Maximum Data Protection and Cost Savings for Adaptec 
Series 7 and Series 7Q RAID Adapters

Enabling the onboard cache on a RAID 

adapter 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 (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 off ), which adversly aff ects the 

RAID adapter’s 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. 
Li-ion BBUs have hidden costs that can 

drastically increase a RAID adapter’s Total 

Cost of Ownership (TCO) by hundreds 

of dollars per year through monitoring, 

maintenance, replacement, and disposal 

expenses

Now in its third generation, Adaptec Zero- 

Maintenance Cache Protection (ZMCP) 

drastically reduces a RAID adapter’s TCO 

through the use of fl ash memory versus 

Li-ion batteris. Th ese fl ash modules provide 

full protection of cached data without the 

costs associated with Li-ion batteries.

ZMCP is available for Adaptec Series 7 

adapters (72405, 71685, 71605, 7805) as an 

optional Adaptec Flash Module (AFM-700) 

and is preinstalled on all Series 7Q models 

supporting Adaptec’s maxCache 3.0 SSD 

caching feature. Th e modular aspect of the 

AFM-700 gives data centers the fl exibility 

of adding ZMCP at any time, depending 

on their needs and budgetary parameters. 

Competitive alternatives force data centers 

to purchase a new card in order to add cache 

protection, as certain functionality is built 

into their base adapter.
Th e AFM-700 features 2GB 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 RAID adapter active long 

enough to allow data to be copied from the 

onboard adapter cache to the fl ash memory.
Once the data has been copied, the fl ash 

memory can store it for years without 

power.  When power is returned to the 

RAID adapter, the data in the fl ash memory 

is copied back to the onboard adapter cache 

and operation resumes as normal with all 

outstanding I/O requests intact.
Lastly, with its 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 that makes 

it simple to view, monitor, and confi gure 

all Adaptec RAID adapters in a system, 

without disrupting operations or impacting 

performance.
