Thanks pk.
You know I
Thanks Trond.
I am aware of this, but to be honest I will not be upgrading very often (my
current WHS setup has lasted 5 years without a single change!) and certainly
not to each iteration of TB size increase, so by the time I do upgrade, say in
the next 5 years PCIe will have probably been rep

Beware that this controller does not support drives larger than 2TB.

Only PCIe 1.0? What chipset is that based on? Might be worthwhile to

Thanks.
I ruled out the SAS2008 controller as my motherboard is only PCIe 1.0 so would
not have been able to make the most of the difference in increased bandwidth.
I can't see myself upgrading every few months (my current WHZ build has lasted
over 4 years without a single change) so by the tim
The LSI2008 chipset is supported and works very well.
I would actually use 2 vdevs; 8 disks in each. And I would configure each vdev
as raidz2. Maybe use one hot spare.
And I also have personal, subjective reasons: I like to use the number of 8 in
computers. 7 is an ugly number. Everything is b
OK, I have finally settled on hardware;
2x LSI SAS3081E-R controllers

I am still undecided as to how to group the disks. I have read elsewhere that
raid-z1 is best suited with either 3 or 5 disks and raid-z2 is better suited
Sorry to pester, but is anyone able to say if the Marvell 9480 chip is now
supported in Solaris?
The article I read saying it wasn't supported was dated May 2010 so over a year
ago.

Thanks for all the replies.
I have a pretty good idea how the disk enclosure assigns slot locations so
should be OK.
One last thing - I see thet Supermicro has just released a newer version of the
card I mentioned in the first post that supports SATA 6Gbps. From what I can
see it uses the Marv
