[rescue] Solaris 10 nvdisk/Micro Memory driver/ZIL ideas?

[vivianne at chinstrap.org]

In my home setup, I have a Solaris 10 1/13 NIS master which is also serving home directories and some other stuff over NFS from a mirrored pool. NFS performance for writing lots of small files is absolutely terrible with ZFS sync enabled, as you'd expect with an integrated ZIL. For example, extracting a tarball of the GCC 4.7.4 sources takes ~33 minutes with sync on standard, and 3 minutes with sync disabled. I'm not too concerned about the data here obviously, so if I have to, I'll give in and just live with sync disabled, but I think it'd be fun (& nice) to have a proper ZIL device to alleviate this issue without disabling the ZIL/sync.

The actual physical server is a Sun Fire V210, the pool is two mirrored 73.6 GB U160 disks, and there's a free PCI-X slot. Anyone have ideas for a log device?

I found this: https://www.oracle.com/webfolder/technetwork/hcl/data/components/details/micro_memory/sol_9_12_02/259.html but I don't see the driver archived anywhere. Anyone have it? It seems like a good candidate.

Thanks,
