Hi to all,
I have cuople of issues:
1. ibm x3200 has HBA (host-based-adapter) LSI 1046E hdd controller that
also can handle raid10 arrays
So debian (proxmox 1.9) recognises it as raid controler and accepts
raid 10 array and sees it as one drive (made of 4) . So the lsi 1046e
driver is there.
but neverthelss debian does not provide monitoring for this controller
and we are not able to retrieve raid-health-state which could be (is)
very important !
How to aproach to this issue?
We cannot be notified in the case one drive fails...
In order to monitor riad array we can only look at the server...
Is it wise to use it (HBA hdd (raid) adapter) or not ? (since we've got
2. end-user has netapp FAS2020A as storage
So what would be optimal aproach:
1. from my point of view NFS share (for VMs and proxmox cluster) seems
to be very good. NFS is native netapp format anyway ...
but we cannot make online backups (but we could take advantages of
netapp snapshots ... every day another snapshot of hddxx.raw file)
2. if we make iscsi connection to netapp and lvm partition on top of it
than we can make online backups etc.
So I kindly ask, if somebody , that has tested pros and cons of NFS
and ISCSI towards netapp storage, can share some expirience and advices
about this proxmox-storage combination ?
thank you very much in advance
and best regards
