My question, is a theoretical one about how vmotion / vsphere treats ISCSI Luns<br />
<br />
We have 3 ESX hosts, and we plan on using 6 iSCSI Luns<br />
<br />
system disk - high priority<br />
data disk - high priority<br />
etc, etc, <br />
<br />
Question is, if we have multiple hosts attached to the same lun, i.e System disk - high priority and then we vmotion a vm from esxi1 to esxi2 then essentially both hosts would be writing to the same iSCSI Lun. &nbsp;We've read that multiple hosts writing to the same Lun can cause corruption. &nbsp;Can someone straighten us out? &nbsp;Is this the case? &nbsp;If so, what is the recommended configuration or a small example?

VMware VMotion / ISCSI

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
