2-port card | PowerStore 1000 and higher models require two 100 GbE optical QSFP port card to support NVMe expansion shelves. |
4-port card | Card for each node that provides four ports. Options include 25 GbE optical and 10 GbE Base-T. The PowerStore 500 requires the 25 GbE card to support NVMe expansion shelf. The four-port mezzanine card supports federate storage (to cluster multiple PowerStore appliances) and file storage. PowerStore 3.0 models support a new 100 GbE four port card in I/O module for slot 0 in PowerStore x000 and x200 models. |
Appliance | The appliance is the base enclosure plus all expansion enclosures connected to the base enclosure. |
Base enclosure | A hardware chassis that consists of two nodes, two or four NVMe NVRAM drives, and up to 21 NVMe SSD or NVMe SCM drives. |
Cluster | A group of one to four PowerStore appliances. PowerStore X 2.0 models could not be clustered with multiple appliances. However, PowerStore T 2.0 and PowerStore 3.0 models are expandable by adding more appliances (up to four total). |
Node | Component within the base enclosure that contains processors and memory. |
Expansion enclosure | Enclosures that can be attached to a base enclosure to provide extra storage in the form of either NVMe or SAS drives. A maximum of three 25-drive expansion shelves are supported. Depending on the PowerStore model, the expansion enclosure must either be a NVMe expansion enclosure, or a SAS expansion enclosure. Mixing expansion enclosure types is not supported. PowerStore 3.0 models x200 support only NVMe expansion shelves. PowerStore 2.0 models x000 support only SAS expansion shelves. |
Embedded module | With PowerStore 3.0 x200 models, an improved-embedded module v2 is embedded on each node providing: - Management and service ports
- Two NVMe expansion ports (100 GbE, QSFP BE-ports)
- Four ports for front-end connectivity
The PowerStore 3.0 500 model does not have an embedded module. It uses a four-port 25 GbE optical mezzanine card. Ports 0 and 1 are used for the system bond. The bonded ports are used for federation and NAS. Ports 2 and 3 of the four mezzanine ports are required and reserved for back-end connectivity to support NVMe expansion shelves. With PowerStore 2.0 x000 models, the embedded module v1 is needed for management and service, and SAS expansion (SAS BE-ports) and only available and required on PowerStore x000 models. For PowerStore 2.0 500 model, the four-port 25 GbE optical mezzanine card on embedded module v1 is not required. It is only required if the system will be configured for: - Unified storage
- Federated storage (clustering of multiple appliances)
|
Node | The component within the base enclosure that contains processors and memory. Each appliance consists of two nodes. |
PowerStore Manager | PowerStore Manager is a web-based user interface (UI) for storage management. |
NVMe over Fibre Channel (NVMe/FC) | NVMe/FC allow hosts to access storage systems across a network fabric with the NVMe protocol using Fibre Channel as the underlying transport. |
Dynamic Resiliency Engine | System functionality that manages the hard drives to provide capacity, performance, and fault tolerance. |
Storage resource | A storage resource and be a volume, file system, NAS server, or virtual volume. |
Hypervisor | Computer software, firmware, or hardware that creates, manages, and runs the virtual machine. |
Scale-out | The ability to cluster multiple PowerStore appliances together. |
Scale-up | The ability to add additional disk enclosures, up to a maximum of three, to a PowerStore appliance. |
