Maximum Data Protection and Cost Savings
Enabling the onboard cache on a RAID adapter card significantly enhances the
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, Microsemi Adaptec Zero-Maintenance
Cache Protection (ZMCP) drastically reduces a RAID adapter’s total cost of
ownership (TCO) through the use of flash memory versus lithium-ion batteries.
Designed for Microsemi Adaptec RAID Adapters
The AFM-700 for ZMCP is included with the Series 8Q (12 Gbps). The
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 technologies
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
Data center administrators can use ZMCP's new real-time health and instant
capacity monitoring features to instantly check the temperature, capacity,
and remaining lifetime of the super capacitor through Microsemi's Adaptec
maxView Storage Manager, a web-based interface.

Third-Generation Zero-Maintenance Cache Protection
Backup Battery Units (BBUS) vs. ZMCP: Maintenance Requirements
Flash Module 700 (AFM-700)
Lithium-ion BBUs ZMCP
Batteries must be “conditioned” during initial deployment, adding custom steps and several hours to the
deployment process. No action required
Battery performance must be continually monitored so that failing batteries can be replaced. No action required
A failed battery must be replaced within 72 hours, and sometimes sooner. No action required
Batteries must be replaced on a regular maintenance cycle, so replacement batteries must be kept available at
each location and maintenance staff must be on-site or on-call. No action required
Replacement batteries age even when on the shelf, so a continual purchasing process must be developed and
implemented. No action required
Lithium-ion batteries must be properly disposed. A process to dispose of the hazardous material must be
created, staffed, and funded. No action required
Reasons to buy
The AFM-700 provides Zero-Maintenance Cache Protection for Series 8, Series 8Q/8Z (12 Gbps), Series 7, and
Series 7Q (6 Gbps) RAID adapters to protect data in the controller cache without incurring monitoring, maintenance,
replacement, or disposal costs.
Customer needs Solutions that require advanced protection of data and reduced total cost of ownership (TCO).
