To address this issue, the storage industry has proposed a new Advanced Format (AF) drives which use a 4K native sector size. The storage industry is hitting capacity limits with 512N (native) sector size used currently in rotating storage media. However, there is still a LUN connectivity limit that needs to be considered, so if host-to-LUN connectivity limits increase in future releases of vSphere, VMFS will also be able to support increases host connectivity. ![]() With improvements to the heartbeat metadata area on VMFS-6, there is now support for up to 1,000 hosts connecting to the same datastore. This is a two-fold increase from previous versions of ESXi where the number of devices supported per host was limited to 256. DevicesĮSXi hosts running version 6.5 can now support up to 512 devices.
