  • Page 14 Chapter 1 - Getting Started At a Glance The following illustrations show the featured components of the OmniStor 4700S Series RAID Storage System. Familiarize yourself with its components prior to installing and using the storage system. Hot-pluggable power supply (AC PSU is shown)

  • Page 15: Components

    Chapter 1 - Getting Started Components This section provides a description of each of the major components that comprise the OmniStor 4700S Series RAID Storage System. 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.

  • Page 16: Power System

    Chapter 1 - Getting Started Power System The single or dual power supply configuration is determined at boot up. If at boot up, only one power supply is detected, then the single power supply configuration is set. If two power supplies are detected, then the dual power supply configuration is set. Standard AC Hot Swappable Power Supplies The AC power system is designed to support two 350-watt hot-pluggable power supplies, each with independent AC power cords and cooling fans.

  • Page 17: Optional Dc Hot Swappable Power Supplies

    Chapter 1 - Getting Started When the dual power supply configuration is set at boot up, the front bezels’ Power Supply Status LED will illuminate green when both power supplies are on and operating normally. If only one power supply is operational, the Power Supply Status LED will be illuminated amber.
  • Page 18 Chapter 1 - Getting Started If the power supply cooling fan fails, the Fault LED will illuminate and the alarm will sound. The power supply also has an amber general Fault LED. If you have a dual power supply configuration and power is not applied to one of the power supplies, the general Fault LED is illuminated.

  • Page 19: Cooling Fan Module

    Chapter 1 - Getting Started Power supply overload protection will shut down the power supply when the output power rating exceeds 110% to 130% of maximum rated output current. DC Supply and Ground The DC supply and ground conductor must meet the following requirements: Suitable conductor material: copper only.
  • Page 20 Chapter 1 - Getting Started Fan Speed Override Contr ol Jumpers JP1 (Fan 0) and JP2 (Fan 1) Cooling Fan Module The enclosure has temperature sensors in three different areas, the drive bay, the RAID Controller, and the power supplies. There are several steps the storage system performs to prevent component damage due to over temperature conditions.
  • Page 21 Chapter 1 - Getting Started Normally, the fan speed is controlled automatically by the SAF-TE process. It will maintain fan RPM at the minimum required to maintain effective cooling. Should a condition occur that requires a greater volume of air, the fan RPM will increase up to the maximum to maintain cooling temperatures.

  • Page 22: Raid Controller

    Chapter 1 - Getting Started RAID Controller The OmniStor 4700S Series RAID Storage System is designed with one SCSI-to-Serial ATA RAID Controller. The controller supports RAID levels 0, 1, 5, 10, and 50. The SCSI-SATA RAID Controller is designed for low cost high capacity and high performance applications.

  • Page 23: Automatic Termination Override

    Chapter 1 - Getting Started The controller face plate has Activity and Status LEDs. Refer to the illustration below for descriptions of each LED. CH 0 SCSI-SATA RAID Controller Face Plate LEDs Description Automatic Termination Override To ensure proper SCSI termination when daisy-chaining OmniStor 4700S storage systems, you will be required to override the automatic termination feature on the enclosures that are not at the end of the SCSI bus chain.
  • Page 24 Chapter 1 - Getting Started In a Expansion Connection configuration (daisy-chain), enclosures are cabled to each other up to a maximum of three (3) enclosures. Since the RAID Controller is not supplying the term power, a manual override is provided through the switches. This is due to a logical condition where termination is disabled when a cable is sensed plugged into the connector.

  • Page 25: Battery Backup Unit

    Chapter 1 - Getting Started Battery Backup Unit The main board of the SCSI-SATA RAID Controller includes battery control circuitry for a single cell Lithium Ion battery along with a battery pack mating connector. The main purpose of battery backup is to maintain the cache memory during brief power interruptions, but is capable of maintaining the memory content for several hours, depending on the type and size of the memory.

  • Page 26: Embedded Saf-Te Support

    Chapter 1 - Getting Started Embedded SAF-TE Support The SCSI-SATA RAID Controller implements the SAF-TE Interface protocol for monitoring enclosure environmental conditions. This is accomplished through the controller firmware and is known as “SAF-TE processes.” SAF-TE protocol provides the interface specification for monitoring enclosure component status and reporting environmental condition data on the enclosure’s temperature, fan status, power supply status, and bus status.

  • Page 27: Control And Monitoring

    Chapter 1 - Getting Started Control and Monitoring An integral part of the OmniStor 4700S Series RAID Storage System is its control and monitor capabilities. The monitored data for the enclosure environmental conditions such as enclosure temperature, cooling fan status, power supply status, and SCSI bus status is displayed in the VT-100 Enclosure Information menu item.

  • Page 28: Power-On Led

    Chapter 1 - Getting Started Power-On LED The Power-On LED signifies that the enclosure is powered on and will be illuminated green when power has been applied. Channel Status LED The Channel Status LED will illuminate green to indicate a valid status of the SCSI bus and the logical arrays.

    Chapter 2 Operating Mode and Topologies This chapter provides an overview of the operating mode and topologies supported by the OmniStor 4700S. Understanding the topologies allows you to make the best choice for the optimum configuration that completes your storage system solution. Simplex Mode The simplex operating mode uses the single SCSI-SATA RAID Controller providing the storage solution with some level of redundancy.

    Chapter 2 - Operating Mode and Topologies Clustered Connection - Dual Hosts This topology supports standard current SCSI clustering infra-structure. Each host employs a single ported SCSI HBA. Each SCSI bus is isolated and the LUNs are viewable on both SCSI ports.

  • Page 32: A Word About Clustering

    Chapter 2 - Operating Mode and Topologies This redirection is known as path failover. The software continuously tries to access the failed path by issuing a SCSI Test Unit Ready command. A good status returned indicates the path is repaired and restored to operational status. The software automatically redirects data back to the primary path and primary disk object.
  • Page 33 Chapter 2 - Operating Mode and Topologies Availability figures relate primarily to unplanned downtime. But the advantages of clusters in terms of planned or scheduled downtime are even more significant. Planned downtime requires shutting down stand-alone systems entirely. Result: 100% loss of processing for the duration of the downtime.
