Cisco 512MB Flash Backed Write Cache

The Cisco 512MB Flash Backed Write Cache is a vital upgrade for RAID controller environments, purpose-built to boost performance while safeguarding data integrity. This high-efficiency cache module integrates seamlessly behind compatible Cisco controllers to absorb write-heavy workloads, dramatically reducing write latency and improving overall I/O throughput. Engineered for enterprise storage deployments, it empowers organizations to run demanding databases, virtualization suites, and analytics workloads with greater confidence, knowing that data is processed swiftly and protected against unexpected power events. By adding this flash-backed cache, you extend the life of your storage infrastructure and unlock consistent performance gains without replacing your existing controller or storage array.

• Boosted write performance for demanding workloads. The 512MB flash-backed cache acts as a fast, persistent buffer that absorbs burst writes, allowing the RAID controller to stage writes quickly and flush them to disk more efficiently. This reduces queue depth pressure, minimizes write stalls, and delivers higher sustained throughput for transaction-heavy applications, large-scale databases, and I/O-intensive virtualization environments.
• Data safety with non-volatile write caching. Designed to preserve data in transit, the flash-backed cache provides protection against power loss or unexpected outages. Writes staged in the cache can be safely committed to the storage array once power is restored, helping prevent data loss and ensuring more reliable recovery after outages than traditional volatile caches.
• Enterprise reliability and Cisco engineering. Built by Cisco for enterprise deployments, this cache module adheres to Cisco’s rigorous quality and compatibility standards. It integrates with Cisco RAID controllers and storage ecosystems, delivering predictable performance and long-term compatibility, backed by Cisco support and firmware updates.
• Efficient upgrade with minimal downtime. Adding the 512MB cache is a non-disruptive optimization for compatible controllers. It leverages existing infrastructure to deliver a measurable performance uplift without the need for a full controller replacement, reducing total cost of ownership while extending the life of your storage solution.
• Ideal for databases, virtualization, and analytics. By accelerating write paths and stabilizing I/O under heavy load, this cache module helps databases handle higher transaction rates, virtualization platforms maintain snappy response times, and analytics workloads complete more quickly, improving service levels and user experience.

how to install Cisco 512MB Flash Backed Write Cache

• Power down the server, unplug power cords, and ground yourself to prevent static discharge before handling the module.
• Identify the compatible Cisco RAID controller slot and confirm your controller model and firmware version meet the cache module requirements.
• Open the chassis or access panel and locate the proper expansion slot designated for cache modules compatible with Cisco controllers.
• Align the cache module with the slot connectors, insert firmly, and secure any retention screws or latches as required by your hardware.
• Reconnect power, boot the system, and verify that the RAID controller POSTs successfully and recognizes the new 512MB cache module. If prompted, apply any available firmware updates recommended by Cisco.

Frequently asked questions

• Q: What is the Cisco 512MB Flash Backed Write Cache? A: It is a 512 MB flash-backed cache module designed to sit behind a Cisco RAID controller, accelerating write operations while protecting data during power events to improve overall storage performance and reliability.
• Q: What benefits does it bring to storage performance? A: By absorbing and quickly staging writes, the cache reduces write latency, increases sustained I/O throughput, smooths peak bursts, and helps databases and virtualization platforms deliver faster response times under heavy load.
• Q: Is this cache compatible with all Cisco RAID controllers? A: It is intended for use with specific Cisco RAID controllers and select Cisco storage solutions. Always consult the compatibility matrix for your controller model and firmware version to confirm support.
• Q: How does power loss protection work? A: The flash-backed cache preserves data in non-volatile memory so in-flight writes are not lost during power outages. When power returns, cached data is safely flushed to disk, helping prevent data corruption and loss.
• Q: How do I obtain warranty or support? A: Warranty terms and support are provided by Cisco. Check your purchase documentation or contact Cisco Support for coverage details, service options, and firmware update guidance.
