About SAN Extensions 1 In the global environment, companies with storage area networks (SANs) cannot be limited by distance. Putting distance between SAN islands is important for creating a disaster-tolerant data environment.
About SAN Extensions FC Switch GBIC or SFP connection FC Switch FC Switch WDM box WDM WDM box FC Switch SAN #1 FC Switch FC Switch IP or SONET Gateway Gateway SAN #2 SAN Extension CXO8294B Figure 1: Types of SAN extensions A SAN extension can be used with any Fibre Channel topology. Much of the extension testing performed by HP on third-party vendor equipment was done in environments running replication between extended SANs.
Fibre Channel Over IP 2 Using Internet Protocol over an IP-based network, HP can link sites over any extended distance. Local SANs are connected through an IP network to create an extended SAN. A Fibre Channel–over–Internet Protocol (FCIP) gateway is used at each end of the intersite link. Each FCIP gateway box encapsulates received Fibre Channel (FC) frames into IP packets for transmission over the IP network.
Fibre Channel Over IP Single link The connection between switches linking two sites is called an interswitch link (ISL). A fabric is a network of one or more FC switches. Figure 2 shows an FCIP gateway connection in a single-link fabric. FC Switch A FCIP equipment IP FCIP equipment FC Switch Y CXO8181A Figure 2: Single link IP configuration Dual links Some configurations use two (dual) ISLs for redundancy. This configuration is common where high availability is a requirement.
Fibre Channel Over IP Shared link A shared link configuration, as shown in Figure 4, uses only one ISL between the fabrics. While it is supported, this configuration is not recommended when high availability is necessary, because it does not allow redundancy between SANs. It may also decrease performance because the bandwidth available for storage is shared between the two fabrics.
Fibre Channel Over IP To create dedicated ports between the hosts and the EVA 3000/5000s, all of the host ports and two of the EVA 3000/5000 ports are assigned to zone A on one side of the SAN and to zone C on the other side of the SAN. To create dedicated ports for replication, only ports used by Continuous Access are assigned to zone B. The management server (SAN Appliance or GPS) must be assigned to all three zones, A, B, and C.
Fibre Channel Over IP Click Technical documentation to be directed to the application notes, or click Related information to find the tool. Because of similarities in the method of replication, this tool is also useful in establishing an initial estimate of the performance needs of Continuous Access XP. ■ For DRM environments, use the DRM Performance Estimator. Its use is documented in the Compaq SANworks Data Replication Manager Inter-site Link Performance Analyzer White Paper.
Fibre Channel Over IP 3. While collecting the data in step 2, determine the values for recovery point objective (RPO) and recovery time objective (RTO). RPO is a measure of how much data can be lost due to a problem at the source site and therefore defines how real-time the solution needs to be. RTO tells you how long to get the recovery site going and most include data and application failover and restart.
Fibre Channel Over IP ■ Increase your link bandwidth while normalization is taking place. ■ Determine what data must absolutely be available in a short time after a disaster, and put that data into a copy set. This applies not only to HSG80-based storage arrays, but also with the EVA family of storage arrays. Back up all other data using other non-realtime backup methods. Currently most IP networks do not manage bandwidth to each individual connection.
Fibre Channel Over IP Certified vendor products for FCIP gateway devices The vendor products listed in Table 3 are certified for use as FCIP gateway devices. The vendors are listed in alphabetical order. Each certified device has a corresponding fact sheet, which can be seen in Appendix A. The fact sheet data was provided by the respective product manufacturer. HP does not rate the devices or make recommendations about these vendors. Users should make their own vendor product evaluations.

Wavelength Division Multiplexing 3 Wavelength division multiplexing (WDM) is an optical technology used to add connection capacity over an existing fiber optic network. It works by combining and transmitting multiple optical signals simultaneously at different wavelengths down a single fiber. In effect, one fiber is transformed into multiple virtual fibers. This allows WDM to multiply the effective bandwidth capacity of the optical fiber.
Wavelength Division Multiplexing A key advantage to WDM is that most architectures are protocol and bit-rate independent. WDM-based networks can simultaneously transmit data in Fibre Channel, Internet Protocol (IP), Asynchronous Transfer Mode (ATM), Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH), and Ethernet protocols, and can simultaneously handle multiple bit rates.
Wavelength Division Multiplexing WDM product variations WDM vendors currently offer at least three variations of the products described in this guide.
Wavelength Division Multiplexing Active protocol handling While most WDM systems are designed to be protocol independent, products are available that offer a system with protocol-specific capabilities for Fibre Channel. This design enables digital time division multiplexing (TDM) on top of existing optical multiplexing to support multiple channels per wavelength. This design also allows for network monitoring, digital retiming (to reduce timing jitter), link integrity monitoring, and distance buffering.
Wavelength Division Multiplexing Qualified vendor products for WDM HP supports the use of all WDM-enabled intersite Fibre Channel provided the WDM equipment is configurable to 1- or 2-gigabits per second data rates. Both CWDM and DWDM systems are supported. The switch vendors do not recommend extending the fabric beyond 100 km because of a drop in performance. HP recommends that you not exceed 200 km with a 1-Gb link, and at these limits, to notify users that there will be a decrease in performance.

Fibre Channel Over SONET (FC-SONET) 4 Local SANs can be connected with Synchronous Optical Network (SONET) to create an extended SAN. An FC-SONET gateway is used at each end of an intersite link. Each FC-SONET gateway box encapsulates received Fibre Channel frames into SONET packets for transmission over the network. Similarly, each FC-SONET box extracts the original FC frames from received SONET packets and retransmits them to the destination Fibre Channel node.

Fibre Channel Over SONET (FC-SONET) Dual links A dual-link configuration is the benchmark for disaster protection, because if one link fails, the other link will temporarily handle all data replication. A dual link configuration that is only partially redundant is shown in Figure 10. For enhanced fault tolerance, a customer may choose to contract with two different providers for the two interswitch links (ISLs), including different entries into the data center.
Fibre Channel Over SONET (FC-SONET) Shared SONET link for dual ISLs A shared SONET-link configuration, as shown in Figure 11, uses one ISL between each of the fabrics. While it is workable, this configuration is not recommended because it does not allow redundancy between SAN islands. Performance is similar to the dual-link configuration due to the ability of SONET to completely isolate bandwidth on a single network interface.
Fibre Channel Over SONET (FC-SONET) Performance in a WAN environment When planning for replication across distances, the bandwidth and speed of the link may not be the determining factor in performance of the system. Careful consideration must be given to size of the storage configurations with regard to the ability to manage them over distance. For information on management versus distance, refer to the HP StorageWorks Continuous Access EVA Planning Guide.
Fibre Channel Over SONET (FC-SONET) Continuous Access EVA with VCS V3.01 support Table 20 lists the VCS Version 3.01 specifications for FC switch firmware revisions and the available range of minimum and maximum supported transmission rates for the qualified gateway device. The speeds listed in the table are the minimum and maximum speeds for the device, with the device being capable of speeds within the range. Table 20: VCS Version 3.
Fibre Channel Over SONET (FC-SONET) Continuous Access EVA VCS V3.025 support Due to changes in the firmware introduced in VCS V3.025, the minimum network supported bandwidths for the gateways have changed. At this time, Table 21 lists the minimum quality of service requirements for the intersite network. Table 22 lists the supported switch and gateway pairs with the minimum supported network bandwidth and number of DR Groups.

Long-Distance Optical Transceivers 5 This chapter provides a description of long-distance optical transceivers used in SAN extension products.
Long-Distance Optical Transceivers CXO7435A Figure 13: SFP Long-distance optical transceiver product features Refer to Table 23 for a comparison of features among several types of optical transceivers. Note: The transceiver distances listed below are not exact. You need to determine the link power budget of your fiber before purchasing any of the part numbers below. Table 23: Long-distance optical transceiver product features Transceiver Part number Max.
Long-Distance Optical Transceivers Link power budget The link power budget is the difference between the minimum optical power launched from the transmitter and the minimum acceptable optical power at the receiver input. A link power budget is usually specified in decibels (dBs), and the sum of all losses in an optical line must be less than this number. If the fiber cable between the two sites is leased, have your carrier provide you with the loss in your circuit.
Long-Distance Optical Transceivers Performance considerations The very-long-distance optical transceiver extends the distance between the Fibre Channel switch E_ports. Using credit-based flow control, the credit given to the E_port is eight buffer-to-buffer (bb) credits, and Figure 14 shows how throughput with these credits diminishes over distance. (This loss applies to any transmission media, whether you are using long-distance transceivers, IP, ATM, or WDM.

Certified FCIP Vendor Products If the activate command is completely successful (usually in under 15 seconds), the message “OK” is displayed. After a zoneset is activated, it is stored in the temporary memory of all switches in the fabric. If the attempt is unsuccessful, error messages are displayed, event messages are logged, and an isolated E_Port condition occurs, as indicated by a blinking green LED and solid amber LED combination on the affected port. 7.
Certified FCIP Vendor Products — There are duplicate (matching) zone names within the active zonesets of each fabric, but the zones contain different zone members. ■ Upon fabric segregation, the following actions must be taken to reinitiate the zone merge: — The zone member mismatch causing the failure must be corrected by either removing the mismatched zones from the active zonesets or by matching the zone members within the duplicate zones in each separate fabric.

Certified FCIP Vendor Products A peer-to-peer remote connection (PPRC) zone is required for each fabric, in which the local and remote PPRC controller ports (the right-most controller port, also known as Controller Port 2) are zoned to access each other across the fabric. Host bus adapter (HBA) zones are also required, in which each HBA device is configured in a zone with its corresponding host controller port (the left-most controller port, also known as Controller Port 1).
Certified FCIP Vendor Products The HBA zones are configured similarly to the steps used in setting up the PPRC zones, with the most significant difference being the selection of the Zone IDs. 1. Choose New Zone from the menu bar of the Zone Configuration window. You are prompted to name the zone and select a Zone ID. Name this new zone with a label that is descriptive of the member devices occupying that zone, such as “HBA Zone - OS1.” 2.
Certified FCIP Vendor Products c. Click Apply, and then click OK. Check the right-most column in the gateway port connection line to verify that the desired zones will be exported. The Zone ID numbers should be listed there. 3. Repeat steps 1 and 2 for the remote IPS3300. 4. Save the new zoning configuration on each IPS3300 by returning to the Element Manager for each IPS3300 and choosing Save Configuration on the File menu. 5.

Glossary Glossary This glossary defines terms used in this guide or related to this product and is not a comprehensive glossary of computer terms. Glossary asynchronous mode A mode of operation of a copy set where the write operation reports completion of the command to the host after the data is on the initiating controller, but before completion of the remote command. See also synchronous mode.
Glossary dark fiber Unused fiber optic cable. data rate The amount of data transferred per second by a communications channel, computing device, or storage device. default gateway The default path that a computer or router uses to forward and route data between two or more networks that have different protocols. dense wavelength division multiplexing (DWDM) Transmitting multiple, closely spaced wavelengths through the same fiber. The result is wavelength spacings of 1 nanometer or less.
Glossary Internet Protocol (IP) An address of a device on a network using TCP/IP. interswitch link (ISL) A connection between two switches using their expansion ports. latency The amount of time required for a transmission to reach its destination. link A connection between two adjacent Fibre Channel ports, consisting of a transmit fiber and a receive fiber. An example is the connection between the Fibre Channel switch port and the HSG80 controller.
Glossary single-mode fiber (SMF) Optical fiber designed to allow just a single path of light through the core. The core for a single-mode fiber is extremely thin—less than 10 microns, which makes the signal extremely clean. small form factor pluggable (SFP) GBIC A standard transceiver with specified dimensions that converts electrical signals used by Fibre Channel devices for transmission over either optical or copper media. SFPs are hot swappable. Optical SFPs use LC connectors.
Glossary wavelength The distance an electromagnetic wave travels in the time it takes to oscillate through a complete cycle. Wavelengths of light are measured in nanometers (10-9 m) or micrometers (10-6 m). wavelength division multiplexing (WDM) A technology that uses multiple lasers to transmit several wavelengths of light simultaneously over a single optical fiber.
