Nevertheless, working with VMFS is like using any other technology. You can connect it to ESXi hosts and transfer files from one to another (or just store a temporary copy on an external storage device).Īs you’ve probably noticed, this approach implies connecting to host via SSH as well, but such datastore also allows using WebGui. Instead, you gotta use SSH and dive deep into the host data storage system, so you can figure I am a much bigger fan of a second way: creating a VMFS datastore on a USB drive. You cannot work with the Graphical user interface (GUI) as well. However, such an approach has some issues, the most tedious one being maximum file size limitations, which certainly limits its use for larger files.
The first one is to copy files from a USB device to a host directly through SSH session without changing drive format as the following article suggests. More specifically, you can use a drive in two different ways (by the way, both authors have my most sincere regards and appreciation for presenting these methods in a most coherent and simultaneously simple way). If a case like this occurs, a USB flash drive or USB external drive is a way to go. NOTE: Though VMware’s VMFS5 and VMFS3 support files larger than 2TB, the current maximum VMDK file size is 2048GB minus 512 Bytes.As an admin, I often have to deal with the necessity to transfer large OVF and ISO files or even move virtual machines (VMs) between ESXi hosts that have poor network performance or disposed in different locations with no network connection whatsoever. VMware recommends allowing for the following “worst case scenarios.” The snapshot file size is referred to as “overhead.” In cases where the snapshot file becomes large, the maximum size of an exported agent volume set may be smaller. The maximum exportable size is equal to the VMDK size and snapshot file combined. Also, a 1024GB volume has a maximum VMware snapshot file size of 8GB. For example, if the datastore to which the VMware export is being performed is configured with a block size of 4MB, the maximum file size is 1024GB. Limitations exist with VMware environments that dictate the size of virtual standby exports.
