Building a Poor Man's Drobo?

Hi,

I was looking at the DROBO and admiring it's features ... then looking at it's price tag.....   It occured to me - there must be a Linux based product out there for free that can do what drobo does?  I am mainly concerned with data saftey (raid5) and expandability (offline or hotwswap out smallest drive for larger, even it takes a little time)

Between FreeNas and OpenFiler it LOOKS like OpenFiler can sorta do what i am after - but I thought I should check with the experts!!

Thanks in advance

I would give openfiler a try before paying for Drobo. I worked in a company where we had openfiler for this kind of storage.

I think you might wana take a look at this

Who the hell would pay $500 for a Drobo ?

And as you propably know

Openfiler is a Network Attached Storage (NAS) project that couples with CentOS to provide NAS services such as NFS, SMB, WebDAV, and FTP. It can be managed from a simple web-based management utility.

Openfiler can integrate with existing directory service authentication services, such as NIS, LDAP, and Active Directory, and Kerberos.

It can run on Ext3, JFS, or XFS filesystems, with the web management allowing the user to configure the partitions for redundancy, speed or high availability.

If your going to be using RAID5 and your REALLY concerned bout data safety.. then you should at least have a nice hardware raid controller in your computer ( with some RAM and a battery, so your data won't be corrupt in case it's writing to disk during a power failure.. even if your have a UPS )

both freenas and openfilter look good.. from the screenshots! :o
