FreeNAS 8.0.1 Release Candidate 1 [i386+amd64] (2xCD) | 220MB
FreeNAS is based on FreeBSD using Samba and PHP supports software RAID; it can be accessed by protocols CIFS (SMB) Apple Mac AFP FTP SSH iSCSI and NFS. FreeNAS to work you need a computer with the ability to boot from the CD-ROM drive with at least 128 MB of RAM. Distribution has the size of ~ 16Mb. An ISO image distribution has a size of 60 Mb and allows you to deploy as well as work with the system straight from the CD with the ability to install it on your hard drive. Authentication is based on the local database of users. Indicated vozmozhnost authenticate based on an external LDAP directory for example Microsoft Active Directory. FreeNAS server may be included in the domain of Microsoft AD. But as the author points out there is no vozmozhnosti provide access to folders based server for user accounts Microsoft AD. You can connect FreeNAS server to the domain name from Microsoft AD domain account and then under the same user account to work with the server via CIFS (SMB).
FreeNAS can act as an iSCSI-target. It can be connected with the client software iSCSI-initiator. For example Microsoft iSCSI-initiator. This will require the use of a gigabit network to obtain the best performance when transferring data. At 100 Mbps network cards speed data transfer between the server and the iSCSI-target client iSCSI-initiator does not exceed 6-7 MB / sec. Another interesting possibility could be called FreeNAS work via Rsync. In this FreeNAS can act as a server and a client.
