uses OS called NetApp Element Software (formally SolidFire Element OS) based on Linux and designed for SSDs and scale-out architecture with the ability to expand up to 100 nodes and provide access to data through SAN protocols iSCSI natively and Fiber Channel with two gateway nodes. Element OS provides a REST-based API for storage automation, configuration, management, and consumption. SF node H610S has 12 2.5" NVMe SSD drives and can install only Element version 10.4, while previous models have 10 SSD drives. Element SW version 11, will not support FC. SolidFire uses iSCSI login redirection to distribute reads and writes across the cluster using helix algorithm. This architecture does not have disk shelves like traditional storage systems and expands with adding nodes to the cluster. Each node has pre-installed SSD drives. Each node can have only one type of SSD drives with the same capacity. Each SolidFire cluster can have a mix of different node models and generations. Element X uses the replication factor of 2, where blocks of data spread across the cluster which has no performance impact but require more space in contrary to Erasure Coding technology. Such architecture allows users to expand performance and capacity separately as needed. Also, SolidFire has the ability to set three types of QoS for its LUNs: minimum, maximum and burst. Burst is used as credits which were not used by the LUN while it was not received its maximums. Element X available as software-only on commodity servers. SolidFire systems using S3 protocol could backup data to an Object storage systems like StorageGRID. SolidFire could replicate data with SnapMirror protocol to ONTAP systems and starting with Element OS 11 to Cloud Volumes ONTAP. VEEAM backup and Replication 9.5 Update 4 will implement seamless integration with NetApp HCI and Solidfire provide application consistent storage snapshot capabilities, Instant VM Recovery, and Single Item Restore for some applications. CommVault Simpana also provides application-consistent storage snapshot capability for NetApp HCI and Solidfire. All HCI configurations require at least 4 10/25 Gbit/s ports for connections until Element OS 11, where two ports are enough. StorageGRID StorageGRID is a software-defined storage system which provides access to data via object IP-based protocols like S3 and OpenStack Swift. It is available in the form of hardware or as software. A node in a StorageGRID cluster is an appliance, virtual machine or docker container. StorageGRID is a geo-dispersed namespace clustered storage
