Hello,<br />
<br />
We are currently running a thin provisioned SAN back-end with a thick provisioned VM environment. &nbsp;I'm trying to understand how this works / the logic behind it. &nbsp;Is the SAN essentially saying &quot;I'm going to give VM a logical block, but I will only account for what is used&quot; and then the VM env is saying &quot;oh I have this whole block of storage, I'm going to take it all&quot;?<br />
<br />
That is the scenario that I laid out in my mind, but I'm looking for confirmation as to what is actually happening here.<br />
<br />
Thanks in advance!

Hello,

We are currently running a thin provisioned SAN back-end with a thick provisioned VM environment.  I'm trying to understand how this works / the logic behind it.  Is the SAN essentially saying "I'm going to give VM a logical block, but I will only account for what is used" and then the VM env is saying "oh I have this whole block of storage, I'm going to take it all"?

That is the scenario that I laid out in my mind, but I'm looking for confirmation as to what is actually happening here.

Thanks in advance!

Thick VM with thin SAN?

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.

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

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
