Overview
2 Hardware The HP StorageWorks 200 Storage Virtualization System provides high-performance management of up to 127 TB of heterogeneous storage. There are no single points of failure in the system. It includes redundant data and control paths and redundant power supplies.
The following figure shows the rack with Controller and control panel.
Item Component Description 1 Front view Front view of rack with cabinet open 2 HP SVS200 Controller Controller, including modules, control panel, and Service Processor PC (SVP) 3 Second Controller space Space where a second factory-installed SVS200 Controller resides if you ordered a second unit with this rack. 4 Control panel Operational controls (described later) CAUTION: The HP SVS200 has no user-serviceable components. Only an HP support representative should open the cabinet.
Controller The Controller resides in the equipment rack and contains the control panel, circuit boards, power supplies, and SVP. Your HP representative will help you install the system and make connections from the Controller to hosts, storage systems, networks, and power. Control panel Once the system is powered on and running normally, no user operations are required at the control panel, except when instructed by your HP support representative. The following figure and table describe the control panel.
Item Label Indicator Description 1 READY LED (Green) During normal operation, this LED should be on. ON: Input/output on the channel interface is enabled. OFF: The system is not accepting data. 2 ALARM LED (Red) During normal operation, this LED should be off. ON: One or more of the following: The DC is under voltage. The DC is over current. The temperature is abnormally high. An unrecoverable failure has occurred.
Item Label Indicator Description 4 RESTART Switch If a blocked path occurs between a host and a disk drive, this switch is used to unfence the fenced drive path and to release Write Inhibit. During normal operation, this switch should be in the upper position. Restarting the system performs a soft reset to try to recover. If the system restart does not unblock the path, an HP support representative will be notified.
Item Label Indicator Description 8 PS-ON LED (Green) During normal operation, this LED should be on. ON: The PS ON/OFF switch is on. If the READY light is also on, the system is ready to receive data. OFF: The PS ON/OFF switch is off and the system is not ready to receive data. 9 PS ENABLE Switch Used to enable the PS ON/OFF switch. During normal operation, this switch should be in the “Disable” position (opposite the ENABLE position). ENABLE: The PS ON/OFF switch can be used.
Service processor (SVP) The Service Processor inside the controller performs these functions: • Collects performance data on the system for diagnostic testing and analysis • Provides your HP support representative with access to the system • Hosts system management software Your HP support representative uses the SVP to configure, maintain, and upgrade the system software and hardware. The SVP is not a customer-accessible component.
Backup batteries Internal batteries provide backup power for the cache memory, shared memory, and the CHIPs. The backup batteries enable the system to continue normal operations for up to 20 milliseconds after the loss of AC power. When AC power is off longer than 20 milliseconds, the system executes its backup process. This process copies the contents of cache and shared memory to storage and then supports cache and shared memory for up to 36 hours.
System and storage management HP Remote Web Console gives you browser-based control and management of the system from a remote Windows client you supply. Additionally, to manage storage systems, you must install the Command View Advanced Edition software on a Windows Device Manager server you supply. Other HP StorageWorks software may also be installed on this host, including the supplied External Storage and Tiered Storage Manager applications that enable you to optimize use of your tiered storage systems.
Operating specifications This section provides some general specifications. For complete specifications, see the system site preparation guide, available on the HP XP Disk Array web site: http://h18006.www1.hp.com/storage/xparrays.html.
Humidity Protect the system from excessive humidity. You should not observe condensation in or around the product under any conditions.
AC line voltage requirements This section lists the AC power recommendations. The rack has four power cords, but only the lower two are used for the controller. The upper two power cords are reserved for an optional second controller. In case of a failure of the power source for one cord, the power requirements, and therefore the current requirement for the remaining power cord, will double.
Hardware
3 Operations During normal operations, the system does not require your intervention and you should not attempt to open the system cabinets. The system reports any service information messages (SIMs) to the SVP and the Device Manager server. If the array is set up to “phone home,” the SVP automatically reports SIMs to the HP Storage Technology Center (STC). For more information on SIMs, see Service information messages.
General safety guidelines Carefully read these safety guidelines and follow them when working with the system. • Fully understand and follow all hazard warnings in this guide and on warning labels on the system. These hazard warnings help you to prevent or reduce the risk of death, personal injury, or product damage.
CAUTION: If you detect any abnormal noise, smell, or smoke coming from the system, immediately power off the system by following the emergency power off procedure later in this chapter. For routine power off in non-emergency situations, contact your HP support representative. CAUTION: Keep the front and rear doors closed at all times. CAUTION: Keep the tops and sides of the cabinets clear to allow air to flow properly. CAUTION: Use the supplied power cord.
Powering down the system Two situations may arise when you need to power down the system: • Emergency power off • Planned power off For instructions in each of these situations, see the following procedures. Emergency power off The system does not have an emergency power off switch. In an emergency when it is crucial to power off the system immediately for safety reasons, remove power at the AC branch circuit breakers in your facility that supply power to the system.
Planned power off Occasionally, you may need to plan a site power outage, such as during alterations to the data center, inspections, or work by the electric company. If a scheduled power outage will affect the system, contact your HP support representative to schedule a planned power off. CAUTION: Only a trained HP support representative can shut down and power off the system. Do not attempt to power down the system other than during an emergency.
Recovering from an unplanned or emergency power outage Unplanned power outages occur when the primary building power is lost due to electrical blackouts, thunderstorm activity, or similar occurrences, and input AC power is not received by the system. The system will maintain its state and recover when power is restored. The system cache is powered by backup batteries that will maintain the system state for up to 36 hours, depending on the selected battery operation mode.
CAUTION: Power on can take several minutes and is not complete until the READY LED turns green. 3. Move the PS ENABLE switch to “DISABLE” (opposite the ENABLE position).
Automatic restart when power is restored CAUTION: HP recommends the use of automatic power on restart only if the power to the system is subject to power conditioning equipment, such as a UPS, to ensure that the power restored to the system is stable. If your site does not have a UPS, HP recommends configuring the system for manual restart, meaning the Auto-Power-On jumper, which is set during installation by an HP support representative, is in the DISABLE position.
