Dell Nimble Storage CS1000 of CS series arrays is built on Nimble’s CASL architecture (Cache Accelerated Sequential Layout). The CASL architecture utilizes inline compression. which stores data in variable-size blocks in real-time. HPE Nimble Storage CS1000. this method of compression is 2-4x more effective with no latency when compared to other architectures. that store data in fixed-sized blocks. In addition to offering more than double the compressions. a copy of hot active hot data is stored in flash memory. This enables lightning-fast reads of your data that are laid out sequentially on High-Capacity Disks.
