iSCSI Switch Fabric, S60

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


Force10 S60 is pitched as a ToR switch for 1/10 GbE access at the network edge. It is equipped with the industry’s largest packet buffer (1.25 GB), enabling it to deliver lower application latency and maintain predictable network performance even when faced with significant spikes in network traffic. It provides 48 line-rate GbE ports and up to four optional 10 GbE uplinks in just 1 RU.

I have come across these switches in numerous iSCSI deployments. Due to the huge buffer size they offer, they are tailor made for traffic of a bursty nature, as typical in iSCSI.

I will just provide a quick & dirty config for a simple iSCSI setup on these switches, when used in a stack of two.
