FAS and ESX : will i loose a lot using iSCSI instead of NFS ?

Hi,

 

i just learn that when you virtualize a MS Exchange you must use a block protocol. Even if ESX present NFS from FAS as a block device, it is not supported.

We have been working with ESX, FAS and NFS for years with no problem, even with many exchange servers on it !!

I read many links from there and other forum and difficult to know what to do.

 

We now have a brand new strech metrocluster (2 fas8020 and 2 DS2246), and before having it under production i'm asking myself if i should use it with NFS (which is the prefered method for ESX/FAS) or with iSCSI (which is best practices for exchange).

 

Will i loose feature/performance ?

 

Any advice is welcome

 

Many thanks

i think as you're going to use exchange, you should use ms's recommendation - using block - iscsi.

using nfs might work well too. but it is not supported by ms. so if you have some issue on ESE, you're on your own - coz ms says "we dont support it".

there's tr4221 you can read from fieldportal.netapp.com website.

 

hopefully helps

 

thanks
