if you use replication technology for a clone of your produciton network, does the DR site typically just contain a replicated SAN, or does it also include copies of all hosts as well, or can it be either, i.e. justDR &nbsp;SAN, or both DR SAN and DR hosts? <br />
<br />
Do you need DR hosts if its only your SAN that blows up? i.e. can your production hosts just use the DR SAN if they havent exploded to? <br />
<br />
My understanding was that vmware DR setups are used to mitigate the single SAN (single point of failure), but I wasnt sure if the setup typically includes a set of hosts as well?<br />
<br />
And what tools &quot;do&quot; the actual SAN to SAN, esxi host to esxi host replication?

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.

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.
