Max Ram and HDD for VM on esx 3.5?

[markuk]

Hi,

Is the maxium amount of disk HDD you can assign to a VMHDD 256GB and is the maxium RAM 65532mb?

Is there any way of changing this?

Thanks

Mark

Hi Mark,

For the config max you'll find the answers in http://vmware.com/pdf/vi3_35/esx_3/r35/vi3_35_25_config_max.pdf

If you need a bigger vmhdd, then you'll need to format the vmfs with a bigger block size. This should give you the ability to create larger files / vmhdd.

Good Luck

if you are limited to 256Gb VMDK then you have created your VMFS partition with default 1Mb block sizes you will need to reformat the partition if you need a bigger block siz, this can be done via the VIC or via the command line, using the following command.

vmkfstools -C vmfs3 -b 2m -S volumename vmhba1:0:0:x

where -b is

1m = 256Gb

2m = 512Gb

4m = 1024Gb

8m = 2048Gb

and -S is the name you wish your storage array to be know to ESX,

and vmhba relate to the id of the LUN.

Remember that you will format your partition, destroying any data currently on it.

You could increase the effective HD size by allocating multiple 256GB VMDKs and using a volume manager such as LVM, ZFS, SVM, VxVM, etc on the VM to create 1 volume out of the pieces. Or use RDM.

64GB RAM IS the max, no way of changing that. If you need more, your app probably isn't a good virtualization candidate anyways.
