Page 16: Overview
Overview This chapter introduces storage area network (SAN) and Fibre Channel technologies, provides an overview of the HP Surestore Director FC-64, and describes the director’s capabilities and features. The 64-port director provides dynamic switched connections between Fibre Channel servers and devices in a SAN environment. Switches are managed and controlled through: •...
Page 17 Figure 1 Rack-Mount Directors and HP EFC Server The director supports mainframe and open-systems interconnection (OSI) computing environments and provides data transmission and flow control between device node ports (N_Ports) as dictated by the Fibre Channel Physical and Signaling Interface (FC-PH 4.3). The director provides dynamic switched connections for servers and devices manufactured by multiple original equipment manufacturers (OEMs).
Page 18: Director Overview
Director Overview The HP Surestore Director FC-64 provides high-performance port connections to end devices such as servers, mass storage devices, and other peripherals in a Fibre Channel switched network. Up to 64 Fibre Channel connections are provided through generic ports (G_Ports).
Page 19 • Low latency The latency is less than two microseconds between transmission of a frame at a source port to receipt of the frame at the corresponding destination port (with no port contention). • Local control Actions taking place at a device N_Port seldom affect operation of other ports, therefore servers need to maintain little or no information about other connected devices in a SAN.
Page 20 – An arbitrated loop topology connects multiple device node loop ports (NL_Ports) in a loop (or hub) configuration without benefit of a multiswitch fabric. Although the director does not support direct connection of arbitrated loop devices, such devices can communicate with the director through heterogeneous Fibre Channel devices. Contact your local HP sales office for supported devices.
Page 21: Director Management
Director Management Management access to the director is provided through an Ethernet LAN connection to the director’s control processor (CTP) card (out-of-band management). A LAN connection is required for each director. The following out-of-band management access methods are provided: • Management through the Enterprise Fabric Connectivity Manager (HP EFC Manager), and Product Manager applications.
Page 22 Figure 2 illustrates out-of-band director management. Figure 2 Out-of-Band Director Management Director Overview...
Page 23: Director Features
Director Features In addition to performance features and out-of-band management, the director provides: • High-availability features. • Connectivity features. • Security features. • Serviceability features. High-Availability Features Pairs of critical field-replaceable units (FRUs) installed in the director provide redundancy in case a FRU fails. When an active FRU fails, the backup FRU takes over operation automatically (failover) to maintain director and Fibre Channel link operation.
Page 24: Connectivity Features
• Power supplies The director contains two power supplies that share the electrical operating load. If one power supply fails, the other supply handles the full load. Separate receptacles at the rear of the director provide facility input power to each supply. For full redundancy, input power for each receptacle should come from a different source.
Page 25: Security Features
• Extended distance support (director-to-director): HP supports the following director-to-director long distance connections: – Up to ten kilometers using longwave SFP interswitch link (ISL) connections. – Up to 100 kilometers by setting a port’s buffer-to-buffer credit (BB_Credit) value to 60 and using dense wavelength division multiplexing (DWDM) equipment. HP supports DWDM customer-supplied equipment.
Page 26: Serviceability Features
• Remote user restrictions Remote user access to directors is either disabled or restricted to configured IP addresses. • SNMP workstation restrictions SNMP workstations can only access management information base (MIB) variables managed by the director SNMP agent. SNMP workstations must belong to SNMP communities configured through the Product Manager application.
Page 27 • System and threshold alerts, event logs, audit logs, link incident logs, threshold alert logs, and hardware logs that display director, Ethernet link, and Fibre Channel link status at the HP EFC Server or a remote workstation. • Diagnostic software that performs power-on self-tests (POSTs) and port diagnostics (internal and external loopback test).
Page 28 • SNMP management using the Fibre Alliance MIB that runs on the HP EFC Server. Up to 12 authorized management workstations can be configured through the HP EFC Manager application to receive unsolicited SNMP trap messages. The trap messages indicate operational state changes and failure conditions. For additional information, refer to the hp surestore director fc-64 SNMP Support Manual (A6534-90908).

The system error LED illuminates when the director detects an event requiring immediate operator attention, such as a FRU failure. The LED remains illuminated as long as an event is active. The LED extinguishes when the Clear System Error Light function is selected from the Product Manager application.
Page 33: Fpm Card
FPM Card Each FPM card provides four full-duplex generic ports (G_Ports) that transmit or receive data at 1.0625 gigabits per second (Gbps). G_Port functionality depends on the type of cable attachment. FPM cards use non-open fiber control (OFC) Class 1 laser transceivers that comply with Section 21 of the Code of Federal Regulations (CFR), Subpart (J) as of the date of manufacture.
Page 34 – The green LED illuminates (or blinks if there is active traffic) and the amber LED extinguishes to indicate normal port operation. – The amber LED illuminates and the green LED extinguishes to indicate a port failure. – Both LEDs extinguish to indicate a port is operational but not communicating with an N_Port (no cable attached, loss of light, port blocked, or link recovery in process).
Page 35: Power Supply
Power Supply Redundant, load-sharing power supplies step down and rectify facility input power to provide 48-volt direct current (VDC) power to director FRUs. The power supplies also provide overvoltage and overcurrent protection. Either power supply can be replaced while the director is powered on and operational. Each power supply has a separate backplane connection to allow for different AC power sources.
Page 36: Fan Module
• A 9-pin maintenance port that provides a connection for a local terminal or dial-in connection for a remote terminal. Although the port is typically used by maintenance personnel, operations personnel use the port to configure network addresses. • An input filter and AC system harness (internal to the FRU) that provides the wiring to connect the AC power connectors to the power switch and power supplies (through the backplane).
Page 37: Backplane
Each SBAR assembly mounts flush on the backplane, and the FRU is comprised of the card and a steel carriage. The carriage provides protection for the back of the card, distributes cooling airflow, and assists in aligning the assembly during installation. The rear of the carriage contains a green LED that illuminates if the assembly is operational and active, and an amber LED that illuminates if the assembly fails.

Page 64: Planning A Fibre Channel San Configuration
Planning a Fibre Channel SAN Configuration A Fibre Channel SAN configuration is created using the HP EFC Server, one or more HP Surestore Director FC-64s, and attached end devices such as servers and storage peripherals. Factors that affect initial SAN configuration planning include: •...
Page 65 • Migration from a proprietary to an open-systems interconnection (OSI) computing environment, and integration of channel and network architectures. OSI computing enables cross-platform communication and increases data availability to customer employees. • Cost savings through higher availability of mission-critical applications and devices. High availability is ensured by multiple device connections through more than one port, or more than one director.
Page 66: Integrating San Technology
• Scalability to meet growth requirements. A director with planned excess port capacity provides OSI connectivity for future servers, devices, and applications. Refer to Capacity Planning on page 53 for additional information. As part of the director planning and installation process, define the enterprise’s computing assets (operating systems, hardware, communication networks, database management systems, and business applications), and document all business and technical issues to be addressed.
Page 67: Capacity Planning
• Point-to-point A dedicated point-to-point connection through the director is simple to implement and should be considered for server-to-storage applications where high performance, high availability, or extended distances are required. • Multiswitch fabric Support of multiswitch fabric operation is a major feature of the director. Consider installation of multiple directors (or other switch elements) to form a high-availability fabric topology that supports multiple, full-bandwidth data transmission paths between servers and devices.
Page 68: Port Connectivity And Fiber-Optic Cabling
Port Connectivity and Fiber-Optic Cabling This section provides planning recommendations for director port connectivity and fiber- optic cabling. Specific recommendations are provided for: • Port requirements (number and type of ports). • Extended-distance ports. • High availability considerations. • Cabling and connectors. •...

In the USA, the SFP module is certified as a Class 1 Laser product, conforming to the requirements contained in Department Of Health and Human Services (DSHS) regulation 21 CFR, Subchapter J.
Page 70: Extended-Distance Ports
Cost Effectiveness Cost is the secondary factor governing the choice of transceiver type and optical fiber. Shortwave laser transceivers and multimode cable offer a less expensive solution if data transmission distance is not critical. Device or Cable Restrictions The choice of transceiver and cable type may be restricted or dictated by: •...
Page 71 To provide high availability and load balancing for Fibre Channel traffic through a multiswitch fabric, multiple ISLs should be provided between directors that participate in critical data transfer paths. Multiple Directors Multiple directors can be installed in the enterprise to provide device availability and multiswitch fabric support.
Page 72: Cabling And Connectors
Cabling and Connectors Each FPM card provides four SFP optic transceivers with duplex LC connectors for attaching fiber-optic jumper cables. Figure 14 illustrates an SFP transceiver and duplex LC connector. Figure 14 SFP Transceiver and LC Duplex Connector Fiber-optic jumper cables are required to connect director ports to servers, devices, distribution panels, or other directors in a multiswitch fabric.
Page 73: Routing Fiber-Optic Cables
Routing Fiber-Optic Cables The director has a maximum of 16 FPM cards (64 ports) that may require fiber-optic cable connections and subsequent cable routing. In a Fibre Channel protocol OSI environment, ports are numbered by physical port number only. Figure 15 shows FPM card numbers (0 through 15) and port numbers (00 through 63).
Page 74 The need for additional fiber-optic cabling could grow rapidly. More cables may be required for connections to additional servers or storage devices, or for connections to additional directors as a multiswitch fabric is developed. The director may need to be moved for more efficient connection to other units, but still maintain its original connections.
Page 75: Hp Efc Server, Lan, And Remote Access Support
HP EFC Server, LAN, and Remote Access Support Out-of-band (non Fibre Channel) console access to the director is provided to perform operations and management functions. These functions are performed from one or more of the following consoles: • Through the HP EFC Server attached to the director’s CTP card. •...
Page 76: Remote User Workstations
HP EFC Server Connectivity The HP EFC Server provides an auto-detecting 10/100 Base-T Ethernet interface that connects to a hub. Each director CTP card also provides an auto-detecting 10/100 Base-T Ethernet interface that connects to a hub. A 12-port hub can be ordered from HP and installed at the top front of the equipment rack.
Page 77: Typical Network Configuration (One Ethernet Connection)
Remote workstations must have access to the LAN segment on which the HP EFC Server is installed. Director administrative functions are accessed through the LAN and HP EFC Server. The LAN interface can be: • Part of the customer’s public 10/100 Mbps LAN segment that provides access to managed directors.
Page 78: Typical Network Configuration (Two Ethernet Connections)
• Part of a second HP EFC Server interface that connects to the customer’s private intranet and allows operation of the Product Manager and Fabric Manager applications from remote user PCs or workstations. Connection to this LAN segment is optional and depends on customer requirements.
Page 79: Snmp Management Workstations
SNMP Management Workstations An SNMP agent that runs on the HP EFC Server can be configured through the HP EFC Manager application. This agent implements the Fibre Alliance management information base (MIB). The agent can be configured to send SNMP trap messages to up to 12 recipients.
Page 80: Security Provisions
Security Provisions Security provisions are available to restrict unauthorized access to the director and attached devices. Access to the director (through the HP EFC Manager application, Product Manager application, and Web server interface) is restricted by implementing password protection. Access to attached computing resources (including applications and data) is restricted by implementing name server zoning.
Page 81: Name Server Zoning
The system administrator can also use the HP EFC Manager application to assign remote workstation access to directors. Remote sessions can be allowed for anyone on a customer intranet, disallowed completely, or restricted to specific workstations. Remote users must log into the HP EFC Manager application with a user name and password, just as when logging in to the local HP EFC server.
Page 82 Benefits of Zoning System administrators create zones to increase network security measures, differentiate between operating systems, and prevent data loss or corruption by controlling access between devices (such as servers and data storage units), or between separate user groups (such as engineering or human resources). Zoning allows an administrator to establish: •...
Page 83 • The domain identification (ID) and physical port number of the director port to which the device is attached. If arbitrated loop devices are included by configuring a Brocade switch in a zone, the zone must be configured by WWN (zoning by port number is not supported by the switch).
Page 84 • Default zone The default zone consists of all devices not configured as members of a zone contained in the active zone set. If there is no active zone set, then all devices attached to the fabric are in the default zone. For the default zone: –...
Page 85 Factors to Consider When Implementing Zoning Consider the following factors when planning to implement zoning for one or more directors in the enterprise. In particular, consider the implications of zoning within a multiswitch fabric. • Reason(s) for zone implementation Determine if zoning is to be implemented for the enterprise. If so, evaluate if the purpose of zoning is to differentiate between operating systems, data sets, user groups, devices, processes, or some combination thereof.
Page 86 Server-level access control is called persistent binding. Persistent binding uses configuration information stored on the server, and is implemented through the server’s HBA driver. The process binds a server device name to a specific Fibre Channel storage volume or logical unit number (LUN), through a specific HBA and storage port WWN. For persistent binding: •...

Page 88: Multiswitch Fabric Support
Multiswitch Fabric Support A Fibre Channel topology that consists of one or more interconnected switch (or director) elements is called a fabric. The director operational software provides the ability to interconnect directors (through E_Port connections) to form a multiswitch fabric. Fabric elements cooperate to receive data from the N_Port of an attached device, route the data through the proper switch ports (F_Ports), and deliver the data to the N_Port of a destination device.
Page 89: Fabric Topology Limits
Fabric Topology Limits Operation of multiple directors in a fabric topology is subject to the following topology limits. Consider the impact of these limits when planning the fabric. • Fabric Elements Up to 16 interconnected directors are supported in a single fabric. Each fabric element is defined by a unique domain identification (domain ID) that ranges between 1 and 15.
Page 90 connections. In addition, each director in the fabric must be assigned a unique preferred domain ID. When planning to implement a fabric topology, consider the following connectivity and cabling concepts: • Physical characteristics and performance objectives Most enterprises have unique configurations determined by the characteristics of end devices, fabric elements, cost, and the installation’s performance objectives (such as high data transfer rate or high availability).
Page 91 Table 2 ISL Transfer Rate Versus Fabric Port Availability (Two-Director Fabric) Number of ISLs ISL Data Transfer Rate Available Fabric Ports 1.0625 Gbps 2.1250 Gbps 3.1875 Gbps 4.2500 Gbps 5.3125 Gbps 6.3750 Gbps 7.4375 Gbps 8.5000 Gbps • Load balancing Planning consideration must be given to the amount of data traffic expected through the fabric.
Page 92 Special consideration must also be given to devices that participate in frequent or critical data transfer operations. For example, in Figure 19, suppose device D is a server and device D is a storage unit and both devices participate in a critical nightly backup operation.
Page 93 At least one switch in a multiswitch fabric needs to be set as Principal or Default. If all switches are set to Never Principal, all of the interswitch links (ISLs) will segment. If all but one switch is set to Never Principal and the switch that was Principal goes offline, then all of the other ISLs will segment.
Page 94 • Path selection Directors are not manually configured with data transmission paths to each other. Participating directors automatically exchange information to determine the fabric topology and resulting minimum-hop data transfer paths through the fabric. These paths route Fibre Channel frames between devices attached to the fabric and enable operation of the fabric services firmware on each director.
Page 95 A rerouting delay parameter can be enabled by the Product Manager application that ensures the director guarantees correct frame order delivery. The delay period is equal to the error detect time out value (E_D_TOV) specified in the Product Manager application. Class 2 frames transmitted into the fabric during this delay period are rejected;...
Page 96 – Unresponsive switch Each director in a fabric periodically verifies operation of all attached directors. An ISL E_Port segments if the attached director does not respond to a verification request. – ELP retransmission failure timeout A director that exhibits a hardware failure or connectivity problem cannot transmit or receive Class F frames.

These devices may include servers, storage control devices, and other directors in a multiswitch fabric. Part of this task may have been performed when the configuration was determined. It might be helpful to draw the configuration diagram.
Page 114: Task 12: Assign Port Names And Nicknames
Task 12: Assign Port Names and Nicknames During the planning process, consider assigning names to director ports based upon devices connected to the ports. Though not required, port naming provides convenience and ease of use. Port naming also documents devices that connect through individual ports, and identifies what is attached to each port.
Page 115: Rules For Nicknames
Rules for Nicknames Nicknames can be up to 32 alphanumeric characters in length. Spaces, hyphens, and underscores are allowed within the nickname. Each nickname must be unique (corresponding to a unique WWN). Example nicknames include: Fabric-1 Host system DASD_001 Task 12: Assign Port Names and Nicknames...
