Optics and cables selection by use caseKey factors* influencing the decision

Dell Optics and Cables Connectivity Guide3

Storage

Server

Switch

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.

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.

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.

* This is not an exhaustive list of all potential factors influencing a customers decision. The key

factors listed here are more commonly seen as inf luencing 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

Dell Optics and Cables Conneectivity Guide15

Can existing 10GbE fiber cables be used for 40GbE?

Typical 10GbE fiber Typical 40GbE fiber

Optical Module Optical Module2 fibers makes a link

e.g. 10G-SR

Optical ModuleOptical Module

Multiple fibers, typically 8,

makes a link. E.g. 40G-SR4,

using 10G per fiber

Previously, the answer was no since 10GbE fiber cables have two fibers whereas 40GbE fiber cables have eight or more fibers, as shown below.

Dell has recently introduced a 40GbE LM4 optic which provides customers the flexibility of using the existing 10GbE cables for 40GbEconnections. This is accomplished by sending data over 4 wavelengths, each capable of carrying 10GbE, over single fiber. This is shown in theexample below.

QSFP 40G-LM44x10G 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 40GbEdeployments.

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, opticalamplification, 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.



Frequently Asked Questions – Services & Support

Dell Optics and Cables Conneectivity Guide16

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?

In order to ensure that users enjoy the most reliable networkexperience with Dell switches, Dell goes through a very stringent andlengthy process of cables validation, qualification, and certification.

Dell fully stands behind such a solution and, in the unlikely event thata user comes across a problem, Dell’s support personnel will helpaddress the issues.

If a non-Dell DAC cable, which is standards compliant, is plugged into

a Dell switch, the switch will continue to perform as well as the cable

allows. Additionally, since cables are passive components and as long

as the cables are standards based, If Dell Support determines that the

reported issue is caused by the use of non-Dell DAC then they will

recommend that the customer replace the unsupported DAC with

qualified Dell optics.

As a matter of best practice, Dell recommends that end user test non-

Dell optics appropriately, prior to deploying them in production

environment.

Are Dell optics covered under Dell warranty andsupport options?

Dell approved optics are covered by Dell warranty and support options

but there are limitations and different terms based on the type ofwarranty. Please find more detailhere: http://www.dell.com/learn/us/en/19/campaigns/lifetime-warranty. Typically, the warranty support on the Dell approved opticaligns with the hardware warranty.

A customer is generally discouraged from installing non-Dell optics inDell switches.

In order to ensure that users enjoy the most reliable network experiencewith Dell switches, Dell goes through a very stringent and lengthyprocess of optics validation, qualification, and certification. Dell fullystands behind such a solution and, in the unlikely event that a usercomes across a problem, Dell’s support personnel will help address theissues.

If a non-Dell optic is plugged into a Dell switch, the switch will continue

to perform as well as the optic allows. A warning message might be

displayed, indicating that the optics are not supported/tested by Dell

Engineering.

Dell Support will assist customer in case there is a problem. If Dell

Support determines that the reported issue is caused by the use of non-

Dell optics then they will recommend that the customer replace the

unsupported optics with qualified Dell optics. As a matter of best

practice, Dell recommends that end user test non-Dell optics

appropriately, prior to deploying them in production environment.

Are Dell optics covered under the LifetimeLimited Warranty (LLW) for N series products?

Dell approved optics are covered as long as the original customerowns the product.

Q

http://www.dell.com/learn/us/en/19/campaigns/lifetime-warranty









Dell Optics and Cables Conneectivity Guide

Is it ok to install an optic from a Dell switch into Dellserver NICs?

It is very common for customers to use DAC (TwinAx) cables instead of

optics to connect server NICs to switches. Customers have the flexibility to

use either a switch qualified or a server qualified DAC cable.

If a customer chooses to use optics, Dell recommends using a switch

qualified optic in a switch and a NIC qualified optic in a server NIC. Fibre

Channel (FC) HBAs and FC switches ship with pre-installed FC optics.

Customer should use the same optics in both of these products.

Please consult your Dell representative to find a list of qualified optics.

Is it ok to install an optic from a Dell switch into Dellstorage ?

It is very common for customers to use DAC (TwinAx) cables instead of

optics to connect Dell Ethernet based storage ports to switches.

Customers have the flexibility to use either a switch qualified or a storagequalified DAC cable.

If a customer chooses to use optics, Dell strongly recommends using a

storage qualified optic in a storage controller port and a switch qualified

optic in a switch port. Fibre Channel (FC) storage and FC switches ship

with pre-installed FC optics. Customer should use the same optics in both

of these products.

Please consult your Dell representative to find a list of qualified optics.

Are Dell approved optics covered under ProSupport, ProSupport Plus and ProSupportFlex for Data Center?

The Dell approved optics are covered under the same terms and conditions as the ProSupport contract. For example, if a customer purchases a 3 yearNBD ProSupport contract then that Dell approved optic will also be covered NBD for 3 years.

Is it ok to install an optic from one Dell switch into another?

In most cases, the answer is yes. However, it is highly encouraged that the user contact their Dell representative to confirm if there are any specificrequirements or exceptions.

Dell supplied Fibre Channel (FC) optics must be installed in Dell’s FC products. Dell supplied FC optics for Brocade OEM products must be used withBrocade products. Dell FC optics in Brocade switches and Brocade optics in Dell switches are not supported.

F l A k d Q i




Dell Optics and Cables Conneectivity Guide

Is it ok to use a Dell DAC cable to connect a Dell device to a non-Dell device?

Dell DAC should function normally when inter-connecting Dell and non-Dell Devices. However, Dell recommends use of optics in multivendor

environment because there is always a possibility that a non-Dell device may have deviated from the standards based implementation.

Dell Support will assist the customer in case of a problem. However, if Dell Support identifies that the reported issue is caused by use of DAC cables,they will likely recommend the use of optics, instead of DAC.

As a matter of best practice, Dell recommends that the end user test DAC cables, prior to deploying them in multi-vendor inter-connect environment.

Is it ok to use a Dell DAC cable to connect Dell switch to other Dell devices?

Dell provides full and complete support for Dell DAC, when deployed between Dell devices. Any issues attributed to the use of Dell DAC on ,and,between Dell devices, will be investigated by Dell Support

Is it ok to use a DAC cable between a 10bE CNA and a 1GbE switch or 1GbE adapter with 10GbE switch?

It is recommended to use optics instead of DAC if connecting at 1GbE speeds. Additionally, please ensure that both the switch and the server adaptersupport operation at 1GbE because some adapters support 10GbE only.
