People and their problems huh? I wish I could "only" get 20-30Mbps. :( @OP Yes, you will be throttled. That's just the nature of the business. They let you burst, but ultimately throttle you.

Depending on the usage, I would. :) There are lots of read heavy deployments out there. In many cases, data is literally written once, never deleted, and then read often. Well, let's get some benchmark before assuming they have achieved practical performance not possible with consumer...

@OP Let's recap: 1. SSD RAID 0 failed 2. Internal backup disk corrupted 3. Network backup was never kept up and outdated What failed for you is not the RAID 0 array. What failed is your backup strategy. Make sure to remember and understand this key point for your next setup. There...

Wait... so, you were given approval to lose all the data on the array? Must have not been important data to choose to lose it over merely $1k in expenses.

Why are you being so cheap? :p Just buy 6x 4TB disks and start saving the disk images.You can then resell those bought disks to recoup some of the cost after all is done. You are ignoring all advice asking you to do so without providing any real explanation as to why you won't/can't. Moreover...

No matter what happens stick with it and copy the data out. It is only after that you should move the disks to PC and boot from a Linux CD to inspect. They may be using mdadm, but you don't know which version and what custom things they might have done. The point of running a Live CD after...

FYI, lot of new features were added to tRAID including Storage Acceleration, which was the last planned feature. This essentially resolves the last aspect of performance concerns associate with the approach.

If your current box is maxed out, then you have no other option than to build another box. If your concerns are on having a single point of access to that data, remember that RAID-F and RAID and pool network shares. Don't over tax a single system. Too many disks under a single array is not a...

Screw the equipment. Another gun now in the streets. :rolleyes:

Except that it is typically in an incredibly noisy electrical environment with no decent transformer to deal with that unlike in an good receiver. Any amplification in such an environment comes with a free doze of noise amplification (especially for headphones). Everyone knows well to...

No idea. I don't know much about fixing PSUs. So, they were all simply trashed. I wish I could fix these things. Not so much to save money, but to be able to better troubleshoot these things. I ended up ordering a new motherboard and CPU in addition to the power supply as I was not sure...

Having gone through another PSU failure, making it the 3rd in the last six years, I am now pondering whether PSUs have a general short lifespan or whether it is purely my environment that is killing them. I have been a fan of Fortron Blue PSUs and bought five of them. three have now died...

@skypine27 Indeed the Raptor has the edge, but I understood that you wanted a compromise between speed and space, which the Barracuda fulfill. You might get disappointed in waiting for high RPM larger drives. HDD manufacturers are struggling making them. In fact, Seagate has not put out yet a...

+1 The only drive that I am now buying outside of the Intel G2 SSDs.

Yes. The Samsung Barracuda 3TB 7200 perform equal to the 1TB V-Raptor: http://forum.flexraid.com/index.php/topic,3111.msg21125.html#msg21125

The Dell C1100s are the absolute best bang for the bucks and have been so for the past year or so. I mean, the 72GB or RAM alone is worth the entire price you pay for them on ebay. You can even upgrade the CPUs to the 56xx for a 12 cores system. Maybe I lucked out, but mine is very quiet (or...

Hum... thicker bezel though. The rumor pics look much better.

@Valnar Obviously, if you need to store things mid-term, you certainly need to hunt down older SSDs. I am personally a fan of the Intel 160GB G2 series. I bought a bunch for my ESXi boxes. I traded performance for reliability. That said, I plan on buying a few Evo pro to host my software build...

Simple. Ever since higher clocked multi-core systems became popular, the need for multiple sockets is fading as it should. A system with multiple sockets isn't a feature but rather a workaround a limitation (that of not being able to put more cores on a socket). With time, that limitation is...

Or, you could just setup two 3TB as PPUs and leave the rest as single DRUs except for one which you will span a 2TB with the 1TB you have. However, if you plan on buying solely 4TB disks going forward, your last option does make sense.

This is why many users choose to build their own NAS using either old PC parts or cheap parts. You can get a lot more out of a PC based NAS including better expandability.

I second that this is bad. The company might have put out a lot of bad products and I never bought any of them, but they did a lot for the tech space. OCZ is mainly a marketing company, but they did influence the manufacturers that sourced them along with pricing in the general market.

Once again, there is little purpose to a hot spare in RAID 1 unless your controller limits you to 2-way mirrors.

I really don't see the issue here. Let him have it. Just make him purchases more drives for DR. Remind him how if the volume gets corrupted or files are inadvertently deleted, it is all disks that are affected. A 4-way mirror + a good backup strategy has no negative. :)

It all depends on how much capacity if wants to be left with. If only the capacity of a single drive, then either a 4-way mirror or a duplex-ed mirror (mirror of a mirror) will give him that 25% capacity and higher protection level. If 50%, then two mirror set will do (although a poor choice vs...

Your data is going to be at risk each time you do this expansion. Between the time each expansion would take and the risk involved, I would say this is a bad idea. You will play with Murphy's law each time. Wait to get all the new drives and a new controller to do the migration. That or backup...

Scary thread. Not enough facts and too many assumptions. :) Not all database implementations scale the same. Some scale better horizontally and other better vertically. There typically is a cost on I/O when you virtualize, but the hope is that you make up for that by better horizontal scaling...

+1 LOL!

1.On the noise front, I am not opposed to modding. However, reading the thread in the other forum, it seems that even then we are still looking at 50db+ and a system that still needs to be in a garage. 2. On the powering side, cool that individual nodes can be powered on/off through IPMI. We...

I have been drooling on the c6100 myself, but I am passing for now due to: - the noise - additional power usage - the fact that you can't power on/off the individual nodes separately - PSU not redundant even when you have dual PSUs It is an awesome product though for those of us wanting...

NZFS TRAID is now in UAT (User Acceptance Testing). It should finalize in the next few weeks.

The full stack will be out in a few months. However, the Transparent RAID feature will be out next month.

It just keeps on getting better: http://www.openegg.org/2013/03/08/a-pretty-cool-nzfs-raid-feature-why-run-in-degraded-mode/ :)

Some goodies being added: http://www.openegg.org/2013/02/28/a-freebie-for-nzfs-users-forensic-drive-erase/

Not out yet, but keep an eye on: http://www.openegg.org/2013/02/28/a-freebie-for-nzfs-users-forensic-drive-erase/

nevermind...

Please don't discount write amplification. For writes under 512KB, going RAID-0 will increase wear while performing worst. So, make sure your RAID-0 stripe size matches the erase block size.

I think the thing to realize is that SSDs RAID-0 internally already. So in theory, 2x 128GB will be slower than 1x 256GB since the RAID-0 in the larger drive is internal (greater bandwidth + lower latency) vs external.

:confused: /I give up...

Of course not. The degree and e-penis war is entertaining, and I am guilty for enjoying a little bit of drama. :D If you follow the thread, you will find my statement about me saying nothing yet of the the file system aspect of NZFS. Basically, you are criticizing on empty. ;) Now, there...
