DX200 S4
8 disks 950 GB
5 disks 3.90 TB
the goal is to give it all to proxmox in the form of two independent LVM over iSCSI.
4 ports on DX200 - 4 IP addresses,
two panels (in case of failure) CM00 and CM01, two ports each.
As I see:
- create 2 Thin Provisioning Pools for two RAID GROUP (RAID5 of 8 disks + RAID5 of 5 disks)
- create 2 Volumes (Thin Provisioning Volume) Host Group for the right servers Port Group - each of the 4 ports is its own node1, nod2, node3, node4.
- create 2 Port Group in which all 4 ports.
- LUNs for each Volume
- create 2 Host Affinity. Host Group - CA Port Group, each corresponding to Host Group, CA Port Group, LUN Group.
questions:
- do I need deduplication/compression or are these extra costs?
- make two nodes instead of four?
- perhaps it is necessary to do it somehow differently, because I do not yet understand how to configure both LUNs in multipath in proxmox, if into account that each LUN hangs on all ports / targets / nodes, or it is necessary to separate, attach one LUN Group on one panel (CM00) with only two ports, and the second on the other (CM01), but will there be problems if one of the CMs fails?

When there was 1 RAID, 1 Volume, 1 LUN - everything was clear, but I need two LUNs.
