l2arc is not a substitute for ram. In some cases it can improve disk performance in the absence of ram, but it cannot be used for in-memory applications and kernel. At best, what you're describing would be swap space on a SSD. Swap space is a substitute for ram. Be aware that SSD performance is 1/100th the performance of ram (or worse.) Garrett is right. Add more ram, if it is physically possible. And if it is not physically possible, think long and hard about upgrading your server so you can add more ram. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
