The modern world is developing in full speed, so is the telecommunication industry. Not long ago 10GbE switch had been a luxury, so was exclusively affordable to large enterprises. And many individuals and businesses used 10/100Mb switch and could only get to gigabit switch for 1Gb backbone. However, this situation is changing due to price dropping and proliferating market demand. Now more and more SMBs and individuals are using gigabit switch and attempt to access 10Gb switch. As thus questions like whether to deploy gigabit switch for 1Gb backbone or 10GbE switch as 10Gb backbone has stirred heated discussion on many forums. This article is to give some reference for 1Gb backbone vs 10Gb backbone selection guide.
Simply put, 1Gb backbone refers to the networking configuration that gigabit switch is used in the data center as core switch. A typical scenario in 1Gb backbone configuration is to run 10/100Mb access layer switches with 1Gb uplink back to a central gigabit switch. In this case the 1Gb uplink on the 100Mb switch receives the 1Gbps from the switch gigabit, then divides the 1Gb bandwidth to its terminal endpoints. Restricted by the normal port 10/100Mb, max. 100Mb is available for access points. As thus 100Mb switch has gradually been obsoleted by gigabit switch.
To achieve 1000Mbps and bring in PoE capability, modern operators often use gigabit PoE switch as access switch to cooperate 1Gb backbone gigabit switch. Here is a 1Gb backbone deployment scenario by FS.COM: Employing S5800-48F4S 48 port gigabit SFP switch as 1Gb backbone in the data center. Linking two 24 port PoE switches in the office to connect and power IP phones, wireless APs, desktops and laptops. Then running two wires to link two 8 port PoE switches in the warehouse for IP surveillance.
Figure 1: Deploying FS 48 port gigabit switch with 10Gb uplink as core switch and FS 8/24 port gigabit PoE switches as access switches.
Similarly, 10Gb backbone refers to the configuration that 10GbE switch serves as core switch in the data center. Then running gigabit switches with 10Gb uplink back to the central 10Gb switch. To illustrate 10Gb backbone configuration, here is a deployment scenario. In this case, we deploy S5800-8TF12S 10Gb SFP+ switch as core 10GbE switch in the data center. Using S3800-48T4S 48 port switch and S1600-48T4S 48 port gigabit PoE switch as access switches, we run fiber patch cables to corresponding 10Gb SFP+ uplinks on these access switches. As thus the 10Gb uplink bandwidth can be divided to the access gigabit switch normal port.
Assumption on the case 10 same endpoints are connected to 10 ports on the gigabit Ethernet switch. Then each can obtain max. 1000Mb from the 10Gb uplink bandwidth. In this case the gigabit speed is retained. If the upper layer switch is a gigabit switch, then each endpoint can only get 100Mb.
Figure 2: Deploying S5800-8TF12S 10Gb SFP+ switch as 10Gb backbone, while S3800-48T4S 48 port switch and S1600-48T4S 48 port gigabit PoE switch are for gigabit access switch.
Generally speaking, deploying gigabit switch for a 1Gb backbone vs 10GbE switch for a 10Gb backbone depends heavily on virtualization application. Even in a small office with only several PCs, demanding applications for high bandwidth may require a backbone 10Gb switch. That is, if you or your employees must deal with high-load pictures and videos every day, 10GbE switch backbone is a must to ensure smooth operation and work efficiency. Or you may easily get stuck in network congestion. Say a regular video conference in a midsize enterprise can randomly drop, which wastes time and drag down schedule process.
Also, pay attention to number of users. Counting all the current endpoints: computers, wireless APs, IP phones, etc. And try to measure the load traffic by plotting utilization. Then take future expansion into consideration. If your backbone gigabit switch ports are already hot for using the most bandwidth provided, and you still need to add office devices, then your network is on the verge of severe congestion. In this case 10Gb switch backbone or higher is the choice to go.
All in all, choosing between backbone gigabit switch vs backbone 10GbE switch, there is a bandwidth gap that access endpoints are available. If you deploy 10Gb switch as core switch and gigabit switch with 10Gb uplink as access switch, the normal port on the access switch can get max. 1000Mb bandwidth. However, if the backbone is 1Gb and your access switch is 100Mb, then only max. 100Mb bandwidth can be available in the access switch port. So for 1Gb backbone scenario where one use gigabit switch as core switch, deploying gigabit PoE switch instead of 100Mb switch as access switch is a solution to keep up with 1000Mbps speed.
In summary, 1 Gb backbone gigabit switch vs 10Gb backbone 10GbE switch selection depends on the bandwidth your virtualization applications require. In detail, 10Gb switch shall function as 10Gb backbone in the case mass data transfer is a regular task. Thus the gigabit switch normal ports can share max. 1Gb bandwidth. Otherwise you can remain your 1Gb backbone. But for 1Gb access, deploying gigabit PoE switch to replace your 100Mb access switch is a future-proofing and feasible solution to go. FS SFP switch is a good choice for 1Gb backbone core switch whereas SFP+ switch for 10Gb backbone core switch.
With the tendency for higher speed network, 10Gb switch has already become familiar with home individuals, no longer the privilege of enterprise operators. However, the issue of SFP to SFP+ compatibility always puzzles many network switch users, even some engineers. Will 1Gb SFP transceivers work with 10Gb SFP+ ports on 10Gb switch? Or will 10Gb SFP+ running at 1Gb to link gigabit switch? And If 10Gb optics in a switch can auto-negotiate to 1Gb when the other end is 1Gb? All these related questions origin from the link between 10Gb SFP+ slots on 10Gb switch and 1Gb SFP ports on gigabit switch. Thus this article will reveal the mask of SFP to SFP+ compatibility from this point of view.
Will 1Gb SFP transceivers/modules work with 10Gb SFP+ ports? The answer is “Yes” in most cases. There are many vendors providing 10Gb switches that can take both a 10G SFP+ and a 1G SFP in the 10Gb SFP+ slot, but not at the same time for obvious reasons. This option is supported by dual speed operation. So before plugging a SFP transceiver into the SFP+ port on your 10GbE switch, one must consult your rep to make sure the 10Gb switch port support dual speed.
To achieve link of 10Gb switch port to gigabit switch port, here is a simple guide. Install a 1Gb SFP module on the 10GbE switch SFP+ port and the gigabit switch 1Gb SFP port respectively, then connect the 10Gb switch and the gigabit switch with corresponding 1Gb SFP fiber cable or Ethernet copper cable (eg. Cat6).
Will 10Gb SFP+ running at 1Gb? The answer is definitely “No”. SFP optics do work in SFP+ slots in most cases, but SFP+ optics on 10Gb switch can never work in SFP slots on gigabit switch. The reason is about a power availability thing. As we know, once an module is installed, the speed of the port is decided. Most SFP+ slots are backward compatible with SFP modules to run at 1G speed. However, the SFP slots on gigabit switch cannot support the 10G speed required by SFP+ modules. For instance, most Cisco and FS 10Gb switches support 10G SFP+ and 1G SFP optics on their SFP+ ports. But some Brocade gear and HP A-series models are SFP+ only. One need to double check the compatibility of this switch with the vendor rep.
FS 10Gb switch SFP+ port links to gigabit switch SFP port via 1G SFP modules and fiber patch cable.
Unlike copper SFP modules supporting 10/100/1000 auto-sensing, fiber optics do not support auto-negotiation. Because this technology is based on electrical pluses but not optical pluses. Thus 10Gb SFP+ optics on 10Gb switch can not auto-negotiate down to 1Gb if the other end is gigabit switch. In fact, most SFP and SFP+ transceivers only run at its rated speed and the transceivers at both end of the cable should at the same speed. For example, if a 10Gb SFP+ module is plugged into the 10Gb switch port, it will only run at 10Gb. In this case if you link it to the gigabit switch port, it will not work. When sticking a 1Gb SFP module in the 10G SFP+ port, the 10Gb switch will only run at 1Gb. As thus you can link it to gigabit switch.
Sometimes the 10GbE switch port would lock the speed at 1G until you reconfigure the switch to 10G. It is noted that SFP+ port usually enables a speed under 1G, which means one cannot insert 100Base SFP modules into SFP+ ports on 10Gb switch.
For the issue of SFP to SFP+ compatibility, a simple response is that most SFP+ can take SFP but not vice versa. The uncertain situation requires one to ask their switch vendors for clear reply. Thus 10Gb switch port is possible to link to gigabit switch port to run at 1G speed. The only thing you need to do is to plug each the aforesaid port with a 1Gb SFP module, and then connect the two modules on the 10Gb switch and the gigabit switch with a corresponding fiber patch cable or Ethernet copper cable.
Touching on switching capacity of the modern networks, the invariant rule is: the faster, the better. Of course for large enterprises, 10G network is a lower value. And more often 40G even 100G network is required for data centers. However, for individuals, small and medium-sized business (SMB), 10G network is often out of reach for exorbitant price of 10gbe switch. In this case, Ethernet switch with 10G uplink can help to achieve 10G network. This article will recommend affordable managed gigabit switch with 10G uplink.
Generally there are two gigabit switch with 10G uplink solutions: 1000base-T copper switch and 1G SFP fiber switch. In the current market, 1000base-T gigabit switch with 10G uplink is usually more popular, especially with home individuals, office users and SMBs. The main reason is largely traced back to price discrimination between them. RJ45 copper gigabit switch employs existing Ethernet copper cable (Cat5e/6, etc.) as medium to transmit data, which saves one budget for matched fiber optics of SFP switch. Moreover, the 1000base-T copper switch is backward compatible with legacy networks. However, 1G SFP link owns the edges of reduced electromagnetic interference, lower latency and power consumption over copper link. For advanced users sensitive to aforesaid factors, one can consider taking gigabit switch with SFP uplink.
