However, how to buy an optimal 48 port switch for different network environment confuses many people. This article will make an analysis of 48 port switch for your buying guide.

What to Consider for Buying 48 Port Switch?

To buy an optimal 48 port switch for your network, one should take several factors into consideration. Above all, choose managed over unmanaged if possible. 48 port managed switch has advanced features in reliable performance, traffic control, custom management and security regulation. For modern applications requiring for high network privacy and resiliency, 48 port gigabit switch managed is a must. Besides, here lists other important factors for 48 port switch managed selection.

how to choose 48 port switch

·Capacity

What kind of virtualization applications are you implementing? Do they require extra high switching capacity? Generally 48 port switches in the market come with 2 different speed basis: 48 port gigabit switch and 48 port 10Gb switch. For average customers without special requirements 48 port gigabit switch can well meet their demands. But for speed pursuers 48 port 10Gb switch should be deployed for smooth operation in high traffic.

·Uplink Configuration

In addition to regular port, pay attention to the uplink port on 48 port switch. For multiple switch connection, 48 port gigabit switch often comes with several 10G SFP+ uplink ports whereas 10Gb switch comes with 40G QSFP+ or even 100G QSFP+ uplink ports for link aggregation. With a few corresponding uplink ports reserved, the 48 port gigabit switch can access to 10G core switch. And 48 port 10Gb switch can cater for future demands like next generation Metro, Dater Center and Enterprise networks.

·Power over Ethernet

For situations where power outlets are unavailable for cabling devices, 48 port PoE switch is a natural fit. A typical aforesaid case is for connecting Powered Devices (PD): IP cameras, VoIP phones and wireless access points (AP). By deploying 48 port PoE gigabit switch, you can easily put an IP surveillance camera anywhere on the ceiling.

What Are the Cheap 48 Port Switch Recommendations?

Gigabit Switch with 10G Uplink Recommendation

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.

Gigabit Switch with 10G Uplink: Choose 1000Base-T Copper Switch or Fiber SFP Switch

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.

25G Switch Vs. 40G Switch: How to Choose?

25G Ethernet and 40G Ethernet are two “transiting” approaches for upgrading network from 10G to 100G. Some analysts believe 25G could be the second highest Ethernet server connectivity technology sold and shipped in the next five years, behind 10G. Meanwhile, a number of comments from industry experts declaring that 40G Ethernet is dead. Is that true? And how to make a right decision? This passage would give a brief introduction on 25G switch and 40G switch and put emphasis on 25G switch Vs. 40G switch.

25G Switch

25G technology is the new standard that offer significant density, cost and power benefits for server to top of rack connections. Its single higher speed 25 Gb/s lanes maximize bandwidth and switch fabric utilization. A single lane per physical port maximizes the number of connected servers or uplinks per switch. Generally, 25G switch is a 48 port switch on the 25G switch market right now. Nowadays, many major brands of switch manufactures have launched their 25G switch, such as Cisco, Juniper, Arista, Mellanox, Dell.

40G Switch

Comparing with 25G switch, 40G switch is much familiar to us. A 40G switch generally refers to the data speeds of the ports feeding into the switch. Hence, a 40G switch has 40 Gb/s ports. The overall switching capacity of the 40G switch will be much higher depending on the total number of ports and the power of the switching fabric itself. According to Infonetics Research in early 2015, 40Gb Ethernet switch has been popular in the data center market while 100G switch is more popular with service providers. And thus, 40G Ethernet and 40G switch are not so dead like being mentioned in the fast paragraph.

25G switch Vs. 40G switch

—Switch Compatibility

Relatively speaking, 25G switch is less common on the market. In terms of 25G switch compatibility, that is depending the switch supplier. Just take Arista 25G switch for an example, the majority of their 25G switches and Network Interface cards offer backward compatibility to 10G, there is the flexibility to manage a gradual migration to higher speed servers and mix and match port speeds. All SFP based 25G ports on Arista switches and 25G NICs from Cavium can be used at 10G speed. The compatibility of 40G switch also depends on the switch brands. But as a new emerging technology, 25G switch has higher compatibility than 40G switch.

—Port and system density

High performance 25GbE chips use single-lane 25G serializer-deserializer (Serdes) technology similar in operation to 10GbE but delivering 2.5 times the performance, thus reducing the power and cost per gigabit significantly. 25G provides higher port and system density than a comparable 40G solution. Both power savings and higher density results in lower cooling requirements and operational expenditure for data center operators.

—Connection Option

Switch-to-server or switch-to-switch (or switch-to-blade switch) are two connection options for 25G switch connection. Right now, network vendors are positioning 25G only for switch-to-server. Until now, no network vendor advertising 25G for switch-to-switch—Cisco doesn’t even offer a 25G fiber transceiver, and HPE has priced theirs higher than 40G and 100G transceivers. In other words, no one is talking about 25G for switch-to-switch links right now. We shall see this in 2018.

—Cabling

25G twinax works best within a single rack with a top-of-rack switch and 1 and 2 meter cables. 25G with 3+ meter cables requires forward error correction (FEC), which adds ~250ns of one-way latency and may introduce vendor interop issues. If you’re adopting 25G, plan to densely pack compute into 10kVA–12kVA racks. 40G DAC cable is more expensive than 25G DAC cable based on the identical cable length.

25G Switch Vs. 40G Switch: How to Choose?

Through the above description and comparison, we are cleared about some pros and cons of 25Gb Ethernet switch and 40Gb Ethernet switch as well as 25G switch Vs. 40G. As for how to choose the best one, that depends on your demand and usage environment. 25G switch uses less power and produce less heat than 40G, but it is limited at 25G distance. For data center network connectivity, 100G switch is more of a smart choice than 25G switch and 40G switch. In campus and access networks with their long fiber runs and low bandwidth needs, 40G switch is more worthy to buy. So far it seems that 25G switch is not a cost-effective solution.
