Hi All

I am considering storage nodes for my small production deployment. I have
rejected Ceph as I cant get confidence that performance will be Ok without
SSD drives.

I need to be able to boot from block storage, do live migrations and create
snapshots which could be used to create new instances. From the
documentation, all this is feasible with LVM volumes. Ideally I wanted to
use unified storage so I can have block and object on same node.

What I would like to know from those using LVM storage nodes is the
preferred set-up as I need a minimum 6Tb block storage and wonder whether I
could use local cinder-volumes on each compute node and a central swift
storage server for 'cinder backups',

Networkiis all 10gbe.

Can I share these volumes across my compute nodes or is it better to only
use local volume on each nodes for running instances from block storage on
that node.

Overall I am expecting to require about 80-100 concurrent instances [VMs]
across two compute nodes. along with this will be multiple controller nodes.



Regards
Ian
