Need help with this design

Hi every:

I don't know if this is the best community to post this if not apologies first. I'm planning to install 16 ESXi in this HP BladeSystem servers:

  • 16 BL460c G6 with 2P X5650 (SixCore)

  • 192GB DDR3 (each server)

  • 1 HBA 8GB Dual Port (each server)

  • 1 NIC Dual Port (each server)

  • 2 SAN Switch 8/24 (in the rear of the c7000 enclosure)

  • 2 Virtual Connect Flex 10GB (in the rear of the c7000 enclosure)

Then I need to setup in this configuration:

  • 3 virtual servers (in a subnet A)

  • 16 virtual servers (in a subnet B, the subnet A can send to subnet B but subnet B doesn't need to see subnet A)

  • 30virtual servers (in a subnet C, this canbe viewed from subnet A and subnet B)

Wich is the best vNetwork congifuration for this? Any help?

Thanks in advance

You can use a VLAN based solution (that is scalable to more network).

One single vSwitch, and different portgrops, one for each VLAN.

Hi Andre and thx for you reply but this is not what I mean. I know that for this purpose VLANs in pyshic L2 will be the best option but doesn't know how to distribute pyshic 16 NICs (from Blade servers) in order to get vMotion and load balance among all the virtual machines. I started read ESX Configuration Guide but it was not so help for me. I attached a image with simulation on my PC (using vMWare Workstation) trying to build a entire picture of the problem but doesn't know Smiley Sad

Cheers

If you have ONLY 2 NICs on each blade, you have to make a single vSwitch with both NIC attached.

Than create different portgroup with different VLAN ID on the same vSwitch.

On physical switches you have to set the port connected to the blade NICs as trunk port for multiple VLANs.

I have ONE NIC in each Blade and each of these NICs have two ports. So you mean I need to create one vSwitch for every NIC? You mean 16 vSwitch at the end? I want to configure this 16 Blades as a HA Cluster so this vSwitch approach is the better for this enviroment or not? I was thinking in resource pools but again doesn't know how Network adapters play they role here and for that is my question.

If I create different vSwitches and assing, for example, VM from subnet A to vSwitch created on Blade 1 and then VM from subnet B to vSwitch created on Blade 2 this guaranty that VM on subnet A doesn't see VM on subnet B or I need to create VLAN in pyshical L2 anyway?

So for each blade you have 2 ports? (I called 2 physical NICs)

If yes, for each backup you will see 2 adapter.

To have network availability you have to use at least 2 pNICs for each switch... So you can create one single vSwitch (on each host) with 2 pNICs.

Each host will have its own vSwitch (so for 16 blades you will have 16 vSwitches... yes).

If you have the Enterprise Plus license you can create one single DVS (in this case you will create it on the vCenter Server), but still with 2 uplink, cause each host (each blade) as only 2 ports.
