A SolidFire cluster is the hub of the SolidFire Storage System and is made up of a collection of SolidFire nodes. These nodes are connected over a 10Gb Ethernet network to create a storage cluster ranging from 4 to 100 nodes. The clusters can be expanded by simply adding new nodes as business and application demands dictate. There are two fundamental types of the nodes:
Storage node is a collection of volume drives that communicate with each other through the CIPI Bond10G network interface. Volume drives in the nodes contain data blocks and metadata space for data storage and data management. You can create a cluster with new storage nodes, or add storage nodes to an existing cluster to increase storage capacity and performance. Fibre Channel node provides connectivity to a Fibre Channel switch, which you can connect to Fibre Channel clients. Fibre Channel nodes act as a protocol converter between the Fibre Channel and iSCSI protocols; this enables you to add Fibre Channel connectivity to any new or existing SolidFire cluster.
The SolidFire storage system scales up to 100 nodes, provides capacity from 35TB to 3.4PB, and can deliver between 200,000 and 7.5M guaranteed IOPS to more than 100,000 volumes / applications within a single system - increasing overall business productivity through consolidation, automation and granular scalability. These clusters instantly and automatically grow the capacity and performance of the entire system.
If the volume drives and the block drives in the nodes of the cluster lack space, then the data cannot be stored in the target storage system which may lead to critical data loss. To avoid this and to ensure peak performance of the cluster, it is mandatory to monitor the space utilization of the drives periodically. The SolidFire Cluster Capacity test helps administrators in this regard!
This test reports the space available in the volume drives and space that is utilized in the volume drives. This test also reports the utilization of provisioned space. By closely monitoring the space utilization of the volume drives and the block volume drives, administrators may be alerted to potential space crunch.
Outputs of the test : One set of results for the target SolidFire storage system.
