how to give virtual machine direct access to iscsi LUN
Hi, In our vSphere environment, we have enabled iSCSI storage presentation from our NetApp vFiler directly to virtual machine guests. This is for database virtual machines to take advantage of NetApps...

No, just create a LUN and present it to ESX. Then add a "physical raw device mapping" in your VM, which is basically the LUN directly connected to your VM.DuncanVMware Communities User Moderator | VCP...

Thanks Duncan. So what are the pre-requisites to do this in terms of ESX networking and storage configuration ? I'm not familiar with iSCSI... Stephane

Duncan, May I dissagree with you there? (Purely for exchanging thoughts and learning about this) I 9/10 times advise the direct use of iscsi to the VM. Reason for this being the not so great...

Of course you can disagree. I don't like the administrative overhead InGuest iSCSI initiators give and the overhead on CPU for a guest. I wouldn't want to keep track of InGuest initiators for large...

I agree on the performance boost from the VI-3 point of view. But isn't the largepart of the CPU overhead you're mentioning being caught by the TSO in the "physical" NIC's? I enforce the use of the...

I use this for Exchange and all my SQL - couldn't go back now, it's such a great feature.

There's one key advantage to using the SAN vendor's host tools to connect the LUN guest-side: off-host backup using VSS Hardware Providers. It creates an app-aware snapshot (so Exchange and SQL are...

Re: how to give virtual machine direct access to iscsi LUN
In case we implement InGuest iSCSI initiators, do we need to create an iSCSI dedicated vSwitch (with vmkernel iSCSI + pnic) or does the creation of a virtual machine portgroup (in the VM vswitch) with...

Hi Stelephan, It all depends on your security design. I'd advise for having at least CHAP authentication on all machines to prevent any type of hacker on the virtual machine to gain access to other...
