It does not. However, it doesn't really matter for a cache device. The cache device is written to rather slowly, and only needs to have low latency access on reads. Most current gen SSDs such as the Intel X25-M, Indilinx Barefoot, etc. also support garbage collection which reduces the need for TRIM. It's important that you align block on a 4k or 8k boundary though. (OCZ recommends 8k for the Vertex drives.) I think that most current drives have between a 128k and 512k erase block size, which is another alignment point you can use. -B -- Brandon High : bh...@freaks.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
