You still got these?  I'm in Austin and interested.  I can have a buddy 
in Dallas grab them from you and then pick them up from him later if 
that's OK.

Sorry about previous, I forgot this list is set up reply-to-list.

ZFS + PostgreSQL


Greetings,

I'm trying to find a way out of for my PostgreSQL RHEL Server. I was
wondering if anyone has done some benchmarking using PostgreSQL on a
ZFS volume/pool. Granted it would be better for scalability in terms
of storage + mirroring, but I don't wanna pay a high price on performance.

Thanks in advance.
Javier

This would likely be of interest...

V240 RAID

Hello,

I'm trying to put together a server with RAID5 and 200GB of disk. Does
anyone know if V240 can do RAID5? Are there any other (not very
expensive) models that can do it? Is it better to get something older +
RAID adapter?
Thanks for any suggestions.

Mike

Re: V240 RAID

Hey Mike,

V240 only has two internal disks.  You need atleast three disks to configure
Raid5. Unless you have external storage (3310 JBOD) attached and use SVM.

Either stripe with no redundancy, or use standard mirroring.

V440 is capable of Raid5 configuring. Or, have a look at the Ultra45.

Regards,

Monique

Re: V240 RAID

Thanks Monique. It says on the specs that V240 has 4 drives, however
I've never used one, only V210 from the V2xy series.

V440 is nice, but I'm afraid it is a bit too expensive. I'll have a
look at Ultra45. There is no external storage, so 200GB needs to fit on
internal drives.

Re: V240 RAID

Mike,
 You can't configure RAID 5 using the boot disks, only RAID 1.

So if you have a V240, 2 disks should be a RAID 1 to support the OS, and you
have 2 left. You can use RAID 1 as well, but the biggest size is of a disk
is 146 GB.

You can use a V240 connected to an old D1000, and using SVM you can
configure your RAID5. Don't forget to buy the SCSI Differential HBA.

V240 + SCSI Differencial HBA PCI + D1000 + SVM

The Ultra 450 is quite old and there are many versions. The basic version
only contains 4 slots for disks.
You have to buy the expansion controllers, so is the same as your V240.

Why don't you try with a V880? they always came with 6 disks.

Regards,
Daniel Nuno

Would the server have to be SPARC based?

Whatever solution you opt for you'll need at least 3 drives for RAID5.  A system with 4 x 73Gb drives would
*theoretically* give you approx 219Gb in a RAID5 config

A single CPU V240 with 4 x 73Gb disks will cost approx 2,380 GBP,
whereas a single CPU X4200 with 4 x 73Gb disks will cost approx 2,560 GBP (these are list prices from uk.sun.com).

146Gb disks are available for both, though obviously the cost will be greater.

Either way, you're looking at using SVM for the RAID5 config as I don't think either system does hardware RAID5.

If you're simply wanting to get experience of RAID5 and aren't *too* bothered about performance there are
probably some
older systems available on the internet, though depending on the age of the system you may be looking at 36Gb
disks so
you'd want 7 or 8 of those in a desktop multipack or similar.
