![]() ![]() Currently, the capacity, along with some increased performance is achieved by adding additional enclosures to a controller system.Īll scaling operations are non-disruptive and when additional systems are added to the cluster, data is automatically balanced across the cluster. Host access is through iSCSI with 10GigE or 1GigE interfaces and Fibre Channel with 16 Gb/s Gen 5 interfaces. Business continuity utilizes replication between Nimble and HPE 3PAR storage systems with Peer Persistence.Īll features are included in the base price of HPE Nimble systems and include data compression, deduplication, snapshots, remote replication, and integration with host-level software such as VMware and Microsoft Windows. ![]() Deduplication is not supported on the HF20C model.Ī triple parity RAID is used across the devices for data protection in case of a device failure. Advanced features of data compression, deduplication, snapshots, encryption, shredding, pinning of volumes in Flash or disk, and asynchronous replication are included in the base system. The HPE Nimble Storage AF80 and HF60 systems support clustering to provide a scale out architecture. The HPE Nimble Storage All Flash systems are designed for data to remain on the SSDs rather than be offloaded to HDDs like the Adaptive Flash models. A base system has a fixed number of devices and depending on the model, additional enclosures may be added. The HPE Nimble Storage Series use standard server hardware and NAND Flash SSDs. All models utilize a similar architecture with different amounts of CPU, DRAM, and Flash SSD within the controller for differentiation. HPE Nimble Storage has multiple models in the two families and the largest in each family can be clustered for four systems. The Adaptive Flash Series, denoted as HF, are Secondary Flash systems which contain SSDs and HDDs as target systems for backup or secondary storage. A copy of all data in the flash layer also remains safely in the disk-drive layer to ensure reliability, but now it can be accessed with the high performance and low latency made possible by flash technology.The HPE Nimble Storage AF All Flash Series of solid-state technology storage systems use flash storage only and have common software with the earlier CS Series that used flash with spinning disk as backing store. CASL also incorporates efficiency features like cloning and integrated snapshots to store and serve more data in less space.ĭata that is frequently accessed is tracked in the Nimble index, which ensures that frequently and recently accessed data is also held in the large adaptive flash layer. ![]() HPE Nimble Storage arrays take advantage of multi-core processors to provide high-speed inline variable-block compression without introducing noticeable latency. Data written to the array is compressed and then stored in the disk-drive layer. CASL leverages the lightning-fast random read performance of flash and the cost-effective capacity of hard disk drives. HPE Nimble Storage solutions are built on the patented Cache Accelerated Sequential Layout (CASL™) architecture. HPE Nimble Storage arrays are engineered for high performance using flash, for low cost using dense, capacity-optimized disks, and for easy installation and administration. ![]()
