Chapter 2 Theory of Controller Operation This chapter provides a functional overview and understanding of the supported topologies and operating modes for the NexStor 4000S/4100S Series Storage System. With this information, you will be able to make the best choice based on the supported topologies, to set up your storage solution.
Page 34
Chapter 2 - Theory of Controller Operation Stand-Alone Dual Port – Use this mode when you have a NexStor 4110S (single RAID controller) and require dual-HBA host access, or two independent host access. There will be several cabling schemes to choose from when you setup this operating mode.
Chapter 2 - Theory of Controller Operation Stand-Alone Mode In Stand-Alone mode, the RAID controller operates autonomously. The controller has two SCSI Host I/O connector ports. They are labeled in the diagrams as “CH 0” and “CH 3.” In Single Port mode, the “CH 3” connector becomes a drive channel providing one additional drive channel for expansion.

Chapter 2 - Theory of Controller Operation Active-Active Mode In the Active-Active mode, the two RAID controllers cooperate to provide redundancy. If one controller fails, the remaining controller will take over the failed controller’s functionality. Each controller has two SCSI Host ports, they are labeled in the diagrams as “CH 0”...
Page 39
Chapter 2 - Theory of Controller Operation After killing the other controller, it will take ownership of the arrays and will activate its passive host port to assume the defunct controller’s identity. The following diagrams illustrate the logical function of the controllers when both are active and then again when one controller has failed.
Page 40
Chapter 2 - Theory of Controller Operation In the failed-over condition, the active controller will present its native identity on one Host port, and the failed-over controller’s identity on its other Host port. After the controller has failed-over, the user can replace the failed controller with a new controller, and the arrays will fail-back to the new controller without intervention.
Chapter 2 - Theory of Controller Operation Active-Passive Mode In the Active-Passive mode, there is one active and one passive RAID controller. The primary (active) controller operates with both of its Host ports enabled and presents all LUNs on both ports to maximize bandwidth. The secondary (passive) controller keeps both its Host ports passive, and does not service any LUNs.
Page 42
Chapter 2 - Theory of Controller Operation Advantages: Transparent fail-over and fail-back. Single point of failure is the host system. (There are no single points of failure when dual host systems are configured with clustering software.) Upstream fail-over. Disadvantages: Lower performance than the Active-Active mode. Upstream fail-over requires third party software.
Chapter 2 - Theory of Controller Operation Understanding Mirrored Operations The mirroring feature causes configuration changes to be mirrored to the opposite controller in an Active-Active configuration. The mirrored configuration is stored in the other controller’s firmware (Flash). If a controller fails and is replaced, then on boot up, it attempts to retrieve this configuration data from the opposite controller.
Chapter 2 - Theory of Controller Operation A Word about Clustering Minimizing Downtime for Maximum Data Availability So-called open systems, such as Windows NT servers, just don’t provide the level of availability that IS managers are familiar with on mainframes. A partial solution to this problem is server clustering.
Page 45
Chapter 2 - Theory of Controller Operation High availability is not the only benefit of clustering. In some cases, users may see advantages in the areas of performance, scalability, and manageability. In reality, you can expect a 1.6x (80% efficiency) to 1.8x (90% efficiency) performance increase as you go from one node to two nodes.
Chapter 2 - Theory of Controller Operation How Available are Clusters? The following tables outlines the maximum availability per downtime in the different architectures: Architecture Maximum Availability Downtime per Failure Downtime per Year (in minutes) Continuous 100.00% None Processing Fault-Tolerant 99.9999% Cycles 0.5 - 5...

Chapter 5 - Monitoring Systems Enclosure Fan Speed Control The SAF-TE Disk I/O or SCSI SAF-TE Cluster card has a firmware-based VT-100 interface which provides an option for fan speed control. This allows the user with the choice to enable or disable the automatic control feature. It provides for more efficient management of the cooling fans and a whisper mode fan operation for noise sensitive environments where it significantly reduces the noise created by the cooling fans running constantly at full speed.
Page 118
Chapter 5 - Monitoring Systems This hardware setting provides full voltage to the fans for maximum operational speed, which is greater than the maximum speed set by the automatic software control. This configuration is normally used when fan speed noises are not an issue, and the ambient operating temperature is at or above 30°C (86°F), thus ensuring that maximum available cooling is being provided.
