Re: Block and NAS Services for Non Linux OS

Hi Steven,

 

Until the RBD/FS drivers are developed for those particular OS’s you are forced to use a Linux server to “proxy” the storage into another format which those OS’s can understand.

 

However if you take a look on the Dev mailing list, somebody has just posted a link to a Windows CephFS driver, with the potential for there to be a Windows RBD driver sometime in the future.

 

I believe the ESXi Driver API’s are available, so who knows, somebody may develop a native ESXi driver in the future too.

 

But in the meantime if you are worried about scale, you can always make use of multiple proxy nodes to spread the load across more hardware.

Hello Eneko;

 

Firstly, thanks for your comments!

 

You mentioned that machines see a QEMU IDE/SCSI disk, they don't know whether its on ceph, NFS, local, LVM, ... so it works OK for any VM guest SO.

 

But what if I want to CEPH cluster to serve a whole range of clients in the data center, ranging from ESXi, Microsoft Hypervisors, Solaris (unvirtualized), AIX (unvirtualized) etc ...

 

In particular, I'm being asked to create a NAS and iSCSI Block storage farm with an ability to serve not just Linux but a range of operating system(s), some virtualized, some not . ...

 

I love the distributive nature of CEPH but using Proxy nodes (or heads) sort of goes against the distributive concept...

Warmest Regards

My understanding for CEPH is the block and NAS services are through specialized (albeit opensource) kernel modules for Linux.

What about the other OS e.g. Solaris, AIX, Windows, ESX ...

If the solution is to use a proxy, would using the MON servers (as iSCSI and NAS proxies) be okay?

Virtual machines see a QEMU IDE/SCSI disk, they don't know whether its on ceph, NFS, local, LVM, ... so it works OK for any VM guest SO.

Currently on Proxmox, it's qemu-kvm the ceph (RBD) client, not the linux kernel.


What about performance?


It depends a lot on the setup. Do you have something on your mind? :)

Cheers
Eneko
