Networking:

DNS Load Balancing: DNS load balancing helps in selecting an appropriately loaded data LIF and balancing user network traffic across all available data ports (physical, VLANs, or interface groups).

Routed: 8.1 7-Mode uses routed, only supports receiving routing protocol updates using RIP and doesn’t announce routes. In Data 8.1 C-Mode there is a routing group per Vserver for static routes only.

TFTP Server, SFTP, FTPS, DDNS, IPv6 Data Networking: only supported in 7-Mode only

SAN:

Non-disruptive FCP LUN movement between two controllers/node: Supports in 8.1 C-Mode not in 7-Mode.

Enable ALUA and MPIO: It is mandatory to enable in 8.1 C-Mode and have MPIO installed but in 7-Mode (Enable AULA for FCP not required for ISCSI).

C-Mode: Vserver is best for Horizontal scaling feature of Multi-tenancy.

CIFS:

Anti-Virus Scanning: Cluster mode supports onboard antivirus scan using the Sophos and McAfee, we can schedule them to scan at our dispense.

CIFS setup,terminate and restart: In C-Mode the setup, terminate or restart is on the Vserver stop and start basis, cannot use cifs terminate or restart

Local users and groups: Not support on the C-Mode requires AD authentication

Fpolicy and Fsecurity: Not support on the C-Mode currently but in future releases.

VSS: Not support on the C-Mode currently but in future releases.

NFS:

PNFS: C-Mode supports with NFS 3.0 version only
Exports: C-Mode supports for the export policy, no /etc/exports files any more.

Data Protection:

Snapmirror: C-mode supports only volume snapmirrors(asynchronous only) and no qtrees. It doesn’t support snaplock, snapvault, Metrocluster sync-mirror and and snapmirror to tapes (use only NDMP protocol)

Monitoring: C-mode doesn’t support SAN Screen, and protection manager (planned for future release)

WAFL: C-Mode doesn’t support Traditional volumes, qtree based replication,flexclones, and aggr copy.

C-Mode supports the management roles and ability to set the stop times for post-process compression/dedupe.

C-Mode doesn’t support flexshare (Future release),snapdrive for unix (few operating system versions it supports).

C-Mode support v-series for more than 2 paths per array LUN

There is no /etc directory like 7-mode, all the details configurations are stored in RDM’s of root volume.

NDMPCOPY is supported at node level but not at cluster level.
