Go to: /techcenter/storage/ and select DellCompellent in the Table of Contents.51 About the SC4020 Storage ControllerThe SC4020 storage controller provides the central processing capabilities for the Storage Center Operating System (OS), application software (Storage Center System Manager), and management of RAID storage.Storage Center Hardware ComponentsThe Storage Center described in this document consists of an SC4020 storage controller, enterprise-class switches, and expansion enclosures.The SC4020 storage controller supports SC200 and SC220 expansion enclosures.SC4020 Storage ControllerThe SC4020 is a 2U storage controller that supports up to 24 2.5–inch hot-swappable SAS hard drives installed vertically side-by-side.The SC4020 consists of two storage controller modules with multiple IO ports that provide communication with servers and expansion enclosures.SwitchesDell offers enterprise-class switches as part of the total Storage Center solution.The SC4020 supports Fibre Channel (FC) and Ethernet switches, which provide robust connectivity to servers and allow for the use of redundant transport paths. Fibre Channel (FC) or Ethernet switches can provide connectivity to remote a Storage Center to allow for replication of data. In addition, Ethernet switches provide connectivity to a management network to allow configuration, administration, and management of the Storage Center.NOTE: The cabling between the storage controller and switches (and servers) is referred to as front‐end connectivity.Expansion EnclosuresExpansion enclosures allow the data storage capabilities of the SC4020 to be expanded beyond the 24 internal drives in the storage controller chassis.Storage Center supports a total of 120 drives per system. This total includes the drives in the SC4020 storage controller and the drives in the SC200/SC220 expansion enclosures.The SC4020 supports up to eight SC200 expansion enclosures, up to four SC220 expansion enclosures, or any combination of SC200/SC220 expansion enclosures as long as the total drive count of the system does not exceed 120.6About the SC4020 Storage ControllerStorage Center Architecture OptionsA Storage Center that contains an SC4020 storage controller can be deployed in two configurations:•An SC4020 storage controller without SC200/SC220 expansion enclosures.Figure 1. SC4020 without Expansion Enclosures•An SC4020 storage controller with one or more SC200/SC220 expansion enclosures.Figure 2. SC4020 with Two Expansion EnclosuresStorage Center sites can be co-located or remotely connected and continue to share and replicate data between sites. Replication duplicates volume data to support a disaster recovery plan or to provide local access to a remote data volume. Typically, data is replicated remotely to safeguard against data threats as part of an overall disaster recovery plan.About the SC4020 Storage Controller7Storage Center CommunicationA Storage Center uses multiple types of communication for both data transfer and administrative functions. Storage Center communication is classified into three types: front end, back end, and system administration.SC4020 Storage Controller with Fibre Channel HBAsFigure 3. SC4020 Storage Controller Fibre Channel Front-End Communication8About the SC4020 Storage ControllerSC4020 Storage Controller with iSCSI HBAsFigure 4. SC4020 Storage Controller iSCSI Front-End CommunicationFront-End ConnectivityFront-end connections provide IO paths from servers to storage controllers and replication paths from one Storage Center to another Storage Center. The SC4020 provides two types of front-end ports:•Front-end Fibre Channel ports: Hosts, servers, or Network Attached Storage (NAS) appliances access storage by connecting to the storage controller Fibre Channel ports through one or more FibreChannel switches. The Fibre Channel ports are located on the back of the storage controller, but are designated as front-end ports in Storage Center.•Front-end iSCSI ports: Hosts, servers, or Network Attached Storage (NAS) appliances access storage by connecting to the storage controller iSCSI ports through one or more Ethernet switches. TheAbout the SC4020 Storage Controller9SC4020 also uses iSCSI ports to replicate data to a remote Storage Center. The iSCSI ports are located on the back of the storage controller, but are designated as front-end ports in Storage Center.CAUTION: The embedded iSCSI ports are only used for replication to another Storage Center.The embedded iSCSI ports cannot be used for front‐end connectivity to servers.Back-End ConnectivityBack-end connectivity is strictly between the storage controller and expansion enclosures, which hold the physical drives that provide back-end expansion storage.The SC4020 supports SAS connections to SC200/SC220 expansion enclosures. SAS provides a point-to-point topology that transfers data on four lanes simultaneously. Each lane can perform concurrent IO transactions at 6 Gbps. The SAS ports are located on the back of the storage controller, but are designated as back-end ports in Storage Center.System AdministrationTo perform system administration, the Storage Center communicates with computers using Ethernet and serial ports.•Ethernet port: Used for configuration, administration, and management of Storage Center.NOTE: The baseboard management controller (BMC) does not have a physical port on theSC4020. The BMC is accessed through the same Ethernet port that is used for Storage Centerconfiguration, administration, and management.•Serial port: Used for initial configuration of the storage controller modules. In addition, it is used to perform support only functions when instructed by Dell Technical Support Services.SC4020 Storage Controller HardwareThe SC4020 storage controller ships with two power supply/cooling fan modules and two redundant storage controller modules.Each storage controller module contains the communication ports of the storage controller.SC4020 Front Panel Features and IndicatorsThe front panel of the SC4020 contains power and status indicators, a system identification button, and a seven-segment display.In addition, the hard drives are installed and removed through the front of the storage controller chassis.Figure 5. SC4020 Front View10About the SC4020 Storage ControllerSC4020 Back-Panel Features and IndicatorsThe back panel of the SC4020 shows the storage controller module and power supply indicators.Figure 6.

SC4020 Storage Controller Module with iSCSI PortsAbout the SC4020 Storage Controller1314About the SC4020 Storage ControllerSC4020 DrivesDell Enterprise Plus Drives are the only drives that can be installed in an SC4020 storage controller. If a non-Dell Enterprise Plus Drive is installed, Storage Center prevents the drive from being managed.The indicators on the drives provide status and activity information.Figure 9. SC4020 Hard DriveSC4020 Drive NumberingIn an SC4020 storage controller, drives are numbered from left to right starting from 0.Figure 10. SC4020 Drive NumberingAbout the SC4020 Storage Controller152 Connect the Front EndFront-end cabling refers to the connections between the storage controller and servers.Front‐end connections can be made using Fibre Channel or iSCSI interfaces. Dell recommends connecting servers to the storage controller using the most redundant options available.Types of Redundancy for Front-End ConnectionsFront-end redundancy is achieved by eliminating single points of failure that could cause a server to lose connectivity to Storage Center.Depending on how Storage Center is configured, the following types of redundancy are available.•Path redundancy: When multiple paths are available from a server to a storage controller, a server configured for multipath IO (MPIO) can use multiple paths for IO. If a path fails, the server continues to use the remaining active paths.•Storage controller module redundancy: If one storage controller module fails, the front-end ports fail over to the functioning storage controller module. Both front-end connectivity modes (legacy mode and virtual port mode) provide storage controller module redundancy.•Port redundancy: In virtual port mode, if a port goes down because it is disconnected or there is a hardware failure, the port can fail over to another functioning port in the same fault domain. Port redundancy is available only for Storage Centers operating in virtual port mode.Related LinksMultipath IOVirtual Port ModeLegacy ModeMultipath IOMultipath IO (MPIO) allows a server to use multiple paths for IO if they are available.MPIO software offers redundancy at the path level. MPIO loads as a driver on the server, and typically operates in a round-robin manner by sending packets first down one path and then the other. If a path fails, MPIO software continues to send packets down the functioning path. MPIO is operating-system specific.MPIO BehaviorWhen MPIO is configured, a server can send IO to both storage controller modules.However, a single volume is owned by one storage controller module at a time. Even if there are active paths from a server to both storage controller modules, IO for a single volume is always processed by one storage controller module. This limitation only applies to individual volumes. If a server has two or16Connect the Front Endmore volumes owned by different storage controller modules, the server can send IO to both storage controller modules.MPIO Configuration Instructions for ServersTo use MPIO, configure MPIO on the server prior to connecting the Storage Center front end.To configure MPIO on a server, see the Dell document that corresponds to the server operating system. Depending on the operating system, you may need to install MPIO software or configure server options. Table 1. MPIO Configuration DocumentsFront-End Connectivity ModesStorage Center uses either virtual port mode or legacy mode to transport data to servers that use SAN storage.In virtual port mode, all ports are active, and if one port fails the load is distributed between the remaining ports within the same fault domain. In legacy mode, front-end IO ports are configured in pairs of primary and reserved ports.Failover Behavior for Legacy Mode and Virtual Port ModeLegacy mode and virtual port mode behave differently during failure conditions because they use different mechanisms to provide fault tolerance.Table 2. Differences between Legacy Mode and Virtual Port Mode Failover BehaviorConnect the Front End17Virtual Port ModeVirtual port mode provides port and storage controller module redundancy by connecting multiple active ports to each Fibre Channel or Ethernet switch.In virtual port mode, each physical port has a WWN (World Wide Name) and a virtual WWN. Servers target only the virtual WWNs. During normal conditions, all ports process IO. If a port or storage controller module failure occurs, a virtual WWN moves to another physical WWN in the same fault domain. When the failure is resolved and ports are rebalanced, the virtual port returns to the preferred physical port. Virtual port mode provides the following advantages over legacy mode:•Increased connectivity: Because all ports are active, additional front-end bandwidth is available without sacrificing redundancy.•Improved redundancy–Fibre Channel: A Fibre Channel port can fail over to another Fibre Channel port in the same fault domain on the storage controller module.–iSCSI: In a single fault domain configuration, an iSCSI port can fail over to the other iSCSI port on the storage controller module. In a two fault domain configuration, an iSCSI port cannot fail over to the other iSCSI port on storage controller module•Simplified iSCSI configuration: Each fault domain has an iSCSI control port that coordinates discovery of the iSCSI ports in the domain. When a server targets the iSCSI port IP address, itautomatically discovers all ports in the fault domain.Fault Domains in Virtual Port ModeFault domains group front-end ports that are connected to the same Fibre Channel fabric or Ethernet network. Ports that belong to the same fault domain can fail over to each other because they have the same connectivity.The following requirements apply to fault domains in virtual port mode:• A separate fault domain must be created for each front-end Fibre Channel fabric or Ethernet network.• A fault domain must contain a single type of transport media (FC or iSCSI, but not both).•Dell recommends configuring at least two connections from each storage controller module to each Fibre Channel network (fault domain) or Ethernet network (fault domain).Requirements for Virtual Port ModeThe following requirements must be met to configure a storage controller in virtual port mode.Table 3. Virtual Port Mode Requirements18Connect the Front EndRelated LinksFibre Channel ZoningExample Virtual Port Mode ConfigurationThe following figure shows a Storage Center in virtual port mode connected to servers with Fibre Channel HBAs and two fault domains.Figure 11. Virtual Port Mode Example with FC1.Server 12.Server 23.FC switch 14.FC switch 25.Storage controller module 16.Storage controller module 2NOTE: To use multiple primary paths simultaneously, the server must be configured to use MPIO. The following table summarizes the failover behaviors for this configuration.Connect the Front End19Table 4. Virtual Port Mode Failover ScenariosLegacy ModeLegacy mode provides storage controller module redundancy for a Storage Center by connecting multiple primary and reserved ports to each Fibre Channel or Ethernet switch.In legacy mode, each primary port on a storage controller module is paired with a corresponding reserved port on the other storage controller module. During normal conditions, the primary ports process IO and the reserved ports are in standby mode. If a storage controller module fails, the primary ports fail over to the corresponding reserved ports on the other storage controller module. This approach ensures that servers connected to the switch do not lose connectivity if one of the storage controller module fails. For optimal performance, the primary ports should be evenly distributed across both storage controller modules.Fault Domains in Legacy ModeEach pair of primary and reserved ports is grouped into a fault domain in the Storage Center software. The fault domain determines which ports are allowed to fail over to each other.The following requirements apply to fault domains in legacy mode on a Storage Center:• A fault domain must contain one type of transport media (FC or iSCSI, but not both).• A fault domain must contain one primary port and one reserved port.•The reserved port must be on a different storage controller module than the primary port. Requirements for Legacy ModeThe following requirements must be met to configure a storage controller in legacy mode.Table 5. Legacy Mode Requirements20Connect the Front EndRelated LinksFibre Channel ZoningExample Legacy Mode ConfigurationThe following figure shows a Storage Center in legacy mode connected to servers with Fibre Channel HBAs and four fault domains.•Fault domain 1 (shown in orange) is comprised of primary port P1 on storage controller module 1 and reserved port R1 on storage controller module 2.•Fault domain 2 (shown in blue) is comprised of primary port P2 on storage controller module 2 and reserved port R2 on storage controller module 1.•Fault domain 3 (shown in green) is comprised of primary port P3 on storage controller module 1 and reserved port R3 on storage controller module 2.•Fault domain 4 (shown in purple) is comprised of primary port P4 on storage controller module 2 and reserved port R4 on storage controller module 1.Figure 12. Legacy Mode Example with Fibre Channel1.Server 12.Server 23.FC switch 14.FC switch 25.Storage controller module 16.Storage controller module 2NOTE: To use multiple paths simultaneously, the server must be configured to use MPIO.The following table summarizes the failover behaviors for this configuration.Connect the Front End21Table 6. Failover Scenario BehaviorsFibre Channel ZoningWhen using Fibre Channel for front-end connectivity, zones must be established to ensure that storage is visible to the servers. Plan the front-end connectivity using zoning concepts discussed in this section before starting to cable the storage controller.Zoning can be applied to either the ports on switches or to the World Wide Names (WWNs) of the end devices. Zones should be created using a single initiator (using physical WWNs) and multiple targets (using virtual WWNs). The virtual WWNs from each storage controller module must be included in the zone with each host’s WWN.NOTE: WWN zoning is recommended for virtual port mode.Port Zoning GuidelinesWhen port zoning is configured, only specific switch ports are visible. If a storage device is moved to a different port that is not part of the zone, it is no longer visible to the other ports in the zone.Table 7. Guidelines for Port Zoning22Connect the Front EndWWN Zoning GuidelinesWhen WWN zoning is configured, a device may reside on any port or change physical ports and still be visible because the switch is seeking a WWN.Table 8. Guidelines for WWN ZoningUsing SFP+ Transceiver ModulesTheSC4020 storage controller supports an optical 10Gb iSCSI IO card, which comes with short range (SR) SFP+ transceiver modules.Figure 13. SFP+ Transceiver Module with a Bail Clasp LatchThe SFP+ transceiver modules are inserted into the ports of the 10Gb iSCSI IO card in the SC4020. Fiber-optic cables are then connected from the SFP+ transceiver modules in the SC4020 to SFP+ transceiver modules in enterprise-class switches.Connect the Front End23Guidelines for Using SFP+ Transceiver ModulesThe SC4020 storage controller supports the use of small-form-factor pluggable (SFP+) transceiver modules for 10GbE iSCSI connectivity.Before installing SFP+ transceiver modules and fiber-optic cables, read the following guidelines:CAUTION: When handling static-sensitive devices, take precautions to avoid damaging theproduct from static electricity.•Use only Dell supported SFP+ transceiver modules with the SC4020. Other generic SFP+ transceiver modules are not supported and may not work with the SC4020.•The SFP+ transceiver module housing has an integral guide key that is designed to prevent you from inserting the transceiver module incorrectly.•Use minimal pressure when inserting an SFP+ transceiver module into an iSCSI port. Forcing the SFP+ transceiver module into a port may damage the transceiver module or the port.•The SFP+ transceiver module must be installed into a port before you connect the fiber-optic cable.•The fiber-optic cable must be removed from the SFP+ transceiver module before you remove the transceiver module from the port.Cleaning Fiber-Optic PortsCleaning fiber-optic ports is an important requirement for maintaining quality connections between fiber-optic equipment. Any contamination in the fiber connection can result in degraded performance or communication failures.Micro-deposits of oil and dust on the fiber-optic ports of the transceiver modules or fiber-optic cable connectors can cause loss of light, reduction in signal power, and possibly intermittent problems with the optical connection.To avoid problems with connections between fiber-optic equipment, Dell recommends that you clean the fiber-optic ports and connectors each time you make a connection.NOTE: When you are not using a transceiver module or fiber-optic cable, always install protective covers to prevent contamination.Cleaning SFP+ Transceiver ModulesDell recommends using a can of compressed air to clean the fiber-optic ports of SFP+ transceiver modules.Prerequisites•Handle the SFP+ transceiver module in an ESD safe environment using the proper safety precautions.•Make sure that the can of compressed air is approved for cleaning fibre optics.•Make sure that the can of compressed air has a straw inserted into the nozzle.Steps1.Spray the can of compressed air for 3–5 seconds to make sure that any liquid propellant is expelledfrom the straw.2.Align a fiber-optic port of the transceiver module with the straw on the can of compressed air.Hold the transceiver module near the end of the straw, but do not touch the inner surfaces of the module.24Connect the Front End3.Hold the can of compressed air upright and level with the transceiver module.CAUTION: Tipping the can of compressed air may release liquids in the air stream.e the can of compressed air to blow out particles from the inside of the transceiver module.5.Examine the optical surface of the connector using high intensity light and a magnifying tool.If contaminants still exist, repeat the cleaning process.6.Immediately install the protective dust cover into the transceiver module to avoid recontamination.Keep the protective cover in the transceiver module until you are ready to connect it to a fibre optic cable.Cleaning Fiber-Optic Cable ConnectorsDell recommends using a can of compressed air, methanol or isopropyl alcohol, and a lens tissue to clean fiber-optic cable connectors.Prerequisites•Do not allow the end of the fiber-optic cable to contact any surface, including your fingers.•Make sure that the can of compressed air is approved for cleaning fibre optics•Make sure that the can of compressed air has a straw inserted into the nozzle.•Only use fresh (dry) spectroscopic grade methanol or isopropyl alcohol as a cleaning solvent.•Only use lens tissues with long fibers and a low ash content type that has no chemical additives. Steps1.Spray the can of compressed air for 3–5 seconds to make sure that any liquid propellant is expelledfrom the straw.2.Hold the can of compressed air upright and level with the fiber-optic cable connector.CAUTION: Tipping the can of compressed air may release liquids in the air stream.e the can of compressed air to blow particles off the surface of the fiber-optic cable connector.4.Place 2–3 drops of the methanol or isopropyl alcohol on a lens tissue.5.Place the wet portion of the lens tissue on the optical surface of the fiber-optic cable connector andslowly drag it across.6.Examine the optical surface of the fiber-optic cable connector using high intensity light and amagnifying tool.If streaks or contaminants still exist, repeat the cleaning process using a fresh lens tissue.7.Immediately install the protective dust cover over the end of the cable to avoid recontamination.Keep the protective cover on the end of the cable until you are ready to connect it.Install an SFP+ Transceiver ModuleComplete the following steps to install an SFP+ transceiver module in a 10Gb iSCSI IO card.About this taskRead the following cautions and information before installing an SFP+ transceiver module.WARNING: To reduce the risk of injury from laser radiation or damage to the equipment, observe the following precautions:•Do not open any panels, operate controls, make adjustments, or perform procedures to a laser device other than those specified herein.•Do not stare into the laser beam.Connect the Front End25。
