We are running a 12bay Synology NAS with 5HDDs (RAID5 diskgroup) on which we have one LUN which is attached to our vshpere cluster with an ISCSI trunk (unimportant data on it) . So far so good. Now we added 4 additional HDDs to the NAS and want to use the additional space for a new backup system. For the network side aswell as the disk group side we now possibilities to set that up now. We don't know which way is best practice. For example:
For the diskgroup part:
- Add the 4 Disks to a new RAID5 diskgroup and use it as Backup diskgroup (we then have two diskgroups on the NAS)
- Add the 4 Disks to the existing diskgroup, setup a new LUN for the backup
For the network part:
- Use the same Ethernet Trunk (2NICs= 2000 mbit/s) for vsphere and the backup system
- Use the free NIC 1000 mbit/s dedicated as new ISCSI Port for the backup system
What is the best way and why? Thanks everyone in advance!
