Hardware Recommendations
The StorONE system can be deployed in one of three basic architectures:
- Single-node: A single server node that manages both internal drives and external storage enclosures.
- Dual-node HA: Two server nodes with shared access to drives, using one or more external storage enclosures.
- Dual-node HA with replication: Two server nodes that each have internal drives and external storage enclosures, and are configured with replication and automatic failover.
Hardware requirements
The basic hardware building blocks of a StorONE deployment include:
- Server nodes
- Storage enclosures
- Data connectivity
- Drive connectivity
| Hardware | Description |
|---|---|
| Server node | Intel- or AMD-based standard commodity servers from leading manufacturers with no specially-built components. |
| Storage enclosure | Standard serial-attached SCSI-based (SAS) storage enclosure that supports 12-GB SAS connectivity. |
In addition, the server nodes require the following internal hardware components:
| Internal hardware components | Description |
|---|---|
| Network interfaces | To meet the storage demands of different types of servers and operating systems clients, the StorONE appliance supports Ethernet, Fibre Channel, Infiniband, and NVMe-oF. |
| Ethernet interfaces | Depending on your infrastructure, StorONE appliance servers require the installation of standard Ethernet NICs (10Gb, 25Gb, 40Gb, 50Gb ,100Gb, 200Gb). |
| Fibre Channel interfaces | If your infrastructure uses Fibre Channel, install standard FC HBAs (8Gb, 16Gb, 32Gb). |
| InfiniBand interfaces | Depending on your infrastructure, install standard InfiniBand NICs. |
| NVMe-oF interfaces | Use standard Ethernet NICs that support NVMe-oF/TCP or NVMe-oF/RDMA. |
| SAS interfaces | Standard non-RAID SAS HBAs (host bus adapters) for each external disk enclosure. |
StorONE recommends using at least one SAS HBA (PCIe controller with 2x SAS ports) for each enclosure. In high availability systems, each disk enclosure should be connected to two SAS controllers in a star topology. If necessary, in cases where the SAS controller is not expected to be a performance bottleneck (such as in HDD-based systems), you can connect each SAS disk enclosure in a daisy-chain topology.
Single-node appliance
A configuration that consists of a single server is referred to as a single-node appliance. This configuration is suitable for small to medium-sized environments that have medium performance requirements and small to high-capacity storage needs. It can also be used as a backup target, in remote offices, or as a disaster recovery solution.
Dual-node HA appliance
A configuration that consists of two servers connected to each other via a high-availability (HA) interconnect is referred to as a dual-node HA appliance. In this configuration, each of the servers runs the S1 operating system and coordinates load sharing and failover.
