Case of CEPH Environment Hyper-converged

[Felipe Rossi <fe...@brascloud.com.br.INVALID>]

Hi All,

I would like know if some one have case of CEPH + CS + KVM or other hypervisor in 
environment hyper-converged using CS.


Att / Regards

At PCextreme we use CEPH + KVM. Ceph can perform well, but it depends on hardware, architecture, and configurations (as any technology). KVM is the same deal, it performs well and it is stable.

Just to be clear, there are many production environments running with KVM and Ceph out there; if hyper-converged fits well with your needs it sure can be applied with CloudStack + KVM + Ceph.

In particular, Ceph needs a *lot* of spindles / CPU / network interfaces 
to run with reasonable performance. I tried just a 3-system 6-spindle 
Ceph implementation, and was getting streaming write throughput of 20 
megabytes per second. Which, uhm, isn't good, in case you're wondering. 
As in, external USB 2.0 disk drive speed not good.

Use NFS if you're doing a small installation. I did a small 2 node 
installation (1 compute, 1 file server) that way, and it worked fine.

Had exactly the case (CEPH +KVM + CS), very long time ago = just dont' do
it.... as simple as that :)

BTW, It's interesting ,these days it's called hyper-converged when you put
all things (roles) on single box - back in the days (again, loooong time
ago) this was called "we don't have enough money" :)))

As long as your hypervisor supports the hyper-converged storage system you
want to use, you are good to go. Of course, it depends on how you are going
to introduce the storage system to the hypervisor (ACS needs to know how to
handle the blocks/volumes).



Hyper-converged systems are good because you can save money with hardware
and cooling, but it brings more complexity to your virtualization stack.
They require extra care to plan ahead upgrade paths and execute them before
you find yourself in some vendor lock-in (e.g. ScaleIO and XenServer).
