USB Enclosure?


I have a server running fedora 8, its internal drive bays are full and I would like to add additional storage. I have 2 250GIG IDE drives sitting around and was wondering if anyone could recommend a USB enclosure that holds 2 drives and in compatible with linux? Also I need something that can run 24x7 because this is a server.

I checked the HCL, but its hard to find answers unless you know a specific model.

Thanks

You really shouldn't use two external drives over USB on a server. USB has limited bandwidth, and when using two storage devices your transfer rate is going to suffer. External drives generally run hotter as well, unless you get an enclosure that is specifically designed with cooling in mind.

Hi,

You should look into NAS. FreeNAS is a good one to look at.

USB through put will not meet the needs of even a simple server. If your loads are low then the activity between the usb device and server will still be slow.

Depending on the network and loads a NAS will work.

If you have room in the server case you can add a drive cage:

I have something similar to this (above) just sitting on the floor of my case. Just make sure to handle your airflow properly.

Rather than add a nas, I would add another server. By the time you get a good nas up and running, you are getting close to the same money as a server. Having an additional server also buys peace of mind in that you have hardware on hand(to get you through) in case of a dead server.

The third way out is just to buy bigger drives. 500GB drives are down to $100 (newegg). Swapping out 2-250gb for 2-500gb, buys you 500gb of room plus the drives will probably be faster than the 250's that they are replacing.

Thanks everybody for your information.

This FreeNAS, is it an actual OS? Does it run on top of Linux?

Im confused by the website, can someone give me a basic idea of how it works?

You should look at the Network-Attached Storage. FreeNAS is based on FreeBSD.
