Netapp AFF A800 support RoCE and iWARP protocols

[nabeel1988]

Hi, i would like to know if netapp AFF A800 supports protocol RoCE and iWARP.

early reply would be really appreciated.

Hi @nabeel1988,

for what I know,  AFF-A800 does not support those protocols for host conection.

Thank you @maffo

@maffo Mellanox ConnectX-4 adapter can be used to extend Netapp AFF A-800  support for RDMA protoclols such as RoCE?

RoCE & iWRAP not available in ONTAP. FC-NVMe available in ONTAP.

If you interested particularly in RoCE, you may be interested in E-Series EF570.

@Damien_Queen Thanks for the suggention, does E series netapp supports ONTAP RoCE 100gig bandwidth with mellanox NIC adapter? 

[Damien_Queen]

Again ONTAP does not support RoCE (at least for now in 9.4), therefore there are no NIC adapters for FAS/AFF systems supported RoCE.
ONTAP 9.4 does support NVMe over fabrics in the form of FC-NVMe, current FC maximum is 32Gbps.

E-Series storage systems are not compatible with components from FAS/AFF systems, including NIC's.

But E-Series do support RoCE protocol. Not sure about 100Gbps for RoCE.

Also, E-Series support 100Gbps with NVMe over InfiniBand with Mellanox cards. http://www.mellanox.com/blog/2017/11/nvme-fabrics-infiniband-worlds-fastest-storage-network/
