and cables selection by use case Key factors* influencing the decision 1 Server Bandwidth Depending on the application load requirements, customers typically decide whether they want 1GbE, 10GbE, or 40GbE. In some cases, the decision may also be dictated by the type of traffic e.g. DCB requires 10GbE or higher. Cost Servers claim the highest share of devices deployed in any data center. Choosing a lower cost connectivity option results in a much lower initial deployment cost. Power In any high density server deployment, a connectivity option which consumes lower power results in much lower OpEx. Distance Servers are typically connected to a switch over a very short distance i.e. typically within the same rack or, in some cases, within the same row. Cabling flexibility Some customer prefer to make their own copper cables due to variable distance requirements. This requirement limits the choice of connectivity to copper cables only. 2 Storage Bandwidth On server facing ports, servers typically dictate the per port bandwidth requirement. However, per port bandwidth requirement for the network facing (switch-to-switch) ports depends on multiple factors including amount of traffic generated by the servers, oversubscription ratios, fiber limitations, etc. Distance An inter-switch or switch to router connection could range from a few inches to tens of kilometers. Generally, the price of optics increases as the distance increases. Latency The network topology and application traffic profile (East-west, HPC, computer clusters, etc.) and influence the minimum latency that can be tolerated in the network. Switch 3 Reliability Typical storage traffic is very sensitive to loss. Even a minor loss of traffic may result in major impact on application performance. Qualification Storage vendor qualification or recommendation plays an important role in this decision due to reasons such as customer support, peace of mind, etc. Latency Any time spent in transition is time taken away from data processing. Reducing transition time results in much faster application performance. The result may have a direct impact on customers bottom line e.g. faster processing of online orders. 3 Dell and Cables Connectivity Guide * This is not an exhaustive list of all potential factors influencing a customers decision. The key factors listed here are more commonly seen as influencing the decision of a customer. However, there could be a number of other factors, not listed here, which could have an impact on the final decision.

Frequently Asked Questions 13 Dell and Cables Connectivity Guide

Frequently Asked Questions What are the different types of cables? Cables Optical fiber Traffic carried using light over optical fiber Copper cable Traffic carried using electrical signal over copper conductor Single Mode Fiber (SMF) Allows only a single mode of light to propagate Good for long distance transmission OS1 Appropriate for indoor deployments OS2 Appropriate for outdoor deployments, commonly used for switch to switch connection Lanes are used to achieve higher data transmission rates such as 40GbE and 100GbE Multiple lower rate data streams (10GbE or 25GbE) are grouped in lanes Multi Mode Fiber (MMF) Allows multiple modes of light to propagate Good for short distance transmission FDDI grade 62.5µm, found in legacy systems and not common today OM1 62.5µm, found in legacy systems and not common today OM2 50µm; suitable for 1GbE OM3 50µm laser optimized; ideal for 10GbE OM4 50µm laser optimized; ideal for 10GbE, 40GbE, and 100GbE What is a lane? Twisted pair (RJ-45) Multiple pairs of wires in a cable Cat5/Cat5e Appropriate for short distance; ideal for 1GbE and short distance for 10GbE Custom length cables can be created on site Cat6/Cat6a Appropriate for short distance; ideal for 10GbE Custom length cables can be created on site 40GbE Four lanes carrying 10Gb in each direction The lanes can be copper cables, wavelengths, or fibers Twinaxial (DAC) Like Coaxial cables but with two inner conductors Point to point Appropriate for indoor deployments; ideal for 1GbE, 10GbE, or 40GbE Multiple fixed length cables available Breakout Appropriate for indoor deployments; breakout one 40GbE or 100GbE into multiple links Single connector on one end breaks to multiple connectors on the other end Multiple fixed length cables available 100GbE Four lanes carrying 25Gb or ten lanes carrying 10Gb in each direction The lanes can be copper cables, wavelengths, or fibers 14 Dell and Cables Connectivity Guide

Frequently Asked Questions Can existing 10GbE fiber cables be used for 40GbE? Previously, the answer was no since 10GbE fiber cables have two fibers whereas 40GbE fiber cables have eight or more fibers, as shown below. Typical 10GbE fiber Typical 40GbE fiber Optical Module 2 fibers makes a link e.g. 10G-SR Optical Module Optical Module Multiple fibers, typically 8, makes a link. E.g. 40G-SR4, using 10G per fiber Optical Module Dell has recently introduced a 40GbE LM4 optic which provides customers the flexibility of using the existing 10GbE cables for 40GbE connections. This is accomplished by sending data over 4 wavelengths, each capable of carrying 10GbE, over single fiber. This is shown in the example below. QSFP 40G-LM4 4x10G wavelengths 4x10G wavelengths QSFP 40G-LM4 By using Dell s 40GbE LM4 QSFP+ optics on both ends of the connection, customers are able to leverage existing 10GbE cable infrastructure. This approach significantly lowers the cost of deployment while improving the time to deployment over traditional approach to 40GbE deployments. Are DWDM and CWDM optics just like a regular optic? Users of DWDM optical modules are expected to engineer the link to suit their deployment. Choice of appropriate DWDM mux-demux, optical amplification, CD compensation, etc. to meet specific link budget requirements is left to the end user. Both ends of the link must have Dell DWDM optics. Dell can provide detailed optical transceiver data-sheet upon request. Users of CWDM optical modules can simply connect the two optics using a single mode fiber (SMF) cable just like a regular Ethernet optic is connected. It is not absolutely required to use Dell CWDM optics on both ends. 15 Dell and Cables Conneectivity Guide

Frequently Asked Questions Services & Support Is it ok to install a non-dell optic in a Dell switch? Is it ok to install a non-dell DAC cable in a Dell switch? A customer is generally discouraged from installing non-dell optics in Dell switches. In order to ensure that users enjoy the most reliable network experience with Dell switches, Dell goes through a very stringent and lengthy process of optics validation, qualification, and certification.
