Technical details and manufacturing context for Storage Node

Definition

A storage node is an individual computing and storage device that operates as part of a larger parallel storage system. It contains local storage media (such as HDDs, SSDs, or NVMe drives), processing resources, and network interfaces. Within the parallel architecture, multiple storage nodes work collaboratively to distribute data across the system, enabling high-throughput data access, redundancy through replication or erasure coding, and scalable capacity expansion. Each node typically runs specialized software that manages data placement, coordinates with other nodes, and handles client requests. The storage node receives data read/write requests via its network interface. Its local processor executes the storage system's software stack, which determines data placement (often striping data across multiple nodes), manages local storage media, and communicates with other nodes to maintain data consistency, redundancy, and performance. For writes, data may be written locally and replicated to other nodes. For reads, it may serve data directly or participate in parallel read operations from multiple nodes. The node's hardware includes a printed circuit board, semiconductor memory chips (DRAM, NAND Flash), a metal enclosure, and connectors and cables. Typical parameters include storage capacity ranging from 4 to 16 TB per node, 4 to 24 drive bays, drive form factors of 2.5 or 3.5 inches, interface types such as SAS, SATA, or NVMe, maximum sequential read speeds of 500 to 3500 MB/s, write speeds of 400 to 3000 MB/s, network interfaces from 1 to 100 GbE (IEEE 802.3), power consumption of 150 to 500 W, operating temperature of 0 to 40 °C, humidity of 8 to 90 %RH, ingress protection ratings of IP20 to IP40 (IEC 60529), weight of 10 to 30 kg, and dimensions of 430–480 x 88–176 x 500–800 mm. These values are reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier.

Working Principle

The storage node receives data read/write requests via its network interface. Its local processor executes the storage system's software stack, which determines data placement (often striping data across multiple nodes), manages local storage media, and communicates with other nodes to maintain data consistency, redundancy, and performance. For writes, data may be written locally and replicated to other nodes. For reads, it may serve data directly or participate in parallel read operations from multiple nodes.

Frequently Asked Questions

What is a storage node?

A storage node is a computing and storage device that operates as part of a larger parallel storage system. It contains local storage media, processing resources, and network interfaces, and works collaboratively with other nodes to distribute data, provide redundancy, and enable scalable capacity.

What are the typical storage capacities?

The raw capacity per node is typically 4 to 16 TB, but usable capacity depends on the RAID level used. The number of drive bays ranges from 4 to 24, and drive form factors are 2.5 or 3.5 inches.

What interface types are supported?

Interface types include SAS, SATA, and NVMe. NVMe is used for high performance, while SAS/SATA are used for cost efficiency. The network interface can be 1, 10, 25, 40, or 100 GbE, per IEEE 802.3.

What are the environmental operating limits?

The operating temperature range is 0 to 40 °C, and operating humidity is 8 to 90 %RH (non-condensing). The ingress protection rating is IP20 to IP40 per IEC 60529. Always verify these values with the manufacturer for your specific model.
