Flash Accel features intelligent end-to-end data coherency, cache persistence, and compatibility with Windows Server Failover Clustering.
- Data coherency. Flash Accel offers the highest level of data integrity without compromising system performance. After a SnapRestore reverts data in back-end storage, for example, Flash Accel invalidates any cache data written after the backup. And it does so with negligible impact on system performance.
- Cache persistence. In a Flash Accel-enabled system, the cache is kept "warm" after a server restart or a storage system operation like SnapRestore. It remains populated with data from application read and write activity, so that caching can resume where it left off.
- Windows Server Failover Clustering. A Flash Accel-enabled system is compatible with Windows Server Failover Clustering, ensuring high availability of application cache across the failover cluster. The cache must be rewarmed after failover.
In addition to these major features, Flash Accel
offers the following:
- Support for PCIe cards and server SSDs.
- Up to 4 TB of cache per server.
- Support for both 7-Mode and clustered Data ONTAP.
- Compatibility with NetApp management products.
- Cache disks over iSCSI or FC.
