point them to different LUN's and you should be fine as long as you have sufficient bandwidth. In this scenario - the network link is going to be the bottleneck.... so i would hope you have 10GB - or at least a bonded channel, such as 4GB LACP link to the iSCSi endpoint.<br><br>Since its a test environment - if your not doing "heavy load" type operations, you might get away with 1GB (but i doubt it)

Hayes. i should have mentioned that the r720 has daul 1 gb for vm management and dual 10gb for iscsi and vm traffic.

Any shared storage will give you options to Lab Shared Storage Functions in your Lab.<br />

Install FreeNAS and create iSCSI LUNs.

you may well use iscsi for the nested ESXs. the system-related traffic will drop next to zero shortly after boot.<br><br>the inner guest vms can either directly use iscsi or the local store. either way, that's one iscsi xfer. the former is a bit faster because there is one less layer of virtualisation, but barely : the local virtual io layer has neglectible performance impact compared to iscsi anyway.<br><br>depending on your goals, both are meaningful. separate targets are good to experiment with vmotion, local is better if you plan good I/O perfs on barebone and want to check what you need still works decently with local storage. other setups might be meaningful depending on the usage of the lab. in doubt, use separate iscsi targets for each guest or nested guest.

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

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

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.
