I think what you want is a proper storage array with mirrored write cache.
Which is what we have with ZFS + SSD-based ZIL for far less money than a NetApp.
not unless you have a pair of them configured as an active/standby HA cluster, sharing dual port disk storage, and some how (magic?) mirroring the cache pool so that if the active storage controller/server fails, the standby can take over wthout losing a single write.
This is definitely tangental to what I was originally asking. :)
I'm not suggesting this perfectly replaces (or even comes close) a clustered NetApp setup. But it can provide similiar NFS write performance and I can buy three of them and replicate data for DR needs for far less than the price of a NetApp SnapMirror setup.
