Hi Tom,
My input:
Create one file system per type of data to:
1. help organise your data logically
2. increase file system granularity which allows different file system
properties to be set per filesystem: such as copies, compression etc
3. allow separate shares to be easily setup: via CIFS (SMB
I ran smbios and for the memory-related section I saw the following:
IDSIZE TYPE
6415 SMB_TYPE_MEMARRAY (physical memory array)
Location: 3 (system board or motherboard)
Use: 3 (system memory)
ECC: 3 (none)
Number of Slots/Sockets: 4

Thanks. Newegg shows quite a good customer rating for that drive: 70% rated it

Seems like some people have complained about them sleeping - presumable to save

Yes, this model looks to be interesting.

And did I understand you correctly when you say that these LSI 1068/1078
drivers write labels to drives, meaning you can't move drives from an LSI
controlled array to another arbitrary array
Miles, thanks for helping clear up the confusion surrounding this subject!
My decision is now as above: for my existing NAS to leave the pool as-is, and
seek a 2+ SATA port card for the 2-drive mirror for 2 x 30GB SATA boot SSDs
that I want to add.
For the next NAS build later on this summer, I
> I think the confusion is because the 1068 can do "hardware" RAID, it
can and does write its own labels, as well as reserve space for replacements
of disks with slightly different sizes. But that is only one mode of
operation.
So, it sounds like if I use a 1068-based device, and I *don't* want i
That sounds even better :)
So what's the procedure to create a zpool using the 1068?
Also, any special 'tricks /tips' / commands required for using a 1068-based
SAS/SATA device?

Hi,
Does anyone know of a reliable 2 or 4 port SATA card with a solid driver, that
plugs into a PCIe slot, so that I can benefit from the high read speeds
available from adding a couple of SSDs to form my ZFS root/boot pool?
(Each SSD is capable of reading at around 150-200 MBytes/sec)
After i
I was using OpenSolaris 2009.06 on an IDE drive, and decided to reinstall onto
a mirror (smaller SSDs).
My data pool was a separate pool and before reinstalling onto the new SSDs I
exported the data pool.
After rebooting and installing OpenSolaris 2009.06 onto the first SSD I tried
to import m
Some more info that might help:
I have the old IDE boot drive which I can reconnect if I get no help with this
problem. I just hope it will allow me to import the data pool, as this is not
guaranteed.
Way back, I was using SXCE and the pool was upgraded to the latest ZFS version
at the time.
