M4300-8X8F or M4300-12X12F for iSCSI with iSER
Hi Netgear Community
I need help to find the right Switch.
I want connect 3 Servers that have a 10GB SPF+ Card (http://www.colfaxdirect.com/store/pc/catalog/QL41132HLCU.pdf) with my NAS(https://www.qnap.com/en/product/es1686dc)
OS on 3 Server is ESXi 6.7
Connection Protokoll should be iSCSI with iSER
how Switch can i use?
in the Community i found 2 differents recomendation in one a Netgear say that all M4300 Support PFC but in anohter all except the 8x8f modell 😞
in this Laurent write that all the 4300 can be use for PFC:
Let me take that back: I think you can use M4300 for RoCE.
Please keep me honnest here, but first I believe RoCE can work either in Lossless Ethernet environments (so, in a network with Global Flow Control enabled, or Priority Flow Control - PFC - implemented), or Lossy Ethernet environments (so, without any Flow control).
In Lossy Ethernet environment, RoCE can be configured in Resilient RoCEv2 mode on server/storage side.
M4300 can certainly be configured for RoCE Lossless Ethernet mode instead, either using standard 802.3x Flow Control, or better, the only feature inherited from M6100, namely Priority Flow Control in order to be able to differentiate between different flows.
PFC is available in M4300 CLI . You can download the CLI manual here http://www.netgear.com/support/product/M4300-24X24F#docs
PFC configuration commands and examples can be found starting page 980. Pleae kindly let us know how it goes. Please follow the configuration flow starting page 980.

Here write DaneA all M4300 execpt 8x8f
Hi @TeamlogcitWP,
I inquired your concern to the higher tier of NETGEAR Support. As per the higher tier of NETGEAR Support, iSER is not supported. RDMA over Converged Ethernet (RoCE) using PFC is supported for this type of networking which available on all M4300s except the 8x8 model.
Also, there is no guarantee that there would be plans to support iSER on the M4300-8X8F switch model.

Re: M4300-8X8F or M4300-12X12F for iSCSI with iSER
Thank you for your messahe and your research.
Yes, between these two switches you should go with the M4300-12X12F (XSM4324S-100xxx ordering SKU) instead of the M4300-8X8F (XSM4316S-100xxx ordering SKU). We amended the M4300 datasheet, PFC isn't supported on 16-port 10G versions, only starting 24-port 10G versions due to hardware limitation.
PFC is available in the CLI, not in the Web GUI. You can use the CLI manual and enable PFC on one physical interface (port) or a range of physical interfaces (port) this way, starting page 985:
The following example enables PFC on an interface and enable the lossless (no drop) behavior:
(NETGEAR Switch) >enable
(NETGEAR Switch) #config
(NETGEAR Switch) (config) #interface 1/0/1
(NETGEAR Switch) (config-if-1/0/1) #datacenter-bridging
(NETGEAR Switch) (config-if-dcb) #priority-flow-control mode on
(NETGEAR Switch) (config-if-dcb) #priority-flow-control priority 1 no-drop
(NETGEAR Switch) (config-if-dcb) #exit
(NETGEAR Switch) (config-if-1/0/1) #exit
(NETGEAR Switch) (config) # save
Thank you,
