Network Attached Storage Systems (NAS) understand files and metadata and SAN storage systems only understand block data, which has no meaning for users or applications. Users can share, recover, move, and access data more easily with NAS storage. However, because NAS is file aware, it operates at a higher layer and therefore introduces more latency into the read/write process. Because SAN storage operates at a lower layer it is blazingly fast. For years the question has been: what to use, SAN or NAS? For many companies, the answer is both. While it is not a hard and fast rule, many companies use SAN for their database and e-mail applications and NAS for file storage. However, with the introduction of Ardis Technologies AVFS/iSCSI system companies can now use SAN with NAS simplicity and functionality. AVFS combines the performance benefits of the iSCSI SAN protocol with the NAS intelligence using a single Ethernet network. The iSCSI protocol has emerged as an alternative to Fibre Channel for block based storage area networking. Over the past two years, the adoption of iSCSI in production systems in companies of all sizes and industries has grown dramatically. AVFS uses the iSCSI protocol instead of Fibre Channel to accelerate data access. While the combination of FC SAN and NAS requires two networks, AVFS works over a single network infrastructure. Therefore Ardis Technologies believes that AVFS will ultimately address a much greater market providing SAN level performance with NAS level intelligence over a unified storage network. |

Benefits of the AVFS
AVFS is innovative technology that combines the intelligence and ease of use of NAS with the speed of a SAN with the following benefits:
- 3 times faster than traditional NFS and SMB/CIFS
- runs over existing Ethernet infrastructure
- transparent to users and applications
- project and File Level based Sharing
- Windows, Mac OSX and Linux client support
- clients can use either NFS, SMB/CIFS or AVFS access
- Storage servers support more clients, users and applications than with NFS or SMB/CIFS
