Xiotech ISE
I believe vibration is one of the things that Xiotech has tried address with their ISE bricks.

I don't work for Xiotech. I just think it's a cool idea.

Re:Dont worry too much
Actually, yes. Or at least that's one of the way my SAN vendor is dealing with increasing drive size. They are the first vendor to enable ANSI T10-DIF end to end checksumming which includes additional bits per block (AFAIR it's the same as mainframe drives have been using all along). They have also made the recoverable element the surface rather than the drive so recovery times are several times faster. Check them out.

Xiotech is doing it
Check out the Emprise 7000. Scales from 1 TB to 1 PB
If you unracked it, you could squeeze it all into a single Volkswagon, yielding 100 Loc/VW (Libraries of Congress per Volkswagon).

Re:UnclarityWhat is SAN?
What does it do?
How is it disruptive?
Who does it disrupt?
What does it store? http://en.wikipedia.org/wiki/Storage_area_network
It's remote storage.
Their new tech saves you the trouble of swapping HDs.
It disrupts the people offering maintanence contracts.
It stores whatever you want.

Let "Real Life Mom" educate your boss
Thanks to XIOTech, we now have a "real life mom" to explain the complexities of data storage, server clustering and more! You should have your boss watch this series of videos.
warning: videos may result in ROTFL -
Don't fool around with homegrown
Don't do your own. It can be disasterous. XIOtech is awesome.

Re:Linux, Fibre Channel, and SANs - popular linksThere's a lot of good points here; Linux has Fibre Channel Arbitrated Loop (FCAL) support via the ISP2100 Qlogic chipset and the 2.2 kernel, but that doesn't constitute a SAN. A Veritas-style transactional filesystem and volume manager are definitely required fundamental pieces for conventional SANs; they allow you to utilize multiple disk i/o queues and spindles to maximize your i/o throughput. Clustering filesystems like GFS are also an important step necessary to work towards developing a single-system image, allowing multiple machines to work together with a uniform set of available and shared resources. As such SANs are the enabling technology for true clustering. Clustering with shared resources, global process ID's, and process migration between systems are the ultimate in flexibility as processes don't require modification to take advantage of clustering capabilities; this is much more powerful than simple shared-nothing Beowulf clusters.
We are currently running several Solaris systems with a 3rd-party FCAL SAN-in-a-box from XIOtech. We have a second one serving our Netware servers. If you're serious about getting the benefits promised by SANs today, I'd recommend checking them out. They allow you to create virtual disks in various RAID configurations, move the virtual drives between different virtual clusters, and copy and swap virtual drives on the fly.
