Re: dvSwitch configuration
No, you will create a port group for each VLAN. You can create a third VDS (or use a VSS) for MGMT if you really want, but you are also fine to continue making a port group for each VLAN on the...
View ArticleRe: Multiple distributed switches or multiples LAGs? - Best practice please?
I think either one is effective as long as your upstream switches support multi-chassis ether channel like Cisco VSS or VPC.If you don't have multi-chassis etherchannel I would look at either running...
View ArticleRe: Multiple distributed switches or multiples LAGs? - Best practice please?
It's only from the management point. You can run all of them on one or on multiple switches. If you run all traffics on one switch you will make sure that the NICs that are used for one functionality...
View ArticleRe: Multiple distributed switches or multiples LAGs? - Best practice please?
Thanks for the replies. I agree that there probably isn't one correct answer and it is dependent on infrastructure architecture. Because of the way our network is architected with multi-chassis ether...

I am considering this too. It is a bit of a mental call for me. I truly believe 5.5 has brought a lot of checks and balances to have the management network on it. Still in the back of your mind you are...

Hi, the eth0 on the centOS VM is the virtual NIC which is needed to connect to the virtual switch on the ESX so that VM traffic will reach the vSwitch but from vSwitch you need a up link which will...

Would it be beneficial to enable Jumbo frames from the isolated SAN switches to my Vmware Hosts, but leave everything else as standard? Or would that cause issues? Any help would be appreciated. So...
View ArticleRe: Jumbo Frames
For Jumbo Frames to be used in a network, all components (end-to-end) need to support it. There's no benefit with enabling them only on the switches. However - to answer your question - it should cause...

Sorry, one more question. I would have my Compellent SAN NIC's set to Jumbo, the VMware vmkernel ports set to jumbo as well as the isolated switches between. So i can vmkping from the esxi host to the...

Yes, it should work if the complete "chain" (port group, vSwitch, physical switch, storage) is configured for Jumbo Frames. You can verify whether Jumbo Frames work without fragmentation by running...

That seems extreme. You should have regular backups of your vCenter database that you test and validate in the case of a complete loss of vCenter. As for outages, the ESXi hosts all cache a copy of the...
View ArticleRe: Failback when using Etherchannel and FCoE
FCoE doesn't use IP (it's a combination of FC + FCoE + Ethernet), so you can safely rule that out of the equation here. In fact, your CNA likely just exposes an HBA that is completely separate from...
