When did you order, Vega?
Dell Order Details page still says that mine will be delivered on Dec. 23rd (coming Monday). But I haven't received a shipping notification yet?!
The SAS2008 controller does not seem to work with ZFSguru 0.1.7p3. I will test with 0.1.8. Just FYI.
Possibly a conflict with my motherboard, IDK at this point...testing...
R-Studio.
It is possible to recover the deleted partition table (i.e. reconstruct it) using Acronis Disk Director. BUT I would advise you to use R-Studio first.
You should be in the clear if you have NOT written any data to the drive since "deleting" the partitions.
If they are as valuable as...
Adding some fuel to the fire...

I have found SpinRite to be totally useless and simply quackery.
After dd I would recommend either R-Studio or GetDataBack.
Acorns has a tool that can rebuild partition tables.
Edit: misspelled Acronis.
But do you need your ZIL to be "that" fast? For a home server?
I think the 320 40GB will be just fine.
Edit:
And add to that, the Intel 320 is based on the proven Intel X25-M controller. I think that is more reliable than an ACard.
The Intel 320 series SSDs have a bank of capacitors and a design with "enhanced power-loss protection".

The Intel 320 SSDs have higher IOPS rating than the 510...
I would direct your question to the Arstechnica Civis Server Room forum.
There are lots of professionals over there who have experience in storage sizing.

Get the QNAP. It will very likely be a very easy setup. IMO, DIY is not the first choice when you are deploying to a production and business environment. Especially when funds permit you to buy a system that is supported.
In the case of DIY,
I would be wary of what software you use to run...
Anand at Anandtech is checking this out.
So in a nutshell (I posted this elsewhere):
How can a NAND chip be graded as full spec when it was initially discarded (by Micron)? An answer is that they were inadvertently discarded. Is this the case? If this is not the case, then they were purposely...
Hello,
Are there any sub $2000 USD tape drive implementations for 20-30TB of storage?
Excluding tapes. Something that can be managed in Windows.
I have read that magnetic tape is more reliable than hard drive storage, so I think I might want to archive the really important data onto tape...
Because OCZ is shady. And others will be releasing Sandforce 2xxx based SSDs. Any performance premiums that OCZ gains from an exclusive partnership, I think, will quickly be mitigated.
Corsair will be releasing a Sandforce 2xxx based SSD, the Corsair Force GT.
It's red though. *shrug*...
Thanks for bringing this to our attention. This remains to be independently verified though (I'm not surprised if this is indeed true).
Perhaps OCZ should issue a response statement.
Does that motherboard fit in the Norco chassis? The motherboard is SWTX.
Edit: Nevermind, read your latest post. Care to post some pictures of the motherboard placement?
It should work fine with dual booting setups.
Don't quote me on this. I think that it is safe to use Truecrypt WDE with a hybrid drive (e.g. Seagate Momentus XT). Any data written to the drive would first be encrypted by CPU and in RAM, then written to the drive. The drive would then buffer to...
I use Truecrypt AES WDE on a Thinkpad X201 Tablet and Intel G2 80GB (i7 something...I forget...it has the AES-NI instructions). It's very fast. I have no noticed any slow-down in comparison with the same drive without encryption.
Kingston makes a SSD that has built in WDE.
What VMs will be running on the hypervisor? Single processor, X3430, 16GB of RAM isn't a lot of hardware. And running a NAS/SAN and VMs on the same machine? With three VMs? I would be hesitant.
Agility 2 L2ARC? Isn't that a bit low end for a cache...and a very small size too.
I wouldn't bother...
Hmm okay...have you tried using COMSTAR iSCSI target? If you get significantly better performance through iSCSI, then we can focus on CIFS and NFS services.
I added a bit to my above post before you posted...don't know if you got the bit about iperf...check that too.
Edit: forget about...
Is the server using CIFS/SMB version 2.0 (or later)? I'm not too familiar with the intricacies of the NFS protocol...but I know significant performance advantages can be gained by the more recent SMB protocol versions.
Receive side scaling (RSS) enabled?
Max Rx/Tx buffers?
NUMA, I/OAT enabled...
SAS2008 is buggy under FreeBSD 8. E3-1230 might not be fast enough.
Update: I should add that I found that the SAS2008 would not boot with my mobo and FreeBSD...this was at least a month back.
IMO, you should definitely put the VMDK files on the SSD...a huge bottleneck for a ESXi server is the...
High speed networking with the vmxnet3 driver and vSwitches still puts a huge hit on the CPU...I was testing between two Win2008 server VMs with vmxnet3; with vmxnet3 drivers transferring at 6-7 gbit/s (iperf), there was 50% CPU consumption (single Xeon E5620). ESX hypervisor was not designed...
Just because it seems possible to virtualize a SAN doesn't mean you should. You're going to max out the CPU and RAM by running just the SAN OS if you have everything running properly.

You will need to check your laptop internals to see if there is a spare mini PCIe slot.
You won't saturate more than 1 gbit/s over four 1 gbit/s links when reading/connecting over client (one IP to one IP), regardless of whatever dladm policy you use. There is no round-robin feature. http://wiki.genunix.org:8080/wiki/index.php/Solaris_Link_Aggregation
You might want to try using...
No need to push ZFS so hard...for just media streaming to a few computers, use a Windows based server.
Perhaps:
Core i3/i5, 4 to 8GB of DDR3, four hard drives, a mITX board with PCI-e, Fractal Design mini-ITX server case (which I think supports six drives). WHS, Windows Server, Unraid...
The external power bricks for the 120W and 150W versions of the picoPSU have tiny 40mm fans inside them...very annoying. The picoPSU itself has no fan of course.
400W PSU is indeed overkill...at 40-50W output the efficiency I think will only be 40-60%.
I have a Supermicro pizza box D525 server...
Any update on SAS2008 compatibility since I last described the timeout issue?
And one other thing...will these features (rtorrent, Virtualbox, etc) be available as packages? So that, if I don't want them, I can not have them installed (in order to save resources, increase security, and so on)?
IMO, bad idea to port forward to WAN.
Tag them on their own VLAN and setup a VPN to access only those IPMI interfaces (perhaps with pfSense, a managed switch, and a opt interface).
Edit:
Some info on securing the IPMI...still, not secure enough IMO...
Yes this panic always occurs:
ZFSguru liveCD emulation with SAS2008 and SAS1068E passthrough: panic
ZFSguru liveCD emulation with SAS2008 passthrough only: panic
ZFSguru liveCD emulation with SAS1068E passthrough only: NO panic
ZFSguru installed (installed without any controllers attached)...
