What type of centralized data storage should I use for 1.5 TB of data across multiple locations?
Greg Schulz explains centralized data storage options for an SMB with 1.5 TB of data across several locations.
Based on the information you provided, it sounds like a network-attached storage (NAS) product is your best bet. Look at NAS systems with multiprotocol support such as block or file systems with iSCSI or Fibre Channel (FC)/FCoE, or NFS and CIFS, and perhaps even AFP for Macs. Choose a NAS system that uses redundant paths and connections that also have dual controllers (nodes, processors, NAS heads) for high-availability (HA).
