There are some old issues in vsphere around the total amount of open virtual disks that can be on a given host.

http://www.boche.net/blog/index.php/2012/09/12/monster-vms-esxi-heap-size-trouble-in-storage-paradise/

anyone know what the vsphere6 limits are?  Just curious as the storage for us just got a lot bigger.

Not seen any issues here, how many VMs and virtual machine disks do you have?

The article you have sited is 4 years old!

see this Vmware document

it's more if you have over 300tb of data and one or two host, so the compute in previous builds wouldn't open xyz without patch. i.e 8 or 24 or 64 at a time.. how much does 6.0 use for single host and update 2

Connect further...control easier

With the ATEN CE624, you can now enjoy a high-quality visual experience powered by HDBaseT technology and the convenience of a single Cat6 cable to transmit uncompressed video with zero latency and multi-streaming for dual-view applications where remote access is required.

Yes, I also posted that article, but quoted from the most recent published.

So 64TB or 128TB per host.

and it will change again at the next release soon.

So if you have 300TB, then you will struggle per host, at present. So I would discuss with VMware Support.
