In the past you needed to run a command to reclaim the blocks, now this has been integrated in the UI and can simply be turned on or off. In other words, storage capacity is reclaimed and released to the array so that when needed other volumes can use these blocks. Note that this is based on VAAI Unmap which has been around for a while and allows you to unmap previously used blocks. If you want to know more about SE Sparse, read this great post by Cormac.Īutomatic Space Reclamation is something that I know many of my customers have been waiting for. When on VMFS 6 the default will be SE Sparse.

Hopefully we will have more on full support for 4Kn for vSphere/VSAN soon.įrom an SE Sparse perspective, right now SE Sparse is used primarily View and for LUNs larger than 2TB. As of vSphere 6.5 this is now fully supported but note that for now it is only supported when running in 512e mode! The same applies to Virtual SAN in the 6.5 release, only supported in 512e mode. This basically means that 512 byte sectors is being emulated on a 4k drive. Sizes of spindles keep growing and these new “advanced format” drives come with a 4K byte sector instead of the usual 512 byte sector, which is primarily for better handling of media errors. Lets look at them one by one, I think support for 4K native drives in 512e mode speaks for itself. Support for 512 devices and 2000 paths (versus 2 in the previous versions).
