  • 1.  Remedial Question on Network Basics

    Supporting an existing deployment w 4 ESXi 3.5 hosts, an iSCSI SAN, a physical tape server, a physical VC server, and two trunked Cisco switches. Current configs show VLANs and subnets for iSCSI, LAN, and VMotion/Svc Console. Current Tape and VC servers are configured w sufficient NICs for redundant connections to each of the three subnets.

    I am deploying two new physical servers to replace Tape and VC. And after that is done I plan to replace the ESX 3.5 on each host w ESXi 5.5. Which subnets do Tape and VC actually need to connect to? Tape doesn't really need a connection to iSCSI to back up VM's, or a connection to the VMotion subnet, does it? Does it really only need to connect to the LAN? And with VC, it also does not need a connection to iSCSI, does it? VC just needs to get to VMotion subnet and to LAN subnet, correct?

    Your VC server will need to have address on you Service Console subnet and LAN subnet - this will allow VC to communicate to the ESXi hosts and for you able to connect the VC server - however is you can route to the Service Console network from you LAN than you will not need the VC server to have a LAN IP.

    Tape server will depend on what type of back up software you are using and how you do your backups -

    Thx. You mean just add a second IP address for the Service Console subnet to the LAN NIC?

    Backups are by virtual machine, thru vCenter with Backup Exec & VMware agent.

    You could do that or if you are able to route between your LAN and Service Console subnets then you will not have to do that -

    I am not sure about your backup solution - you will have to check with Backup Exec and see what components need to communicate - I would assume it will need to communicate at a minimum to vCenter -
