Direct-attached: StarWind can take control of formatted disks (NTFS). Also, StarWind software can present RAW unformatted disks over SCSI Pass Through Interface that enables remote initiator clients to use any type of a hard drive (PATA/SATA/RAID).

External SAN/NAS Storage: SAN/NAS can be connected over Ethernet connectivity and can be used for StarWind HCA as soon as they are provided as block storage (iSCSI). In case it is required to replicate data between NAS systems, there should be 2 NAS systems connected to both StarWind HCA nodes.
