The data mover accesses data from the storage groups created on the PowerMax and provides host access using the I/O modules that support the NAS protocols, for example NFS and CIFS.
Data mover I/O options
Using PCI passthrough, the following I/O modules are available for the NAS services on the data mover:
- 4-port 1 Gb BaseT Ethernet copper module
- 2-port 10 Gb BaseT Ethernet copper module
- 2-port 10 Gb Ethernet optical module
- 4-port 8 Gb Fibre Channel module for NDMP back-up to tape use; there is a maximum of 1 per DM
Notes:
- The 4-port 8 Gb Fibre Channel module can be ordered separately and added at a later time.
- There must be at least one Ethernet I/O module for each Data Mover.
- At present, PowerMax and VMAX All Flash ships by default, with a single 2-port 10 Gb optical I/O module.
- To get others, an RPQ, or hardware upgrades or replacements need to be done.
