Is there a card for OpenSolaris 2009.06 SPARC that will do SATA correctly yet? Need it for a super cheapie, low expectations, SunBlade 100 filer, so I think it has to be notched for 5v PCI slot, iirc. I''m OK with slow -- main goals here are power saving (sleep all 4 disks) and 1TB+ space. Oh, and I hate to be an old head, but I don''t want a peecee. They still scare me :) Thinking root pool on 16GB ssd, perhaps, so the thing can spin down the main pool and idle *really* cheaply.. thx jake -- This message posted from opensolaris.org

I have one in my V880. On a Blade-100, however, you might have some issues due to the craptitude of the PCI slots. To be honest, the Grover was a fun machine at the time, but I think that time may have passed. Oh, and if you do grab the LSI card, don''t let James catch you using the itmpt driver or lsiutils ;-) -- Andre van Eyssen. mail: andre at purplecow.org jabber: andre at interact.purplecow.org purplecow.org: UNIX for the masses www2.purplecow.org purplecow.org: PCOWpix pix.purplecow.org

In my experience there is some severe problems: 1) Once the disks spin down due to idleness it can become impossible to reactivate them without doing a full reboot (i.e. hot plugging won''t help) 2) disks that were attached once leave a stale /dev/dsk entry behind that takes full 7 seconds to stat() with kernel running at 100%. Apart from that it works fine. - Thomas

If they don''t, it''s a bug IMHO. Regards -- Volker -- ------------------------------------------------------------------------ Volker A.

If there was a good way to mark certain devices or a device tree as "volatile" then this would be an interesting RFE. I would certainly not want *all* of my disks to "come and go as they please". :-) I am not sure how feasible an implementation would be though.

Or to be more precise I have a small chassis with two disks, which I only want to attach for backup purposes. I just send/receive from my active pool to the backup pool, and then detach the backup pool. I just like having backup disks being physically detached when not in use. Like this, nothing can really screw them up but a fire in the room... I thought SAS/SATA would be hot-pluggable - so what''s the difference between USB''s hot-plug feature and the one of SAS/SATA other that that USB is handled by the volume manager? So, yes, it would be nice if one could assign a SATA disk to the volume manager. - Thomas
