Increase performance. Reduce downtime.
ATTO ExpressSAS RAID HBAs featuring Adaptive Path Optimization, have built-in intelligence to recognize that there are two paths to every drive, and will direct I/O accordingly. If a path to a controller goes down, or is taken off-line for maintenance, I/O will automatically be routed down the remaining path. If the path is restored, the adapter automatically reconfigures to send data down both paths. ATTO automatically senses the paths to the storage, configures primary and secondary access on a disk-by-disk basis and balances I/O so that all paths are running as efficiently as possible.
No batteries. Lifetime backup.
ATTO ExpressSAS RAID HBAs featuring CacheAssure use supercap technology instead of a battery to protect your cached data.

Advanced Data Streaming (ADS) Technology
Latency Management for the Highest Consistent Performance
ATTO’s exclusive Advanced Data Streaming (ADS) is a proprietary technology that is built into ATTO Host Adapters and RAID Storage Controllers, designed to manage latency in high-bandwidth work environments.
ADS provides controlled acceleration of data transfers by utilizing a combination of features to move large amounts of data faster and more efficiently, maintaining the highest consistent performance.
From high I/O transactional applications to large bandwidth real time streaming, ADS reduces project interruptions by maximizing the number of transactions that can be processed by the CPU, resulting in better overall system performance.
ADS Technology is incorporated into ATTO’s Celerity Fibre Channel Host Adapters, ExpressPCI SCSI Host Adapters, ExpressSAS SAS/SATA Host and RAID Adapters and FastStream RAID Storage Controllers.
- Optimized Driver Algorithms - Many generations of driver codes maximize stability and optimization for workgroup applications
- Bus Mastering - Relieves CPU burden by transferring data directly between ATTO products and system memory
- Tagged Command Queuing - Multiple I/O commands can be processed in any order, improving read and write requests to hard drives
- Disconnect/Reconnect - Eliminates wait time between ATTO products and other devices, enabling dynamic sharing of bus bandwidth
Drive Assessment and Latency Management for Enhanced Performance
When reading or writing data to storage or RAID devices, if one or more drives are not performing as expected due to slow spots or bad sectors, drive performance will be compromised. Common errors within drives can cause performance degradation or premature failure of the drives that can result in loss of critical assets.
- IT managers and financial institutions need assurance that data is securely backed up and RAID groups are online without unnecessarily running in degraded mode.
- Broadcast providers are highly concerned with data loss which can negatively impact play-to-air environments. Video-on-demand providers need constant (24/7) access to their media.
- Video Editing customers can’t afford to have projects interrupted because of dropped frames, or data loss due to premature drive failures and the time and expense involved in replacing those drives.
DriveAssure is a specialized drive assessment and latency management feature, available on ATTO FastStream RAID Storage Controllers and ExpressSAS RAID Adapters, that provides bounded latency through proprietary algorithms and user controls. DriveAssure prevents premature drive failures and slow downs to ensure uninterrupted access to data.
Proactive Measures: Unlike competitive products that fail a drive after a few unsuccessful retries, DriveAssure initializes (scrubs) and performs periodic drive scans to search for bad sectors and repairs them prior to a catastrophic failure. DriveAssure has built-in intelligence that performs parity verification and regularly monitors drive I/O performance.
Corrective Measures: During normal operation proprietary algorithms handle errors on drives due to slow spots or bad sectors. Through active monitoring of drive response times, retries of reads and writes, and alternative methods of data generation, DriveAssure makes certain that data is returned without failing the drive.
- Enhanced Productivity - Systems run longer, faster and smoother with uninterrupted data transfer.
- Increased Data Protection - The potential for lost data or dropped frames is significantly minimized.
- Cost Savings - Unnecessary drive replacements are eliminated, saving time and money on new drives and the labor involved with initializing and rebuilding RAID groups.
- Faster Reads and Writes - With a lower occurrence of drive failures, bandwidth is directed to where it is needed most - application performance - not RAID group rebuilds and data backups.
NV Cache Data Protection Module
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.
CacheAssure Technology is a maintenance-free, NV cache data protection module that safeguards against the loss of cached data during a power or system failure. Available on ATTO's EpxressSAS 6Gb/s RAID adapters and FastStream RAID Storage Controllers, CacheAssure is a more relable data-recovery alternative to battery backup units. CacheAssure is NOT a battery, It is based on capacitor 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 adaper or storage controller, allowing user 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 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's ExpressSAS 6Gb/s SAS/SATA RAID adapters and FastStream RAID Storage Controllers provide high-performance connectivity for bandwidth-intensive data transfers. CacheAssure Technology 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's RAID products with CacheAssure Technology deliver a long-lasting and reliable cached data protection solution for today's data center.
CacheAssure keeps data secure in nonvolatile memory
- Lifetime Backup - CacheAssure protects cached data for up to 10 years, offering a more substantial return on investment. Typical battery backup units last approximately 1 or 2 years and only provide upwards of 72 hours of data proteciton.
- Immediate RAID Protection - Maintain productivity levels with immediate response times when there is a power system failure (batteries require up to 8 hours of charging time). This provides ease-of-mind over long holiday weekends or extended periods of facility closure.
- Zero Maintenance - Monitoring the charge levels of batteries is an ineffective use of resources 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.
Data Recovery Mode
Mechanism that increases the probability of fully or partially recovering data that is lost due to a disk failure and offline RAID group.
Efficiently Share Memory
ATTO ExpressSAS RAID HBAs are optimized to ensure that driver resources are located close to the system I/O. In addition, they support NUMA-aware applications and operating systems. NUMA is a system design that allows multiple processors in the same server to efficiently share memory. This reduces latency and increases I/O performance - especially important for data mining, business analytics and other processor-intensive applications.
