Please help with Proxmox VE 9 Cluster and Alletra B10000 Via iSCSI

[RonRegazzi]

Of course, this is my first Proxmox anything and I'm going for the gusto. I have the cluster built and now trying to attach an HPE Alletra Storage MP B10000 as the shared disk for VM storage in order to achieve HA. Please forgive me, but I have been googling for days and haven't found much. Any and all tips/help will be greatly appreciated.

The Alletra config is mostly complete with the host definition the only remaining item. The ports for this SAN are configured for iSCSI and have the following addressing:

N:S State IPAddr Netmask Gateway
0:4:1 ready 10.10.10.11 255.255.255.0 0.0.0.0
0:4:2 ready 10.10.10.12 255.255.255.0 0.0.0.0
1:4:1 ready 10.10.10.13 255.255.255.0 0.0.0.0
1:4:2 ready 10.10.10.14 255.255.255.0 0.0.0.0

The servers are HPE Proliant DL380 gen11, each having two 4-port NICs. Multipath-tools is installed. The plan is to use one port from each NIC with IP address each as follows:

Host 0
Port IP Address Netmask
ens15f1np1 10.10.10.20 255.255.255.0
ens14f1np1 10.10.10.21 255.255.255.0

Host 1
Port IP Address Netmask
ens15f1np1 10.10.10.30 255.255.255.0
ens14f1np1 10.10.10.31 255.255.255.0

This will be the first thing that needs to be resolved and I have a questions about how to do this. Should the raw ports be assigned the addresses or should some type of bonding and switching be employed? If bonding and switching, any suggestions would be appreciated.

After the ports are configure, I understand the multipath will have to be configured. Finally, an LVM over iSCSI will be created.

Thank you for your time.

Hi @RonRegazzi , welcome to the forum.

Most of your questions regarding best practices should be addressed in your storage vendor's documentation. Many storage vendors recommend using multiple subnets as best practices.
That said, you may find this article helpful: https://kb.blockbridge.com/technote/proxmox-lvm-shared-storage/

AFAIK Multipathing is the preferred method to address iscsi over bonded interfaces as it is completely agnostic to the network configuration and features- but bonding can work as well. if you DO want to use bonding make sure both ends (host and target) are bonded in an equivalent fashion.

BTW, this generation of storage supports NVOF, which might be preferrable to iscsi.

Thanks @bbgeek17 and @alexskysilk!
