Having tried several NAS systems I was looking for something with not to much overkill to install on my VMware ESXi server and found Rockstor. I will only need it for sharing NFS and SFTP, so perhaps a little overkill But I have to admit, I might be going to use it for more. I like the way you can add disks, shrink and resize your pools, really great tool I hope it will grow to a great but mostly very stable system.
@suman I want to use it at home, all we run is Linux Debian we have only a virtualised windows left, but would be glad if the last programs are replaced so we can purge windows… The free esxi server is a great help, we run Virtualbox on the desktop. But I prefer esxi for some situations.
