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

one)


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

Tonci Stipicevic
