ATTO CacheAssure
Maintenance-Free Cache Memory Data Protection

Power and system failures can permanently lose data that is located in cache memory. Traditionally, battery backup units (BBU) have been used to protect and recover cached data but they require constant monitoring, maintenance and replacement and only protect data for up to 72 hours after a failure. What if there was a better more cost-effective solution?

CacheAssure uses supercap technology instead of a battery to protect your cached data. Save time and money by eliminating the need to install, monitor, maintain, dispose, and replace batteries, plus with CacheAssure, taking down the system for battery replacement is no longer a requirement.

Available as an option on all ExpressSAS RAID adapters.

No Batteries, Lifetime Backup

CacheAssure uses supercap technology instead of a battery to protect your cached data. Save time and money by eliminating the need to install, monitor, maintain, dispose, and replace batteries, plus with CacheAssure, taking down the system for battery replacement is no longer a requirement.

Typical battery backup units last about 1 or 2 years and only provide up to 72 hours of data protection. With the combination of NAND flash and super capacitors, ATTO's CacheAssure™ Technology provides full protection within minutes of installation. Contents in cache memory get saved immediately in the event of a system failure or power loss and can remain protected for up to 10 years!

ATTO's RAID products with CacheAssure Technology deliver a long-lasting and reliable cached data protection solution all without the worries associated with battery-based technology.

The Problem

A system power failure has just occurred and the cached data in the RAID adapter's memory is in danger of being permanently lost. Traditionally, a battery backup unit installed on the adapter provided a means of recovering cached data for up to 72 hours. But is that the best possible solution? While it's true that the on-board memory is maintained until the power is restored, the battery backup unit is not the ideal solution to this problem.

Using battery backup, while oftentimes effective, also has limitations. Batteries are relatively expensive and inconvenient (they must be purchased more frequently and separately from the RAID adapter), they increase costs (inventory, monitoring and replacement), and there is a considerable restriction on how long the cached data is protected. These risks and limitations are enough of a reason to consider alternatives to traditional battery backup processes.

The Solution

CacheAssure technology is a maintenance-free, nonvolatile cache data protection module that safeguards against the loss of cached data during a power or system failure. Available on ATTO technolody Inc. ExpressSAS 6Gb/s RAID adapters, CacheAssure is a more reliable data-recovery alternative to battery backup units.

CacheAssure is NOT a battery; it is based on cacitor technology that does not require lengthy charge times to start protecting cached data.

In the event of a power or system failure, CacheAssure instantly detects the failure and preserves the cached data in nonvolatile memory on the RAID adapter, allowing users to maintain their data until power is restored. CacheAssure provides quick and easy access to cached data upon system re-boot by keeping the data upon system re-boot by keeping the data in nonvolatile memory until all the drives are ready to accept the transfer and data is verified. Competitive solutions immediately flush the cached data upon system re-boot, risking data loss in the event the drives are offline and not available.

ATTO ExpressSAS 6Gb/s SAS/SATA RAID adapters provide high-performance connectivity for bandwidth-intensive data transfers. CacheAssure technonlogy is specifically designed for environments that demand the highest levels of consistent I/O performance with the assurance that their critical data won't be lost during a power or system failure. These environments include financial, healthcare, educational, scientific and other similar institutions.

ATTO RAID adapters with CacheAssure technology deliver a long-lasting and reliable cached data protection solution for today's data center.

ATTO's CacheAssure Technology

The Benefits

Lifetime Backup
CacheAssure protects cached data for up to 10 years, offering a more substantial return on investment. Typical battery backup units last approximately one or two years and only provide upwards of 72 hours of data protection.

Immediate RAID Protection
Maintain productivity levels with immediate response times when there is a power system failure (batteries require up to eight hours of charging time). This provides ease-of-mind over long holiday weekends or extended periods of facility closure.

Zero Maintenace
Monitoring the charge levels of batteries is an ineffective use of resurces and the replacement of batteries, which age and wear out more rapidly, often requires system downtime. CacheAssure eliminates these concerns.

Environmentally-Friendly
CacheAssure is a battery-less technology that is not required to adhere to strict disposal and shipping regulations. This reduces the costs and the negative environmental effects associated with battery use and disposal.

Quick Charging
CacheAssure is ready to protect your data within minutes, unlike batteries which take hours to charge.
