Over the last 18 months cheaper, commodity, small port count, but high quality 10Gbps switches have become available. NetGear is a prime example. This means 10Gbps networking is within reach for even the smallest deployments.

Size is an often used measure for technological needs like storage, networking and compute but in many cases it’s way too blunt of a tool. A lot of smaller environments in specialized niches need more capable storage  and networking capacities than their size would lead you to believe. The “Enterprise level” cost associated with the earlier SPF+ based swithes was an obstacle especially since the minimum port count lies around 24 ports, so with switch redundancy this already means 2 *24 ports.  Then there’s the cost of vendor branded SPF+ modules. But that could be offset with Copper Twinax Direct Attach cabling (which have their sweet spots for use) or finding functional cheaper non branded SFP+ modules. But all that isn’t an issue anymore. Today 10GBase-T card & switches are readily available and ready for prime time. The issues with power consumption and heat have been dealt with.

While vendors like DELL have done some amazing work to bring affordable 10Gbps switches to the market it remained a obstacle for many small environments. Now with the cheaper copper based, low port count switches it’s become a lot easier to introduce 10Gbps while taking away the biggest operational pains.

• You can start with a lower number of 10Gbps ports (8-12) instead of  a minimum of 24.
• No need for expensive vendor branded SPF+ modules.
• Copper cabling (CAT6A) is relatively cheap for use in a rack or between two racks and for this kind of environment using patch lead cables isn’t an issue
• Power consumption and heat challenges of copper 10Gbps has been addressed.

So even for the smallest setups where people would love to get 10Gbps for live migrations, hypervisor host backups and/or the virtual network it can be done now. If you introduce these for just CSV, live migration, storage or backup networks you can even avoid having to integrate them into the data network. This makes it easier, non disruptive & the isolation helps puts minds at easy about potential impacts of extra traffic and misconfigurations. Still you take away the heavy loads that might be disrupting your 1Gbps network, making things well again without needing further investments.

So go ahead, take the step and enjoy the benefits that 10Gbps bring to your (virtual) environment. Even medium sized shops can use this as a show case while they prepare for a 10Gbps upgrade for the server room or data center in the years to come.
