If this LED is off, it indicates that no fault condition is present. 3 AC power The LED lights green when the AC input voltage is within the limit.
Controller Modules 2 RAID Controller Modules The RAID controller modules provide high-performance, advanced virtual disk configuration, and faulttolerant disk subsystem management. Each RAID controller module contains 4GB or 8GB of mirrored cache for high availability and a battery-powered cache offload mechanism. NOTE: The 8GB mirrored cache is an optional feature.
Item Component Function 1 16 Gbps FC IN port (4) Provides host-to-controller FC connection. 2 Seven segment display sequence Displays status or error codes for the storage array. 3 Controller power LED Lights green when controller power is on. Turns off when controller is not powered. 4 Controller fault LED Lights amber when controller fault is detected.
RAID Controller Module—Additional Features Battery Backup Unit Each RAID controller contains a two-cell Lithium ion nanopolymer battery backup unit (BBU). It provides power to the RAID controller module in the event of a power outage. For information on removing and installing the BBU, see RAID Controller Module Backup Battery Unit . NOTE: For virtual disks, the RAID controller firmware changes the data cache setting based on the state of the battery.
Write-Back Cache In write-back cache, write operations result in a completion signal being sent to the host operating system as soon as the cache receives the data to be written. The target physical disk receives the data at a more appropriate time to increase controller performance. In dual-active controller configurations with write-back caching enabled, the write data is always mirrored to the cache of the second controller before completion status is issued to the host initiator.
Figure 9. SAS Cable 1. 3. mini SAS connector mini SAS HD connector 2. SAS cable Interoperability of 4 Gbps, 8 Gbps, and 16 Gbps Devices The FC standard specifies a procedure for speedy autodetection. If an 8 Gbps port on a switch or device is connected to a 4 Gbps port, it must negotiate down for the link to run at 4 Gbps. If there are two 16 Gbps ports on either end of a link, the negotiation runs the link at 16 Gbps if the link supports the required specifications.
