Primary Storage Question
Hi,
Does anyone know if we are aware of any technical or practical limit to the
number of Primary Storages in a given cluster, pod, or zone for CloudStack
3.x or 4.x?
For example, would 1,000 be OK? How about 10,000?
Thanks!

Hey Mike,
Are you just asking from the software side of CloudStack? I'm still a bit new to all of this so I'm not the best person to answer from that perspective. However, I believe there are limitations on the # of datastores/LUNs that can be presented to the hypervisor (be it VMWare or Xen) that would limit the # of primary storage volumes you present to a cluster.
Not sure if that answers your question, but maybe somebody else can chime in who knows more :)

>From the looks of it both VMware and XenServer share a limit of 256 LUNs per host and/or HBA. I don't believe KVM has any built-in limit, especially in the way in which it's accessed via CS, but there are practical limits as well. This may have more to do with the filesystem on top of the LUN (e.g. GFS2, OCFS2, CLVM -- not really a filesystem but you get what I'm driving at).

I think it's really a hypervisor limit (which means it will be
different for each one), not necessarily a CloudStack limitation -
technically CloudStack only keeps a record in the database and sends
commands to the hypervisor to interact with storage.
