Is there a storage device that can push 500GB in 11 minutes?

That's around 758MB/s!

Does anyone know of a storage device that push this?

Some big bank CIO claimed his disk-to-disk backup solution can do 500GB in 11 minutes and compress + encrypt data at the same time.

I call shens, but he insists that his shop runs this.

Unless it's a SCSI RAID array... nah, even then I haven't seen anything that can push >750MB/s sustained... that's in the speed range of older RAM!

Maybe he meant 500Gigabits in 11 minutes? That might be doable

Sure, there are many solid state storage solutions that can do that. Depends how much you want to spend on the device. If it is a business and the device is mission critical where cost is not an option.

http://www.dynamicsolutions.com/disk_sys_ssd.asp. They offer a 400 mb/sec model and a 3 gb/sec model. There are many more options but DSI is usually one of the cheapest. These devices are also made to be daisy chained, for extremely high performance. 16 of these in a 64u for 2 TB of disk, costs around $1 million USD. Hooked up by 8x4 GB/SEC fiber chnanel ports and you have yourself a pretty good SAN for mission critical applications.

Also calling SUN to get a quote for their equivalent. They are going to offer you a 64u with 128*73GB 15,000 RPM drives. Will still use Fibre Channel and you will be forced into using Solaris. You do end up with a nice Quad Dual Core AMD Box though with it. At a certain point you are talking about millions upon millions of dollars in infratstructure. A buddy of mine works for a large datacenter of a fortun 500 company. They have 20,000-30,000 VPN users at a time in a given day. In a given month they spend around !$1 million in bandwidth (4x 2 Gigabit redundant lines), and another $1-2 million in infrastructure upgrades. I believe all of this stuff is over what you needing, but in case you get that sweet hardware ordering job in the future, we can all dream.

You don't even need the fancy SSDs. You can get that kind of performance out of high-end SAN setups -- in a system like this, you're copying from disk->ram->disk. Encryption/compression would be done by dedicated hardware.

Conceptually, think of doing something like a RAID0 but with the data spread over 20+ drives on each end. If you get even ~50MBps sustained from each drive doing sequential read/write, you could easily copy 1000+MBps like that in a storage system with enough memory bandwidth (assuming nothing else is going on with those drives).

Hell, you can even do it with remote replication if you want to pay for enough single-mode fiber links...

Here, simple solution for about 4000 dollars.

Get 24 7200.10 Seatgate 320GB hard drives for 2400 bucks
Get an Areca ARC-1280,, Put all the drives in a RAID 6 (for redundancy during backup)

You can get sustained transfers of 811 MB/S read and 776 Write or more.

Sure this is right on the edge, but with the right server and OS it will work as specified.

wow, that's a pretty good solution...thanks for the heads up!

Do you know if this card supports hot plug?

edit: um, one problem...where do I find a 24 drive bay server base that can house this beast?
