I'm looking for alternatives SSD options to the Intel X25-E and the ZEUS IOPS.
The ZEUS IOPS would probably cost as much as my entire current disk system (80 15k SAS drives)- and that's just silly. The Intel is much less expensive, and while fast- pales in comparison to the ZEUS. I've allocated 4 disk slots in my array for ZIL SSD's and I'm trying to find the best performance for my dollar. With that in mind- Is anyone using the new OCZ Vertex 2 SSD's as a ZIL? http://www.ocztechnology.com/products/solid-state-drives/2-5--sata-ii/performance-enterprise-solid-state-drives/ocz-vertex-2-sata-ii-2-5--ssd.html They're claiming 50k IOPS (4k Write- Aligned), 2 million hour MTBF, TRIM support, etc. That's more write IOPS than the ZEUS (40k IOPS, $$$$$) but at half the price of an Intel X25-E (3.3k IOPS, $400). Needless to say I'd love to know if anyone has evaluated these drives to see if they make sense as a ZIL- for example- do they honor cache flush requests? Are those sustained IOPS numbers? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
