What is the best storage solution for SMBs facing unpredictable data growth—both data protection and right-now access to critical files for users? Of the three most common storage architectures, direct attached storage (DAS), network attached storage (NAS) and storage area networks (SAN), NAS should be the first choice for most SMBs.
NAS offers the cost-effectiveness of 10GB Ethernet with developments like SCSI over IP (iSCSI). Furthermore, NAS communicate over a NFS and CIFS Fibre Channel while SAN devices transmit block-level data over FCP (Fibre Channel Protocol). Nearly any IT administrators can make connections over a LAN or WAN to the NAS data files. With SANs, users are limited to servers that use SCSI Fibre connectivity, while NAS configurations provide wider data file sharing over both Windows and Unix operating systems.
NAS should be connected in the network where sufficient bandwidth supports the usage created by high data volume. NAS is
