Re: XS708E Jumbo Frames / Firmware-Update issue After some testing, I figured out, that the iSCSI-Connections failed, because Jumbo-Frames weren't processed (correctly). Tests were conducted in July 2007. elm May 15, 2019 1:06 PM ( in response to brian_ctl ) I was advised by Adtran that all of their products including the 5660 with only do 1500 MTU on layer 3 / IP. I've upgraded my network connection from my workstation to my FreeBSD NAS. Layer 3 Stackable 10GbE Managed Switches DS3400 Series Product Highlights supplies can be replaced without affecting switch operation. Currently the smallest and most affordable 8-port 10GbE switches are still ~$600+ and from what I can tell, loud and power hungry. With the jumbo_frames attribute enabled in AIX, an Ethernet payload can be as large as 9000 bytes. MAC Frames are separated by idle bytes in the form of IFGs (Inter-Frame Gap), generally inserted at the RS (Reconciliation Sublayer). CAUSE: It is found that the NC522SFP controller has not set Jumbo Frames. It does seem you have Jumbo packets enabled to some extent (based on "Jumbo Packet - 9014Bytes Enabled") so it is also possible you're dealing with packets getting fragmented as well. Out of stock. VNXe 3200 and ESXi 5. tcp_fin_timeout should be changed to a smaller number than the default. 3x Flow Control Capability Suppression IEEE 802. Jumbo Frames are packet with a bigger payload than the standard 1500 bytes. 3x with dual RJ-45 connectors, providing a total data rate of 20Gbps using standard CAT6 or better UTP cabling connections. My Dell T620/R520 both have Broadcom NetXtreme 5709 which in fact support Jumbo Frames. Side note: the SR-IOV standard will provide an even higher level of VM performance and again not all 10Gbe cards support it. What Makes Them Jumbo? So, why are Jumbo Frames jumbo? They carry much larger payloads than normal Ethernet Frames. The 1st machine has a ZPool wiht 22x 2-way mirror vdevs and a locale FileBench test shows good results. E10G18-T2 delivers superior transmission performance with the capability to offload packet processing and free up CPU resources for more tasks.
