Async mirroring is nice, but I'd rather have all writes going to pairs of FC-AL disk shelves (each connected to a pair of filers too, of course).
Taking this idea a bit further, how about NVRAM mirroring. If you have a cluster that is already done on the other filer, but if you don't and the NVRAM goes to Rome there is a bit of exposure. Putting in a second NVRAM card should be considerably cheper than adding another head, although not as resiliant against DOS.
