Controller Modules2RAID Controller ModulesThe RAID controller modules provide high-performance, advanced virtual disk configuration, and faulttolerant disk subsystem management. Each RAID controller module contains 4GB or 8GB of mirroredcache for high availability and a battery-powered cache offload mechanism.NOTE: The 8GB mirrored cache is an optional feature.RAID controller modules provide the following data path and enclosure management functions: Monitoring and controlling enclosure environment elements (temperature, fans, power supplies, andenclosure LEDs) Controlling access to the physical disks Communicating enclosure attributes and states to the host server and management stationEach RAID controller module has multiple Fibre Channel (FC) ports (labeled FC IN) for host access. Theports provide redundant host connections and support a high availability storage environment. Each portmust have a small form-factor pluggable (SFP) transceiver module installed for connectivity. Variousconfigurations can be utilized, in both single controller (simplex) and dual controller (duplex) modes, toconnect the storage enclosure to hosts depending on specific redundancy needs.For information on cabling, see the MD3800f and MD3820f Series Storage Arrays Deployment Guide, atdell.com/powervaultmanuals.RAID Controller Module Connectors and FeaturesFigure 7.

The status of any FC port can be determined by applyingthe following table to the condition of each LED pair.Table 5. Host Channel LED Link Rate IndicationsLED 1LED 0CommRateOffOffLink downOffOn2 GbpsOnOff4 GbpsOnOn8 GbpsRAID Controller Module—Additional FeaturesBattery Backup UnitEach RAID controller contains a two-cell Lithium ion nanopolymer battery backup unit (BBU). It providespower to the RAID controller module in the event of a power outage. For information on removing andinstalling the BBU, see RAID Controller Module Backup Battery Unit .NOTE: For virtual disks, the RAID controller firmware changes the data cache setting based on thestate of the battery. If the battery is missing or does not have sufficient charge, the controller flushesthe cache and sets the write cache attribute to Write Through for all virtual disks. When the batteryis replaced, Write Back is re-enabled.Storage Array Thermal ShutdownThe system automatically shuts down when system temperature exceeds the safe threshold. The batterybackup unit protects against data loss by providing power to offload cache to non-volatile memory in theevent of power loss. It is not necessary to shut down any MD1200 Series expansion enclosures attachedto the storage array when thermal shutdown occurs.14
Temperature threshold values determine the temperature at which shutdown occurs. These thresholdscannot be changed.Table 6. Shutdown Threshold TypeThreshold Temperature ExceedingEvent DescriptionNominal failure thresholdA critical event is set.Maximum failure thresholdShutdown of the system power suppliesoccurs within 3 minutes.Shutdown thresholdShutdown of the system power suppliesoccurs within 5 seconds.System Password ResetThe storage array password can be reset if it is forgotten. To reset the password, push and hold down thepassword reset switch for at least 5 seconds. The password is deleted.The RAID controller module allows you to change the password.NOTE: The reset switch can be accessed by using a small object such as the tip of a pen.NOTE: The password reset switch is not available if your system was shipped after September, 2015.The password reset switch functionality was disabled starting from controller firmware 08.20.09.60and later versions.Cache Functions and FeaturesCache MirroringCache mirroring function copies accepted host-write data from the primary controller to the partnercontroller. This action ensures that host-write data is safely mirrored to the partner controller beforesuccessful completion status is returned to the host. If a controller fails, the surviving controller safelyretains all mirrored data. Cache mirroring is enabled by default.Write-Back CacheIn write-back cache, write operations result in a completion signal being sent to the host operatingsystem as soon as the cache receives the data to be written. The target physical disk receives the data at amore appropriate time to increase controller performance. In dual-active controller configurations withwrite-back caching enabled, the write data is always mirrored to the cache of the second controllerbefore completion status is issued to the host initiator. Write-back cache is enabled by default unlesscache mirroring is disabled.Write-Through CacheIn write-through cache, data is written to the physical disk before completion status is returned to thehost operating system. Write-through cache is considered more robust than write-back cache, since a15
power failure is less likely to cause loss of data. The RAID controller automatically switches to writethrough if cache mirroring is disabled, or if the battery is missing, or has a fault condition.SFP Transceivers, Fiber Optic, and SAS CablesFC host connections may operate at 16 Gbps or at a lower data rate. Ports for 16 Gbps FC hostconnections require SFP transceivers designed for this data rate. SFP transceivers that support other datarates are incompatible.WARNING: Do not disassemble or remove any part of a small form-factor pluggable (SFP)transceiver due to the possibility of being exposed to laser radiation.NOTE: Your SFP transceivers and cables may look different from the ones shown below. Thedifferences do not affect the performance of the SFP transceivers.Figure 8.

Interoperability of 4 Gbps, 8 Gbps, and 16 Gbps DevicesThe FC standard specifies a procedure for speedy autodetection. If an 8 Gbps port on a switch or deviceis connected to a 4 Gbps port, it must negotiate down for the link to run at 4 Gbps. If there are two 16Gbps ports on either end of a link, the negotiation runs the link at 16 Gbps if the link supports the requiredspecifications. If a link connects at 8 Gbps in this scenario, possible causes could be excessive cablelength, poor cable quality, loose cables or SFPs, and so on. Ensure that the cable lengths are notexcessive and the quality of the cable and connector is good.17
