Lefthand P4300 Multipathing/Loadbalancing with ESX v4.1
Hi,
I would like to know what the recommended Multipathing/Loadbalancing configuration for the P4300 in conjunction with ESX v4.1 is.
Ive read the "Running VMware vSphere 4 on P4000" document (http://h20195.www2.hp.com/V2/GetPDF.aspx/4AA3-0261ENW.pdf) but I`m confused anyway!
On Page 7 in the Document (Figure 5. Physical Network Adapter Failover Order for VMkernel MPIO) they recommend to use 2 VMkernel Ports each bound to one PHY_NIC, but you shouldn`t use two VMkernel Ports with IPs in the same Subnet! But except for a Multisite Cluster you can`t use VIP`s in two subnets?! The Document also says NOTHING about Bonding the P4000 NICs or not....
What IS best Practices for this Configuration?
2 P4300,
2 separate LAN Switches,
ESX v4.1 with 2 dedicated NICs for ISCSI,
vSwitch with 2 VMkernel ports bound to VMHBA33
RoundRobin Loadbalancing.
1. Bonding LH NICs or not?
2. 2 VMkernel ports in same or in different Subnets?
3. One or two VIPs?
Ive attached 2 Drawings, tested v1 on success,
tested v2 with success but 2 VMkernel Ports in same Subnet and therefore not recommended by VMware....
Thank You for help!
P.S. This thread has been moved from Disk Array to HP StoreVirtual Storage / LeftHand. -HP Forum Moderator

Re: Lefthand P4300 Multipathing/Loadbalancing with ESX v4.1
Since ESX/ESXi v4.x VMware supports two VMkernel ports with IP-addresses in the same subnet. This was formerly NOT supportet.
see: http://kb.vmware.com/kb/1013077
So My Example v2 is the right solution:
ESX side:
- 2x VMkernel Ports in same subnet.
- each VMkernel port bound one phy_NIC
- both VMkernel ports bound to the software iSCSI adapter.
- path selection policy of round robin.
P4300 side:
- both NIC adapters of both P4300 bonded.
- One VIP with Adaptive Load Balancing (ALB).
That`s it.
