software raid

Hard drives are often forgotten as there isn't a huge amount you can do, apart from buy a Western Digital VelociRaptor.

There is one more option though, using two (or more) inexpensive drives and RAID them together to increase the speed dramatically.

This way you can get to high speed nirvana without destroying your budget.

Last time I tried using a Debian 64bit Xen kernel for Dom0 I was unable to get it to work correctly, it continually gave kernel panics when doing any serious disk IO.

I’ve just tried to reproduce that problem on a test machine with a single SATA disk and it seems to be working correctly so I guess that it might be related to using software RAID and LVM

The Ubuntu Live CD installer doesn't support software RAID, and the server and alternate CDs only allow you to do RAID levels 0, 1, and 5.

Raid 10 is the fastest RAID level that also has good redundancy too. So I was disappointed that Ubuntu didn't have it as a option for my new file server.

Linux software RAID 10 is a worthy RAID level with many advantages. RAID 10 is shorthand for RAID1+0, a mirrored striped array.

Linux RAID 10 needs a minimum of two disks, and you don't have to use pairs, but can have odd numbers (Haha!

Unlike many commercial implementations, which are less flexible and more annoying). (Linux)

Kevin Burton’s NEW FeedBlog: "I need to give it a bit more thought but it looks like we’re going forward with deploying Spinn3r on SSD.

Specifically, machines with 3 SSDs on Linux software RAID. The performance of SSDs is nothing short of astounding..."

LXer: "The GNU/Linux operating system is blessed to have sound partition management tools like GParted which are very easy to use.

However, when it comes to the management of 'virtual partitions' known as volumes, things are quite different.

There is Linx Volume Management, or LVM in short, however, it can almost only be used from the command line.

Also, it doesn't integrate software RAID - except for striping. I was quite optimistic when I started using volume management some four years ago, but not anymore.

Let me explain why I'm disappointed."

Linux.com: "Want to get an idea of what speed advantage adding an expensive hardware RAID card to your new server is likely to give you?

You can benchmark the performance difference between running a RAID using the Linux kernel software RAID and a hardware RAID card.

My own tests of the two alternatives yielded some interesting results."

SoftRAID LLC is pleased to announce the release of version 3.6.7 of their RAID software for Mac OS X. With this release, we continue to deliver the best software RAID solution for the Mac.

Using some of the basic Linux command line utilities you can build a software RAID that spans multiple network shares of different types.

Combine this with FUSE and you could have an extremely powerful--and fault tolerant--storage system.
