1 EMC Distance Extension Support SmartOptics July 31, 2015 This Letter of Support (LOS) is a vehicle by which EMC can offer support for a specific vendor solution. A Letter of Support details support for configurations tested at that particular point-in-time and does not imply future updates of the solution. EMC reserves the right to make any future updates to the solution. For instance, updates could be made if future enhancements discovered through testing further fortifies the existing solution and benefits the customer. It is recommended that the customer and distance vendor periodically check for updates to the Letter of Support Navigator at Successful completion of an EMC Engineering-approved test plan with accepted results is required. The Letter of Support for distance extension solutions is defined by the following: Agreement... 2 Configuration diagram... 2 Supported configurations... 3 Important: The information provided in this document is for reference purposes only and does not represent any EMC commitment or change existing policies or agreements. This document can change at any time, without notice. Contact your EMC Representative for details on how this information may apply to your specific environment. 1

2 Agreement The following conditions exist: Any distance extension configuration that is beyond the specified scope of the EMC Letter of Support or the EMC Support Matrix requires an EMC Request for Price Quote (RPQ) submission by the EMC Sales team to EMC Engineering. The configuration displayed in the Supported Configuration section is supported using only the specified recommendations, revisions, and requirements as listed further. Configuration diagram The following diagram shows the preferred distance extension topology configuration.

Wide Area Network This diagram is a conceptual physical configuration of a highly-available point-to-point Fibre Channel switched fabric infrastructure configuration.

3 Although not always possible, it is highly recommended that the customer build out a highly available environment with redundancy (minimum of two Fibre Channel switches, local and remote location, a minimum of two E_ports/ISLs per area, and a redundant 1+1 WAN/dark fiber path). The following configurations are only supported for unprotected WAN configurations (i.e., 1+1). Supported configurations This section contains information on supported configurations. Supported distance extension devices Refer to the following four figures and table for supported distance extension devices. EMC Distance Extension Support, SmartOptics 3

SmartOptics SFP Transceiver - Small Form Factor Pluggable optics to be used in listed Brocade switches. Mux Types - Optical Multiplexer, Passive (no power), Active (Power needed with Monitoring). Active - WDM Products (also known as Transponders or Muxponders) that are AC or DC powered device with GUI management. For a solution to be called Active it usually has an OEO conversion (Optical to Electrical to Optical) to generate a clean signal that can be amplified cleanly as well. Active products are also commonly used to do media conversion. In our cases that is mostly to convert from 850/1310nm coming from the switch to CWDM or DWDM wavelengths. It has SFP+ or XFP interfaces to house a SmartOptics 850nm/1310nm transceiver to accept the corresponding client connection coming from switches. It also has SFP+ or XFP interfaces that face the network side as well. These network side interfaces can house SmartOptics CWDM or DWDM transceivers and interface passive CWDM, DWDM muxes or M-401, M products. Passive - SmartOptics Brocade Certified CWDM or DWDM transceivers reside directly in the Switch and jumper to a completely non-powered Passive CWDM or DWDM mux/demux. Tends to be more limited in distance and channel counts than Active or Semi-Passive solutions.

5 Semi-Passive - Our M-1601 and/or M-401 products are really the only products in the industry to have this designation, so SmartOptics has coined this phrase. The M-Series are unique in that they provide the integrated Passive Mux/Demux, but they also provide integrated line conditioning features, amplifiers and optical monitoring to be able to send the Ethernet or FC signal up to 200Km and allow customer to monitor light levels etc. We do all this without an OEO conversion, so though the M-Series is powered it is technically not Active. The M-Series follows the same approach as Passive in that the SmartOptics DWDM transceivers reside in the switch. Brocade Native 850 / 1310nm - Optics used in Brocade Switches are supported for client-connections to Active Distance Application Type configurations. Please refer to the Supported Distance Extension Device table.

It is mandatory that the SFPs on both local and remote switch associated to the same E_port / ISL is identical in wavelength (i.e., same sfp-partnumber and nano-meter spectrum/nm on both ends). The specified SmartOptics SFPs and MUX-Types devices listed in the Supported Distance Device Table do not participate in extending bb-credits for Fibre Channel flow control. The bb-credits used for Fibre Channel flow control will be sourced from the Fibre Channel Switch E_ports attached utilizing SmartOptics SFPs/MUX (MUX + AMP) devices. Verify that the physical distance and latency experienced at the customer site does not exceed the credit amounts/capabilities of the Fibre Channel Switch resources. Fibre Channel Switch BB-credit provisioning of the E_port may be required depending upon the distance between sites. Fibre Channel link speeds are to be hard-set across all Fibre Channel Switched E_ports using SmartOptics SFPs/MUX (MUX + AMP) devices associated in the distance extension configuration. Consult with the EMC, SmartOptics, or Fibre Channel switch vendor product or administration documents for assistance and further configuration guidance. 6 EMC Distance Extension Support, SmartOptics

7 WAN protection mode support Although not preferred, an unprotected environment can pass Fibre Channel traffic. (Refer to the configuration diagram, which shows a single-full-duplex-wan primary path with no secondary protection path between the distance extension devices). EMC will support an unprotected Distance Protocol solution transmitting and receiving replicated (mission-critical and non-mission-critical) data if the customer understands the implications and risks. (There would be no fault to EMC if related issues were to occur.). Refer to the Support Notes in the following Supported Fibre Channel Switches section for further details.
