-All user home directories for the department are now stored on ZFS storage located in the "​003"​ server room in Rice Hall. ZFS is a widely used, industry-standard storage platform that offers modern features such as backups/​snapshots. User data is stored on a Nexsan E-Series storage appliance ​capable of scaling to petabytes ​in a single 42U server rack. The disk arrays ​in this device ​are connected to a SAN (storage area network) via 8Gb fiber-channel and served over NFS by servers ​running Solaris.+All user home directories for the department are now stored on ZFS storage located in the "​003"​ server room in Rice Hall.

-^NFS|CS filesystems are exported via NFS to department-managed ​Unix systems - Linux and Solaris ​interactive and compute nodes. Filesystems are mounted consistently across all nodes so the paths are identical no matter what node you are working on. If you have root on your own desktop or laptop, we do not export NFS to your machine, you'll need to use SMBFS/CIFS.|+^NFS|CS filesystems are exported via NFS to department-managed Linux interactive and compute nodes.

 ^SCP/​SFTP|For truly remote access, we recommend using an SCP/SFTP client: the openssh package available on almost all *nix based systems - Solaris, Mac OS-X and the Linuxes. For Windows platform users, openssh is part of the cygwin packages, and ITS also provides SecureFX at ITS Software Central. For these connections,​ you should use the hostname ''​%%portal.cs.virginia.edu%%''​ to access the files; direct access to all file servers is restricted to Samba and NFS services.| ^SCP/​SFTP|For truly remote access, we recommend using an SCP/SFTP client: the openssh package available on almost all *nix based systems - Solaris, Mac OS-X and the Linuxes.
