. The main news on the storage part, is that now is possible build a Windows Fail-Over Cluster with a shared SMB3 share and use it for store VMs (in a similar way as NFS could be use to NAS connectivity on a VMware vSphere cluster). Also a specific function (Virtual Fibre Channel) as been added to map a FC SAN LUN directly to a VM (similar to the same function in VMware vSphere). […]

Reading Time: 5 minutesVSA (VMware vSphere/Virtual Storage Appliance) is a solution, introduced in version 1.0 with vSphere 5.0, to transform local storage in shared storage. Basically a VA on each node use a local datastore to export it via NFS. But most important is also make a replication to another node.

Comments off

Reading Time: 3 minutesIn the new vSphere 5.1, there is a missing component replaced by a new one: VMware Data Recovery (VDR) has been replaced by the new VMware vSphere Data Protection (VDP). VDR was a backup solution introduced with vSphere 4.0 and based on the VMware vSphere API for Data Protection (VADP) which includes the Changed Block Tracking (CBT) technology (to have incremental backup).

Comments off

Reading Time: 2 minutesRecently I got a strange issue using a cold storage migration usign the Migrate function of vCenter Server. This was the scenario: a Free Hypervisor with some VMs where a full license (Essential Plus) was added and the host was also added to a vCenter Server.
