Everyone else should be using the Intel X25-E. There's a massive difference between the M and E models, and for a slog it's IOPS and low latency that you need.
I've heard that Sun use X25-E's, but I'm sure that original reports had them using STEC. I have a feeling the 2nd generation X25-E's are going to give STEC a run for their money though. If I were you, I'd see if you can get your hands on an X25-E for evaluation purposes. Also, if you're just running NFS over gigabit ethernet, a single X25-E may be enough, but at around 90MB/s sustained performance for each, you might need to stripe a few of them to match the speeds your Thumper is capable of. We're not running an x4500, but we were lucky enough to get our hands on some PCI 512MB nvram cards a while back, and I can confirm they make a huge difference to NFS speeds - for our purposes they're identical to ramdisk slog performance. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
