Cloud Storage Gateway (CSG) provides two types of gateways: file gateway and block gateway. Each type of gateway has multiple specifications. This topic describes the features supported by different specifications of these gateways.
File gateways
File gateways support two network transmission protocols: Network File System (NFS)
and Server Message Block (SMB). You can use both protocols to transfer files over
LAN.
- NFS allows you to access file systems in UNIX, such as AIX, HP-UX, and other Linux-based operating systems.
- SMB allows you to access file systems in Windows.

and the cross sign (×) indicates that the feature is not supported.
Block gateways
Block gateways provide data access services by using the Internet Small Computer System Interface (iSCSI) protocol. iSCSI is a storage technology based on the Internet and SCSI-3 protocols. iSCSI can be used to access Windows and UNIX operating systems.
