Misc ESXi 5x Qs..

[kiran123i]

Hi,

Hows does the esx takes the time zone from ?

Thank

ESXi uses UTC by default. If you want to change the timezone you will have to sync the ESXi server with NTP.

Thanks Abhilash ! That makes sense

Vfat filesystem is the easiest way to share data between Linux and the somewhat limited Windows-world.

Here is the link for detail information about Vfat filesystem

Does Vmware have any formal reason given for this ?

[tomtom901]

The only reason you see multiple entries is because VMware partitions the disk with seperate partitions for different parts of the filesystem. You can view VFAT as an extension on FAT. As far as a formal reason goes, I think part of this grew over time, and it could have been a different type just as easy. I think they just chose VFAT.

As far as I know, there is no raid implemented in the ESXi partition layout.
