Calculate how much data can be transferred in 24 hours based on link speed in data center

  In case you are planning for migration via DIA or IPVPN link and as example you have 200Mb stable speed so you could calculate using the below formula. (( 200Mb /8)x60x60x24) /1024/1024 = 2TB /per day In case you have different speed you could replace the 200Mb by any rate to calculate as example below. (( 5 00Mb /8)x60x60x24) /1024/1024 =  5.15TB  /per day So approximate each 100Mb would allow around 1TB per day.

Recreating a VMFS-3 or VMFS-5 partition table in ESXi 5.x

For this kind of issues you need to engage VMware support on this, following any part of this article could lead to more complex situation if not ran by an expert.   Symptoms Datastore does not mount because of a lost or overwritten partition table.   Purpose When a VMFS partition is created in ESX 3.x or ESX 4.x, it has a Master Boot Record (MBR) partition map. The MBR is written to the first 512 B block (LBA0) and contains the information where the (VMFS) partition starts and ends. ESXi 5.0 introduced VMFS-5, which uses a GUID partition table (GPT) for new datastores. When a VMFS-3 partition is created in ESXi 5.x and is later updated to VMFS-5, the original partition map (MBR) is maintained. If the partition information of a VMFS datastore is deleted or overwritten (for example, by a Windows system with direct access to the same disks), it is impossible to determine if the partition map was GPT or MBR. The only time you can be sure that a GPT partition map was used is if th...
