Hi All

We are a small company of 25 employees. I am looking to replace the old servers with two new servers with 10gb-t nics. I am looking to buy a Netgear XS712T(cheapest) as our core switch. We have 3 x SG300-28P in our environment.

A cabling company has quoted for pulling the backbone for CAT6A and Fiber OM3. The fiber is cheaper with 4 connections(2 for immediate use, 2 as standby) to the main fiber patch panel in the data center.

I wanted to know if the Cisco Cisco SFP-10G-SR would run on SG-300, providing a backbone of 10GBe. SG-300 provides for SFP support and Cisco SFP-10G-SR is SFP+.

I am looking to replace the 3 x SG300s or the above solution would work?

Many thanks in advanced.

That is the KEY difference between SFP and SFP+ and one of the big clues to if a device supports 10g. You can almost always put a SFP (ie 1g) device in a SFP+ (10g) slot but not the other way around. You will have to replace the sg300 if you really want 10g of bandwidth.

You may want to consider using port aggregation (ie 802.3ad) to get more bandwidth. You may be able to delay the cost to upgrade if you do not actually pass 10g of traffic now.

I am going to assume since the distance is short enough to use cat6a you are not using real long runs so the type of fiber is not as critical. To get the maximum distance on multimode fiber you need to go to OM4 but it tends to be cheaper to go to singlemode fiber and singlemode optics. I know we run almost all our 10g on singlemode fiber except for short patches within a datacenter.
