my small design is based on 2xXenServer DL120 G6 with 4x1Gbe ports and 1xMSA P2000 G3 with 4x1Gbe Ethernet ports (it has another controller as well but will not be used now). 5 VM machines running with no disastrous load avg. iSCSI as storage connection used.
Possibility 1:
2x1 GBe ports of XenServer1 connected to 2ports of MSA, and another 2x1Gbe ports of XenServer2 connected to MSA as well to the same controller.
Possibility 2:
2x1Gbe ports from XenServer1 and 2x1Gbe ports from XenServer2 connected to cisco switch, and all 4 ports of MSA connected to cisco as well.
My questions:
1) What will be maximal throughput to each server in both possibilities? Is it possible to set some kind of bonding on MSA so there will 4gbps towards the switch?
2) Does the XenServer support this kind of load balancing with NIC bonding ?
3) What is necessary to set on Cisco in case of second possibility ?
Thanks.
