Object Storage, Block Storage, and File Storage – vSAN Architecture | vSAN


Hola, yo soy Elver Sena Sosa and now
we’re going to talk about objects in particular how they relate to vSAN as
you may know objects are the next thing in storage where objects allows you to
be able to tow the array or your storage entity hey listen I want you to store
these blocks over here for me but I also want you to provide this protection or
striping and so forth so there’s metadata that you can include in the
objects that the other rate continues to provide you those that SPBM right so the
story’s policy rate management so how those the objects relay to be sent well
we first need to start with a VM and as you know a VM is composed of files and
the most or the most common files IBM has are the vmx that’s a file MB RAM is another one although many
people forget about that one that’s actually important file that’s why your
BIOS add the BM decay yeah that’s kind of critical file there there’s logs all
right let’s see the swap file is there a snapshot so when you do the delta file
right that’s one as well if you take the memory write the Delta memory of the
snapshot memory that’s another file so these sort of files that that veam has
and there are more but this will give you the gist of what we want to discuss
in this video and how does vSAN translate this files
into objects which are then placed in your vSAN data store down to the disk
groups and it’s rather not too hard to understand how this is done and the way
that I’d like to think about it although there’s not 100% accurate is to ask
yourself how big are these files are they big files or small files for
example your vmx file your mb ram file your load file does a kind of small file
so we’ll get back to those in a second the veam decay file yeah that guy is big
so that guy is going to be an object all in itself
that’s one your swap file yeah that can be big
that’s not an object your Delta your veam you know your snapshot yeah
anytime you do one of those guys you create another object congratulations
memory you’re taking your memory when you take the snapshot and know there are
object right so I’m hoping you’re getting to gist here If your VM file
is rather large B sin is going to consider that to be an object again not
hundred percent accurate a significant and a good way to kind of remember this
stuff and now let’s go back to the small files like the vmx file nvram the
log file what vSAN does is that it takes this files right here all those
files and he puts them together into something called the VM home and guess
what yep you got that right that’s also an object so that’s how objects relate
to vSAN and your VM everything in VM has to be translated into an object and
now that you had this you can proceed to be providing SPBM policies to your VM
again yo soy Elver Sena Sosa thank you for watching the objects video
