p p enabling the onboard cache on a raid adapter card signi 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 . p p lithium ion li ion battery backup units bbus are traditionally employed to protect cached data on raid adapters . once installed a new bbu will take several hours to reach a full charge . during the charge cycle write cache is unprotected i.e. turned o which adversly a ects the raid adapters performance . a typical bbu requires routine capacity testing and performs sub optimally during those test periods . lastly a fully charged bbu can only preserve data for a maximum of 72 hours during a power loss before the battery power depletes . p p b u technical information u br b br b memory size b 2 gb br b data backup type b flash br b application usage b raid controller br br b u physical characteristics u br b br b weight approximate b 13.76 oz br br b u miscellaneous u br b br b compatibility b p b adaptec raid adapters b p ul li 72405 li li 71685 li li 71605 li li 7805 li li 71605q li li 7805q li ul br b green compliant b yes br b green compliance certificate authority b rohs br br b u warranty u br b br b limited warranty b 3 year
