Re: nutanix

You definitely bring up a great point with regards to CBO, but wouldnt that apply to exadata as wel? Sorry i have not worked on Exadata but i thought exadata had some thing similar where it his multiple flash disk and sata kind of disk and it moves the data around, i might be wrong on that, also wouldnt that same case apply to traditional model as well when we have SAN in place, as the data is caches in SGA first and then most probably in the SAN Cache and different tires of storage on SAN?.....but definitely a great point for us to keep in mind...

We are in early stage of this process and according the Nutanix rep's they have big enterprises running oracle/SAP on there system and have not seen any major issue. One other concern that i had was, they use NFS but that is not visible to the VM's that is all handled by controller VM...

Below is a great in depth blog with regards to Nutanix, for those who are interested...

_at_Karl,

You are correct....some of the co-founders of natanix worked on exadata platform and also google's File system and they call there file system - NDFS(Nutanix distributed file system)...

And yes once we get the hardware in place i am going to use SLOB and also swingbench to see how it performs.
