Force10 Offers Virtualization-Friendly Ethernet Switch
The S60 is designed to handle virtualized server network traffic.
Force10 Networks has expanded its product line with a new virtualizationfriendly Gigabit Ethernet switch called the S60. As mentioned in this report on The Register, companies are deploying Gigabit Ethernet switches at the tops of their server racks but increasing utilization of servers creates 'rogue waves' on network ports that can swamp Gigabit Ethernet switches.
"A port coming out of the server and going into the switch might burn only 10Mb/sec of bandwidth supporting two virtual machines, but when you push it up to four to ten VMs, you're talking somewhere around 200Mb/sec with spikes that get a bit higher than that, and once you are up to 20 VMs you're pushing Gigabit speeds with spikes that can be significantly higher due to the 'bursty' nature of multimedia and storage applications running in the data center these days.
"The fix for congestion is not necessarily to move to 10 Gigabit switches, according to Force10, but rather to push line rates in a Gigabit switch and give the device ultra-deep buffering to cope with those momentary rogue waves on the network."
