Find “Zombie” VMDK files

Image
Today’s post is titled find “Zombie” vmdk files , I was recently working with a customer whose task was to find out multiple snapshots that are not displayed in the snapshot manager.
I tried a lot of time to skip this problem with consolidation of the Virtual Machine but in this scenario this solution seems that doesn’t work. The reason behind this task was that many of the virtual Machine where snapshot remove from virtual machine and the customer was not sure on how to clear up the “Zombi” vmdk files. In order to remove safely the snapshots that you see in your vCenter you have to dig a little from the esxi hosts , my choice ran it RVTools and export the vCenter report. vHealth tab that showed all Zombie VMDK’s “zombie” VMs and also listed VM’s that where named differently from their corresponding folder.

VMware vSphere Remote Office Branch Office (ROBO) Editions

I was recently working with RFP for one of the Existing customer, this project is for remote site ESXi refresh. I found there is lot of inconsistency with ESXi version. All are running with Enterprise puls and found more than 70 + sites running with less than 15 VMs.
There are various ways that we can go ahead and refresh these ESXi hosts. I found another alternate solution with cost savings called vSphere ROBO ( Remote office Branch office ) licenses which is more cost effective and licenses are provided by VMWARE with virtual machine based pack.
VSphere ROBO is 25 VM’s pack , this is applicable for sites with maximum 25 VMs only and can also be shared between sites.
Customers can purchase these editions in packs of 25 Virtual Machines (VMs). A maximum of 1 pack can be deployed per remote site or branch office. Customers can choose to distribute a pack of 25 Virtual Machines across sites (e.g., 5 VMs in Site 1, 5 VM in Site 2 etc.).
Customers can centrally manage their ROBO hosts using V…

VMFS 6 vs VMFS 5 in vSphere

Image
Recently VMware announced Vsphere 6.5 has introduced a new version of VMFS version 6 with lot of new enhancements. This topic will cover major difference between VMFS 5 and VMFS 6.

The upgrade process is slightly change, we can’t upgrade directly existing VMFS 5 volumes to VMFS 6. You have to plan and create new VMFS 6 datastores and migrate the existing VMFS 5 datastores VMs using storage vMotion. Once everything complete then ensure and deleting the VMFS 5 datastores.

Device Sector Formats and VMFS Versions
A sector is a subdivision of a track on a storage disk or device. Each sector stores a fixed amount of data. Traditional 512n storage devices have been using a native 512-bytes sector size. In addition, due to the increasing demand for larger capacities, the storage industry has introduced advanced formats, such as 512-byte emulation, or 512e. 512e is the advanced format in which the physical sector size is 4,096 bytes, but the logical sector size emulates 512-bytes sector size.
