Features

Accessory:
Flash based DDR backup module for Adaptec 6405, 6805, 6445, 6805T controllers
(Zero Maintenance Cache Protection)

Enabling the onboard cache on a RAID controller card signifi cantly 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. Lithium-ion battery backup units (BBUs) are traditionally employed to protect cached data on RAID controllers, but they are not an optimal solution. BBUs have hidden costs that can drastically increase a RAID controller's Total Cost of Ownership (TCO) by thousands of dollars per year, including monitoring and maintenance expenses. Over time, all batteries lose their ability to hold a charge, so BBUs need to be periodically replaced and the old units must be disposed of in an environmentally-responsible manner. Once installed, a new BBU will take several hours to reach a full charge, leaving the write cache turned off and aff ecting performance. To make matters worse, even a typical BBU needs to test capacity regularly and performs suboptimal during those test periods. Additionally a fully-charged BBU can only preserve data for a maximum of 72 hours during a power loss before the battery power depletes. Zero-Maintenance Cache Protection Now in its second generation, Adaptec ZeroMaintenance Cache Protection (ZMCP) drastically reduces a controller's TCO by using fl ash memory instead of BBUs to provide full protection of cached data without the monitoring, maintenance, replacement, and disposal requirements and costs associated with Lithium-ion batteries. Adaptec Flash Module 600 ZMCP is available for Adaptec Series 6 and 6T controllers as an optional Adaptec Flash Module (AFM 600) and is preinstalled on all Series 6Q models supporting Adaptec maxCache SSD caching feature. Th e modular aspect of the AFM 600 gives data centers the fl exibility of adding ZMCP at any time, or not adding it at all, depending on budgets and requirements. Competitive alternatives are built into the controller cards - forcing data centers to purchase a new card in order to add cache protection. Th e AFM 600 features 4GB of NAND fl ash memory and super capacitor technology that work together to save cached data in the event of system power loss. Th e super capacitor charges while the system is booting to provide instant cache protection upon startup. When the module detects loss of power, the super capacitor keeps critical parts of the controller active long enough to allow data to be copied from the onboard controller cache to the fl ash memory. Once the data has been copied, the fl ash memory can store it for years without power, allowing for less urgency in disaster recovery plans than the 72-hour BBU threshold. When power is returned to the controller, the data in the fl ash memory is copied back to the onboard controller cache and operation resumes as normal with all outstanding I/O requests intact.
