My apologies to everyone on this forum. The statement below was an overreaction to a legitimate issue that was raised with regard to performance on our filers.
My general comment is that if the performance of the filer seems inadequate for your application, we'd be interested in getting the specifics so we can either address the issue, or explain how to tune things so you can get the performance you need.
There's a tremendous amount of variation depending on the workload, network configuration, etc. etc., which makes it difficult to make blanket statements about the relative performance. In general, we have the expectation that the filer should perform similarly to local disk. Sometimes faster, and there may be situations where it's slower.
Sorry for the overreaction and "blanket statement" on my part

You are still limitted by the network and netapp will not be able to compete with products which provide direct disk attachment. Products in mind are SANergy and CXFS. Below is a message from a user who supports my assumtion that you cannot get local performance over a network link.

I do not get performance on par with my perception of local disk storage. Would you care to elaborate on what you mean by "on par with local disk storage"?
When I run Usenet news spools from Solaris 2.6 on a NetApp filer, I must throttle NFS to get it to work reliably. "

Network Appliance's current customer experience is that they do get performance on par with local disk storage already.
Our current plans do not include any interoperation with the SANenergy products.

I am currently investigating the market for nas storage. What is netapp plans in providing a solution which will deliver local disk performance for nas storage? Does netapp have plans for products with SANergy functionality or performance?
