Great, thanks for the info, Marcus. I'm new to both CloudStack and SolidFire, so I'm trying to get my head wrapped around the work I will need to do. On Sun, Jan 13, 2013 at 9:11 PM, Marcus Sorensen wrote: > More to your example, there is no cloudstack controlled iops or performance > setting c

More to your example, there is no cloudstack controlled iops or performance setting concerning storage (yet), but what an admin could possibly do is define a primary storage that is 'regular performance', tag it something, like 'lowperf', then define a primary storage that is high performance, tag

Another thing I was curious about (and perhaps someone on this list can answer) is if, say, Xen is running one VM from one virtual volume (equal to a LUN, in this scenario), can an app running in this VM access a data volume from a different virtual volume? So, the VM is running off of one virtual

I'm not super familiar with all of the xen setup, but anything xen supports as an SR should be usable in presetup mode. On Jan 13, 2013 10:48 AM, "Sebastien Goasguen" wrote: > > On Jan 11, 2013, at 9:22 PM, Marcus Sorensen wrote: > > > On the KVM side, you can do NFS, Local disk storage, CLVM (

Looks like with iSCSI you give it the dns name of your target, the IQN, and the lun #. Presuably it sets up an SR from that lun and carves volumes out of that, similar to how the CLVM works. Or maybe it puts a filesystem on it and mounts it, not sure. On Fri, Jan 11, 2013 at 1:22 PM, Marcus Sorens

On the KVM side, you can do NFS, Local disk storage, CLVM (shared block device that has Clustered LVM on top of it, a primary pool is a particular volume group and cloudstack carves out logical volumes out of it as needed), and RBD (RADOS Block devices, Ceph shared storage.

So, being new to CloudStack, I'm not sure what kind of storage protocols are currently supported in the product. To my knowledge, NFS shares are what CloudStack has only supported in the past. Does CloudStack support iSCSI targets at present? Thanks! On Thu, Jan 10, 2013 at 3:58 PM, Mike Tutko
