Re: [zfs-discuss] ZIL NVRAM partitioning?
There is an unsupported driver available though, I posted it to the forums a few months ago: http://opensolaris.org/jive/thread.jspa?messageID=260281 The big problem appears to be getting your hands on these cards. Although I have the drivers now my first supplier let me down, and while the second insists they have shipped the cards it's been three weeks now and there's no sign of them. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

The big problem appears to be getting your hands on these cards. Although I have the drivers now my first supplier let me down, and while the second insists they have shipped the cards it's been three weeks now and there's no sign of them. Thanks to Google Shopping I was able to order two of these cards from: http://www.printsavings.com/01390371OP-discount-MICRO+MEMORY-MM5425--512MB-NVRAM-battery.aspx They appear to be in good working order, but unfortunately I am unable to verify the driver. pkgadd -d umem_Sol_Drv_Cust_i386_v01_11.pkg hangs on ## Installing part 1 of 3. on snv_95. I do not have other Solaris versions to experiment with; this is really just a hobby for me.

The term ZIL is somewhat overloaded. I think what you mean here is a separate log device (slog), because intent logs are always present in ZFS. Without a slog, the logs are present in the main pool. There is one log per file system and it allocates blocks in the main pool to form a chain. When a slog is defined, then it can be made up of multiple devices (in which case the writes are striped across the devices) or it can be in the form on a N way mirror - to provide redundancy. With an SSD you can partition the disk to allow usage of a single disk for multiple ZILs Can we do the same thing with an PCIe-based NVRAM card (like http://www.vmetro.com/category4304.html)? I don't think there's a Solaris supported driver for that device. However, any Solaris device, whether a partition or not, will work with ZFS provided it's at least 64MB. It's performance is another matter. Thanks Narayan ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
