These sorts of cards have been available in one form or another for more than 20 years, and yet they still have limited market share -- not because they are fast, but because the other limitations carry more weight. If the stars align and redundancy above the block layer gets more popular, then we might see this sort of functionality implemented directly on the mobo... at which point we can revisit the notion of file system. Previous efforts to do this (eg Virident) haven't demonstrated stellar market movement. -- richard You mean presto-serve :-) Putting data on a local NVRAM in the sever layer, was a bad idea 20 years ago for a lot of applications. The reasons haven't changed in all those years! For those who may not have been around in the "good old days" when 1 to 16 MB of NVRAM on an s-bus card was a good idea - or not http://docs.sun.com/app/docs/doc/801-7289/6i1jv4t2s?a=view Trevor _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss This email is confidential and may be legally privileged.
