Hi,
In simple terms, the ARC is divided into a MRU and MFU side.
target size (c) = target MRU size (p) + target MFU size (c-p)
On Solaris, to get from the MRU to the MFU side, the block must be
read at least once in 62.5 milliseconds. For pure read-once workloads,
the data won't to the

Our Dell T610 is and has been working just fine for the last year and

I also ran into the problem of Dell+Broadcom. I fixed it by downgrading
the firmware to version 4.xxx instead of running in version 5.xxx .
You may try that one as well.

Hmmm.. Tried to post this before, but it doesn't appear. I'll try again.
I've been discussing the concept of a reference design for Opensolaris systems

That you did a zfs send does not prevent you from rolling back to a
previous snapshot. Similarly for zfs recv --

You'll need to reboot and go into the card bios to

I am trying to understand how refreservation works with snapshots.
If I have a 100G zfs pool
I have 4 20G volume groups in that pool.
refreservation = 20G on all volume groups.
Now when I want to do a snapshot will this snapshot need 20G + the amount
changed (REFER)? If not I get a out

That would be better than almost any HDD on the planet because
