Hello friends!
I want to open up a debate - well, I was hoping to - about the iSCSI disc space assignation. The thing is: let's say that I have a server with several storage spaces and that server is connected to PVE. For the purpose of this, let us not go into the matter how they are connected, does not matter. Also assume, that there is no actual (HA or software) failover for this connection - either it is there or it is not.
Now what I am interested in is this - I have iSCSI storage available and either I can give that (entire) storage to PVE, assign LVM on top of it and then add parts of it to VMs to be used. But I also could do it so, that I dived up that storage on storage server itself and then connect those parts to VMs themselves directly.
Question is now - what would be most significant or I would even say, smart, thing to do? The traffic would be in terms of more or even a lot of small requests to write and equal read to almost no huge sustained requests to it.
As I say - I want this to be pure iSCSI division debate - no speed issues, depends on this and that or similar - I stated the request types/speed. I just wanted to know, if a for instance I have 5 VMs, and I connect 1TB storage to each (division on storage server) or I attach 5TB storage to PVE and create 5 VM on it.
Thank you in advance.
Good day,
D
