We love ZFS because it can bypass a lot of the issues that might arise when using traditional RAID cards.

We’re going to talk about some of the features that make ZFS unique and then give you an example from one of our customers who saved a lot of money because he was using ZFS with software RAID. Now we’re going to dig into one of our favorite file systems and volume managers, ZFS. It’s clear that computers and software have come a really long way and it’s becoming clearer that software-defined RAID is going to be more and more prevalent as time goes by. After that the steps are simple, just plug the drives in and get to work – you should be able to recover from just about any situation where your data loss hasn’t exceeded fundamental limits. To recover your data, all you need is another storage server with the same OS.

It’s also much more capable and powerful in recovery situations than hardware RAID. On the software side, today’s software RAID is super-fast (at least with Linux and BSD), extremely flexible, and highly integrated into OS’s. However, it continues to have a data security risk because you need to use an identical (or compatible) controller to recover data in the event of hardware failure.

This is particularly useful with MS Windows which has a painfully slow implementation of software RAID. Hardware RAID continues to offer solid and simple architectural solutions for combining multiple drives into RAID arrays and presenting them to the OS as a single device. Secondly, the strength, features, and integration of RAID Software have grown dramatically. Computing power grew so radically that the computing load presented by RAID is no longer significant. Two things happened that benefited Software RAID over hardware RAID and allowed it to take the lead. This integration is really what has allowed Software RAID to dramatically outpace hardware RAID. However this also fundamentally precludes integration of features into the OS and file system. This architecture is elegant in its simplicity.

Hardware RAID has the ability to take a group of drives and make it appear as a single drive.

You can’t plug in your set of hard drives into any RAID card and expect it to read your data.

Proprietary/nonstandard protocols mean your array only works with the same hardware raid card.

Challenges recovering data when major failures happen.

Hardware RAID is still popular with some people and many of today’s hardware RAID cards offer kick-ass performance while lightening the load on the CPU, but there’s still some serious problems and disadvantage: This made things run smoothly while benefiting from the security of RAID. It would present itself to the computer’s OS as a single disk, and internally it would process data moving in and out of the multiple storage devices (hard drives). Back then, the solution was to use a hardware RAID card with a built-in processor that handled the RAID calculations ‘offline’.

Hardware RAID does have a place under certain OS’s, but I’m going to tell you why Software is generally far superior.įavoring hardware RAID over software RAID comes from a time when hardware was just not powerful enough to handle Software RAID processing, along with all the other tasks that it was being used for.

In my opinion is that, for most applications, Software RAID is far better than hardware RAID. A question often asked in the server industry is, ‘what’s better – software RAID or hardware RAID?’ If you research this topic, a lot of the information about RAID suggests that a hardware RAID card is preferable to using a Software RAID.
