Product Overview of the HP 512735-001 Cache Controller Battery
The HP 512735-001 is a specialized battery unit designed specifically as a cache controller battery for EVA (Enterprise Virtual Array) systems, specifically compatible with EVA 4000, 6000, and 8000 series. This battery plays a crucial role in ensuring data integrity and system reliability within these storage arrays.
Purpose of the Cache Controller Battery
The cache controller battery serves as a backup power source for the storage array's cache memory. Cache memory is a high-speed volatile memory used for temporarily storing data before it's written to or retrieved from the storage disks. This battery acts as a safeguard, preserving the cached data in case of a power outage or system failure.
Understanding the Technical Specifications
Voltage and Amperage
- Voltage: The battery operates at 4 volts (4V), providing the necessary power to the cache controller system.
- Amperage-Hour (A-HR): The battery has a capacity of 13.5 Ampere-hours (A-HR), indicating the amount of current it can supply over a specified period. A higher A-HR rating signifies a longer duration the battery can sustain the cache memory in the event of a power loss.
Compatibility with EVA Systems
The HP 512735-001 Cache Controller Battery is specifically engineered for compatibility with EVA storage arrays, including models within the 4000, 6000, and 8000 series. These systems rely on this battery to maintain data integrity in their cache memory, ensuring data remains safe during power disruptions.
Importance of Cache Memory Protection
- Data Integrity: Cache memory serves as a temporary buffer for frequently accessed data. Protecting this cache memory with a battery ensures that in the event of a power failure, data waiting to be written to the storage disks remains intact.
- System Reliability: By preserving cached data, the battery helps maintain the overall reliability of the storage system, reducing the risk of data loss or corruption.
Application and Functionality
- Critical Component: The cache controller battery is a critical component of the EVA storage system, providing a failsafe mechanism to safeguard important data during unexpected power interruptions.
- Automated Failover: In case of power loss, the battery allows the cache memory to be powered long enough for the system to complete necessary data transfers or gracefully shut down to prevent data loss or corruption.
Low Voltage Detection Feature
Low Voltage Detection feature for HP 512735-001 4V 13.5A-HR Cache EVA Controller Battery is a mechanism that detects when the voltage of the battery has dropped to a certain level. This feature is designed to prevent the battery from being damaged by over-discharging and to protect the device that the battery is powering. When the low voltage detection feature is triggered, it will typically send a signal to the device to shut down or enter a low-power state, in order to preserve the remaining power in the battery. This feature helps to extend the lifespan of the battery and ensure proper operation of the device.
Low voltage detection is a feature that is used to detect when the battery in the HP 512735-001 4V 13.5A-HR Cache EVA Controller battery is running low on charge. This feature allows the system to alert the user or administrator that the battery needs to be replaced or recharged. The specific implementation of this feature may vary depending on the system, but it is typically accomplished through the use of voltage sensors or other monitoring tools that are built into the battery or the controller. When a low voltage level is detected, the system may take certain actions such as sending an alert, shutting down the system, or switching to a backup power source to prevent data loss.
Temperature and Humidity Range
The temperature and humidity range 512735-001 HP refers to the range of temperatures and humidity levels within which a specific device or product, such as an HP server, is designed to operate safely and effectively. The specific range for this product is not provided, but in general, most electronic devices are designed to operate within a temperature range of 0 to 40 degrees Celsius (32 to 104 degrees Fahrenheit) and a humidity range of 20 to 80% relative humidity. Operating outside of these ranges can lead to damage or failure of the device.
The HP 512735-001 4V 13.5A-HR Cache EVA Controller Battery is a type of battery used to power an HP StorageWorks EVA (Enterprise Virtual Array) controller. The temperature and humidity range refers to the range of environmental conditions in which the battery can safely operate. The specific range will depend on the manufacturer's specifications, but in general, batteries should be kept in a cool, dry place to prevent overheating or damage from moisture. It is always recommended to check the product manual for the specific range of Temperature and Humidity that the battery can handle.
The temperature and humidity range refers to the acceptable operating conditions for the battery. The battery should be stored and operated within a temperature range of -20 to 60 degrees Celsius (-4 to 140 degrees Fahrenheit) and a humidity range of 5% to 95% non-condensing. Operating the battery outside of these ranges may result in decreased performance or damage to the battery.
