Re: ZFS and Storage Systems

2010-10-12 Thread Michal




 It would be even better to simply ask them what exact Supermicro
 hardware (specifically, model numbers) they're using to build these
 systems.  You can see Supermicro mentioned in the   of their site,
 so that's definitely what they're using, even down to the controller
 card offerings (some of which (Marvell) are known to behave oddly on
 FreeBSD (yes there are success stories, but there are also follow-up
 horror stories) -- consider yourself warned).


I think the best option is to just build it your self using similar
components which I have looked at before. My ideal is build a system
where you can extend the storage easily by adding another box instead of
either replacing the HDD's with bigger HDD's or having multiple targets
for the data. One target whose storage can be expanded by simply adding
another box. However, that is harder in practice to work out

It's interesting that the vendor (ICC) advertises this as a 12-disk box,
yet it's only an 8-disk chassis.  Additionally, the PSUs are 720W, not
800W, so I'm not sure why they claim that either.

The chassis in question is almost certainly a Supermicro SC825TQ-R720UB,
by the way:

http://www.supermicro.com/products/chassis/2U/825/SC825TQ-R720U.cfm

The picture doesn't show the front bezel serial/USB ports mounted, but
they're visible on the SuperServer 6026T-URF (which is probably what ICC
is selling anyway, pre-populated with CPUs, RAM, etc.):

To me these look like "storage servers", i.e. standard server
hardware with room for a lot of hot pluggable drives. This point
in their description seems to confirm that:

+ DSS Lite 

That's a Linux based commercial NAS system that you install or
plug into standard servers to turn them into a NAS.

See http://www.open-e.com/

So, IMHO, yes, you should be able to replace that DSS stuff with
either stock FreeBSD or preferrably FreeNAS to turn one of these
boxes into a ZFS based NAS. I'll check with the supplier before
ordering, nonetheless.

You say "using a FreeBSD box I can set up ZFS over the drives...", which
doesn't make sense, if I undestand the ICC system. The device appears to
be an NAS system, with an OS, not an external disk bay.

What you would want, I think, is either a) an external FCAL or iSCSI box
that you could connect to another machine (running FreeBSD or some other
OS); or b) a 'storage' server upon which to install FreeBSD and use as
a NAS system.

It may be that the ICC system can export the drives, but it seems like an
unnecessary complication.

ZFS and Storage Systems

2010-10-12 Thread Michal

 Morning,

Apologies for the basic question but I just want to make sure. I have 
been looking at storage systems like this one 
http://www.icc-usa.com/storage-35-2u.asp. I am guessing it would be a 
case of sorting the discs out, probably on some GUI or command line for 
the box it self, then using a FreeBSD box I can set up ZFS over the 
drives...or is it not that simple?


Thanks
Chris
