1. Storage

2. Practical Test
 VMs
 5 x Linux minimum + OpenVPN Server/Client + tcpdump
 Proxmox (?)
 2 x Windows + OpenVPN client + wireshark
 1 x Linux desktop + wireshark
 Containers
 5 x Ubuntu/CentOS + tcpdump
 2 x Host (1 laptop : wifi + wired, 1 desktop/laptop [1
wired]/removable disk ) + CAT 6 cable
 VMWare
 Wireshark
 MS Office
 Internet

3. Storage type
 Block level storage
 Raw images
 Clone/Snapshots
 File level storage
 (POSIX) file system
 Object storage
 Data
 Thin Provisioning

4. Storage
 https://pve.proxmox.com/wiki/Storage
 pvesm
 /etc/pve/storage.cfg
<type>: <STORAGE_ID>
<property> <value>
<property> <value>
 Volumes
 Volume Ownership
 local:230/example-image.raw

5. RBD/Ceph
 https://pve.proxmox.com/wiki/Storage:_RBD
 distributed object store
 performance, reliability and scalability
 thin provisioning
 resizable volumes
 distributed and redundant (striped over multiple OSDs)
 full snapshot and clone capabilities
 self healing
 no single point of failure
 scalable to the exabyte level

6. Small deployments
 Ceph services  Proxmox VE node
 https://pve.proxmox.com/wiki/Ceph_Server
 https://pve.proxmox.com/wiki/Storage:_RBD
 Configuration
rbd: ceph3
monhost 10.1.1.20 10.1.1.21 10.1.1.22
pool ceph3
content images
username admin
 Authentication
mkdir /etc/pve/priv/ceph
scp <cephserver>:/etc/ceph/ceph.client.admin.keyring
/etc/pve/priv/ceph/<STORAGE_ID>.keyring
