Cisco  HyperFlex is hardware on top depends on model it come with pre-build  esxi and you can start building VM's

Re: HYPERFLEX, can i not use a hypervysor?

Hi vivarock12,

 

First of all, you have to undestand that a VM is a VIRTUAL machine. It does not exist on any piece of hardware by itself, it needs an underlying Operating System that "virtualises" the underlying hardware componenets - RAM, CPU, NIC & Storage (HDD/SSD).

This underlying Operating System is referred to as a Hypervisor

It is impossible in any Hyperconverged Infrastrure (HCI) to deploy a VM without  a Hypervisor of some kind. So, no, you can't use Hyperflex without a Hypervisor.  And creating a VM directly to the cluster is like trying to drive a bus without wheels. So to answer your second question: No, you cannot  create VM directly to the Cluster. 

Fortunately with Hyperflex, you get a choice of Hypervisors. You can deploy your Hyperflex cluster using either a VMware ESXi hypervisor, or a Microsoft Hyper-V hypervisor.  The entire cluster must be deployed with the same hypervisor because the hypervisor needs to have specific extensions incorporated to present the Storage component of the entire cluster as a single storage device. With VMware, the strorage device is presented as an NFS store, with Hyper-V as an SMB share.

There is also one more component that is needed whenever multiple hypervisors are to be centrally managed, and this component is even more important when a distributed storage sytem has to be presented as a single device. This component is of course the Hypervisor Manager. With VMware, this is vSphere, for Hyper-V this is (typically) Microsoft System Center.

I hope this helps

Re: HYPERFLEX, can i not use a hypervysor?

Well let me reformulate the question then.

Is it posible to install multiple OS on the hyperflex or is it just seen as one entity with one OS (Ex: ESXI) or can i have like partitions of the hyperflex for multiple OS?

 

Thanks for the help.

Re: HYPERFLEX, can i not use a hypervysor?

You need to maintain Clarity here ? Multiple OS?   you mean windows / Linux / so on ?

 

There are 2 different here :

 

One is Hypervisors - you have different available in the market, it will be installed on top of Compute hardware hyperflex provide.

 

Hyper-visors can accommodate any OS like Windows/10/2012 so on,  Also Linux Flavours. that is called VM.

Re: HYPERFLEX, can i not use a hypervysor?

What i ment is not a hypervisor of type 1 that is install directly on the server what i ment is:
Can i make partitions of the Hyperflex and install in one partitions a ESXI in another a SW in another a CentOS.

Some thing like this:

APP  | APP  |APP

SO    |SO    |SO

---   |---    | --- (with out the Hypervisor)

HardWare

The thing is can i have multiple OS install directly to the hyperflex? from what i have read it cant basicly the solutions is focus on Virtualization but i wan to know if is posible.

Re: HYPERFLEX, can i not use a hypervysor?

The answer to... 

Can i make partitions of the Hyperflex and install in one partitions a ESXI in another a SW in another a CentOS?

is easy. It is quite simply:

NO

The reason being is that Hyperflex controlls the entire storage space of every node via a Storage Controller, and the storage controller is a VM that works with either ESXi or Hyper-V. There may be other choices in the future, but it will ALWAYS be a VM, and always require a Hypervisor. That is what it was designed for from the ground up.

In fact, the whole idea of a Hyperconverged Infrastructure no matter what brand will always be integrated with a Hypervisor of some kind. Back to my bus analogy, the Hypervisor is the engine of the bus!

I hope this helps
