Flow Control – Pause Frames

. When an Ethernet device gets over loaded, flow control allows it to send PAUSE requests to the  devices sending it data to allow the over loaded condition to clear.  If flow control is not enabled and an over loaded condition occurs, the device will drop packets. Dropping packets is much more performance impacting than flow control. 802.3X flow … Continue reading

Force10 S60 – iSCSI configuration example – stacked, isolated.

. First, I would highly recommend you have a view of my earlier post that summarizes the various (platform independent) optimizations you can implement on an iSCSI fabric. These could be configured upfront, or tried  re-actively in case you have any performance or packet loss issues. the post can be found here https://hasanmansur.com/2012/10/14/switch-fabric-setup-for-equalogic-iscsi-powerconnect-switches/ .

Switch fabric setup for iSCSI

. This post summarizes various elements which, in my experience, serve to optimize the iSCSI switch fabric. While it talks about Powerconnect switches, the elements discussed would be relevant to any switch model, used in the particular role. . a)      Global : Arp cache-size 1024 mac address-table aging-time 1230 spanning-tree portfast bpdufilter default : discard … Continue reading
