I'm considering adding a l2arc to my home system and was wondering if anyone had recommendations. I've also considered slicing the drive and using it for a zil and l2arc, but I don't think that my workload would really benefit from a zil. I'm running a few VMs and serving up content via CIFS mostly. I have dedup enabled, and the slow writes (presumably from the DDT getting too large) has pushed me toward using a l2arc.
I've got an 8 drive raidz2 pool, with ~ 3TB currently allocated. The server has 8gb of memory. I'm not sure how much l2arc I need to hold the DDT, but I imagine 30gb is enough. The drives I'm considering are: OCZ Vertex 30GB Intel X25V 40GB Crucial CT64M225 64GB The OCZ drive uses the Indilinx Barefoot controller and Intel 34nm MLC. From what I've read, it performs very close the the Vertex drives of similar capacity. The Intel is based on their controller and Intel 34nm MLC. Write performance is crippled compared to the "real" Intel drives, but reads still seem good. The Crucial drive is based on the Indilinx Barefoot controller and Samsung NAND. It should have performance on par with other Indilinx devices. The OCZ looks like the best deal right now at $129, with a $40 rebate. The Intel is $129, and the Crucial is $189. -B -- Brandon High : bh...@freaks.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
