Cache Accelerated Sequential Layout (CASL™) Architecture
Inline Compression: Un­like existing architectures that store data as fixed-size blocks, Nimble CASL stores data as variable-size blocks, enabling real-time 2-4x data com­pression with no added latency
Optimized Data Layout: A copy of active “hot” data is held in flash memory, enabling fast reads, while all data is stored in cost-effective, high-capacity disk. Data is laid out sequentially, enabling fast writes to flash and disk.
Intelligent Index: CASL’s intelligent index automatically tracks hot data blocks and instantly responds to workload changes.
Instant, Integrated Backups: 60-90 days of compressed, incremental, snapshots are captured on high-capacity disk at pre-con­figured intervals. The snapshots are highly space efficient, and have zero performance impact on application performance, allowing frequent recovery points.
Efficient Offsite Replication: Compressed block level changes are copied to a remote Nimble array for cost-effective disaster recovery.
