Anyone use one of these hot swap SATA rack mount devices?
on Jan 25, 2007 at 3:54:10 pm

http://www.granitedigital.com/catalog/pg61_alumhotswap2-4-8rack.htm ...'m looking for an easy solution to backup massive projects to SATA drives for archive without having to screw hard disk drives in and out of enclosures. I found this device, but I am skeptical about it not having a fan. Might not matter for a temporary backup use, but I've already sworn off Lacie drives because of their heat issues. If this thing works as advertised, I would get a simple host card for each of the two G5's in my machine room, and run a SATA cable from each to one of their 2-port models. We are doing everything P2 now, so we have the need to keep the MXF files and the QT file separate, and then archive the MXF files to SATA drives along with other project data. Tape systems seem too slow and costly. Also, would there be any performance hit by having an additional PCI card on the bus along with the K2 and Fibre cards to XServe RAID? My main concern is that the pdf describes the possibility that some computers will require a full shutdown to swap out a drive, which would be a pain for me. Anyone look into this or a similar device? steve covello doublewide post

Does it have to be a rack mounted solution? I use the Firmtek four bay enclosure which has plenty of cooling capacity. Granite makes boxes with fans too.

By the way there was a post last week about hard drives not being a good medium for archiving. I don't recall the poster using any kind of citation, just that they had read it somewhere. Just thought I'd mention it so you can check it out. I have no information as to the accuracy of the statement.

Hi Steve -
I did not look at the Granite Digital chassis. If you use a Cal Digit or Sonnet Fusion chassis, these products can be use not only for backup, but for actual work. A single Cal Digit S2VR chassis will give you identical performance to your expensive Xserve RAID. There is ABSOLULTELY no problem in running all 3 cards (Kona, SATA host, and Apple FC card) in the same G5. It works just fine. All the SATA guys have rack mounted solutions that are either out now, or about to come out. But a simple small 5 bay port multipler SATA box will handle all of your back up needs - or drives for REAL performance (not just backup).

I'm using one of these: http://www.pc-pitstop.com/sata_enclosures/scsat84x.asp
$409, with fans out the wazoo! 3 fans for the chassis, plus one fan on each tray. They also sell 10 & 12 drive enclosures, and enclosures and these enclosures are available with eSATA connectors.

I've been using one of these:

http://www.newegg.com/Product/Product.asp?Item=N82E16812104062

with bare drives for temporary backup. $69 for a 250 Gig drive plus $25 for this little adapter makes it easy to backup to hard drives and there are definitely no screws involved. But I don't really trust hard drives for permanent archive purposes. Up to this point I've archived everything to DVDs, but with more HD and P2 I am going to have to find a better solution. For me hard drives are not the answer, but I have had success using the above device to move stuff back and forth easily between drives and as a P2 backup device on location, tied to a laptop.

Now all I need is an inexpensive, padded storage case for these bare drives. Any takers?

Oh man, if you find something, please please let me know. I back up all AE renders, project related stuff, DVDs, self contained of finished timeline, raw p2 mxf files to SATA with one of these:

I would love a convenient to store/carry these things. Try searching for hard disk storage on google, and it doesn't really work out.

Thanks for the suggestions. What's curious to me is that HDDs have been around and have been improving year after year, yet some of you prefer to backup to optical disk, which has not proven itself AT ALL as an archival medium. If an optical disk goes bad, forget it. No recovery service will salvage a warped or stained reflective layer [as far as I know]. Whereas, there is an an entire industry dedicated to resurrecting HDDs no matter what happens to them short of evaporation. Seems like with proper care and consciousness of static electricity damage, archiving to HDD could be as reliable [or unreliable] as anything else. We're not talking about swapping drives in and out like cassette tapes on a cross-country road trip. Any evidence to the contrary? steve covello double wide post

I have definitely created more DVD-R coasters in my time than I have seen hard drives completely die. Since these SATA drives are just sitting around and not being spun around and written to at all times, I feel comfortable with them in the long run. Also, when I have seen single hard drives go bad (such as external firewire drives) die, it's usually the bridge chip or host controller that goes first. If you pull out the disk and plug it into another enclosure, it works like a charm. None of this applies to any drive in a RAID or RAID set as that's a totally different application and use.

I have only been doing this backup method for about six months so it remains to be seen what the longevity will be. When someone calls and needs a title change or one more copy of the final DVD, there's is no easier way to restore a project , or burn a DVD than off of a SATA drive. If the change is easy enough, I will make change right off the the backup drive instead of dragging it all back to my edit system. It's a lovely method. I use a cataloging software called (off all things) DiskCatalogMaker http://hp.vector.co.jp/authors/VA008942/library/diskcatalogmaker/ This is the icing on the cake. This simple software creates a database that is searchable. As of now, I have 9 SATA disks in my archive (labeled disk1, disk2, etc.) When I make a backup, I have the DiskCatalogMaker scan the disk and make a record of the contents. That way, I can search for projects without even plugging in a disk. It is extremely efficient and useful. I was looking into a DLT system, but it was pricey, seemed like a slow process, and I couldn't find anyone to sell one to me.

Very cool Jeremy, and $19 for a single user license! Thanks for the information.

I've been using CD Finder for the same purpose. Hugely happy:

Have you looked into SDLT. It is currently the only tape format that is being tailored specifically to the pro video market. It has a file system on the cartridge and is quite fast. Gigabit ethernet and built-in FTP. They will have 800gig cartridges out by NAB and they have a 30 year archival life. You can buy directly from Quantum as well.

Jeremy,

I recently completed a test of the Quantum SDLT 600A drive a few months ago. After careful consideration of this drive's effectiveness, I choose to return the demo unit to Quantum. Until the price drops significantly on this DLT drive, I will not become an owner. The DLT hardware met my expectations, however, the bundled software (including FTP server) was inadequate.

Based on your posted comments, I suspect this drive is likely out of your price range. It sells for more than $6000 USD. However, If you do decide to demo/purchase this system, Imagine Products (http://www.imagineproducts.com) is a reseller. Best of luck...

We use the Aluminum 4-bay (fanless) chassis under a RAID 5 with no worries. The enclosure gets warm - hot but Granite Digital says that is what provs the heat sink is working and that the temps are far below the operating threshold of the drive specs. With that said though, they're designed for studios where fan noise is a problem.

We also employ their SATAVue

I'm using a HotPoint card here. It's been fairly reliable, but if the Atto had been available back in October/November when I came back from location, I would have spent the extra. My experience is that the Hotpoint want's to be unmounted & powered down before you shut down the mac, or it may remount with a drive missing.
