Adaptec® Flash Module 700 Kit: AFM-700
3rd Gen Zero-Maintenance Cache Protection
Maximum Data Protection and Cost Savings
Enabling the onboard cache on a RAID adapter card significantly enhances performance — especially in RAID 5 and RAID 6 scenarios — by accommodating both read caching and write caching of data. But data stored in the cache for write caching can be lost if the cache is not protected against a power or system failure. Now in its third generation, Adaptec Zero Maintenance Cache Protection (ZMCP) from Microsemi drastically reduces a RAID adapter’s TCO through the use of flash memory versus Li-ion batteries.
Designed for Adaptec RAID Adapters
The AFM-700 for ZMCP is included with the Series 8Q (12 Gbps). The Adaptec 81605ZQ and 81605Z have the flash backup embedded on the board. ZMCP is available as an option for Series 8 (12 Gbps) and Series 7 (6 Gbps) RAID adapters with the AFM-700 kit, which includes a mounting plate to secure the cap module to an unused PCIe slot.
Advanced Technology
The AFM-700 features NAND flash memory and super capacitor technology that work together to save cached data in the event of system power loss. The super capacitor charges while the system is booting. When the module detects loss of power, the super capacitor keeps critical parts of the RAID adapter active long enough to allow data to be copied from the onboard adapter cache to the flash memory. The flash memory can store data for years without power. When power is returned, the data is copied back to the onboard adapter cache and operation resumes as normal with all outstanding I/O requests intact.
Ease of Use
With ZMCP’s new monitoring features (Real-time Health and Instant Capacity Monitoring), data center administrators can instantly check the temperature, capacity and remaining lifetime of the super capacitor through Adaptec maxView Storage Manager, a web-based interface.
