Chapter 1 - Getting Started At a Glance The following illustrations show the featured components of the NexStor 4100FS Series Storage System. Familiarize yourself with its components prior to installing and using the storage system. Drive Status LEDs (left column of LEDs)
Chapter 1 - Getting Started Components This section provides a descriptive overview of each of the major components that comprise the NexStor 4100FS Storage System enclosure. Front Bezel The front bezel houses the Status LEDs, Drive LEDs, and alarm reset button. When removed, the user has access to the disk drives.
Chapter 1 - Getting Started AC Power The power system consists of two 350-watt hot-pluggable power supplies, each with independent AC power cords and cooling fans providing the enclosure with “N+1” redundant power. Each power supply has auto-switching circuitry for use with either 100V or 240V AC systems.
JP2 (Fan 1) Cooling Fan Module The NexStor 4100FS Storage System monitors temperature in three different areas, the drive bay, the RAID Controllers, and the power supplies. There are several steps the storage system performs to prevent component damage due to over temperature conditions.
Page 18
Chapter 1 - Getting Started If the drive bay area reaches a temperature of 50°C (122°F) an audible alarm will sound, the front panel Fan Status LED will toggle amber green, and the monitoring software will post a warning message. These notifications give the user a warning that some condition is causing the enclosure temperature to exceed the preset value, and an action is required by the user to determine the cause and take corrective measures.
Chapter 1 - Getting Started SAF-TE Disk I/O Card WARNING: The SAF-TE Disk I/O card is NOT HOT SWAPPABLE. You must POWER DOWN the enclosure prior to removing or installing this card. The SAF-TE Disk I/O card provides the built-in environmental and system status monitoring, as well as, host connectivity to the disk drives, It also houses the switches for setting SCSI IDs, VT-100 communication protocols, and drive spin up options.
Page 20
Chapter 1 - Getting Started The SAF-TE Disk I/O card has two 68-pin VHD/CI SCSI connectors which provides the daisy-chain drive connectivity to the expansion JBOD enclosures. The connectors are labeled “Channel 1” and “Channel 2.” NOTE: Termination is automatic and provided internally on the drive mid-plane circuit board.
Chapter 1 - Getting Started Host SCSI I/O Card WARNING: The Host SCSI I/O card is NOT HOT SWAPPABLE. You must POWER DOWN the enclosure prior to removing or installing this card. The Host SCSI I/O card is installed to provide the Channel 0 and Channel 3 SCSI drive ports.
Chapter 1 - Getting Started Fibre Channel Host I/O Card WARNING: The Fibre Channel Host I/O card is NOT HOT SWAPPABLE. You must POWER DOWN the enclosure prior to removing or installing this card. The Fibre Channel Host I/O card provides the four host ports configured with internal active hubs and Small Form Factor Pluggable (SFP) module cages for connectivity from the host computer (server) to each RAID controller.
Chapter 1 - Getting Started RAID Controllers The enclosure houses one or two RAID Controllers. It supports configurations for single controller Stand-Alone topologies and dual controller Active-Active/ Active-Passive topologies. The RAID Controller is a Fibre Channel-to-Ultra160 SCSI RAID controller. It has four 2 Gb Fibre Channel host ports and four Ultra160 SCSI disk channel ports.
Page 24
Chapter 1 - Getting Started Optical SFP Transceiver The Fibre Channel Host I/O card uses a hot-swappable Small Form-Factor Pluggable (SFP) transceiver. The optical transceiver provides operations up to 2.5 Gb per second. The transceiver includes a lost signal detect circuit which provides TTL logic high output when an unusable input signal is detected.

Chapter 1 - Getting Started Control and Monitoring An integral part of the NexStor 4100FS Series enclosures is its control and monitor capabilities. The SAF-TE processors provide monitoring data for the enclosure environmental conditions such as enclosure temperature, cooling fans, power supplies, and SCSI bus status.
Chapter 1 - Getting Started Status Indicator LEDs The Status Indicator LEDs comprise the Power-On LED, Channel Status LED, Power Supply Status LED, and Fan Status LED. These series of LEDs are grouped on the right side of the front bezel directly above the Alarm Reset button. The following is an description of each of these LEDs.
Chapter 1 - Getting Started Audible Alarm An audible alarm will sound when any of the enclosure’s component condition changes to an abnormal state. To silence the alarm, press the Alarm Reset button located on the front bezel. The corresponding alarms’ LED will remain illuminated until the condition returns to a normal state.

With this information, you will be able to make the best choice based on the supported topologies, to set up your storage solution. There are three operating modes available for the NexStor 4100FS Series: Stand- Alone, Active-Active, and Active-Passive. The NexStor 4110FS model with its single...
Page 32
(NexStor 4120FS) Another consideration when selecting one of these topologies is whether you will enable or disable the internal hubs. Each NexStor 4100FS Series Storage System enclosure has built-in internal hubs. These internal hubs, when enabled, essentially replace the need for external hub hardware. They provide for up to four (4) host connections.
Chapter 2 - Theory of Controller Operation Stand-Alone Mode In Stand-Alone mode, the RAID Controller operates autonomously. The controller has two Fibre Channel (FC) Host ports, which are labeled in the diagrams as “FC1” and “FC2.” This operating mode uses both FC host ports. Advantages: Low cost entry-level RAID storage solution that is field upgradeable.

Page 38
Chapter 2 - Theory of Controller Operation In the failed-over condition, the active controller will present its native identity on one FC Host port, and the failed-over controller’s identity on the other port. This is slightly different when using a dual port configuration, where each array is presented on both FC Host ports.
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 FC Host ports enabled and presents all LUNs on both ports to maximize bandwidth. The secondary (passive) controller keeps both its FC Host ports passive, and does not service any LUNs.
Page 40
Chapter 2 - Theory of Controller Operation Careful administration is necessary, since all the arrays are reported twice to the host operating system which requires the use of third party file share/file lock software to prevent data overwrites. Controller FC Host Ports Drive I/O Connectors RAID Controller HOST I/O...
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 43
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.

Upgrades At some point you may have a need to upgrade your storage system to increase the storage capacities and/or the RAID capabilities. The NexStor 4100FS Series Storage System provides you with this ability to meet your expanding data storage requirements.
Ensure that none of the data cables or power cables are obstructing the air flow exiting the cooling fan module. Locate the power supply On/Off switches at the rear of the NexStor 4100FS Series Storage System enclosure(s). Press each power supply switch to its “On” position. (Repeat this step for each of the attached storage system enclosure(s).)
Chapter 4 SAN Solution Strategies This chapter will describe connecting the NexStor 4120FS Series Storage Systems providing an Active-Active/Active-Passive solution to a Storage Area Network (SAN). Active-Active:Dual Port Mode for SAN At the heart of this strategy is the Active-Active Dual Port operating mode. In this mode, four Fibre Channel (FC) ports are simultaneously active when both controllers are online.
Page 84
Chapter 4 - SAN Solution Strategies Hubs Enabled In the following illustrations, the controllers are configured in an Active-Active Dual Port mode with the internal hubs enabled. In the example below, two hosts are connected via two independent loops using the enclosure’s built-in hub bypass circuits.
Page 85
Chapter 4 - SAN Solution Strategies This example illustrates the conditions when Controller 2 fails. Note that both hosts can still see Controller 1’s LUNs (LUN 1) and Controller 2’s LUNS (LUN 2). However, each host HBA can only see one LUN, instead of both. CH 1 CH 2 CH 0...
Page 86
Chapter 4 - SAN Solution Strategies Hubs Disabled In the following illustrations, the two controllers are configured in an Active-Active Dual Port mode with the internal hubs disabled. In the example below, two hosts are connected via two independent switches. Using external switches supports higher bandwidth, since the host ports are not required to share bandwidth on a loop.
Page 87
Chapter 4 - SAN Solution Strategies In this example, two hosts are connected via two independent switches. Note that both hosts can still see Controller 1’s LUNs (LUN 1) and Controller 2’s LUNs (LUN 2). However, each host HBA can only see one LUN, instead of both. CH 1 CH 2 CH 0...
Chapter 4 - SAN Solution Strategies Active-Active:Single Port Mode for SAN There are several scenarios where it may be desirable to configure the controllers in Active-Active Single Port mode. In general, these are situations where the hosts have a single Fibre Channel port, and so the SAN is not truly fault-tolerant. Hubs Disabled (Single Port Hosts and One Switch) The following illustration depicts two single ported hosts connected to the two controllers via a single switch.
Page 89
Chapter 4 - SAN Solution Strategies In this case, there would be an advantage to configuring the controllers in Active-Active Dual Port mode, because of increased connectivity. However, the host driver software would need to handle the fact that each LUN would appear twice in the SAN fabric, and that one image of the LUNs would disappear if one controller failed.
Page 90
Chapter 4 - SAN Solution Strategies Hubs Disabled (Single External Hub) The following illustration depicts the hosts in a single loop configuration using an external hub. When a controller failover occurs, this configuration operates much the same as the previous one which uses a switch. The advantage is that a hub is less expensive.
Page 91
Chapter 4 - SAN Solution Strategies Hubs Enabled The illustration below depicts hosts in a single loop configuration with the internal hubs enabled. The internal hubs eliminate the need for an external hub. It allows one or two hosts to be connected to the Active-Active storage enclosure without the cost of external hardware other than cables.
Chapter 4 - SAN Solution Strategies SAN Configuration Not Supported In the Active-Active:Dual Port configuration with two independent hubs or the internal hubs, two single-ported hosts is not supported. The issue with this configuration is that if a controller fails, each host loses access to one of the LUNs. For example, if Controller 1 fails, Host 1 can no longer access LUN 2, because Port 2 on Controller 2 has changed from presenting its own LUNs to presenting Controller 1’s LUNs.
Chapter 5 Accessing the RAID Controllers There are two types of software user interfaces provided to access, configure and manage the RAID Controllers; they are AdminiStor Storage Management software and the controller’s onboard Disk Array Administrator software. AdminiStor is a HTML/Java application that provides a GUI interface through a standard web browser for configuration and management of the disk arrays.
Chapter 5 - Accessing the RAID Controllers Accessing the Disk Array Administrator Software/VT-100 You gain access to the RAID Controller onboard Disk Array Administrator software through a VT-100 terminal connected to one of the RS-232 controller service ports located at the rear of the enclosure. You must use a null-modem serial cable to connect the terminal to either the Controller 1 (CTRL 1) or Controller 2 (CTRL 2) service ports.

You can safely stop the transfer without affecting your existing firmware any time during the transfer until it has been completed.
Chapter 6 Monitoring Systems In this chapter you will find information about using the enclosure’s onboard monitoring systems. Also you will find procedures to update the enclosure’s SAF-TE Disk I/O card firmware. Using a VT-100 terminal (or emulation), the SAF-TE Service port provides an interface to the enclosure’s monitoring system and firmware.
Chapter 6 - Monitoring Systems Status Indicator LEDs The Status Indicator LEDs located above the Alarm Reset button, comprise the Power-On LED, Channel Status LED, Power Supply Status LED, and Fan Status LED. The following are descriptions of each of the LEDs. Power-On LED The Power-On LED signifies that the enclosure is powered on and will be illuminated green when power has been applied.

Chapter 6 - Monitoring Systems Enclosure Fan Speed Control The SAF-TE Disk I/O 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.
